ABSTRACT OF THE DISCLOSURE It is now known that molecular sieve cracking catalysts used in fluid catalytic cracking units which have been contaminated with such metals as vanadium and nickel can be restored by contacting such contaminated catalysts with antimony-containing compounds and then subsequently subjecting the thus-treated catalysts to elevated temperatures and an oxygen-containing gas whereby revitalization is achieved. The above process can be improved by using as a source of antimony oxide an oil-in-water emulsion of an aqueous antimony sol.
