RARE EARTH BINDER-CONTAINING ADDITIVES AND CATALYSTS

摘要

Catalytic cracking catalysts and additives which comprise a rare earth binder component are especially useful for catalytic cracking processes involving hydrocarbon feedstocks containing high metals content. The catalysts and additives may be used in conjunction with zeolite-containing cracking catalysts to enhance catalytic activity/selectivity especially for vanadium-containing hydrocarbon feedstocks. The rare earth binder component is preferably derived from a rare earth acid sol.
