Title (EN) MIXED CERIUM AND ZIRCONIUM OXIDE FOR MOTOR VEHICLE CATALYSIS
(FR) OXYDE MIXTE À BASE DE CÉRIUM ET DE ZIRCONIUM POUR LA CATALYSE AUTOMOBILE
Abstract: front page image
(EN)The present invention concerns a mixed oxide of zirconium, cerium, lanthanum and optionally at least one rare earth other than cerium and lanthanum that can be used for preparing a catalyst that maintains good catalytic activity after severe ageing. The invention also concerns a method for treating the exhaust gases of internal combustion engines using a catalyst prepared from the mixed oxide.
(FR)La présente invention concerne un oxyde mixte de zirconium, de cérium, de lanthane et éventuellement d'au moins une terre rare autre que le cérium et le lanthane permettant de préparer un catalyseur qui conserve une bonne activité catalytique après un vieillissement sévère. L'invention est aussi relative à un procédé de traitement des gaz d'échappement des moteurs à combustion interne utilisant un catalyseur préparé à partir de l'oxyde mixte.
