Abstract

This invention provides a method for producing liquid hydrocarbons through catalytic conversion of a synthetic gas (CO+H2), and may be used in the chemical industry, particularly in the production of engine fuels having low concentrations of aromatic hydrocarbons. The purpose of this invention is to improve the productivity of isoparaffin hydrocarbons (i.e. high-octane components of petrol) from a synthetic gas, and to increase the quantities of the components produced. In order to achieve this purpose, the method for producing high-octane components of petrol from a synthetic gas (H2/CO = 1 - 12) comprises the step of heating C1-C11 hydrocarbon mixtures where the C5 fraction is enriched with isoparaffin hydrocarbons, essentially isopentane and 2-methylpentane. This heating is performed at a temperature of 330-400° C, under a pressure of 6-15 MPa and at a raw material volumetric feeding speed of 50-11,000 hr.-1 when in contact with the catalyst. Particles of the catalyst comprise pentazyl-type zeolite and a zinc-chromium catalyst of methanol synthesis based on the atomic ratio Zn/Zn+Cr = 0.6 - 0.8, the concentration of the zeolite component being 10-50 wt. %. According to the present invention, the zeolite component is a crystalline aluminium silicate (SiO¿2?/Al2O3 = 25 - 150) containing 0.2 - 0.5 wt. % of sodium oxide and 0.1 - 5 wt. % of rare-earth oxides, the catalyst being restored at a temperature not exceeding 400° C. Application of this method results in increased productivity and larger quantities of the desired product.
