ABSTRACT:
A spent metal contaminated zeolite-containing catalytic cracking catalyst composition is reactivated by a process which comprises contacting with an aqueous solution of HC1 and/or HNO.sub.3 and/or H.sub.2 SO.sub.4. The thus reactivated catalyst composition can be employed in a catalytic cracking process.
