FIELD: technological processes.

SUBSTANCE: invention relates to a process for hydrotreating a hydrocarbonaceous feedstock comprising converting a hydrocarbon feedstock with a high sulfur and nitrogen content in the presence of a catalyst which contains, by weight: [Co(H₂O)₂(C₆H₅O₇)]₂[Mo₄O₁₁(C₆H₅O₇)₂] 33.0–43.0; boron in the form of surface compounds, 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; carrier comprising, by mass%: aluminum borate Al₃BO₆ with a structure of norbergite – 5.0–25.0; sodium – no more than the 0.03; γ-Al₂O₃ – rest. Invention also relates to a process for hydrotreating a hydrocarbon feed in the presence of a sulphided catalyst that contains, by weight: Mo – 10.0–14.0; Co – 3.0–4.3; S – 6.7–9.4; boron in the form of surface compounds, compounds characterized by absorption bands 930–1,040, 1,230, 1,385–1,450 and 3,695 cm^-1 in IR spectra – 0.5–2.0; carrier – the rest; carrier comprising, by mass. %: aluminum borate Al₃BO₆ with a structure of norbergite – 5.0–25.0; sodium – no more than the 0.03; γ-Al₂O₃ – rest.

EFFECT: technical result is the production of petroleum products with a low residual sulfur and nitrogen content during the hydrotreatment of hydrocarbon feedstocks.
