Abstract
A method is proposed for production of environmentally friendly diesel fuel , including five-step countercurrent extraction of aromatic hydrocarbons fr om the hydrofined diesel fraction with dimethylformamide or dimethylacetami de containing 3-5 wt % H2O and pentane followed by regeneration of the extr actants from the extract phase by azeotropic distillation. The process allo ws production of diesel fuel with the content of aromatic hydrocarbons belo w 10 wt %. Another product is a petroleum aromatic solvent like Nefras AR-1 50/330.
