    A coupled analysis of the reaction kinetics and microstructural changes of Fe2O3/Al2O3 oxygen carriers during redox reaction cycles for chemical looping systems was conducted. The microstructural changes in the oxygen carrier particles were investigated using an image analysis method with cross-sectional backscattered electron images, and microstructural information such as the particle size, porosity, and two-phase boundary between the iron oxide and pores was obtained. The microstructural changes and the degradation kinetics during redox cycles were investigated under various operating conditions (reaction temperatures, reduction times, oxygen partial pressures during the oxidation process, and weight ratios of the oxygen carriers). The degradation coefficient and the reaction enthalpy of the particles in the oxidation process are linearly related, implying that increasing the local temperature of the oxygen carriers causes the coarsening of iron oxide particles via sintering and microstructural changes. Our analysis contributes to the design of highly stable oxygen carrier particles and the improvement of the operating conditions for chemical looping systems.

    Improvement in the reduction kinetics and stabilities resulting in longer lifetimes are required for practical application of energy conversion and storage systems using redox reaction of metal oxides such as chemical looping systems. It has been previously reported that using oxide ion conductors as supports can improve the redox reactions of metal oxides. To evaluate which physical properties (such as oxide ion transport and electron transport) can affect the redox reaction kinetics of Fe2O3, reduction kinetic analyses of Fe2O3 reduction by hydrogen were performed. The experiments were conducted using various supports such as CaTi(1-x)Fe(x)O3 (CTFO, as a mixed ionic and electronic conductor), yttlia-stabilized zirconia (YSZ, as a pure oxide ionic conductor) and Al2O3 as a reference (insulator). The results showed that reduction of Fe2O3 with CTFO or YSZ as a support was greatly improved compared with Al2O3. Oxidation measurements of the Fe/supports by water vapor, i.e. hydrogen production by a steam-iron reaction, showed that CTFO was highly effective at increasing oxidation. Modeling analyses based on the oxygen chemical potential distributions of the Fe2O3/supports were also performed to analyze the effect of the supports quantitatively. Calculations assuming high electron and oxygen transport at the interface supported the experimental results. The results suggest that the transport properties at the interface were derived from a highly conducting phase and that oxide ionic conductivity is the predominant factor in the improvement. Sensitivity analysis using various parameters was also conducted and the mechanism for the improvements was discussed.

    Improvement of redox reaction kinetics is important for the application of metal oxide redox reactions in energy conversion systems such as chemical looping systems and hydrogen storage. In this study, we focused on physical properties in supports that can affect the redox reaction kinetics of metal oxides. The redox reaction of iron oxide by hydrogen and water vapor was studied with various support materials, ZrO2. CeO2, yttria-stabilized zirconia (YSZ) and gadolinia-doped ceria (GDC), which have different physical properties such as oxide ion and electronic conductivities. Oxide ion conductors such as YSZ and GDC clearly increased the rate of Fe2O3 reduction (Fe2O3 -> Fe3O4 -> FeO -> Fe). This result suggests that oxygen vacancies and good oxide ion transport properties in the supports may enhance removal of oxygen from iron oxide. In addition, CeO2 and GDC significantly improved the reduction kinetics in the reduction step from FeO to Fe. Furthermore, it was found that these supports have an effect on the oxidation reaction kinetics of iron by water vapor in comparison with ZrO2; that is, they increase the rate of the steam-iron reaction for hydrogen production. The mechanism of the improvement was discussed in terms of oxide ion and electronic conductivity in the supports and water dissociation on the support surfaces. (C) 2014 Elsevier Ltd.

    To develop new chemical-energy conversion and storage systems using metal oxides, the kinetics of iron oxide (Fe2O3) reduction by humidified methane using an oxide ion conductor, CaTi1-xFexO3-delta (CTFO), as a support was analyzed. Significant improvements in Fe2O3 reduction rate and lattice oxygen utilization were observed using CTFO, which may be induced by rapid ion transport at the interface between Fe2O3 and CTFO.

    The chemical looping reaction is applied to the combustion and gasification of coal for effective energy conversion. The reduction of metal oxide is examined in the fixed/fluidized bed of 20 mm I.D. and 1120 mm high. As a lattice oxygen carrier, iron oxide is used and coated on the porous alumina of 0.2 mm mean diameter. Taiheiyo coal of 0.5 g is dropped into the test section and gas production profiles were measured with the temperature range 793 K through 983 K. Initial stage of the reaction, only carbon dioxide is observed, while the hydrogen is produced simultaneously for the insufficient amount of lattice oxygen. Hydrogen yield is about 2.5 times of the carbon content and this exceeds 2.0 which is obtained from the complete reactions of the Water gas and Shift reactions. The extra hydrogen is produced from the hydrogen contained in coal and it may give higher cold gas efficiency.

    A new desiccant air conditioning system, MCMB : Mesh partitioned Countercurrent Moving Bed, is proposed to achieve an efficient dehumidification at low pressure drop. The dehumidifying section is divided into two flow channels by a wire mesh. Air is introduced from the bottom of one of the channels, while desiccant particles are flowed down in the other channel at a slow speed to achieve updraft type moving bed. Length of the acrylic dehumidifying section is 600 mm with a rectangular cross-section of 50 mm by 5 mm for air flow channel and 50 mm by 10 mm for particle flow channel. Axial distribution of air temperature, Tg, relative humidity, φ, and particle temperature, Tp, are measured and dehumidification rate is obtained. Based on these results, it is found that the MCMB actualizes the efficient isothermal dehumidification at low pressure drop. Furthermore, the wire mesh governs the mass transfer step when the particles have higher adsorption rates such as Zeolite.

