FIELD: technological processes. ^ SUBSTANCE: invention relates to organic chemistry and catalysis. Described is a catalyst for producing high-octane gasoline with low content of benzene and durene, characterised by that it contains a mechanical mixture of pentasil-type zeolite with silica modulus SiO2/Al2O3=18-25, which does not contain modifiers, is first treated with an aqueous solution of an alkali or a pentasil-type zeolite with silica modulus SiO2/Al2O3=70-90, modified with magnesium oxide in amount of 0.5-3.0 wt %, taken in ratio ranging from 1/1 to 1/10, as well as binder in amount of 20-25% of the weight of the catalyst. Described also is a method of producing high-octane gasoline with low content of benzene and durene in which the catalyst described above is heated in an isothermal reactor with heat pipes to temperature 280-320C; the process of bringing the raw material into contact with the catalyst heated in the isothermal reactor with heat pipes takes place at pressure 0.1-1 MPa while feeding the raw material into the reactor with bulk speed of 1-5 h-1 (for liquid) and an inert gas with bulk speed of 1000-10000 h-1 after evaporation of the raw material in a pre-heater. ^ EFFECT: obtaining a catalyst which enables to obtain high-octane gasoline with low content of benzene and durene. ^ 12 cl, 3 tbl, 2 dwg, 10 ex |
