Hydrocracking catalyst for hydrocarbon oil, method for producing hydrocracking catalyst, and method for hydrocracking hydrocarbon oil with hydrocracking catalyst

A method for producing a hydrocracking catalyst for hydrocarbon oil, the hydrocracking catalyst including a hydrogenative component carried on a support containing a framework-substituted zeolite-1 that contains

• zirconium atoms and/or hafnium atoms substituting a part of aluminum atoms forming a framework of an ultra-stable Y-type zeolite,
• wherein the zeolite-1 is obtained by:
• firing an ultra-stable Y-type zeolite at 500° C. to 700° C., the ultra-stable Y-type zeolite having a crystal lattice constant falling in a range of 2.430 or more and 2.450 nm or less, a specific surface area of 600 to 900 m2/g, and a molar ratio of SiO2 to AI2O3 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, forming a mixture therefrom and neutralizing the said mixture.
