“…There are several approaches to the preparation of catalysts with a high specific surface area based on the oxides of a perovskite structure. One of the possible ways is to fix the active component on the surface of an inert oxide or to introduce it into ceramic/cermet foamy supports [7]. Another method to obtain the sample of a high specific surface area is template synthesis, which includes the use of a high surface area template at the precursor compound formation stage [8].…”

LaCoO3 perovskite-type catalysts in syngas conversion

AbstractLaCoO3 samples were obtained by the hydrothermal and citrate methods. The dynamics of the phase transformations of the initial hydroxo compounds into the oxide state and the subsequent reduction in a hydrogen-containing mixture were studied by the differential thermal analysis and X-ray diffraction methods. The results of the catalytic tests in the syngas conversion showed that the path of conversion depends on the phase composition of the catalyst in the oxide state. In contrast to the standard CoAl sample, alcohols prevail in the liquid products formed on LaCoO3 catalysts.

“…Liu and Lin [19,20] studied glycerol ATR on coated forms of LaMnO 3 and LaNiO 3 perovskites in monolith reactors and found that the latter favored H 2 production, which was possible on LaMnO 3 by Pt promotion to give ∼60% and ∼40% selectivity towards H 2 and CO, respectively. Use of structured reactors for glycerol ATR was also studied by Sadykov et al [21,22]. The authors tested Ni-Ru catalyst integrated to a metallic substrate with high thermal conductivity, and observed near equilibrium syngas yields with no transport resistances.…”

“…The authors tested Ni-Ru catalyst integrated to a metallic substrate with high thermal conductivity, and observed near equilibrium syngas yields with no transport resistances. They also emphasized the importance of optimizing the amount of O 2 in the feed for improving catalyst stability via reduced coking [22]. Oxidative conversion of glycerol in the absence and presence of inlet H 2 O vapor was studied at 900-1200°C and C/O = 0.8-1.6 in a different catalyst geometry dictated by α-Al 2 O 3 foam on which Rh-Ce/γ-Al 2 O 3 was washcoated [23].…”

“…Другим перспективным применением ВПЯМ системы Fe-Cr-Al являются структурированные носители катализаторов для превращения природного газа и биотоплива в сингаз и водород [4] и глубокого окисления метана [5,6]. Рабочие температуры ВПЯМ-хромаль при этом лежат в среднем интервале температур (600…800 °C), где они могут конкурировать с материалами аналогичной структуры на основе керамик [7].…”

The highly permeable cellular material (HPCM) based on chromal is promising as a carrier of deep methane oxidation catalysts. Using HPCM as a base material of heat-resistant Fe-Cr-Al alloys allows to apply such catalysts at temperatures up to 900 °C in the air and in the combustion gas atmosphere. HPCM-chromal is the basis for flameless combustion of methane catalysts for environmental friendly heat generators. HPCM based on Fe-Cr-Al is used as the heat and power unit the catalytic reactor-steam generator, allowing performing deep flameless oxidation of the fuel in the reactor at temperatures below 1000 °C, which virtually eliminates the formation of oxides of nitrogen NOx and CO. HPCM based on Fe-Cr-Al is obtained by powder metallurgy by replicating the spatial structure of polymeric cellular material. The materials are prepared from the slurry based on the mixture of carbonyl iron powder and master alloy (wt.%) 20 % Fe-60 % Cr-20 % Al with the addition of 1.5% Co fine powder. Technique involves ligature milling, powders mixing, preparation and application to polymer backbone slurry, preliminary annealing in hydrogen, with a step by heating to 700°C for decomposition and removal of the polymer and the final sintering in vacuum at 1270 °C. The results of X-ray study highly porous cellular material of Fe-Cr-Al are showed. The data on the phase composition, the lattice parameters and the fine structure of the starting powder and the charge is showed. Material is investigated after intermediate annealing at 700 °C and after sintering at 1270 °C. After intermediate annealing at 700° material consists of 3 bcc phases with differing parameters. After the final sintering material consists of a bcc phase and impurities of chromium carbide Cr 7 C 3 .
