FIELD: chemistry.

SUBSTANCE: invention relates to methods for preparing hydrotreatment catalysts of petroleum fractions with a boiling point above 360°C for producing raw materials with a low content of sulfur and nitrogen, which is further processed in the hydrocracking process. The method for preparing a catalyst, comprising the carrier impregnation, which comprises, wt %: aluminium borate Al₃BO₆ with the structure of norbergite - 5.0-25.0; sodium - not more than 0.03; -γAl₂O₃ - the rest, with an aqueous solution of a bimetallic complex compound [Ni (H₂O)₂]₂[Mo₄O₁₁(C₆H₅O₇)₂] followed by drying. The catalyst contains, wt %: [Ni (H₂O)₂]₂[Mo₄O₁₁(C₆H₅O₇)₂] 29.0-36.0%; carrier - the rest. The carrier impregnation is used by the moisture capacity or from a solution excess. Impregnation is carried out at the temperature of 20-80°C for 20-60 minutes with occasional stirring. After impregnation, the catalyst is dried in air at the temperature of 100-200°C. The catalyst has specific surface area of 130-180 m²/g, the pore volume of 0.35-0.65 cm³/g, the average pore diameter is 10-15 nm and particles with section in the form of circle, trefoil or quatrefoil with a diameter of the circumscribed circle of 1.0-1.6 mm and the length of up to 20 mm.

EFFECT: producing a catalyst having the maximum activity in the desulfurization and denitrogenation reactions occurring during the hydrotreatment of petroleum fractions with a boiling point above 360 degrees.
