CATALYST FOR HYDROTREATING HYDROCARBON RAW MATERIALS Russian patent published in 2017 - IPC B01J23/00 B01J23/882 B01J32/00 B01J21/02 B01J21/04 C10G45/08 

FIELD: chemistry.

SUBSTANCE: catalyst is described containing, wt %: [Co(H₂O)₂(C₆H₅O₇)]₂[Mo₄O₁₁(C₆H₅O₇)₂] 33.0-43.0%; carrier - the rest; the carrier comprising, wt %: aluminium borate Al₃BO₆ with the structure of norbergite - 5.0-25.0; sodium - not more than 0.03; γ-Al₂O₃ - the rest. The aluminium borate Al₃BO₆ with the structure of norbergite is a particle with dimensions of 10 to 200 nm, characterized by interplanar distances of 3.2 and 2.8 A, with an angle between them of 53.8°. The catalyst has a specific surface area of 130-180 m²/g, a pore volume of 0.35-0.65 cm³/g, the average pore diameter is 7-12 nm and is particles with a section in the form of a circle, trefoil or quatrefoil with a diameter of the circumscribed circle of 1.0-1.6 mm and the length of up to 20 mm. After sulphiding by the known techniques, the catalyst contains, wt %: Mo - 10.0-14.0; Co - 3.0-4.3; S = 6.7-9.4; carrier - the rest.

EFFECT: producing a catalyst having maximum activity in target reactions occurring when hydrocarbon material is hydrotreated.
