  • Hydrogen production via steam-iron reaction using iron oxide modified with very small amounts of palladium and zirconia

    APPLIED CATALYSIS A-GENERAL   288 ( 1-2 ) 143 - 148  2005年07月

    　概要を見る

    We investigated hydrogen production by the steam-iron reaction using iron oxide modified with very small amounts of palladium and/or zirconia at a temperature of 723 K and under atmospheric pressure. Reduction of iron oxide with hydrogen and oxidation of partially reduced iron oxide with steam (Fe3O4 + 4H(2) <-> 3Fe + 4H(2)O) were repeated in the range of reduction degree of 30-50 mol%. Changes in the weight of the samples were monitored using a tapered element oscillating microbalance (TEOM) to control the degree of reduction. Unmodified iron oxide caused significant deactivation due to sintering with increasing number of redox cycles. The addition of a very small amount (0.23 mol%) of palladium or zirconia onto the surface of the iron oxide enhanced the reduction and/or oxidation of the partially reduced iron oxide, which suppressed sintering. Palladium accelerated both the reduction and oxidation rates of partially reduced iron oxide, while zirconia increased only the oxidation rate. Addition of both palladium and zirconia together to the iron oxide resulted in marked enhancement of both reduction and oxidation. (c) 2005 Elsevier B.V. All rights reserved.

    Disk-type SrFeCo0.50Ox, asymmetric membranes were prepared for high-temperature oxygen separation using both a previously reported solid state technique in which ethyl cellulose is introduced and then removed by calcination to produce a porous support layer and a modified technique in which carbon fiber is added to the ethyl cellulose. The oxygen permeabilities of the resulting SrFeCo0.50Ox asymmetric membranes were measured at 973-1173 K. The addition of carbon fiber to ethyl cellulose resulted in the improvement of gas diffusivity in the porous support layer, which increased the flux of oxygen through the modified asymmetric membrane.

  • Catalytic activities and coking resistance of Ni/perovskites in steam reforming of methane

    APPLIED CATALYSIS A-GENERAL   286 ( 1 ) 23 - 29  2005年05月

    　概要を見る

    Steam reforming of methane for the purpose of hydrogen production was performed using nickel catalysts supported on a variety of perovskites, including LaAlO3, LaFeO3, SrTiO3, BaTiO3, La0.4Ba0.6Co0.2Fe0.8O3-delta, to compare the catalytic activity and resistance to coking of these catalysts to those of the conventional Ni/alpha-Al2O3 catalyst. Ni/LaAlO3 and Ni/SrTiO3 showed high catalytic activities among the Ni/perovskites and longer-term stabilities than the conventional catalyst. Temperature programmed oxidation of carbon deposited on used catalysts revealed that inactive carbon species detected on Ni/alpha-Al2O3 were not formed in the case of Ni/LaAlO3. The results of temperature programmed reduction confirmed that consumption and recovery of the lattice oxygen in perovskites occurred during the reaction, and that the reducibility of perovskites had a great impact on the steam reforming activity. The lattice oxygen in perovskites is considered to play important roles in promoting the oxidation of CH, fragments adsorbed on metallic nickel. (c) 2005 Published by Elsevier B.V.

    　概要を見る

    The undesired structural change of mordenite with Si/Al-2 = 15 during the ion exchange and during calcination from the sodium form into proton form, especially the dealumination after the calcination, was studied. The Si-29 NMR results clarified that calcination of the NH4-form mordenite with Si/Al-2 = 15 at > ca. 800 K, followed by the contact of proton-form sample with the atmosphere containing humidity, induced the dealumination. However, the samples carefully kept free from humidity after the heat treatment showed no dealumination or only a low degree of it. The Al-27 NMR and ammonia TPD results agreed with these findings. The origin of dealumination is thus considered to be the contact of the proton-form sample with humidity after the calcination. On the other hand, the dealumination was not observed after calcination at < 673 K. The H-1 NMR indicated that the ca. 1/3 of the ion-exchange sites were blocked by the ammonium cations after calcination at 673 K, suggesting that the dealumination was prevented by the ammonium cations. On the basis of these findings, a standard set of conditions in which one can safely prepare the proton-form zeolite with high quality is proposed. The recommended temperature for the ion exchange is room temperature, because it is high enough to exchange the ions in this case. The most important variable is the calcination temperature; it should be lower than 673 K in order to avoid the dealumination. These conditions were confirmed to yield zeolites with a high framework aluminum content and ordinary catalytic performance. (c) 2005 Elsevier B.V. All rights reserved.