    NiO redox processes and hydrogen production from dry and humidified methane were investigated by chemical looping combustion (CLC) and chemical looping reforming (CLR) using NiO as an oxygen carrier. To achieve a lower operating temperature in the NiO reduction process, oxide ion conductors such as gadolinia doped ceria (GDC) and strontium doped lanthanum aluminate (LSA) were investigated as the support materials of NiO. Hydrogen rich gas products were obtained by the CLC and CLR processes but a prolonged induction period for the NiO reduction by methane (i.e., induction period for CO2 formation from methane) was observed at relatively low operating temperatures in both processes. NiO/GDC and NiO/LSA lead to a decrease in the induction period of NiO reduction by comparison with the reference NiO/ZrO2. Upon repeating the NiO reduction-oxidation cycles, we also found that the induction period for NiO/GDC became shorter with an increase in the redox cycle number. However, for NiO/LSA this time became longer, which may result from the strong interaction between Ni and the support materials. This NiO reduction behavior on the oxide ion conductors is discussed together with the autocatalytic reaction mechanism for NiO reduction, which provides new insights into the efficient use of lattice oxygen in CLC and CLR.

    The flow behaviors in the downer of a large-scale triple-bed circulating fluidized bed (TBCFB) gasifier cold model, which is composed of a downer (Phi 0.1 m x 6.5 m), a bubbling fluidized bed (BFB, 0.75 x 0.27 x 3.4 m(3)), a riser (Phi 0.1 m x 16.6 m) and a gas-sealing bed (GSB, Phi 0.158 m x 5 m), were investigated. Sand particles with a density of 2600 kg/m(3) and an average particle size of 128 mu m were used as bed materials. Solids mass fluxes were in the range 113-524 kg/m(2) s. Average solids holdup in the developed region of the downer increased with increasing solids mass flux. The gas seal between the riser and the downer had a large effect on the solids holdup distribution in the downer. Compared with the solids holdup in the riser, a relatively low solids holdup was formed in the downer even at high solids loadings. A pressure balance model was set up to predict the solids mass flux for this TBCFB system. It was found that the static bed height in the GSB had a great effect on the solids mass flux. The possibilities of achieving a high density solids holdup in a downer were discussed. (C) 2011 Elsevier Ltd. All rights reserved.

    The catalytic performance of cermets made of 10% nickel or nickel oxide supported on YSZ (yttria-stabilized zirconia) for chemical looping combustion (CLC) and steam reforming (SR) of methane at 700 degrees C is investigated. Steam reforming of methane over the reduced catalyst resulted in a syngas containing more than 70% hydrogen and about 15% carbon monoxide. Chemical looping combustion of methane with insufficient lattice oxygen could potentially lead to 40-65% hydrogen rich gas products. Prolonged induction period (e.g. 30-80 min) in reduction of nickel oxide by methane has been observed in the presence of steam. The span of induction period increases by increasing steam partial pressure. It is hypothesized that the delayed reduction of nickel oxide is related to the retarding effect of steam on autocatalytic reactions of methane and hydrogen with lattice oxygen of nickel oxide and the subsequent reforming reactions.

    A novel large-scale triple-bed combined circulating fluidized bed (TBCFB), consisting of a riser (16.6 m in height, 0.10 m inner diameter), a downer (6.5 m in height, 0.10 m inner diameter) and a bubbling fluidized bed (BFB; 0.27 x 0.75 x 3.4 m(3)), was constructed as a cold model for a gasifier. The purpose of the new reactor design was to achieve a high solids mass flux which is required for exergy recuperative steam gasification of coal/biomass. In the TBCFB, a gas-sealing bed (GSB: 5.0 m in height, 0.158 m inner diameter) was installed between the BFB and the riser bottom to increase the pressure head to transport solids to the riser. The hydrodynamic behavior of silica sand particles (arithmetic mean diameter is 128 mu m) was investigated by independently controlling the flow rates of air in the riser, downer, BFB and GSB, and varying the bed heights of the BFB (H(BFB)) and GSB (H(GSB)) under ambient conditions. When the GSB gas velocity (U(gg)) was 0.10 m/s, the solids mass flux (G(5): kg/(m(2) s)) substantially increased with increase in riser gas velocity (U(gr)). The maximum G(s) obtained was 546 kg/(m(2) s) at U(gr)=12 m/s and H(GSB) = 4.6 m. This is due to the fact that the pressure head for transport of solids to the riser bottom increased sufficiently by increase in the GSB height. From the solids holdup (epsilon(s)) obtained from the apparent pressure difference, a dense phase (solids holdups: 0.070-0.095) was found to be formed at the bottom part of the riser (H(r)<= 5 m). The flow in the downer was developed in 1.5 m. The solids holdup in the developed area of the downer decreased from 0.0212 to 0.0128 as the downer gas velocity (U(gd)) increased from 0 to 1 m/s when G(s) was 406 kg/(m(2)s). (C) 2011 Elsevier B.V.

    Coal-fired Integrated Gasification Combined Cycle (IGCC) and Integrated coal Gasification Fuel-cell Combined cycle (IGFC) are being developed as high-efficiency electric power generation technology. However, the highest theoretical gross thermal efficiency of the conventional IGCC/IGFC is still below 52%. In order to obtain higher power generation efficiency, an advanced IGCC (A-IGCC) or advanced IGFC (A-IGFC) system making use of the exergy recuperation concept by recycling waste heat from gas turbine or fuel cells for steam gasification of coal and biomass was proposed in our laboratory. Corresponding to this system, a novel high-density triple-bed combined circulating fluidized bed (TBCFB) gasifier, composed of a downer pyrolyzer, a bubbling fluidized bed char gasifier, and a riser combustor, was proposed to replace traditional gasifiers such as the entrained flow bed gasifier. The new system is expected to more effectively utilize the waste heat from gas turbines or fuel cells and the heat produced by the combustion of the unreacted char in the riser combustor for pyrolysis and gasification of coal and biomass. In this short review, the advantages and future challenges in the development of high-density TBCFB gasifier are presented and discussed.

