FIELD: chemistry.
SUBSTANCE: invention relates to catalysts and methods of producing high-octane petrol or aromatic hydrocarbons. A catalyst is described for converting aliphatic C2-C12 hydrocarbons and/or aliphatic oxygen-containing C1-C12 compounds to high-octane petrol or aromatic hydrocarbons, containing pentasil type zeolite, zinc aromatisation promoter, and binder, where the said zeolite is characterised by molar ratio SiO2/A2O3 ranging from 20 to 100, residual content of sodium ions less than 0.1%, aromatisation promoter is introduced using any known method with the following ratio of components: zeolite - 30.0 to 90.0 wt %; zinc - 0.5 to 8.0 wt %; binder - the rest. The catalyst is further treated with ammonium fluoride solution after introduction of zinc. A method is also described for producing this catalyst, involving introduction of pentasil type zeolite and zinc aromatisation promoter into the catalyst, moulding with the binder, subsequent drying and thermal treatment of the catalyst mass, where the zeolite used is pentasil with molar ratio SiO2/AlO3 ranging from 20 to 100 and residual content of sodium ions less than 0.1%. The aromatisation promoter is introduced using any known method in amount ranging from 0.5 to 8.0 wt %, and the obtained zinc-containing catalyst is further treated with aqueous solution of ammonium fluoride. Also described is a method of producing high-octane petrol or aromatic hydrocarbons by converting hydrocarbon material, involving supply of the material and bringing it into contact with heated zeolite-containing catalyst at high pressure with subsequent extraction of reaction products. The hydrocarbon material used is aliphatic C2-C12 hydrocarbons and/or aliphatic oxygen-containing C1-C12 compounds, including as part of main- and by-products of oil, gas and chemical industry, as the catalyst used is the one described above.
EFFECT: design of highly-active and stable catalyst, which provides for processing a wide range of hydrocarbon material.
