FIELD: chemistry.

SUBSTANCE: invention relates to a method of preparing a catalyst for hydrocracking hydrocarbon material, including nickel, molybdenum, aluminium and silicon. Method involves preparation of a granular support, containing aluminium oxide and 50–80 wt% amorphous aluminium silicate with weight ratio Si/Al from 0.6 to 0.85, application on produced granulated support of bimetallic complexes [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂], where L is a partially deprotonated form of citric acid C₆H₅O₇; x = 0 or 2; y = 0 or 1, drying catalyst at temperature 100–250 °C. Components in obtained catalyst are 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 annealed 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: technical result is use of a catalyst in hydrocracking which is prepared using disclosed method, ensures production of diesel fraction with high output.
