According to the method, an initial raw material is fed into two in-series-connected reaction units, a first unit and a second unit, with zeolite catalysts based on a pentasil group; the reaction units are distinguished through the conditions for converting the hydrocarbons to aromatic hydrocarbons; a mixture obtained following the reaction units is separated into a liquid fraction and a gas fraction, and the gas fraction is fed to the inlet of the first and second reaction unit. The method is characterized in that the gas fraction obtained following the reaction units is separated into a hydrogen-containing gas and into a broad fraction of light hydrocarbons, containing olefins, and in that the hydrogen-containing gas is fed into an oxygenate synthesis unit, in that the resultant oxygenates are fed to the inlet of the first and second reaction unit, and in that the broad fraction of light hydrocarbons, containing olefins, is fed to the inlet of the first reaction unit. The use of the present invention allows for increasing the efficiency of producing concentrates of aromatic hydrocarbons and for increasing selectivity in regard to alkyl benzoles, and specifically xylenes.

摘要： The invention relates to hydrocarbon feedstock processing technology, in particular, to catalysts and technology for aromatization of C 3 -C 4 hydrocarbon gases, light low-octane hydrocarbon fractions and oxygen-containing compounds (C 1 -C 3 aliphatic alcohols), as well as mixtures thereof resulting in producing an aromatic hydrocarbon concentrate (AHCC). The catalyst comprises a mechanical mixture of 2 zeolites, one of which is characterized by the silica/alumina ratio SiO 2 /Al 2 O 3 =20, pre-treated with an aqueous alkali solution and modified with oxides of rare-earth elements used in the amount from 0.5 to 2.0 wt% based on the weight of the first zeolite. The second zeolite is characterized by the silica/alumina ratio SiO 2 /Al 2 O 3 =82, comprises sodium oxide residual amounts of 0.04 wt% based on the weight of the second zeolite, and is modified with magnesium oxide in the amount from 0.5 to 5.0 wt% based on the weight of the second zeolite. Furthermore, the zeolites are used in the weight ratio from 1.7:1 to 2.8:1, wherein a binder comprises at least silicon oxide and is used in the amount from 20 to 25 wt% based on the weight of the catalyst. The process is carried out using the proposed catalyst in an isothermal reactor without recirculation of gases from a separation stage, by contacting a fixed catalyst bed with a gaseous feedstock, which was evaporated and heated in a preheater. The technical result consists in achieving a higher aromatic hydrocarbon yield while ensuring almost complete conversion of the HC feedstock and oxygenates, an increased selectivity with respect to forming xylols as part of an AHCC, while simultaneously simplifying the technological setup of the process by virtue of using a reduced (inter alia, atmospheric) pressure.
