FIELD: oil and gas industry.
SUBSTANCE: invention refers to a method and a catalyst-catalytic composition for selective olefin-containing naphtha desulphurisation. There is disclosed a desulphurising catalytic laminate comprising a core and an outer layer attached to the core and containing refractory inorganic oxide with at least one dispersed metal component chosen of the group including cobalt, nickel, molybdenum and tungsten. There is disclosed a desulphurisation method involving contacting of olefin-containing naphtha with said catalytic laminate in a desulphurisation zone and medium to produce low sulphur naphtha flow.
EFFECT: higher desulphurising selectivity of the catalyst with maintaining of high olefin content in the prepared desulphurised naphtha.
