FIELD: technological processes.

SUBSTANCE: invention relates to a process for the preparation of a hydrotreating catalyst for a hydrocarbon feedstock comprising molybdenum, cobalt, boron and aluminum compounds. catalyst is prepared by impregnating a carrier which contains, by mass. %: aluminum borate Al₃BO₆ with a structure of norbergite – 5.0–25.0; sodium – no more than the 0.03; γ-Al₂O₃ – the rest, aqueous solution simultaneously containing a bimetallic complex compound [Co(H₂O)₂(C₆H₅O₇)]₂[Mo₄O₁₁(C₆H₅O₇)₂] and boric acid, followed by drying, while the concentrations of the components of the solution are such as to provide a catalyst that contains, by weight: [Co(H₂O)₂(C₆H₅O₇)]₂[Mo₄O₁₁(C₆H₅O₇)₂] 33.0–43.0; boron in the form of surface compounds characterized by absorption bands 930–1,040, 1,230, 1,385–1,450 and 3,695 cm^-1 in IR spectra – 0.4–1.6; carrier – the rest.

EFFECT: technical result consists in the preparation of a catalyst having the maximum activity in the target desulfurization and de-oxidation reactions occurring during the hydrotreatment of the hydrocarbon feedstock.
