CATALYST, METHOD OF THEREOF PREPARATION AND PROCESS OF SELECTIVE HYDRODESULPHURISATION OF OLEFIN-CONTAINING HYDROCARBON RAW MATERIAL Russian patent published in 2015 - IPC B01J23/74 B01J23/78 B01J23/85 B01J31/04 B01J35/10 B01J37/02 C10G45/08 

FIELD: chemistry.

SUBSTANCE: invention relates to catalyst of selective hydrodesulphurisation of olefin-containing hydrocarbon raw material. Said catalyst consists of compounds of metals Co or Ni, Mo and Na or K, applied on carrier. Claimed catalyst contains bimetal complex compound of metals Co or Ni, Mo and Na or K, carboxylic acid, containing, at least, one carboxyl group and 1-20 carbon atoms; it has specific surface 180-350 m²/g, volume of pores 0.3-1.1 cm³/g, average pore diameter 5.5-11.0 nm. Invention relates to method of preparing claimed catalyst, as well as to process of selective hydrodesulphurisation with its application.

EFFECT: claimed catalyst makes it possible to obtain petrol with ultralow content of sulphur and preservation of value of its octane number at initial level.
