1. A method of producing a hydrocracking catalyst, in which the method comprises:
adding sodium hydroxide, an aluminum compound, a salt having an anion and a cation, and a silicon compound to an aqueous solution to form an aqueous mixture;
stirring the aqueous mixture;
adding a platinum compound to the aqueous mixture to form a pre-catalyst mixture;
heating the pre-catalyst mixture at from 80° C. to 200° C. for at least 24 hours, thereby crystalizing the pre-catalyst mixture to form the hydrocracking catalyst comprising platinum encapsulated zeolite.
