ABSTRACT:
A process for reactivating a spent, metal-contaminated zeolite-containing cracking catalyst composition comprises the substantially simultaneous contacting with a fluorine compound (preferably HH.sub.4 F) and a metals passivating agent (preferably a compound of Sb or Ca). The thus reactivated cracking catalyst composition is employed in a catalytic cracking process.
