    摘要: A catalytic cracking catalyst comprising zeolite, kaolin, alumina and/or silica, antimony and 100-5,000 wt. ppm Ni is disclosed. The Ni-antimony interact in the environment of a fluidized catalytic cracking reactor to increase the magnetic susceptibility of the catalyst, permitting removal of nickel contaminated catalyst by magnetic separation.

    摘要: A zeolite-containing cracking catalyst is passivated with compounds of boron and zirconium, and preferably also antimony. The thus-passivated cracking catalyst is employed in a process for catalytically cracking a hydrocarbon-containing oil feed. In another embodiment, compounds of boron and zirconium, and preferably also antimony, are added to a hydrocarbon-containing oil feed which is catalytically cracked in the presence of a zeolite-containing cracking catalyst.

    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.

    摘要: A catalytic cracking process especially useful for the catalytic cracking of high metals content feeds including resids in which the feed is cracked in the presence of a catalyst additive comprising a dehydrated magnesium-aluminum hydrotalcite which acts as a trap for vanadium as well as an agent for reducing the content of sulfur oxides in the regenerator flue gas. The additive is used in the form of a separate additive from the cracking catalyst particles in order to keep the vanadium away from the cracking catalyst and so preserve the activity of the catalyst.
