CATALYST FOR HYDROCRACKING HYDROCARBON MATERIAL Russian patent published in 2017 - IPC B01J20/16 B01J21/12 B01J23/883 C10G47/12 

FIELD: chemistry.

SUBSTANCE: invention relates to catalyst for hydro-cracking hydrocarbon raw material, which includes nickel, molybdenum, aluminium and silicon. wherein nickel and molybdenum are contained in form of bimetallic complexes [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂], where L is a partially deprotonated form of citric acid C₆H₅O₇; x = 0 or 2; y = 0 or 1; silicon in form of amorphous aluminium silicate, aluminium in form of γ-Al₂O₃ and amorphous aluminium silicate. Components in catalyst are contained in following concentrations, wt%: [Ni(H₂O)_x(L)_y]₂[Mo₄O₁₁(C₆H₅O₇)₂] – 13.1–23.3, amorphous aluminum silicate – 40.0–61.3; γ-Al₂O₃ – balance, which corresponds to content in catalyst annealed at 550 °C, wt%: MoO₃ – 7.0–13.0, NiO – 1.8–3.4, amorphous aluminum silicate – 43.1–66.9; γ-Al₂O₃ – balance. Weight ratio Si/Al in amorphous aluminium silicate is 0.6–0.85, wherein x-ray diffraction pattern of amorphous aluminium silicates contain a wide peak within range of 16.5–33.5° with maximum at 23.1–23.4°.

EFFECT: technical result is high activity in hydrocracking hydrocarbon material and high selectivity with respect to diesel fraction.
