Abstract：
 The present invention uses polyglycol 400 as desulfurizing solvent to make multi-stage countercurrent extraction of gasoline. The mass ratio of extracting agent and gasoline is 1-3.5:1. Extracting temp. is 20-70 deg.C. Extracting time is 10-50 min. and constant temperature standing time is 10-30 min. Then. the gasoline phase taken out is the desulfurized gasoline. Said invented solvent possesses the advantages of high desulfurizing efficiency, less toxicity, low mutual solubility with gasoline, simple and convenient for recovering solvent. As compared with hydrogenation process said invented extraction process features small equipoment investment, low cost and simple operation. The loss in octane number of the treated gasoline is small.
