ABSTRACT:
A process for reactivating a spent, metal-contaminated zeolite-containing cracking catalyst composition comprises the sequential steps of contacting the catalyst composition with dissolved ammonium compound (preferably NH.sub.4 NO.sub.3), contacting with a fluorine compound (preferably NH.sub.4 F), and treatment with a passivating agent (preferably Mg, Ca, B, A, P and/or Sb). The reactivated cracking catalyst obtained by this reactivation process is employed in a catalytic cracking process.
