英文摘要：

The catalytic oxidation production technology of low sulfur gasoline was proposed with H2O2 as oxidant. The effects of the catalyst system,oxidation and extraction conditions on desulfurization were studied. The experimental results show that under the conditions of H2O2 0.1 mL as oxidant,tungstic acid 0.01 g as catalyst,anhydrous ethanol 0.08 mL as co-catalyst,oxidation at 30 ℃ for 30 min,and by using the mixture of dimethyl formamide （DMF） and furfural with the volume ratio of 4 as the extractant,extraction at 20 ℃ for 15 min,the volume ratio 1 of solvent to oil,the sulfur mass concentration in gasoline is reduced from 407.1 mg/L to 22.1 mg/L,and the desulphurization rate reaches 94.6%.
