FIELD: chemistry. n SUBSTANCE: method of preparing a catalyst is described, that comprises impregnating a carrier, which contains, wt %: aluminium borate Al 3 BO 6 with the structure of norbergite - 5.0-25.0; sodium - not more than 0.03; γ-Al 2 O 3 - the rest; aqueous solution of a bimetallic complex compound [Co (H 2 O) 2 (C 6 H 5 O 7 )] 2 [Mo 4 O 11 (C 6 H 5 O 7 ) 2 ] followed by drying. The proportions of the components are used such that the resulting catalyst contains, wt %: [Co (H 2 O) 2 (C 6 H 5 O 7 )] 2 [Mo 4 O 11 (C 6 H 5 O 7 ) 2 ] 33.0-43.0; carrier - the rest. The carrier contains, wt %: aluminium borate Al 3 BO 6 with the structure of norbergite - 5.0-25.0; sodium - not more than 0.03; γ-Al 2 O 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 m 2 /g, a pore volume of 0.35-0.65 cm 3 /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. n EFFECT: producing a catalyst having maximum activity in target reactions occurring when hydrocarbon material is hydrotreated. n 5 cl, 7 ex, 1 tbl |
