CA 2053703

A catalyst composition for purification of exhaust gas, comprising (a) high-silica zeolite having a Si/Al ratio of 40 or more, subjected to ion exchange with at least one metal selected from Pt, Pd, Rh, Ir and Ru, and (b) a heat-resistant oxide containing at least one metal selected from Pt, Pd, Rh, Ir and Ru; a catalyst for purification of exhaust gas, comprising a monolith carrier and the catalyst composition supported on the carrier; and a process for producing the catalyst. The catalyst has high activity for exhaust gas purification even when the catalyst contains Rh which is an expensive catalyst component, in a very small amount.

Composition catalytique pour la purification de gaz d'échappement, renfermant (a) une zéolite à forte teneur en silice, dont le rapport Si/Al est de 40 ou plus, soumise à un échange ionique avec au moins un métal choisi parmi Pt, Pd, Rh, Ir et Ru, et (b) un oxyde thermorésistant renfermant au moins un métal choisi parmi Pt, Pd, Rh, Ir et Ru; catalyseur pour la purification de gaz d'échappement, renfermant un véhicule monolithique et la composition catalytique sur le véhicule comme support; méthode de préparation du catalyseur. Le catalyseur est très actif pour la purification des gaz d'échappement, même lorsqu'il renferme du Rh, composante catalytique coûteuse, en très faibles quantités.
