FIELD: chemistry.

SUBSTANCE: invention relates to hydrocracking catalysts of raw hydrocarbon deposits for producing low-sulfur kerosene and diesel fractions. Catalyst is described that simultaneously contains molybdenum and tungsten in form of bimetallic complex compounds [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] and Ni(NH₄)_a[H_bW₂O₅(C₆H₅O₇)₂], where: L and C₆H₅O₇ –partially deprotonated form of citric acid; x=0 or 2; y=0 or 1; a=0, 1 or 2; b=2-a; silicon in form of amorphous aluminosilicate, aluminum in form γ-Al₂O₃ and amorphous aluminosilicate, herewith components in the catalyst are in the following concentrations, wt%: [Ni(H₂O)_x(L)_y]₂[MO₄O₁₁(C₆H₅O₇)₂] – 6.2–14.9, Ni(NH₄)_a[H_bW₂O₅(C₆H₅O₇)₂] – 10.2–23.3, amorphous aluminosilicate – 33.4–50.9; γ-Al₂O₃ – rest, which corresponds to the content in calcined catalyst at 550 °C, wt.%: MoO₃ – 3.6–8.4, WO₃ – 5.8–13.5, NiO – 3.1–3.9, amorphous aluminosilicate – 38.3–56.9, γ-Al₂O₃ – rest. In this case, tungsten and molybdenum contained in the catalyst are contained in molar ratio W/(Mo+W) from 0.3 to 0.7.

EFFECT: high activity in hydrocracking hydrocarbon material and high selectivity with respect to diesel fraction.
