METHOD OF PRODUCING SELECTIVE HYDROFINING CATALYST OF OLEFIN-CONTAINING HYDROCARBON MATERIAL

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method of producing a selective hydrofining catalyst of an olefin-containing hydrocarbon feedstock. Method involves impregnating porous support in moisture capacity with solutions K₂MoS₄ and organic cobalt complexonate containing at least two oxygen atoms and at least two carbon atoms in an organic solvent. Content in calcined at 550 °C the catalyst contains the following components, in wt%: Mo 5–12, Co 0.5–4, K 3–10 and the rest is a carrier.;EFFECT: obtaining a selective catalyst having high hydrodesulphurisation (HDS) and low hydrogenating (HIDO) functions, which enables selective hydrofining of olefin-containing hydrocarbon raw material to obtain a product which satisfies requirements for commercial gasoline components with minimum loss of octane number.;7 cl, 2 tbl, 10 ex
