The invention concerns a composition with base of cerium oxide or cerium and zirconium oxide, in extruded form, its method of preparation and its use as catalyst. The method of preparation of this composition is characterised in that it consists in extruding a hydroxide or an oxygen hydroxide of cerium or hydroxides or oxygen hydroxides of cerium and zirconium. The composition can be used as catalyst or catalyst support, particularly in the treatment of exhaust gases of internal combustion engines, in the process of dehydrogenation of ethyl benzene into styrene, in methanation catalysis, in the treatment of a solution or suspension of organic compounds by wet oxidation.
La présente invention concerne une composition à base d'oxyde de cérium ou d'oxydes de cérium et de zirconium, sous forme extrudée, son procédé de préparation et son utilisation comme catalyseur. Le procédé de préparation de la composition de l'invention est caractérisé en ce qu'on extrude un hydroxyde ou oxyhydroxyde de cérium ou des hydroxydes ou oxyhydroxydes de cérium et de zirconium. La composition de l'invention peut être utilisée comme catalyseur ou support de catalyseur, notamment dans le traitement des gaz d'échappement des moteurs à combustion interne, dans le procédé de déshydrogénation de l'éthylbenzène en styrène, dans la catalyse de méthanation, dans le traitement d'une solution ou suspension de composés organiques par oxydation en voie humide.
