A destructive process of hydroisomerization of straight-run 85–185°C gasoline fraction followed by close fractionation of the products into a high-octane low-boiling (–85°C) isocomponent and a fraction with a final BP of 85°C is proposed. The latter is free of benzene-forming hydrocarbons and is submitted to catalytic reforming under mild conditions. Gasoline with octane number 86 (MM) and containing ~51 wt. % of aromatic hydrocarbons, including less than 0.5 wt. % of benzene, is obtained by compounding the isocomponent and the reformate in 25:75 ratio.
