Abstract
An FCC catalyst which not only deactivates catalyst poison metals, such as nickel, vanadium and the like, in feedstock oils, inhibits the generation of hydrogen or coke, has excellent cracking activity and bottom oil-treating ability, and can yield a gasoline and LCO fraction in high yields, but also retains the performances on a high level over long and has an improved catalyst life; and an FCC method using the catalyst. The FCC catalyst has a compound of a bivalent metal or of bivalent and trivalent metals showing an XRD pattern of a carbonate of the bivalent metal; an inorganic oxide matrix and the compound dispersed therein; or an inorganic oxide matrix and the compound dispersed therein together with a crystalline aluminosilicate zeolite, and relates to an FCC method in which at least one of the catalysts are used in combination with an FCC catalyst obtained by evenly dispersing a crystalline aluminosilicate zeolite in an inorganic oxide matrix.
