ABSTRACT:
A process for preparing an oxidic, carrier catalyst comprising at least one heavy metal compound as active component, said process comprising providing a carrier comprising a temperature resistant material with a catalytically active coating by intensively mixing said carrier with a binding agent, and at least one pulverulent, oxidic heavy metal compound or with a pulverulent mass containing at least one of said oxidic heavy metal compounds or at least one hydroxyl group-containing precursor of said heavy metal compounds, and subsequently heating the resulting mass to remove said binding agent. The catalyst and the process of using the catalyst in the purification of exhaust gases are provided.
