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 35):
The method for producing a hydrocracking catalyst for the high boiling fraction containing hydrocarbon oil according to  claim 34 , wherein the zeolite-1 is obtained by firing at 500 to 700\u00b0 C., an 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 20 to 100 in terms of SiO 2  to Al 2 O 3 , preparing a suspension having a mass ratio of 5 to 15 in terms of liquid/solid from the above fired ultra-stable Y-type zeolite, adding an inorganic acid or an organic acid thereto 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 a titanium compound and mixing them and then neutralizing the mixed solution.