    Near-critical water gasification (NCWG) and steam reforming (SR) were investigated for the production of hydrogen from a biomass model compound (glucose) using fixed bed tubular reactor. Ruthenium/carbon and nickel/yttria stabilized zirconia (YSZ) were utilized to enhance the reaction rates of the two processes for NCWG and SR, respectively. NCWG experiments were performed at 200 bar and 360-450 degrees C, while SR experiments were conducted at 500-800 degrees C and atmospheric pressure. Although in both cases complete carbon gasification is achieved, gas composition, hydrogen selectivity and overall energy efficiency show strong dependencies on the type of process itself and the associated operating conditions. It is shown that operating the reforming reaction of glucose at high pressures and low temperatures (NCWG) results in a significant amount of methane and trace amounts of carbon monoxide. In contrast, gasification of glucose at atmospheric pressures and high temperatures (SR) leads to a methane-free gas stream that contains few percents of carbon monoxide. Considering energy recovery and neglecting the heat losses, the maximum cold gas efficiency of the NCWG and SR reached 78% and 91%, respectively. The features of the two catalytic reaction processes are discussed in terms of the experiments and process simulations. (C) 2010 Professor T. Nejat Veziroglu. Published by Elsevier Ltd.

    Conventional air conditioning consumes huge amount of energy to remove latent heat during hot and humid summer in Japan. Desiccant air conditioning is able to remove moisture directly and the system is able to utilize waste heat for drying of the desiccant, thus, low temperature heat is applicable to the separation process. Counter current flow as well as parallel current flow is applied for air-desiccant contact system to improve applicability of waste heat and rate of moisture separation. Their performance are confirmed by the simulation based on the fundamental experiment to determine the mass transfer coefficient and continuous dehumidification.

    Low temperature pyrolysis and gasification has been investigated based on the chemical looping combustion (CLC), where insufficient amount of lattice oxygen was reacted with hydrocarbons. Metal oxides such as nickel oxide, iron oxide and titanium oxide were used as lattice oxygen source and were coated on silica gel or porous aluminum. Single column reactor was used for experiments and 36.1 mmol of polyethylene was dropped to the column whose temperature was ranged from 693 to 1073 K. For the pyrolysis, hydrogen yield was 100% of polyethylene contained hydrogen, while methane, CO and CO(2) were minor products and almost half of the supplied carbon was deposited on the particle surface. On the other hand, for the steam gasification, 2-3 mol of the hydrogen was generated from 1 mol of carbon and almost no carbon deposition was observed. It is found that no wax and heavy tar was observed in the exhaust. Therefore, the lattice oxygen was able to be applied to the low temperature gasification of hydrocarbons. (C) 2009 Elsevier Ltd.

    A laboratory scale pressurized fluidized bed combustion (PFBC) system was designed and constructed to clear the details of combustion of coal in PFBC. This PFBC system allows visual observation of hot fluidized bed by using a transparent electric furnace. To simulate the emission characteristics of coal combustion of the full scale PFBCs by this lab-scale PFBC, a new similarity rule was introduced. Volumetric heat input and mean gas residence time through fluidized bed in lab-scale PFBC were adjusted to the values matching those of full scale PFBCs. Motion of bubbles and burning of coal particles and volatiles were recognized by visual observations. Volatiles burned mostly in the bottom region of the fluidized bed. On the other hand, char particles burned uniformly in the bed. Ranges of conversion of fuel-N to NO agreed with those obtained in a full scale PFBC. Thus, it is verified that new similarity rule explained above is useful to simulate the combustion behaviors in full scale PFBC by a laboratory scale small PFBC. Effects of operating pressure and O_2 partial pressure in flue gas on NO emission were examined. Linear relationship between O_2 partial pressure and NO emission was observed. NO emission was decreased rapidly with increasing in operating pressure at constant O_2 partial pressure. This may be caused by an enhancement of NO reduction by char particles because of increase in number density of char particle in the bed at elevated pressure. In order to confirm this assumption, initial combustion rate of char in the pressurized fluidized bed condition was measured. Initial combustion rate of char increased with 0.6th power of operating pressure. This means that char number density is increased in elevated pressure condition. One of the major reasons to achieve the low NO_x emission in PFBC condition, should be the reduction of NO_x by char particles through the bed.

    A circulating fluidized bed (CFB) system of photocatalyst is studied toward successive treatment of large amount of gas such as tunnel exhaust. The experimental system is 2 m high. A riser of the CFB is concentric double-pipe structure. A light source is installed inside the inner pipe. Silica gel powder coated with titanium dioxide by the sol-gel method provides composite particles of the photocatalyst. Average size of composites is 203 mu m. Composite particles are fluidized and carried upward in the annulus area sandwiched between the inner and outer pipes.
    An endurance test of a photocatalyst composite is carried out for attrition using the CFB for long time operation. An observation by SEW EDX revealed that a part of photocatalysts on the surface of the composites falls off at the initial stage of the solid circulation and others adhere to the composites tightly. In addition, the photocatalytic removal of NOx is also studied by measuring NO and NO2 concentration. The NO, removal efficiency depends on the solids volume fraction of photocatalyst composites in the riser of the CFB. The mechanism of the NO, removal by the photocatalyst composite in the CFB is thought to be divided into oxidation and adsorption processes. The adsorption process is regarded as more important than the oxidation processes in this experimental system. (c) 2004 Elsevier B.V. All rights reserved.