    　概要を見る

    A joint study was organized to establish a standard set of conditions for the ion exchange of zeolite from sodium into proton-form. The sodium-form mordenite with Si/Al-2 = ca. 15 was ion exchanged into an NH4-form, followed by calcination according to various recipes. Then various advanced techniques for characterization (ICP, TG, XPS, SEM, XRD, N-2 adsorption Si-29 and Al-27 NMR, benzene diffusion, IR of OH and adsorbed pyridine and CO, ammonia TPD) were applied. and some test reactions (cracking of cumene, isopropylation of biphenyl, oligomerization of propene and chichibabin condensation of acetaldehyde and ammonia into picoline) were conducted. The ion exchange (removal of sodium) proceeded as expected, but remarkable differences were observed in physicochemical and catalytic properties of the thus-prepared proton-form samples. Exceptionally high temperature (383 K) for the ion exchange resulted in the structural degradation, while most samples exchanged at 333-353 K maintained the crystallinity and pore volume. The use of NH4Cl slightly changed the crystal morphology. Extra-framework aluminum species was formed on most samples after calcination above 773 K. In contrast, calcination at 673 K maintained the framework aluminum. Therefore, the dealumination is considered to proceed after complete removal of ammonia from the ammonium-form zeolite. However, the proton-form zeolite was stable under dry conditions, so it is speculated that the dealumination was induced by the contact of the proton-form zeolite to atmosphere with humidity. The total and Bronsted acidity decreased with the dealumination, while Lewis acidity increased. On the other hand, rapid heating of the ammonium type zeolite caused narrowing of the micropores. These structural changes seriously affected the catalytic activities for various reactions. (c) 2005 Elsevier B.V. All rights reserved.

    　概要を見る

    MCM-41-type mesoporous materials possessing strong Bronsted acidity originated from ZSM-5 zeolite were synthesized by using soluble aluminosilicate species containing the fragments of the structure of ZSM-5 zeolite. The thermal stability of the mesoporous structure of the obtained mesoporous material was enhanced by the post-treatment with an ammonium aqueous solution. These results suggest an important role of alkalinity of slurries on the following two processes; (1) alkaline dissolution of ZSM-5 zeolite and (2) formation of mesoporous structure. These successive processes were efficiently improved by use of a continuous-flow reactor. The mesoporous material synthesized in the continuous-flow reactor catalyzed the cracking of cumene at 523 K, while a conventional Al-MCM-41 hardly catalyzed. The mesoporous material synthesized by using the filtrate of alkaline dissolution of ZSM-5 possessed a stronger Bronsted acidity than a conventional Al-MCM-41. (C) 2004 Elsevier Inc.

  • Textural and catalytic properties of MCM-22 zeolite crystallized by the vapor-phase transport method

    BULLETIN OF THE CHEMICAL SOCIETY OF JAPAN   77 ( 6 ) 1249 - 1254  2004年06月

    　概要を見る

    MCM-22 zeolite crystallized by the vapor-phase transport (VPT) method showed a higher shape-selectivity to p-xylene in the alkylation of toluene with methanol, compared with MCM-22 crystallized by the hydrothermally synthetic (HTS) method, because VPT-MCM-22 has a smaller external surface area and a smaller number of acid sites thereon than HTS-MCM-22. Such textural properties of VPT-MCM-22 are caused by the fact that the spherical particles of VPT-MCM-22 are composed of hexagonal plates as thin as 55 nm; they are larger than those of HTS-MCM-22, which are 30 nm thick. The acidic properties, characterized by NH3-TPD and FT-IR using a pyridine adsorption technique, showed no significant difference between VPT- and HTS-MCM-22, except for the acidity on the external surface.

