Catalytic cracking process. [removal of V, Ni, Fe contaminants from catalyst]

Abstract

This invention relates to a process for catalytically cracking hydrocarbon feedstocks containing a contaminant deleterious to the process and catalyst and to a method for removing the contaminant from a crystalline aluminosilicate cracking catalyst used in the process, where the contaminant is vanadium, or vanadium and nickel, and optionally iron.
