Abstract

Procedure for the preparation of a supported catalyst, characterized in that aluminum oxide containing water or an unstable anhydrous aluminum oxide is compressed to form molded bodies; why the molded bodies are calcined for 10 to 20 hours at temperatures of 1000 to 1250ºC; because the calcined molded bodies are impregnated with the aqueous solution of a cerium salt of an easily decomposable acid; because the cerium salt applied on the molded bodies dries at 130 to 150ºC; because the dried cerium salt on the shaped bodies decomposes by step heating at temperatures of 200 to 300ºC and 450 to 550ºC, and then the shaped bodies containing cerium oxide are calcined at temperatures of 700 to 900ºC .