    Hydrocarbon can be gasified with steam into fuel gas, including CO, CO 2, H2, CH4, etc. For H2 production, it is necessary to separate the other gases from hydrogen. In this study, hydrogen production by removal of carbon oxides during hydrocarbon gasification with CaO and other metal oxides was examined theoretically and experimentally. It was experimentally confirmed that when the hydrocarbon, water, and Ca(OH)2 were set in a micro-autoclave at a temperature of 973 K and a pressure of 25 MPa, the only gas products were hydrogen along with a small amount of methane. CO was converted to CO2, and CO2 was absorbed by Ca(OH)2 to form CaCO3 completely. CaOSiO 2 can absorb CO2 to form CaCO3 under the same experimental conditions. Others such as MgO, SnO, and Fe2O 3 were found to be unsuitable sorbents for CO2 absorption in the gasifier at high temperature. By calcination, CaCO3 can reform to CaO. Because the chemical energy contained in CaO can be released during hydrocarbon gasification, H2 production efficiency as high as 70-80% can be expected. © 2004 Elsevier Ltd. All rights reserved.

    In H-2 production from woody biomass by steam gasification using CaO as a CO2 sorbent, the effect of reaction parameters such as the molar ratio of CaO to carbon in the woody biomass ([Ca]/[C]), reaction pressure, and reaction temperature was investigated on H-2 yield and conversion to gas. In the absence of CaO, the product gas contained CO2. On the other hand, in the presence of CaO ([Ca]/[C] = 1, 2, and 4), no CO2 was detected in the product gas. At a (Ca]/[C] of 2, the maximum yield of H was obtained. The H2 yield and conversion to gas were largely dependent on the reaction pressure, and exhibited the maximum value at 0.6 MPa. It is noteworthy that H-2 was obtained from woody biomass at a much lower pressure compared to other carbonaceous materials such as coal (> 12 MPa) and heavy oil (> 4.2 MPa) in steam gasification using a CO2 sorbent. H-2 yield increased with increasing reaction temperature. Woody biomass is the one of the most appropriate carbonaceous materials in H-2 production by steam gasification using CaO as a CO2 sorbent, taking the reaction pressure into account.

    Nanoparticle fluidization was studied in a centrifugal fluidized bed (CenFB) with variable gravitational acceleration (Gg) conditions. Agglomerate size variation in CenFB nanoparticles (7 nm) was examined with G and fluidization time. With increasing fluidization time, the agglomerate size was found to decrease and reach an equilibrium value after several hours. Higher G reduced agglomerate size. To elucidate these phenomena, a comprehensive model was developed based on the energy balance model with respect to energy consumption for disintegration of agglomerates. Experimental results showed good agreement with the proposed model. Effects of high G on agglomerate fluidization are clarified as follows. The critical minimum size of agglomerates, which is the agglomerate size estimated by the force balance model, is reduced by high G. Attainable energy for disintegration of agglomerates is increased, leading to decreased agglomerate size. (C) 2004 American Institute of Chemical Engineers.

    "HyPr-RING" is a new H-2 production process using carbonaceous fuels in which the fuel is reacted with subcritical steam and a calcium-based CO2 sorbent. We investigated the applicability of this process to organic matter by examining the performance of the process with fuels of differing volatility. The gasification rate and relative contributions of the volatile and "char" components to H, production were investigated by using dried sewage sludge with a high volatile component concentration, coal with an intermediate volatile component concentration, and coal char with a low volatile component concentration. During the initial thermal decomposition, carbon in the fuels rapidly decreased with time and was converted to carbonaceous gas of CH4 and C2H6 in addition to H-2. The amount of the decrease depended on the volatile content in the fuels. Following this initial rapid stage, the residual carbon appeared to become charlike, even for the high volatile content fuel. The gasification rate became slow, and the gasification shifted to favor H-2 production in a molar ratio of H-2 to CH4 that approximated the equilibrium composition for a char and steam reaction. NaOH catalytically promoted H-2 production even for the sludge.

A newly designed drop tube reactor was introduced in order to achieve a rapid increase in sample temperature to simulate the initial stage of continuous reaction. Hydrogen generation was accelerated effectively with an addition of calcium hydroxide as a carbon dioxide absorbent, with efficiency of calcium utilization becoming higher under the higher pressure condition. Methane generation at the initial reaction step was suppressed by the addition of calcium to the drop tube reactor, while much methane was obtained in an autoclave-type reactor whose rate of temperature increase was small.

    Coal/CaO powder mixtures were continuously supplied into a reactor to react with steam at high pressure and high temperature. At 923 K and 5.0 MPa, the gas produced from the reaction of Taiheiyo coal/CaO with steam consisted of mainly H-2, with smaller amounts of CH4, C2H4, C2H6 and CO2. Increasing the pressure enhanced H-2 production and CH4 decomposition. Above 3 MPa, the gas from the reaction contained <3% CO and CO, Under high pressure, CaO reacted with steam to form Ca(OH)(2) which absorbed CO2. The H-2/CH4 ratio in the product gases from three different rank coals Datong coal (bituminous), Taiheiyo coal (sub-bituminous), Wyoming coal (lignite) followed the order Datong > Taiheiyo > Wyoming. The Wyoming and Datong coals produced less H-2 than the Taiheiyo coal. (C) 2003 Elsevier Ltd. All rights reserved.

