ABSTRACT:
A spent metal contaminated zeolite-containing catalytic cracking catalyst composition is reactivated by a process which comprises contacting with an aqueous solution of at least one carboxylic acid (preferably at least one of formic acid, acetic acid, citric acid and lactic acid). The thus reactivated catalyst composition can be employed in a catalytic cracking process.
