摘　　要：利用浸渍法制备了Cu2+/Al2O3、Ni-Mn为主要组分的催化剂,并用其为催化剂、市售0#柴油为对象探讨了等离子体催化氧化-萃取脱硫工艺。结果表明该催化剂的催化效果优于其他催化剂。当电极两端电压为17kV、驱动频率为15kHz、催化剂用量为5%质量分数、氧化时间为20min、萃取剂为甲醇、剂/油体积比为1∶1、萃取时间为15min时,一级脱硫率可达到73.8%。Cu2+/Al2O3 and Ni-Mn catalysts are prepared by impregnation,and its catalytic performance in oxidative desulfurization of 0# diesel fuel is studied.The results show that the catalytic of Ni-Mn is better than the others.The effects of several parameters are investigated.Under the optimal conditions as input voltage of 17 kV,input frequency of 15 kHz,catalyst amount of mass ratio 5%,reaction time of 20 minutes,volumic ratio of extractant to oil of 1∶1,the desulfurization rate can be 73.8%.
