ABSTRACT:
A process for reactivating a spent, metal-contaminated zeolite-containing catalytic cracking catalyst composition comprises partially demetallizing (preferably by chlorinating and washing) the spent catalytic cracking catalyst composition, and thereafter contacting it with at least one fluorine compound (preferably NH.sub.4 F) and at least one antimony compound. The thus reactivated catalytic cracking catalyst composition is employed in a catalytic cracking process.
