Title (EN) FUEL REFORMING CATALYST
(FR) CATALYSEUR DE REFORMAGE DE COMBUSTIBLE
(JA) 燃料改質触媒
Abstract:
(EN) The purpose of the present invention is to provide a novel fuel reforming catalyst capable of effectively lowering the concentration of C2 or higher hydrocarbons in a gas produced in a steam reforming reaction. The present invention proposes a fuel reforming catalyst which contains catalyst particles including a porous inorganic carrier, a catalytically active species, CeO2 and ZrO2, wherein the fuel reforming catalyst is characterized in that the concentration of ZrO2 in catalyst particles is higher near the surface of the particles than in the inner part of the particles and the concentration of CeO2 in the catalyst particles is approximately equal in the inner part of the particles and near the surface of the particles.
(FR) La présente invention vise à fournir un nouveau catalyseur de reformage de combustible pouvant réduire efficacement la concentration d'hydrocarbures C2 ou supérieurs dans un gaz produit dans une réaction de reformage à la vapeur. La présente invention concerne un catalyseur de reformage de combustible, qui contient des particules de catalyseur comprenant un support inorganique poreux, une espèce catalytiquement active, CeO2 et ZrO2, le catalyseur de reformage de combustible étant caractérisé par le fait que la concentration de ZrO2 dans des particules de catalyseur est plus élevée près de la surface des particules que dans la partie interne des particules, et que la concentration de CeO2 dans les particules de catalyseur est approximativement égale dans la partie interne des particules et près de la surface des particules.
(JA)  水蒸気改質反応を経たガスにおける、C2以上の炭化水素の濃度を有効に低減することができる、新たな燃料改質触媒を提供する目的で、無機多孔質担体と、触媒活性種と、CeO2と、ZrO2とを含む触媒粒子を含有する燃料改質触媒であって、触媒粒子におけるZrO2の濃度は、粒子内部よりも粒子表面近傍の方が高くなっており、且つ、該触媒粒子におけるCeO2の濃度は、粒子内部と粒子表面近傍とが同等であることを特徴とする燃料改質触媒を提案する。
