Abstract:
The present invention relates to a hydrocracking catalyst for hydrocarbon oil comprising a support containing a framework-substituted zeolite-1 in which zirconium atoms and/or hafnium atoms form a part of a framework of an ultrastable y-type zeolite and a hydrogenative metal component carried thereon and a method for producing the same. The hydrocracking catalyst of the present invention 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 a high yield as compared with catalysts prepared by using zeolite comprising titanium and/or zirconium carried thereon.

Claim (Index 34):
A method for producing a hydrocracking catalyst for the high boiling fraction containing hydrocarbon oil, the hydrocracking catalyst being defined in  claim 21 ,\n wherein the zeolite-1 is obtained by: firing an ultra-stable Y-type zeolite at 500\u00b0 C. to 700\u00b0 C., the ultra-stable Y-type zeolite having a crystal lattice constant falling in a range of 2.430 nm or more and 2.450 nm or less, a specific surface area of 600 to 900 m 2 /g, and a molar ratio of SiO 2  to Al 2 O 3  of 20 to 100; forming a suspension containing the fired ultra-stable Y-type zeolite, the suspension having a liquid/solid mass ratio of 5 to 15; adding inorganic acid or organic acid so that a pH of the above suspension is 1.0 to 2.0, subsequently adding a zirconium compound and/or a hafnium compound and mixing them; and neutralizing the above mixed solution.
