CRUDE HYDROCARBONS HYDRO-CRACKING METHOD Russian patent published in 2017 - IPC B01J37/08 B01J31/34 B01J31/22 B01J31/18 C10G45/08 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the hydro-cracking process in which the high boiling crude hydrocarbons is converted at the temperature of 360-440°C, pressure 6-20 MPa, the raw materials mass consumption 0.5-1.5 h^-1, the volume ratio of hydrogen to the raw material is 800-2000 nm³/m³ in the presence of the catalyst, containing nickel and tungsten in the form of bimetallic complex compounds of Ni (NH₄)_x[H_yW₂O₅(C₆H₅O₇)₂], where: C₆H₅O₇ - partially deprotonated form of citric acid; x = 0, 1 or 2; y = 2-x; silicon in the form of the amorphous aluminosilicate, aluminium in the form γ-Al₂O₃. The components in the catalyst are contained in the following concentrations, wt %: [Ni (NH₄)_x[H_yW₂O₅(C₆H₅O₇)₂] - 32.6-39.6, amorphous aluminosilicate - 30.2-47.2; γ-Al₂O₃ the rest, which corresponds to the content of the calcined catalyst at 550C°, wt %: WO₃ - 19.3-24.2, NiO - 3.0-3.8, amorphous aluminosilicate - 36.0-54.4; γ-Al₂O₃ - the rest.

EFFECT: high yield of middle-distillate fractions.
