Title (EN) HONEYCOMB CATALYST
(FR) CATALYSEUR EN NID D'ABEILLES
(JA) ハニカム触媒
Abstract:
(EN) The present invention pertains to a honeycomb catalyst in which a precious metal is supported on a honeycomb structure in which a plurality of through-holes are arranged in the lengthwise direction and separated by a partition, the honeycomb catalyst being characterized in that: the honeycomb structure contains a ceria-zirconia composite oxide and alumina; the partition comprises a first support layer having Rh supported therein and positioned on the surface of the partition, and a second support layer having Pd supported therein and positioned farther to the inside of the partition than is the first support layer; and the Pd concentration of the second support layer on the first support layer side thereof is higher than the Pd concentration in the center of the second support layer.
(FR) L'invention concerne un catalyseur en nid d'abeilles qui est constitué par support d'un métal noble sur une structure en nid d'abeilles dans laquelle une pluralité de trous traversant est séparée par des parois de séparation et rangée dans une direction longitudinale. Ce catalyseur en nid d'abeilles est caractéristiques en ce que ladite structure en nid d'abeilles contient un oxyde complexe cérium-zircone et une alumine. Lesdites parois de séparation sont constituées d'une première couche de support disposée à leur surface et supportant un Rh, et d'une seconde couche de support disposée au niveau de leur côté interne par rapport à ladite première couche de support et supportant un Pd, la concentration en Pd côté première couche de support de ladite seconde couche de support, étant supérieure à la concentration en Pd au centre de ladite seconde couche de support.
(JA) 本発明は、複数の貫通孔が隔壁を隔てて長手方向に並設されたハニカム構造体に貴金属が担持されてなるハニカム触媒であって、上記ハニカム構造体は、セリア-ジルコニア複合酸化物とアルミナとを含み、上記隔壁は、隔壁の表面に配置され、Rhが担持された第1担持層と、上記第1担持層よりも隔壁の内側に配置され、Pdが担持された第2担持層からなり、上記第2担持層の上記第1担持層側におけるPd濃度は、上記第2担持層の中心におけるPd濃度よりも高いことを特徴とするハニカム触媒に関する。
