Abstract
A zeolite-containing catalytic cracking catalyst having been passivated by treatment with an aqueous solution which has been prepared by mixing an antimony oxide, ammonium bifluoride and water, at an atomic ratio of F:Sb in excess of about 6:1, is used in a process for catalytically cracking a hydrocarbon-containing feed, in particular one which contains metal impurities. In one embodiment, the above-described aqueous solution is injected into the feed. In other embodiments, the solution is injected into the cracking zone or into a catalyst regeneration zone.
