FIELD: chemistry.

SUBSTANCE: invention relates to zeolite-containing catalysts. Described is a zeolite-containing catalyst for converting a straight-run gasoline fraction to a high-octane gasoline component with low benzene content, which contains iron-aluminosilicate with H-ZSM-5 type high-silica zeolite structure with silica modulus SiO₂/Al₂O₃=55, SiO₂/Fe₂O₃=540, in amount of 97.0-99.0 wt % and a modifying component which is at least one of the following: Cu, Zn, Ni, Mo, in amount of 1.0-3.0 wt %; which is introduced into iron-aluminosilicate in form of metal nanopowder; the catalyst is formed during thermal treatment. Described is a method of producing said catalyst, characterised by that the H-ZSM-5 type iron-aluminosilicate with silica modulus SiO₂/Al₂O₃=55, SiO₂/Fe₂O₃=540 is obtained via hydrothermal crystallisation of the reaction mixture at 120-180°C for 1-4 days, which contains sources of silicon oxide, aluminium oxide, iron oxide, alkali metal oxide, hexamethylene diamine and water; with further mixing of the iron-aluminosilicate with nanopowder of metals selected from Cu, Zn, Ni, Mo, obtained by electric blasting the wire of the metal in a medium of argon, followed by mechanochemical treatment, moulding the catalyst mass, drying and calcination. Described is a method of converting a straight-run gasoline fraction to a high-octane gasoline component with low content of benzene in the presence of the catalyst described above at 350-425°C, volume rate of 1.0-2.0 h^-1 and pressure 0.1-1.0 MPa.

EFFECT: high activity and selectivity of the catalyst.
