METHOD FOR PRODUCTION OF ENVIRONMENTALLY SAFE DIESEL FUEL Russian patent published in 2000 - IPC

Abstract RU 2148070 C1

FIELD: petroleum processing. SUBSTANCE: aromatic hydrocarbons and organosulfur compounds are removed from hydrofined diesel fraction via multistage countercurrent extraction at 30-50 C using heterogeneous mixture of solvents: acetonitrile or acetonitrile with 2-5 wt.% water and pentane at weight ratios of acetonitrile and pentane to raw material (3- 5):1 and (0.5-1.5): 1, respectively. EFFECT: achieved environmental safety of fuel. 3 tbl, 2 ex