  • The control of phase and orientation in zeolite membranes by the secondary growth method

    G Li, E Kikuchi, M Matsukata

    MICROPOROUS AND MESOPOROUS MATERIALS   62 ( 3 ) 211 - 220  2003年08月

    　概要を見る

    Mordenite and ZSM-5 seeds could grow on the surface of an asymmetric alpha-Al2O3 support using an identical organic-free aluminosilicate solution under the same hydrothermal conditions. It suggests that the phase of zeolite can be controlled by varying the type of seed. Continuous mordenite and ZSM-5 membranes were prepared by the secondary growth method using corresponding seeds under appropriate conditions. The water content in the secondary growth mixture strongly influenced the growth of zeolite crystals. ZSM-5 seeds grew at a smaller rate and showed a habit of thin hexagonal plate in a concentrated mixture, while the crystals with a habit of rectangular parallelepiped were formed from a diluted secondary growth mixture. ZSM-5 crystals had poor intergrowth in the former case, whereas the crystals were highly intergrown in the latter case. ZSM-5 crystals in either membrane have a random orientation. In contrast to ZSM-5 zeolite, the crystal orientation in the secondary grown mordenite membranes strongly depended on the water content in the secondary growth mixture. The crystals in the mordenite membrane developed in a diluted secondary growth mixture were oriented with the (1 5 0) face parallel to the support surface, whereas the crystals in the membrane grown in a concentrated mixture were oriented with the (0 0 2) face parallel to the support surface. These results suggest that the crystal orientation in mordenite membranes can be manipulated only by changing the water content in a secondary growth mixture. The formation of the preferred crystal orientation in the secondary grown mordenite membrane is discussed in terms of an "evolutionary selection" process. (C) 2003 Elsevier Inc. All rights reserved.

  • A study on the pervaporation of water-acetic acid mixtures through ZSM-5 zeolite membranes

    　概要を見る

    A study was carried out on the pervaporation of water from water-acetic acid mixtures through tubular ZSM-5 zeolite membranes. ZSM-5 zeolite membranes were prepared on the outer surface of a porous a-alumina tube by the seed-assisted crystallization method in the absence of organic templates. It was observed that water preferentially permeated with selectivities higher than the selectivity based on the vapor-liquid equilibrium in the entire range of acetic acid concentration. The separation mechanism of water through ZSM-5 zeolite membranes was discussed and compared with that through mordenite membranes. It was found that the permeability coefficients of both water and acetic acid decreased with increasing temperature, although the pervaporation fluxes of both water and acetic acid increased. As a result, it was concluded that the increase in the pervaporation flux with temperature was due to the increase in the driving force in terms of transmembrane partial vapor pressure difference with temperature. According to the mechanism proposed herein, a study was also directed to modify as-synthesized membranes for the improvement in their pervaporation performance. It was observed that both the water flux and the separation factor were increased through a membrane treated in alkaline solution under appropriate conditions. (C) 2003 Elsevier Science B.V.

Three different methods, a solid-state reaction method, an evaporation-to-dryness method, and a combined citrate and EDTA complexing method, were applied for the preparation of parent powder. The oxygen flux through membrane at 900 degreesC was increased in the order listed above. The oxygen flux could be greatly improved by repeated calcination and grinding of parent powder. The membrane sintered at a temperature as high as 1200 degreesC showed a higher oxygen flux (0.22 cm(3) (STP)/cm(2) min). (C) 2003 Elsevier Science B.V. All rights reserved.

