CATALYST FOR COMBINED HYDROFINING OF MIXTURE OF VEGETABLE AND PETROLEUM HYDROCARBON MATERIAL AND METHOD FOR PREPARATION THEREOF Russian patent published in 2019 - IPC B01J23/88 B01J23/882 B01J23/883 B01J21/04 B01J21/12 B01J37/02 B82Y99/00 C10G45/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst for combined hydrofining of a mixture of vegetable and petroleum hydrocarbon material. This catalyst includes cobalt, nickel, molybdenum and aluminium oxide, wherein it contains in a state calcined at 550 °C: Mo - 9.0–15.0 wt. %, Co - 0.5–3.5 wt. % and Ni is 0.5–3.5 wt. %; the rest is a porous support with carbon content of 0–5 wt. %; catalyst has specific surface area of 100–250 m²/g, specific pore volume of 0.3–1.1 cm³/g, average pore diameter of 4.0–10.0 nm. Method of preparing said catalyst comprises impregnating a carrier on a moisture capacity followed by drying, wherein the vacuum-containing support containing aluminium oxide is impregnated once with an aqueous solution of precursors of active components, containing molybdenum heteropolyacid, nickel or cobalt complexonate with carboxylic acid.

EFFECT: technical result is increased activity and stability of catalyst in process of combined hydrofining mixture of vegetable and petroleum hydrocarbon material.
