FIELD: oil refining industry.

SUBSTANCE: the invention relates to hydrocracking catalysts of hydrocarbons. A hydrocracking catalyst of hydrocarbons is described, containing, by weight %: WO₃ – 20.2-30.3, NiO – 4.6-6.9, zeolite Y with a silicon-enriched surface, 0.7-1.7, zeolite Y with an aluminum-enriched surface, 2.2-3.5, amorphous aluminosilicate 27.6–33.8, γ-Al₂O₃ – the rest; the carrier contains simultaneously two zeolites Y having different concentrations of acid centers and the distribution of aluminum between the surface of the crystals and their volume; as the first zeolite, the carrier contains zeolite Y with a higher concentration of acid centers and with a ratio of surface to volume concentration of silicon to aluminum Si/Al = 1.2-2.1; as a second zeolite, the carrier contains zeolite Y with a lower concentration of acid centers and a ratio of the surface to volume concentration of silicon to aluminum Si/Al = 0.7-0.9, while nickel and tungsten are contained in the form of highly dispersed oxides obtained from bimetallic complex compounds Ni(NH₄)_a[H_bW₂O₅(C₆H₅O₇)₂], where a = 0, 1 or 2; b = (2-a).

EFFECT: creation of a hydrocracking catalyst with high activity.
