FIELD: technological processes.

SUBSTANCE: invention relates to a process of preparing a catalyst for hydrocracking hydrocarbon material oriented to produce low-sulfur kerosene and diesel fractions. Method comprises preparing a granular carrier containing alumina and 50–70 % by weight of an amorphous aluminum silicate with a Si/Al mass ratio from 0.6 to 0.85, applying bimetallic complex compounds to the obtained granular carrier [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; drying the catalyst at a temperature of 100–250 °C. Components in obtained catalyst are in 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 aluminum silicate – 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 aluminum silicate – 38.3–56.9, γ-Al₂O₃ – rest.

EFFECT: technical result consists in obtaining kerosene and diesel fractions with high yield and low sulfur content.
