摘要： Hydrocarbon-containing feed streams (preferably heavy gas oils and hydrotreated residua) having an initial boiling point of at least 400.degree. F. are catalytically cracked in the presence of a cracking catalyst comprising a faujasite-type zeolite having a unit cell size of about 24.28-24.48 A and an an alkali metal content of less than about 0.5 weight percent and being substantially free of iron ions. Preferably, the faujasite-type zeolite has an atomic Si:Al ratio in the crystalline framework of about 8:1 to 21:1 and has been partially dealuminated by a process comprising steam treatment followed by acid leaching.

摘要： 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.
