HYDROCARBONS CRUDE HYDROCRAKING CATALYST Russian patent published in 2017 - IPC B01J31/34 B01J31/22 B01J31/18 C10G45/08 

FIELD: oil and gas industry.

SUBSTANCE: catalyst, including nickel, tungsten, aluminium and silicon is described. It contains nickel and tungsten in the form of bimetallic complex compounds of Ni (NH₄)_x[H_yW₂O₅(C₆H₅O₇)₂], where C₆H₅O₇ are 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 of 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. In this case, the weight ratio of Si/Al in the amorphous aluminosilicate is from 0.6 to 0.85, wherein the X-ray diffraction patterns of the amorphous aluminosilicates contain the wide peak in the range 16.5-33.5° with the maximum 23.1-23.4°.

EFFECT: hydrocarbons crude high activity in the hydrocracking and high selectivity with respect to the middle distillate fractions.
