FIELD: chemistry.SUBSTANCE: invention relates to a method of manufacturing waxy Diesel fuel by hydrogenating processing of crude oil in the presence of a catalysts at higher temperatures and pressure, and further rectification of hydrogenisate with the separation of light and heavy Diesel fractions, which are further mixed, where as crude oil used is a mixture of gasoil of direct distillation of crude oil and a gasoline fraction of delayed coking, in a ratio from 95:5 wt % to 70:30 wt %, which is successively subjected to hydropurification, catalytic hydrodeparaffinisation and additional hydropurification, with a volume of the catalysts from the entire charge constituting: of hydropurification 45-65 wt %, catalytic hydrodeparaffinisation - 20-35 wt %, additional hydropurification - 10-30 wt %.EFFECT: method makes it possible to extend raw material resources for the production of deficit waxy Diesel for land transport, exploited under conditions of cold and Arctic climate, due to inclusion into the composition of wide gasoline fraction of delayed coking.3 cl, 3 ex |