    Template-free nanosized ZSM-5 seeds were prepared from commercially available ZSM-5 powder. By use of these seeds, thin and hydrophilic ZSM-5 zeolite membranes were prepared on the outer surface of a porous a-alumina tube in a clear solution free from organic template. The membranes showed high thermal stability to withstand pretreatment at 400 degreesC, At 270 degreesC, the ideal selectivities for H-2/i-butane and N-2/SF6 were 61 and 20, respectively. The membrane was effective to separate butane isomers at high temperatures. The maximum of the n/i-butane ideal selectivity was 36 at 300 degreesC. The separation factors for a 50/50 n/i-butane mixture were as high as 13 in the temperature range from 300 to 400 degreesC. (C) 2003 Elsevier Science Inc. All rights reserved.

    　概要を見る

    Zeolite beta with SiO2/Al2O3 ratios from 30 to 730 was synthesized by a steam-assisted crystallization method, and the crystallized products obtained within 24 h were characterized by means of chemical analyses, XRD, FE-SEM, Si-29- MAS NMR, N-2 adsorption, and temperature-programmed decomposition of tetraethylammonium cation occluded in the micropores of zeolite beta. Based on these results, the crystallization mechanism is discussed herein. It was found that agglomerates of nano-particles were formed from a dry gel before the development of a periodical structure in a long-range order, which can be detected by XRD. After several hours of crystallization, morphological changes in nano-particle agglomerates proceeded to give highly crystalline zeolite beta. (C) 2002 Elsevier Science Inc. All rights reserved.

    　概要を見る

    A high-silica hexagonal faujasite EMT was crystallized by a steam-assisted crystallization (SAC) method using a crown ether of 1,4,7,10,13,16-hexaoxacyclooctadecane, 18-crown-6, as a structure-directing agent. The growth mechanism of EMT by SAC is quite different from that of EMT by the conventional hydrothermal synthetic method, in which layer-by-layer growth occurs. Another characteristic of SAC is that nanoparticles fuse and the surface of the dry gel is rearranged, resulting in a distinct hexagonal shape for the EMT crystals. Sodium content must be strictly defined when the SAC method is used, and the crystallization temperature must be kept below 408 K to keep the crown ether in the dry gel to obtain a pure phase of EMT.

    Beta zeolites with a wide range of Si/2Al ratios from 7 to infinity were synthesized by steam-assisted crystallization method. X-ray diffraction, FE-SEM, and MASNMR studies confirmed the formation of highly crystalline zeolite beta and Al incorporation in the framework under various conditions by the SAC method at temperatures ranging from 373 to 438 K. Na+ and TEA(+) contents occluded in micropores of beta zeolite were determined. Quantitative knowledge on such occluded cations gave great insight on understanding crystallization mechanism of beta.

  • Effect of NH+ 4 Exchange on Hydrophobicity and Catalytic Properties of Al-Free Ti-Si-beta Zeolite

    Journal of Catalysis   199 ( 1 ) 41 - 47  2001年04月

    　概要を見る

    Al-free Ti-Si-beta was synthesized by a steam-assisted crystallization (SAC) method using tetraethylammonium hydroxide as a structure-directing agent. It was noted that Na in a parent gel was essential for synthesizing highly crystalline Ti-Si-beta by means of the SAC method. An absorption band at 225 nm, assigned to isolated Ti species, and another band at around 270 nm appeared in the UV spectra of the Ti-Si-beta. The latter absorption band decreased upon ion exchange of as-synthesized materials with 1 M aqueous NH4NO3 solution, and this treatment did not change the SiO2/TiO2 molar ratio in Ti-Si-beta. The Q3 signal in the 29Si-NMR spectrum almost disappeared and the amount of H2O adsorbed decreased due to the NH+ 4 exchange of Ti-Si-beta. The NH+ 4 exchange resulted in a higher catalytic activity of the zeolite for cyclohexene epoxidation with H2O2 and a high selectivity toward epoxide compared with the H2SO4-treated Ti-Si-beta and Al-containing Ti-beta samples prepared in this study. Summarizing these results, the NH+ 4 exchange of Ti-Si-beta zeolite is found to induce a hydrophobic environment around Ti sites without detitanation from the zeolite frame-work. © 2001 Academic Press.

