摘要
FIELD: chemical and petrochemical industries. SUBSTANCE: invention presents a method of preparation of the catalyst for hydroupgrading of oil fractions by injection into the alumina carrying agent of the phase-forming promoters from a list of aluminosilicates of amorphous and crystalline type, phosphates of compounds of boron, titanium, zirconium, rare earth elements and active components like NiO and MoO3 and / or WO3 by impregnation of the carrying agent with an aqueous solution of salts Ni and Mo and / or W, provided that the impregnation solution is prepared by mixing of an aqueous solution of nickelous nitrate and an aqueous solution of an ammonium molybdate and / or an ammonium tungstate, pre-stabilized by the strong inorganic acids like hydrogen superoxide, hydrogen peroxide, nitric acid, orthophosphoric acid, or their blends; NiO and MoO3 and / or WO3, or MoO3 and WO3 are brought into the carrying agent by impregnation preferably from solutions with concentration by NiO - 80-200 g/l, by MoO3 - 160-250 g/l, and / or by WO3 160-420 g/l, or by MoO3 and WO3 200-420 g/l. EFFECT: catalysts have high strength and activity in process of hydroupgrading of oil fractions. 2 cl, 4 ex, 2 tbl
