ABSTRACT:
A process for reactivating a spent, metal-contaminated zeolite-containing catalytic cracking catalyst composition comprises contacting the spent catalyst composition with an acidified aqueous NH.sub.4 NO.sub.3 solution, thereafter with a suitable fluorine compound (preferably dissolved NH.sub.4 F), and, optionally, additionally with an antimony compound. The thus prepared reactivated cracking catalyst composition is used in a process for catalytically cracking a liquid hydrocarbon-containing feed.
