METHOD OF REACTIVATION OF CATALYST

摘要

PURPOSE: To reactivate a spent metal contaminated zeolite-contg. catalytic cracking catalyst compsn. CONSTITUTION: A spent metal contaminated zeolite-contg. catalytic cracking catalyst compsn is reactivated by a process characterized in that it is brought into contact with an aq. soln. of HCl and/or HNO3 and/or H2 SO4 . The thus reactivated catalyst compsn. can be used in a catalytic cracking process.