    　概要を見る

    Selective removal of hydrogen in a membrane reactor enables the hydrogen production by steam reforming at lower reaction temperatures than conventional processes. We invented a composite membrane consisting of thin palladium layer deposited on the outer surface of porous ceramics by electroless-plating. The palladium layer could completely cover the surface, so that only hydrogen could permeate through the membrane with a 100% selectivity. By use of this kind of membrane, Tokyo Gas and Mitsubishi Heavy Industries have developed a membrane reformer applicable to the polymer electrolyte fuel cell system. Our current approach is the application of a CVD technique to deposit non-Pd metals, such as Pt, to overcome the limitations caused by Pd membranes, such as hydrogen embrittlement. The permeability and permeation selectivity of these metal-ceramic composite CVD membranes were investigated in a comparison with electroless-plating palladium membranes, as well as the performance in membrane reactors applied to steam reforming of methane. The permeation of hydrogen through the CVD membranes is not based on the solution-diffusion transport mechanism but on the surface diffusion mechanism. Although the CVD membranes gave higher conversion of methane than thermodynamic equilibrium, their performance became similar to electroless-plating membranes, only when the membranes showed high H2/N2 separation factors. © 2000 Elsevier Science B.V All rights reserved.

    　概要を見る

    This article is intended to describe recent progress in the synthesis of zeolitic membranes and their permeation properties. While hydrothermal synthesis has been widely employed for zeolitic-membrane synthesis, the development of a new technique for zeolite synthesis, vapor-phase transport (VPT), has enabled us to prepare pinhole-free, zeolite-porous support composite membranes. This article consists of three sections that describe: a survey of the hydrothermal synthesis of zeolitic membranes, our synthesis results and the formation mechanism of zeolitic membranes by the VPT method as well as some permeation results to show the prospects of zeolitic membranes.

    　概要を見る

    YBa2Cu3Ox, known as a high-Tc superconductor, was used as an electroconductive catalyst and its characteristics in CO oxidation were investigated. Charging 3 V, direct current, heated YBa2Cu3Ox up to about 500°C, at which it could catalyze CO oxidation. Thus, this oxide has proper features required for electrically temperature-controlled combustion catalysts: one is self-heating property caused by electric current (Joule's heat) and the other is catalytic activity for combustion. The catalytic activity of YBa2Cu3Ox was greatly affected by the oxygen deficiency in the solid which was directly related to the partial pressure of oxygen in the reaction system.

    　概要を見る

    Selective and efficient permeation of H2 was accomplished by a thin Pd or Pd-Ag alloy membrane supported on porous alumina ceramics. Such membranes were prepared by deposition of Pd or Pd and Ag on the outer surface of the support cylinder by an electroless plating technique. It was found that either steam or CO2 reforming of CH4 was promoted beyond equilibrium by use of a membrane reactor with the Pd/ceramic composite membrane at temperatures as low as 773 K. In spite of a similar type of reforming, a quite different pattern of reaction products was obtained in the membrane reactor: H2 and CO2 from steam reforming, and H2 and CO (syngas) from CO2 reforming. Nickel catalyzed carbon-free steam reforming, and the level of CH4 conversion depended on the efficiency of the membrane for H2 permeation since the rate of H2 production was sufficiently higher than that of H2 permeation. On the contrary, carbon deposition extensively took place in CO2 reforming on Ni catalyst, while alumina-supported noble metals showed far less selectivities for carbon deposition than did Ni even in the membrane reactor. Differing from the activity sequence observed in the conventional reaction system, it was found in membrane reactor that it decreased in the order: Rh∼Pt&gt
    Pd&gt
    Ru&gt
    Ir, due to contamination of the active surface. Among the noble metal catalysts tested, Pt supported on Al2O3-La2O3 and Al2O3-CeO2 was effective without significant carbon deposition to enable prolonged activity. The membrane reactor can provide a partial oxidation process with utilization of air instead of pure O2 to produce H2 or syngas.

