摘　　要：通过实验室合成N-甲基咪唑溴化物、1丁-基-3-甲基咪唑四氟硼酸盐、Zn[CO(NH3)2]3Cl2、Zn[C6H11NO]3Cl2和磷酸酯类等5种离子液体,采用氧化-萃取法对燃料油进行脱硫研究。结果表明:磷酸酯类离子液体的脱硫效果相对较好,对青海直馏柴油进行氧化-萃取脱硫,可使精制油硫含量从1 425μg/g降到676μg/g,脱硫率达52.6%;用于川西北高含硫凝析油及山东滨化直馏汽油脱硫,脱硫率仍能达到50%以上。Five kinds of ionic liquids,such as the N-methyl imidazole bromide,1-butyl-3-methylimidazole four fluoborate,Zn3Cl2,Zn3Cl2 and the phosphoric acid ester are synthesized through the laboratory.The oxidized-extraction method is used to conduct the desulphurization research to the bunker oil.The result indicates that the phosphoric acid ester ionic liquid desulphurization effect is relative better.The oxidized-extract desulphurization is carried on to the Qinghai straight-run diesel oil which may cause the sulfur content of the fine oil fall from 1 425 μg/g to 676 μg/g,the desulphurization rate reaches 52.6%.For high sulfur gas condensate in northwest Sichuan and Binhua,Shandong straightrun gasoline desulphurization,desulphurization rate is still above 50%.
