FIELD: chemistry.

SUBSTANCE: invention relates to a method of hydrocracking hydrocarbon material, which comprises converting high-boiling material at temperature 360-440 °C, pressure 6-20 MPa, weight ratio of raw material 0.5-1.5 h^-1, volume ratio hydrogen/material 800-2,000 nm³/m³ in presence of a heterogeneous catalyst. Catalyst used contains nickel and molybdenum in form of bimetallic complex compounds [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂], where L is partially a deprotonated form of citric acid C₆H₆O₇; x=0 or 2; y=0 or 1; silicon in form of amorphous aluminosilicate, aluminium in form of γ-Al₂O₃ and amorphous aluminosilicate, wherein components are contained in following concentrations, wt%: [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] 13.1-23.3, amorphous aluminum silicate - 40.0-61.3; γ-Al₂O₃ - balance, which corresponds to content in catalyst calcined at 550 °C, wt%: MoO₃ - 7.0-13.0, NiO - 1.8-3.4, amorphous aluminum silicate - 43.1-66.9; γ-Al₂O₃ - balance.

EFFECT: proposed method enables to obtain middle distillates with low residual content of sulphur.
