FIELD: chemistry.

SUBSTANCE: method of preparing catalyst for purification of hydrocarbon raw material includes into composition cobalt, nickel, molybdenum, aluminium and silicon. Two bimetal complex compounds [Co(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] and [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂], where L is partly deprotonated form of citric acid C₆H₆O₇; x=0 or 2; y=0 or 1, are simultaneously applied on carrier, containing aluminium oxide and amorphous alumosilicate. After that, catalyst is dried with obtaining catalyst, containing components in the following concentrations, wt %: in total [Co(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] and [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] - 24.5-39.0; including [Co(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] - 6.2-29.5; [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] - 6.2-29.5; amorphous alumosilicate - 5.9-37.8; γ-Al₂O₃ - the remaining part. It corresponds to content in annealed at 550°C catalyst, wt %: MoO₃ - 14.0-24.0; in total CoO+NiO - 3.6-6.0; including CoO - 0.9-4.5; NiO - 0.9-4.5; amorphous alumosilicate- 6.7-42.0; Al₂O_{3 -} the remaining part.

EFFECT: method makes it possible to obtain catalyst, which has maximal activity in target reactions, taking place in the process of hydropurification of hydrocarbon raw material, and provides obtaining petroleum products with low content of sulphur.
