METHOD OF HYDROFINING HYDROCARBON MATERIAL Russian patent published in 2014 - IPC C10G45/08 B01J23/882 B01J23/883 

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^-1, volume ratio hydrogen/material of 300-500 m³/m³ in the presence of a heterogeneous catalyst containing cobalt, nickel and molybdenum in the form of bimetallic complex compounds [Co(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] and [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂], where L is a partially deprotonated form of citric acid C₆H₆O₇; x=0 or 2; y=0 or 1; silicon in the form of amorphous aluminosilicate, aluminium in the form of γ-Al₂O₃ and amorphous aluminosilicate, wherein the components are 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 aluminosilicate - 5.9-37.8; γ-Al₂O₃ - the balance, which corresponds to the following content in a catalyst calcined at 550°C, wt %: MoO₃ - 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; Al₂O₃ - 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.
