REGENERATED CATALYST OF HYDRAULIC CLEANING Russian patent published in 2017 - IPC B01J23/94 B01J27/53 C10G45/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a regenerated diesel fuel hydrotreating catalyst that has a pore volume of 0.3-0.8 ml/g, a specific surface area of 150-280 m²/g, an average pore diameter of 6-15 nm, including molybdenum, cobalt, sulfur and a carrier in its composition. In this case, molybdenum and cobalt are contained in the catalyst in the form of a mixture of complex compounds Co(C₆H₆O₇), H₄[Mo₄(C₆H₅O₇)₂O₁₁], H₃[Co(OH)₆Mo₆O₁₈], sulfur is contained in the form of sulfate anion SO₄^2-, in the following concentrations, wt %: Co(C₆H₆O₇) - 5,1-18,0; H₄[Mo₄(C₆H₅O₇)₂O₁₁] - 7,5-15,0; H₃[Co(OH)₆Mo₆O₁₈] - 4,3-19,0; SO₄^2- - 0,5-2,30; the carrier is the rest, while cobalt citrates can be coordinated to molybdenum citrate H₄[Mo₄(C₆H₅O₇)₂O₁₁] and to the 6-molybdocobaltate H₃[Co(OH)₆Mo₆O₁₈].

EFFECT: invention makes it possible to obtain regenerated catalysts whose activity in the hydrotreating of diesel fuel is 100 percent or more of the activity of fresh catalysts.