    Efficient NOx removal from a large volume of exhaust gas with high NOx concentration was investigated using a fluidized bed system with a fine photocatalyst. An ultrafine photocatalyst was coated on carrier particles for easy handling in the fluidized bed process. Two types of fluidized beds were tested for NOx removal; a Bubbling bed of 35 mm inner diameter, and a circulating fluidized bed of 18 mm I.D. with 1140 mm riser height. Simulation was also carried out to clarify the effect of the size of the experimental setup and flow characteristics. The fluidized bed system with a photocatalyst was able to remove NOx continuously from a large volume amount of exhaust gas. The dominant parameters were mass transfer from the main gas stream to the catalyst surface, solid loading rate and maximum capturing capacity of NOx.

    Pulverized Taiheiyo coal (Japanese subbituminous coal) was gasified with steam in the presence of CO2 sorbent (Ca(OH)(2)) under relatively high pressure (approximately 20 MPa; subcritical condition) using a tubing-bomb microreactor (TB reactor). The transient characteristics in the conversion of coal and the formation of gaseous products during the gasification were investigated. During initial heating period, 40-50 wt.% of the coal initially loaded was rapidly converted to gas or tar. In the presence of Ca(OH)(2), the yield of gaseous products was apparently increased owing to the catalytic effects of Ca(OH)(2) on coal gasification. No CO2 was observed in the produced gas at any soaking time in the gasification with Ca(OH)(2), suggesting that CO2 sorption by Ca(OH)(2) took place effectively under high-pressure conditions. A rigid agglomeration of char and CO2 sorbent was observed at relatively high temperature, which is attributed to the formation of melts of the CO2 sorbent. (C) 2003 Elsevier Science B.V.

    A new hydrogen production method, the HyPr-RING process was applied to a vacuum residue of Arabian light crude oil to clarify the effects of added water, calcium hydroxide, which absorbs carbon dioxide, and the reaction temperature. It was determined that when a sufficient amount of calcium hydroxide was present, it provided enough water to produce hydrogen and additional water was not necessary. To consume all of the carbon dioxide in 1 mol of carbon from the feedstock, 25 mol% of calcium hydroxide was needed and hydrogen production was saturated at 50 mol%. Carbon conversion was dependent mainly on the temperature and was slightly dependent on water and pressure. The reaction pressure was as low as 4.2 MPa. Thermal decomposition of the feedstock was the dominant reaction below 600 degreesC, which produced methane. (C) 2002 Elsevier Science Ltd. All rights reserved.

    Hydrogen generation during the reaction of a coal/CaO mixture with high pressure steam was investigated using a flow-type reactor. Coal, CaO and CO reactions with steam, and CO2 absorption by Ca(OH)2 or CaO occurred simultaneously in the experiment. It was found that H-2 was the primary resultant gas, comprising about 85% of the reaction products. CO2 was fixed into CaC03 and CO was completely converted to H2. Pyrolysis of the coal/CaO mixture carried out in N-2 was also examined. The pyrolysis gases were compared with gases produced by general coal pyrolysis. While general coal pyrolysis produced about 14.7% H-2, 50.5% CH4, 12.0% CO and 12.0% CO2, the gases produced from coal/CaO mixture pyrolysis were 84.8% H-2, 9.6% CH4, 1.6% CO2 and 1.1% CO.

    H-2 production from organic wastes and metal wastes by absorbing CO2 during pyrolysis and gasification (HyPr-RING method) was studied experimentally. Experiments were performed by using an autoclave at 973 K and 25 MPa.
    From organic wastes, such as wood, salad oil, styrene foam, PET bottles, black rubber, benzene, graphite, sewage sludge and polyvinyl chloride, it was found that H-2 was the major product gas, while the remainder was CH4. CO2 was completely absorbed by the sorbent of Ca(OH)(2). CO was not detected in the product gas. These wastes had high conversion to gas phase, except styrene form, benzene and graphite.
    Only 40 ppm NH3 was detected in the product gas of the sewage sludge. Others harmful gases, such as NOx, HCN, H2S and HCl were not detected in the product gases of sewage sludge and polyvinyl chloride.
    Powders of Al and Fe could be completely converted to H-2 by reaction with H2O. However, with increasing sample size, the conversion of Fe fell rapidly.
    H-2 production from mixtures of organic and metal wastes was also confirmed by experiment.

    A new innovative hydrogen-production method, HyPr-RING (hydrogen production by reaction-integrated novel gasification), using hydrocarbon and water has been proposed. Experimental results show that, using one reactor, I mol of carbon generates 2 mol of hydrogen with no pollutants and no carbon oxides being detected in the product gas phase. Water reduction by the hydrocarbons and the CO2 absorption reaction are the key reactions in this method. The absorption of CO2 from the gas phase improves the yield of hydrogen production from water.
    A feasible hydrogen production process was designed by applying the above-mentioned method, and the thermodynamic efficiency was calculated accordingly. Theoretically, the calculated cold-gas efficiency of this process exceeds 90%, and no clean-up system is required. This process potentially reduces hydrogen production costs compared to conventional hydrogen production methods. (C) 2002 Published by Elsevier Science Ltd.

    Char combustion rate in elevated pressure conditions was examined experimentally and theoretically by changing factors such as particle size, gas flow rate, and oxygen concentration. These factors were found to influence rate control regimes and change the pattern of pressure effect on rate. For instance, at same temperature, decrease in the particle size of char enhanced the effect of pressure on char combustion rate.
    Mass flow rate, ug rhog, or flow rate at standard temperature and pressure, u(g,o) was used to evaluate the diffusion resistance of the gas film. It was found that, char combustion rate increase with increasing ug rhog or u(g,o).
    Combustion rate can be expressed by using the oxygen concentration at standard temperature and pressure, C-o, or the partial pressure of oxygen, P-o2, as the gas reactant term in the rate equation. However, explanation of pressure effect on combustion rate was greatly different in both expressions.

