HYDROCRACKING CATALYST FOR HYDROCARBON OIL, METHOD FOR PRODUCING THE SAME, AND HYDROCRACKING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hydrocracking catalyst which makes it easy to diffuse heavy hydrocarbon oils such as VGO, DAO and the like into mesopores, is improved in a cracking activity and makes it possible to obtain a middle distillate at high yield as compared with the conventional catalyst including, as a carrier, the zeolite comprising titanium or zirconium fine particles carried thereon.

SOLUTION: There is provided a hydrocracking catalyst for hydrocarbon oils prepared by a hydrogenative metal component supported by a carrier including an ultrastable Y-type zeolite. The ultrastable Y-type zeolite is a framework-substituted zeolite-1 prepared by replacing a part of aluminum atom forming a zeolite framework with zirconium atoms and/or hafnium atoms.
