FLUID CATALYTIC CRACKING CATALYST, ITS PRODUCTION METHOD AND PRODUCTION METHOD OF LOW-SULFUR CATALYTIC CRACKED GASOLINE

摘要

PROBLEM TO BE SOLVED: To provide a fluid catalytic cracking catalyst for obtaining a gasoline distillate of low-sulfur content with high yield, to provide a production method of the catalyst and to provide a production method of a low-sulfur gasoline using the catalyst. SOLUTION: The fluid catalytic cracking catalyst is yielded by supporting vanadium (V) on a particulate consisting of a zeolite and a porous inorganic oxide and/or a clay mineral, excepting the zeolite, wherein a supporting amount of V is 1,000-20,000 mass ppm in V metal conversion, at least a part of V forms a polynuclear complex salt, the acid content is 20-450μmol/g and the micropore surface area is 30-150 m2/g. The production method of the low-sulfur gasoline uses the catalyst. COPYRIGHT: (C)2007,JPO&INPIT
