FLUID CATALYTIC CRACKING CATALYST, ITS PRODUCING METHOD AND METHOD FOR PRODUCING LOW-SULFUR CATALYTICALLY CRACKED GASOLINE

摘要

PROBLEM TO BE SOLVED: To provide a fluid catalytic cracking catalyst which has a high desulfurization rate and can restrain the generation of carbon monoxide (CO) in a regeneration column and to provide a method for producing the fluid catalytic cracking catalyst and a method for producing low-sulfur catalytically cracked gasoline. SOLUTION: The fluid catalytic cracking catalyst is produced by depositing vanadium on a granular substance composed of zeolite, a porous inorganic oxide other than zeolite and/or a clay mineral and is characterized in that a sulfate radical exists on the fluid catalytic cracking catalyst together with the deposited vanadium, the deposited amount of vanadium is 500-20,000 mass ppm in terms of vanadium metal, the acid content is 20-450μmol/g and the surface area of macropores is 30-150 m2/g. The method for producing the fluid catalytic cracking catalyst and the method for producing low-sulfur gasoline by using the fluid catalytic cracking catalyst are provided.
