Title (EN) EXHAUST GAS PURIFYING CATALYST
(FR) CATALYSEUR DE PURIFICATION DE GAZ D'ECHAPPEMENT
Abstract: front page image
(EN)An exhaust gas purifying catalyst that provides the excellent low-temperature activity and also develops the good catalytic activity of rhodium to produce a good purifying performance economically. The exhaust gas purifying catalyst comprises an alumina on which rhodium and platinum are previously supported; a zirconium complex oxide on which rhodium and platinum are previously supported; and a cerium complex oxide on which platinum is previously supported.
(FR)Cette invention concerne un catalyseur de purification de gaz d'échappement qui permet d'obtenir une excellente activité à basse température et qui développe l'activité catalytique adéquate du rhodium pour que de bonnes performances de purification économiques soient obtenues. Ce catalyseur de purification de gaz d'échappement comprend : une alumine sur laquelle le rhodium et le platine reposent initialement ; un complexe oxyde de zirconium sur lequel le rhodium et le platine reposent initialement ; et un complexe oxyde de cérium sur lequel le platine repose initialement.
