REGENERATED HYDROPROCESSING CATALYST Russian patent published in 2018 - IPC B01J23/94 B01J23/882 B01J27/53 B01J27/19 

FIELD: technological processes.

SUBSTANCE: invention relates to a regenerated hydroprocessing catalyst for diesel fuel. Regenerated hydroprocessing catalyst is described having a pore volume of 0.3–0.8 ml/g, specific surface area of 150–280 m²/g, average pore diameter of 6–15 nm, which includes molybdenum, cobalt, phosphorus, sulfur and carrier, while molybdenum, cobalt and phosphorus are contained in the catalyst in the form of a mixture of complex compounds. Co(C₆H₆O₇), H₄[Mo₄(C₆H₅O₇)₂O₁₁], H₃[Co(OH)₆Mo₆O₁₈], H₆[P₂Mo₅O₂₃], sulfur is contained in the form of sulfate anion SO₄^2-, phosphorus is contained in the form of the phosphate anion RO₄^3- in the following concentrations, wt. %: Co(C₆H₆O₇) – 6.3–13.0; H4[Mo4(C₆H₅O₇)₂O₁₁] – 8.6–11.2; H₃[Co(OH)₆Mo₆O₁₈] – 6.2–7.7; H₆[P₂Mo₅O₂₃] – 4.0–10.2; SO₄^2- – 0.7–2.6; PO₄^3- – 0.5–4.4; carrier – the rest.

EFFECT: technical result consists in obtaining an improved regenerated hydroprocessing catalyst.
