Fu, C M

A catalytic cracking process is described, comprising the step of contacting a hydrocarbon-containing feed stream with a catalytic cracking catalyst composition comprising a zeolite, under such catalytic cracking conditions as to obtain at least one normally liquid hydrocarbon-containing product stream having a lower initial boiling point and higher API gravity than the hydrocarbon-containing feed stream. A portion of the catalytic cracking catalyst composition is a reactivated spent catalytic cracking catalyst composition having undergone a process comprising the steps of: (a) contacting a spent zeolite-containing catalytic cracking catalyst composition with a solution of an ammonium compound other than ammonium fluoride, under such contacting conditions as to enhance the catalytic cracking activity of the catalytic cracking catalyst composition; (b) at least partially separating the catalytic cracking catalyst composition; (c) contacting at least partially separated catalytic cracking catalyst composition with a suitable fluorine compound; and (d) heating the catalytic cracking catalyst composition under such conditions as to obtain a dried, reactivated catalytic cracking catalyst composition.
