FIELD: oil and gas industry.SUBSTANCE: hydrofining method to obtain hydrocarbon compositions includes hydrofining of mixture that contains component (A) - gas oil in quantity from 20 up to 95 wt %; component (A1) - benzene in quantity from 1 up to 40 wt %; component (B) of biologic origin containing fatty acid esters, probably including freed fatty acids; quantity of biologic component is from 4 up to 60 wt %. Moreover all percent ratios are referred to total weight of all components. Hydrocarbon composition (C) has been also claimed; this composition can be used as propellant and/or fuel; it is obtained by hydrofining method; it has cetane number more than 50, density of 820-845 kg/m, content of polyaromatic compositions less than 1 by wt % in regard to total weight of hydrocarbon compound and total content of polyaromatic compositions less than 20 be wt % in regard to total weight of the composition.EFFECT: obtaining hydrocarbon composition with improved low-temperature properties.39 cl, 4 tbl, 2 ex |
