| 摘 要： | 以H2O2-CH3COOH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0．4MPa、恒压辐射时间为6min，辐射功率375W，萃取剂与油体积比为1：1，静置时间为10min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 H2O2- CHaCOOH 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 pr4ssure 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^% |
