摘要: 以H2O2 -CH3 COOH 为氧化剂, N , N -二甲基甲酰胺为萃取剂, 在微波作用下对柴油进行脱硫实
验。结果表明, 在复合溶剂用量为理论用量的12 倍, 剂油体积比为0.25 ∶1, 辐射压力为0 .4 MPa 、恒压辐射时间为
6 min , 辐射功率375 W , 萃取剂与油体积比为1 ∶1, 静置时间为10 min 条件下, 油品的脱硫率达到88 .2 %。与其它
氧化脱硫法相比, 脱硫率提高26 %~ 42 %, 氧化剂用量减少20%~ 50%

Abstract: The sulfur - bearing organics in diesel oil was oxidized using H2O2 - CH3COOH systems via microwave irradiation,then the oxidized organic sulfur compounds (sulfones) were extracted by N,N - dimethyl formamide. Experimental results show that the removal efficiency of sulfur compounds is up to 88.2% in the following conditions:the dosage of the oxidant is 12 times as much as that of theoretical, the volume ratio of solvent-to-oil is 0.25∶1, the pressure is 0.4 MPa, the radiant time on the constant pressure is 6 min, the microwave power is 375 W,the volume ratio of extractant-to- oil is 0.25∶1, the standing time is 10 min. Compared with other methods on oxidative desulfurization, the removal efficiency of sulfur can increase 26%~42% and the dosage of the oxidant reduce 20%~50%.
