FIELD: liquid fuel production processes. ^ SUBSTANCE: invention relates to production of fuel fractions, in particular straight-run gasoline fractions. Process of producing fuel fractions comprises isolation and compounding of straight-run gasoline fractions with antiknock agents, high-octane components, or mixture thereof. Gas condensate sample is distilled into narrow gasoline fractions with boiling ranges from initial boiling point to 85/180°C, after which their physicochemical properties as well as potential yield and knock resistance are determined. Knock factor characterizing gradient of yield (wt %) per one point of octane number according to motor method, correlation coefficient characterizing dynamics of changes in knock factor of gasoline fractions, and conditions for choice of desired straight-run gasoline fraction for compounding and production of commercial gasoline are further determined. Desired straight-run gasoline fraction is then recovered and formulation of binary antiknock agents for this fraction is established, whereupon the fraction is sent to compounding unit for production of A-76 gasoline. ^ EFFECT: increased knock resistance of straight-run gasoline fractions to standard level owing to provided optimal combination of physicochemical properties of fraction and chemical properties of antiknock agents. ^ 3 tbl |