    　概要を見る

    Plating thin Pd or Pd-Ag alloy film on the outer surface of a porous alumina ceramic tube enables very rapid hydrogen permeation with an absolute selectivity based on the solution-diffusion transport mechanism. Effectiveness, such as displacement of thermodynamic equilibrium, selectivity enhancement, is brought forth by incorporating the metal/ceramic composite membrane in the catalytic reactor, as demonstrated in concrete examples of steam and CO2 reforming of methane and dehydrogenation of isobutane. It is also shown that the membrane reactor occasionally requires its own catalyst which is different from conventional ones. © 1995.

  • Liquid-phase methanol synthesis on Cu-based ultrafine particles prepared by chemical deposition in liquid phase

    　概要を見る

    Liquid-phase methanol synthesis was investigated using copper-based ultrafine particle (UFP) catalysts. Cu{single bond}Zn UFP catalyst was active for methanol synthesis, although the activity decreased with time-on-stream. Cu{single bond}V UFP catalyst was stable against deactivation and showed the highest methanol productivity of the catalysts tested. The space time yield of methanol on this catalyst was about 3.5 times as large as that of a co-precipitated Cu{single bond}Zn catalyst. The selectivity of the Cu{single bond}V UFP catalyst for methanol was low, as compared to that of the co-precipitated Cu{single bond}Zn catalyst, due to the formation of methane. The addition of carbon dioxide in the feed gas was effective in suppressing the formation of methane. © 1995 Elsevier Science B.V. All rights reserved.

    　概要を見る

    Selective reduction of NO by CH4 on zeolite catalysts has been studied. After an investigation of the catalytic features of various cation-exchanged zeolites, we found that Ga-ZSM-5 and In-ZSM-5 were highly active and selective for NO reduction by CH4. We also showed that this reaction was moderately promoted even by H-form ZSM-5, mordenite, and ferrierite. From the catalytic performance of Ga-and In-ZSM-5 in NO-CH4-O2, NO2-CH4-O2, and NO-O2 reactions, it is concluded that the selective reduction of NO on these catalysts proceeds in two stages: (1) NO is oxidized to NO2 on zeolite acid sites, (2) NO2 and CH4 react on gallium or indium sites. The highly selective features of Ga and In in the zeolite for the NO2-CH4 reaction seem to be attributed to the coordinatively unsaturated nature of these sites which adsorb both of these reactants on the same site. Effect of water vapor on NO conversion was also investigated. It was found that Ga-ZSM-5 was strongly inhibited by steam, while In-ZSM-5 was fairly active even in the presence of 10% steam. © 1994.

    　概要を見る

    The concept of shape selectivity is available to produce symmetrical dinuclear aromatic hydrocarbons such as 2,6-dialkylnaphthalene and 4,4′-dialkylbiphenyl, which are the raw materials for liquid crystals and polyester with superior properties, respectively. The ZSM-5 catalyst exhibits high activity and selectivity for the formation of p-xylene in the disproportionation and alkylation of toluene. The catalytic activity of ZSM-5 for the conversion of naphthalene derivatives is markedly low due to its small pore size, although symmetrical dinuclear aromatic hydrocarbons are selectively formed. The high catalytic activity is obtained with twelve-membered ring zeolites. Among these zeolites, mordenite is the most selective catalyst to produce symmetrical dinuclear aromatic hydrocarbons. The precise controls of the size of pore opening and the acidic property are required to enhance the selectivity for symmetrical dinuclear aromatic hydrocarbons. The non-zeolitic molecular sieves also present a great opportunity in high selective synthesis of these compounds. © 1993 VSP.