    The fluidized bed of ultrafine particle of photocatalyst is applied to treat nitrogen oxides (NOx) by photocatalytic oxidation. Three different TiO2 particles with primary particle diameters of 7, 20 and 200 nm are used as the bed material. The removal of NOx using a two-dimensional fluidized bed of ultrafine TiO2 particles is investigated. The fluidized bed of 7 nm TiO2 exhibits high removal efficiency of NOx because of its large specific surface area. It is found that the amount of NOx removal is proportional to the specific surface area. The fluidization of three kinds of photocatalysts shows the following characteristics. Agglomerates of 7 and 20 nm particles appear to be so hard that they are not destroyed during fluidization because of large adhesion forces of particles. In the case of 7 and 20 nm particle systems, the bed height is found to increase progressively with the increase in gas velocity, while the bed expansion is observed to level off for 200 nm particle system. The entrainment rate of 7 and 20 nm particle systems is found to be smaller than that of 200 nm particle system. (C) 2001 Elsevier Science B.V. Ah rights reserved.

    A new hydrogen production process, named the HyPr-RING, has been proposed. Fundamental concept of the HyPr-RING is integration of water carbon reaction, water-gas shift reaction and CO2 absorbing reaction in a single reactor. Firstly, thermodynamic analysis was done to judge the possibility to realize the process. it was found that high pressure and temperature condition, such as 20 MPa and 1000 K is required to promote this integrated reaction.
    Next, experimental verification of the new process was done under the high pressure and temperature reaction conditions. As the results, integration of above three reactions in a single reactor can be done successfully and produced a large amount of hydrogen as estimated by thermodynamic analysis. Experiments showed that organic materials including coal, heavy oil, biomass, plastics can he used in this process. In the gaseous phase, no pollutants such as H2S, SO2, COS are detected so that gas cleanup system is not required for power generation when this process is used.
    Finally, a process design was made to estimate process efficiency. Theoretically, 1 mole of carbon can generate 2 moles of hydrogen and cold gas efficiency of this process estimated as more than 80 per cent. The process potentially reduces hydrogen production cost compared with the conventional hydrogen production methods.

    Char combustion is investigated in the temperature range of 559-1273 K and pressure range of 0.1-1.6 MPa in a 0.5th-order reaction (a lignite coal char) and a first-order reaction (a bituminous coat char).
    The intrinsic combustion constant k(v) and the reaction order n do not vary with pressure, but the char combustion initial rate varies with the pressure in the chemical kinetics control and the internal diffusion influence regimes. The variation of initial rate with pressure was also sensitized to the reaction order n. In the chemical kinetics control regime, the char combustion initial rate was proportional to P-n with the exponent n, the reaction order. In the internal diffusion influence regime, the apparent dependency of char combustion initial rate on pressure changed with the exponent range from n to n/2, The reaction initial rate in the external diffusion control regime was invariant with pressure. A rate expression was developed for predicting the initial rate of nth-order char combustion under elevated pressure.

    A new simple algorithm is proposed for simultaneous measurement of the velocity and the trajectory of solid particles in unsteady gas-solid flow It utilizes the time difference of the particle peaks between the twin and reference signals obtained using a reflective optical fiber probe to calculate the particle velocity. The critical step in the algorithm is to determine the corresponding peaks for the identical particles; the closest peaks in the pair of signals are selected This algorithm is applied for relatively low concentration of particles where the distance between particles is greater than twice the distance between the main and reference optical fibers.
    The accuracy of the proposed algorithm is confirmed using a free-fall particle system. The particle velocity in a circulating fluidized bed (CFB) is also examined. The results show that this method can be used to continuous measurement the particle velocity and direction.

    A circulating fluidized bed with a riser of 0. IO-nz inner diameter and 5.5-m height is used to study the flow, structure of solid particles in the CFB riser. The solids circulation rate is fixed at 45.6 kg/m(2)s, the superficial gas velocity is varied between 2.03 and 2.42 m/s to obtain an S-shaped and uniform distributions of particle concentration in the axial direction, respectively Flow of fine particles (FCC; d(p)=54 mu m) is visualized through a penetrative-type particle image scope (PPIS, 3 mm in diameter) with a high-speed video system, Visualization is performed in the fast fluidization and dilute transport regimes. All images are recorded at 4000 frames/s by dividing the full frame into four subframes. Dense particle swarms are observed in both the dense and dilute flow conditions. Typical particle swarms are analyzed to have thickness or diameter ranging from a. I mm to 2 mm and solids holdup exceeding at least 0.25 and possibly reaching that in a loosely packed condition. The velocities of individual particles and particle swarms are determined from the recorded images. While most of the individual particles have slower ascending velocities than the superficial gas velocity, the rising velocity of the particle swarms is found to be often higher than the superficial gas velocity. The frequency of the partcle swarms in the dense flow condition is higher than that in the dense flow condition.

