FIELD: chemistry.

SUBSTANCE: method of preparing a catalyst is described, that comprises impregnating a carrier, which contains, wt %: aluminium borate Al₃BO₆ with the structure of norbergite - 5.0-25.0; sodium - not more than 0.03; γ-Al₂O₃ - the rest; aqueous solution of a bimetallic complex compound [Co (H₂O)₂(C₆H₅O₇)]₂[Mo₄O₁₁(C₆H₅O₇)₂] followed by drying. The proportions of the components are used such that the resulting catalyst contains, wt %: [Co (H₂O)₂(C₆H₅O₇)]₂[Mo₄O₁₁(C₆H₅O₇)₂] 33.0-43.0; carrier - the rest. The carrier contains, wt %: aluminium borate Al₃BO₆ with the structure of norbergite - 5.0-25.0; sodium - not more than 0.03; γ-Al₂O_{3 -} the rest. The carrier impregnation is used by a moisture capacity or from a solution excess. After impregnation, the catalyst is dried in air at the temperature of 100-200C°. The used conditions of preparation provide a catalyst having a specific surface of 130-180 m²/g, a pore volume of 0.35-0.65 cm³/g, the average pore diameter is 7-12 nm and is particles with a section in the form of a 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 maximum activity in target reactions occurring when hydrocarbon material is hydrotreated.