  • ＣＯ変成用新規ペロブスカイト型酸化物触媒の開発

    2006年  

    　概要を見る

    燃料電池用の水素製造においては、改質ガス中のCO除去プロセス（COシフト反応→CO選択酸化）が必要不可欠となっており，現在のPt電極性能では10 ppm以下へのCO濃度低減が要求される．COシフト反応には工業的にCu-Zn系酸化物触媒が用いられているが，PEFC特有のDSS（デイリースタートアップ＆シャットダウン）運転では，酸化雰囲気に弱い従来のCu-Zn系酸化物触媒の使用は困難とされており，酸化雰囲気に強く，低温，高空間速度で高活性な新規触媒の開発が求められている．本研究では高い酸素イオン伝導性を有するペロブスカイト型酸化物に注目し，これを触媒担体として用いて，低温での水性ガスシフト反応を検討した．触媒の格子酸素が反応に寄与するRedox機構で進行させることができるのなら，DSSでの酸化に強い触媒系となることが期待される．さらにPt, Pdなどの活性金属を担持することで格子酸素の再生・放出を促進し，Redox領域の低温化を図り，検討を行った．その結果、Pt, PdとLaCoO3を組み合わせた触媒を用いた場合、Pt/LaCoO3とPd/LaCoO3は高いシフト活性を示した．活性が低い触媒の反応前後の結晶構造はほとんど変化していないのに対し，高活性を示したPt/LaCoO3, Pd/LaCoO3についてはLaCoO3に起因するピークが低角度側にシフトし，ブロードとなる変化がみられた．これは反応中に格子酸素が放出され，ペロブスカイト型構造が歪んでしまったためと考えられる．また，Air処理による検討から，活性低下の原因と反応中での結晶構造の変化には相関がないと考えられる．XPS測定により，Pt, Pdの電子状態を解析した．その結果，Pt/LaCoO3ではPt2+-2がシフト反応に大きく寄与していることがわかり，活性低下の原因はPt2+-2が反応中に還元されるためと考えられた．また，Pd/LaCoO3ではPd種がRedoxしており，安定した活性種となっていることが示唆された．これを受けて，安定なRedoxサイクルを進行するPd種がPt種の還元を抑制するようなシナジー効果を期待し，Pt-Pd/LaCoO3触媒を検討したところ，1 wt%Pt-0.5 wt%Pd/LaCoO3は商用触媒の活性を上回る高活性触媒となった．

    メタン水蒸気改質反応用Ni触媒としてペロブスカイト型酸化物を適用することで、工業的に用いられるアルミナなどの担体とした場合と比較し、高い耐炭素析出安定性が得られることが見出されている。これは担体中の格子酸素が反応に関与し、メタンがNi上に解離吸着して生成したCHXの酸化及び析出炭素前駆体の酸化除去を促進したためと考えられる。本研究では、H218Oを用いた過渡応答解析により、格子酸素が反応に関与するメカニズムの実証、また、格子酸素の挙動に影響する因子の検討を目的とした。実験では、ペロブスカイト担体として錯体重合法にて調製したLaAlO3, SrTiO3を用いた。これらペロブスカイトにニッケルを担持し触媒とした。反応における過渡応答解析は固定床常圧流通式反応器を用いた。反応は、あらかじめ水素気流で還元した触媒を用いて、反応温度1073 K,で行った。Heで60分間パージした後、CH4/H216O/Ar/He を60分間供給し、CH4/H218O/Ar/Heに切り替えて5分間保持し後、再びCH4/H216O/Ar/Heに切り替え、そのときの過渡応答を四重極形質量分析装置（QMS、HYDEN HAL201）により解析した。　格子酸素によるCH4酸化実験より、触媒活性と、格子酸素によるCHXの酸化速度との間に相関あることが示唆された。また、H2Oからの格子酸素補充の検討を行ったところ、格子酸素の補充には担持金属が大きく影響しており、担持金属が酸化された状態では格子酸素の補充が行われないと考えられる。そして、H218Oを用いた過渡応答解析より、ペロブスカイト担体の格子酸素が反応に関与することが明らかになった。反応温度が高いほど反応に関与する格子酸素量は多いと考えられ、またCHXの酸化により関与すると考えられる。最後に、格子酸素の反応には金属－担体界面が大きく関わっており、Ni粒子径が小さいほど、反応に関与する格子酸素量が多くなることがわかった。
