FIELD: chemistry.SUBSTANCE: invention relates to a method of hydrofining hydrocarbon material to obtain products with low sulphur content. The invention relates to a hydrofining method which comprises converting hydrocarbon material with high sulphur content at 340-375°C, pressure of 3.5-6.0 MPa, mass flow rate of the material of 1.0-1.5 h, volume ratio hydrogen/material of 300-500 m/min the presence of a heterogeneous catalyst containing cobalt, nickel and molybdenum in the form of bimetallic complex compounds [Co(HO)(L)][MoO(CHO)] and [Ni(HO)(L)][MoO(CHO)], where L is a partially deprotonated form of citric acid CHO; x=0 or 2; y=0 or 1; silicon in the form of amorphous aluminosilicate, aluminium in the form of ?-AlOand amorphous aluminosilicate, wherein the components are in the following concentrations, wt %: in total [Co(HO)(L)][MoO(CHO)] and [Ni(HO)(L)][MoO(CHO)] - 24.5-39.0; including [Co(HO)(L)][MoO(CHO)] - 6.2-29.5; [Ni(HO)(L)][MoO(CHO)] - 6.2-29.5; amorphous aluminosilicate - 5.9-37.8; ?-AlO- the balance, which corresponds to the following content in a catalyst calcined at 550°C, wt %: MoO- 14.0-.,0; in total CoO+NiO - 3.6-6.0; including CoO - 0.9-4.5; NiO - 0.9-4.5; amorphous aluminosilicate - 6.7-42.0; AlO- the balance.EFFECT: obtaining oil products with low residual content of sulphur when hydrofining hydrocarbon material in the presence of a catalyst containing bimetallic complexes of Mo, Co, Ni and amorphous aluminosilicate.5 cl, 1 tbl, 8 ex |
