ABSTRACT:
An improved catalytic cracking process wherein partial demetallization of a cracking catalyst is employed. The demetallization process involves contacting the catalyst with alternate reductive and oxidative aqueous washes. A preferred oxidative wash medium comprises an aqueous solution of hydrogen peroxide. The vanadium and nickel metals may be recovered from used wash solutions for metallurgical use.
