FIELD: chemistry.

SUBSTANCE: invention relates to hydrotreating catalysts for producing diesel fuel with low sulfur content. Hydrotreating catalyst of diesel fuel contains compounds of cobalt, molybdenum, phosphorus and a carrier. Catalyst contains, wt%: [Co(H₂O)₂(C₆H₅O₇)]₂[Mo₄O₁₁(C₆H₅O₇)₂] – 7.7–32.0; Co₂[H₂P₂Mo₅O₂₃] – 11.1–29.0; carrier – the rest. Carrier contains, wt%: silicon dioxide SiO₂, which is an amorphous phase and having a particle size of 3–20 nm, – 2.0–20.0, aluminum borate Al₃BO₆ with a norgerite structure – 5.0–25.0, γ-Al₂O₃ is the rest. Catalyst has specific surface area of 120–180 m²/g, pore volume of 0.30-0.50 cm³/g, average pore diameter of 7–12 nm and represents particles with cross-section, trefoil or quatrefoil with diameter of described circumference 1.0–1.6 mm and length up to 20 mm.

EFFECT: catalyst has high desulphurisation and denitriding activity.
