Title (EN) HONEYCOMB CATALYST
(FR) CATALYSEUR EN NID D'ABEILLES
(JA) ハニカム触媒
Abstract:
(EN) The present invention relates to a honeycomb catalyst which is obtained by supporting a noble metal on a honeycomb structure in which a plurality of through holes are arranged side by side in the longitudinal direction with partition walls interposed therebetween. The honeycomb catalyst is characterized in that: the partition walls comprise a base material part formed from an extrusion-moulded body including a ceria-zirconia composite oxide and alumina, and a coat layer which is formed on the surfaces of the base material part, and which includes the noble metal; and the thermal expansion coefficient of the partition walls in the longitudinal direction is 7.0-8.0×10-6/˚C.
(FR) La présente invention concerne un catalyseur en nid d'abeilles qui est obtenu en déposant un métal noble sur une structure en nid d'abeilles dans laquelle une pluralité de trous débouchants sont agencés côte à côte dans le sens longitudinal avec des cloisons de séparation intercalées entre eux. Le catalyseur en nid d'abeilles est caractérisé en ce que : les cloisons de séparation comprennent une section de matériau de base formée à partir d'un corps moulé par extrusion comprenant un oxyde composite de cérium-zircone et de l'alumine, et une couche de revêtement formée sur les surfaces de la section de matériau de base et qui comprend le métal noble; et le coefficient de dilatation thermique des cloisons de séparation dans le sens longitudinale est de 7,0 à 8,0×10-6/°C.
(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、上記隔壁は、セリア-ジルコニア複合酸化物とアルミナとを含む押出成形体で構成される基材部と、上記基材部の表面に形成され、上記貴金属を含むコート層とからなり、上記隔壁の長手方向の熱膨張係数が、7.0~8.0×10-6/℃であることを特徴とするハニカム触媒に関する。