    A new-concept gas-solid combustion system "MERIT" is proposed to contribute the settlement of environmental problems. This system divides combustion into two reactions, oxidation of metal by air at high temperature and reduction of metal oxide by fuel at low temperature. It recirculates the metal as an oxygen-carrier between these two processes. Since the low-temperature heat absorbed in the reduction reaction is released as the high-temperature heat in the oxidation reaction, the overall thermal efficiency is improved. There is no NOx emission because the oxidation is a gas-solid reaction between metal and air without a flame. Since the reduction reaction produces only carbon dioxide and water vapor, CO2 can be easily separated and collected by cooling the exhaust gas. The key point of the development of this combustion system is the kinetics of oxidation and reduction reactions. We carried out experiments to clarify the fundamental kinetics of the two reactions applying nickel as metal and methane as a fuel. It was certified that the rates of both reactions were fast enough. This result revealed that this combustion system has high potential to achieve high thermal efficiency and contribute to the settlement of environmental problems.

    Motion of glass beads of 0.4 mm mean diameter is observed in the central region of a circulating fluidized-bed (CFB) riser by coupling a reflective-type particle image scope (RPIS) with a highspeed video system of 3000 frames s(-1) recording rate. Transient changes in the particle velocity are measured under both dilute and dense conditions. The observed speed of ascending particles ranges from 0 to 3.0 m s(-1) at a superficial gas velocity of 6.0 m s(-1). Descending particles are also observed, and their speed ranges from 0 to 1.6 m s(-1) The structure and motion of particle swarms are analyzed with a special emphasis on particle collision. It is confirmed that the speed, moving direction, and packed density of the particle swarms are subjected to persistent time variations. Various patterns of particle motions are identified in the CFB riser, induced by a diversity of collision mechanisms. These include momentum transfer from a colliding particle to other particles being contacted, grazing followed by particle rotation, roundabout motion of a particle around another, simultaneous collision involving more than three particles, and successive particle collisions.

    A monolayer-particle fluidized bed is constructed to elucidate the behavior of particles. By using a high-speed video camera, observation and recording of the movement of particles, especially around bubbles were performed. The pictures were saved as data files in a personal computer by applying an image analyzer.
    Data files consist of 470 x 370 pixels having 256 grades of brightness for each pixel. Then a program that recognizes each individual particle and searches for its loci from the consequential data files is made by tracing pixels with brightness higher than a certain threshold value. Also, a program for calculating the velocity of each particle is developed. In this program, each picture is divided into 100 blocks and a typical velocity of the particles in the block is calculated by comparing it with that in the next picture. By this typical velocity of the block, each particle can find the position in the next picture. In this manner, the velocity of each particle can be calculated.
    The characteristic feature of this system is to be able to trace all the particles continuously without any tracer particle. The applicability of this system to trace the complex behavior of particles around a bubble confirms its effectiveness.

The hollow fiber is wound In a plane spiral form, each of which can be piled in a cylindrical module. A bubble column is used in the presence as well as absence of a draft tube, which the module can fit to and serve. as part of. To enhance the effectiveness in the module's generating fine bubbles, electrolytes are added to the liquid phase, water. Over a superficial gas velocity range of 0.1-2 mm/s, the hollow-fiber module (in comparison to conventional perforated-plate distributors) demonstrates, even with moderate gas-supply pressures (<0.3. MPa), as high as 3-fold and 20-fold increases in the volumetric mass transfer coefficient in the absence and presence of the electrolytes, respectively. The former has been attained with a negligible increase in the gas holdup; the latter has accompanied a large (similar to 20-fold) increase in the gas holdup. While in the latter case the bubbles are very finely dispersed, the draft-tube mode of operation secures still reasonable liquid circulation with nonclustering, spherical bubbles uniformly dispersed in each of the core and annular regions of the bubble column.

    A particle image scope consisting of an image fiber and a video system was developed to perform microscope observations of solid particles in circulating fluidized beds (diameters of risers: 60 mm and 100 mm; height: 4500 mm and 5500 mm, respectively). The behavior was examined using coarse sand particles (d(p) = 0.30 mm, U(mf) = 0.10 m s-1) and fine sand particles (d(p) = 0.057 mm, U(mf) = 0.002 m s-1). The images obtained clearly showed the shape and the number of the solid particles. The particle velocity was also determined by adjusting the exposure time of the 35 mm camera or video camera. Therefore, the variation of the solid holdup as a function of time, or the particle velocity, was easily obtained. ne results show that the particle image scope developed here is quite effective in the microscope observation of gas-solid flow.

    A simultaneous and continuous measuring method for the gas bubbles and solid particles is developed by introducing high-shutter speed video cameras with 1/2000s exposure time and an image analysis system. The image analysis system includes a color special-effects generator, with which the images from each of two video cameras can be superimposed, and a video disk recorder which can digitize and store 1200 images successively.
    The system was inspected by using a single-layer two-dimensional fluidized bed. Both the dilute portion around gas bubbles and the trajectories of tracer particles are clearly observed. As a result, it can be said that the video system introduced to this work is quite effective for both macroscopic and microscopic investigation of the gas-solid fluidized bed.

    Spatiotemporal measurements of bubble properties in a three-dimensional free-bubbling fluidized bed were done by using double-line arrays of reflective optical fiber probes and a microcomputer-aided data processing system. The measuring system could get real bubble shapes and the bimodal lateral distribution of the bubble frequency and holdup. The aspect ratio D’B/DB to express the extent of bubble deformation was correlated with the coalescence index defined by (U0 - Umf)/UB. In the case of two vertically aligned bubbles which were going to coalesce, the average aspect ratio of the leading bubble was almost constant, while that of the following bubble increased sharply with coalescence index. By plotting the bubble rising velocity UBagainst the real bubble diameter DB, three kinds of bubbles, viz., spherical cap, elongated and slug, could be distinguished. On the other hand, by plotting it against the bubble height D’B, the data for these three kinds of bubbles crowded around a line of KB-0.9, showing that the three kinds of bubbles in real situations cannot be distinguished by such plot. © 1986, The Society of Chemical Engineers, Japan.

