FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of aromatising non-aromatic hydrocarbons contained in a hydrogenated fraction of a C6-C8 pyrolysis condensate. The method involves reaction of starting material with a metal-containing zeolite aromatisation catalyst at high temperature, and is characterised by that the starting material is a hydrogenated fraction of a C6-C8 pyrolysis condensate containing not less than 70 wt % aromatic hydrocarbons and 8-30 wt % non-aromatic hydrocarbons. The aromatisation catalyst used is a zeolite having entrance window diameter 5.1-7.3, having molar ratio of silicon to aluminium equal to 25-140, modified with metals selected from: zinc, gallium, silver, rhodium, platinum, rare-earth elements, as well as combinations thereof. ^ EFFECT: invention increases output of the end product - benzene and reduces output of light hydrocarbon fractions when processing pyrolysis condensate. ^ 7 cl, 42 ex, 4 tbl |
