ABSTRACT:
A spent zeolite-containing catalytic cracking catalyst composition is reactivated by a process comprising the steps of contacting the catalyst composition with a solution of a suitable ammonium compound (preferably an aqueous solution of NH.sub.4 NO.sub.3) and thereafter contacting the ammonium-exchanged cracking catalyst composition with a suitable fluorine compound (preferably a aqueous solution of NH.sub.4 F). A catalytic cracking process employs the reactivated cracking catalyst composition.
