ABSTRACT:
An improved zeolite-containing cracking catalyst prepared by treating a zeolite-containing cracking catalyst with an aqueous solution containing a fluorine compound, drying and calcining the fluorided catalyst. In a preferred embodiment, the fluorinating solution is an aqueous solution of hydrogen fluoride. The fluorided catalyst may be used per se as a cracking catalyst, or may be physically mixed with a metallic reforming catalyst for use as a cracking catalyst. The fluorided cracking catalysts exhibit improved activity and yield higher octane products than unfluorided cracking catalysts.