    The chemical looping reaction is applied to the combustion and gasification of coal for effective energy conversion. The reduction of metal oxide is examined in the fixed/fluidized bed of 20 mm I.D. and 1120 mm high. As a lattice oxygen carrier, iron oxide is used and coated on the porous alumina of 0.2 mm mean diameter. Taiheiyo coal of 0.5 g is dropped into the test section and gas production profiles were measured with the temperature range 793 K through 983 K. Initial stage of the reaction, only carbon dioxide is observed, while the hydrogen is produced simultaneously for the insufficient amount of lattice oxygen. Hydrogen yield is about 2.5 times of the carbon content and this exceeds 2.0 which is obtained from the complete reactions of the Water gas and Shift reactions. The extra hydrogen is produced from the hydrogen contained in coal and it may give higher cold gas efficiency.

    Language:Japanese   Publisher:The Japan Society of Mechanical Engineers  

    The Chemical Looping Combustion/Gasification Systems, CLC/CLG, are one of the possible counter measures for the separation and withdrawal of carbon dioxide from the combustion systems. Because much carbon dioxide is emitted in the coal utilization, CLC/CLG are expected to be applied to the coal combustion. Then, high reactivity and low cost lattice oxygen carrier will be required in the CLC for coal. The ash separated from the system may accompany the lattice oxygen carrier and the development of low cost carrier becomes important. In this study, waste metal oxide is used to achieve low cost lattice oxygen carrier and it is found that waste metal oxide easily form agglomerate. Metal oxides are deposited on the inert particles to avoid agglomeration.

    A project for developing a hydrogen production process, HyPr-RING (Hydrogen Production by Reaction Integrated Novel Gasification), started in 2000. This process is expected to have a higher cold gas efficiency as 75% for hydrogen production from coal with CO_2 recovery. The exothermic and the endothermic, and the gas production and the gas separation reactions are integrated in one gasifier, to produce hydrogen by one step without oxygen injection. Absorption of CO_2 by CaO (lime) to enhance CO shift reaction and consequently to raise the hydrogen concentration, is a key reaction in the reaction system. During passed years, thermodynamic and experimental studies were performed for understanding what happens in the gasifier when the reactions are integrated, and for finding suitable sorbents and conditions for capturing CO_2 and producing higher concentration hydrogen. We had built a continuous experiment reactor system containing feeding, solid-gas contacting, heating, pressure charge and gas-solid separation. It was found that H_2 was majour product gas with few CH_4. CO was completely shifted to H_2 and CO_2, and most of CO_2 and H_2S were fixed by lime sorbent.

    The optical fiber probe technique has been widely used in the analysis of gas-solid fluidized bed phenomena owing to the small size, quick response and flexibility of the probe as well as wide ranges of applicability of the technique as a whole. With potentially equal applicability to gas-liquid and gas-liquid-solid flow systems, this technique has recently witnessed its important role in the multiphase flow research. No systematic, fundamental explanations/guidelines for the usage of the fiber optics, however, are available to our knowledge in the pertaining research field. In this article, we introduce the basic probestructures, characteristics of the obtained signals, the data processing techniques and the range of applicability to further encourage the use of optical fiber techniques "tailored" to the multiphase flow analysis.

    A single-layer gas-solid fluidized bed is developed by setting two glass plates vertically with a spacing space of which is slightly greater than the diameter of the particles. The behavior of gas bubbles is observed in detail by introducing high shutter-speed video cameras with 1/2000 s exposure time and an image analyzer.
    It is found that the rising velocity of bubbles in the single-layer fluidized bed is almost the same as that in the ordinary two-dimensional fluidized bed. The effect of gas velocity and height from the distributor on bubble growth is almost the same as in the three-dimensional fluidized bed despite its extremely small bed width.

    Language:Japanese   Presentation type:Poster presentation  

    Chemical looping processes require low cost and higher reactive lattice oxygen carrier, especially for heavy hydrocarbon materials such as coal, biomass and so on. They contain ash and catalytic poison which deactivates lattice oxygen carrier. Spray drying granulation was applied to granulate various kind of particles to support the lattice oxygen carrier. Simultaneous spray drying granulation and post composite method were tested by changing the granulation conditions to reduce the amount of oxygen carriers. Furthermore, various factors were discussed affecting on the reactivity and strength of the granulated particles. Conclusive remarks are as follows. With increasing the calcination temperature, the strength of the granulated particles was increased. However, the specific surface area of them was decreased gradually. On the other hand, the reactivity of them kept almost constant regardless of the decrease of the specific surface area. It was thought that the distribution of the lattice oxygen carrier and voidage in the granulated particles were important.

    Various technologies have been conducting to solve the global warming problem. Reduction of humidity in the air is one of the key technologies for the effective energy conservation. A new desiccant air conditioning system using a circulating fluidized bed is proposed as a promising technology and clarified the characteristics of dehumidification using a small experimental apparatus. In addition, the estimation of the system scale is discussed using a developed model to produce the large quantity of low dew point air.|rn||rn|According to the experimental results, the proposed system is superior to the conventional rotor system from the viewpoint of pressure drop and dehumidification ability. Therefore, the proposed system can be applied to the energy conservative air conditioner and has the possibility to apply the large quantity of low dew point air.|rn||rn|Optional experimental study has been conducted to confirm the desorption performance of desiccant particles in a bubbling fluidized bed. Long time operation is enough to make particles for producing the low dew point air. It is clear that the decreasing the water content in the particles makes the air humidity lower regardless o
