| 摘 要： | 利用离子液体EEIM]DEP]的亲水性特点，用水稀释法再生EEIM]DEP]。采用红外光谱对再生EEIM]DEP]进行了表征，比较了不同温度和剂油比下新鲜EEIM]DEP]与再生EEIM]DEP]的萃取效果，采用GC3800气相色谱仪分析了萃取前后硫化物的分布，考察了EEIM]DEP]中水含量对柴油中硫化物萃取效果的影响。结果表明：再生EEIM]DEP]与新鲜EEIM]DEP]的具有相同的结构，对硫化物的萃取效果基本不变。EEIM]DEP]对各类硫化物的选择性次序为C2DBT〉DBT〉C1DBT〉4MDBT〉46DMDBT〉BTs。与新鲜EEIM]DEP]相比，当再生EEIM]DEP]中水含量分别为1％和4％时，脱硫率由不含水时的22.9％分别下降到20.1％和18.8％。

| Abstract: | The used ionic liquid N-ethyl-N-ethyl-imidazolium diethylphosphate(EEIM]DEP]) was recycled by water dilution process based on its hydrophilic property.Both the fresh and regenerated ionic liquid were characterized by IR and the effects of extractive desulfurization were compared in different conditions.The distribution of sulfur-containing compounds in diesel oil before and after extraction were analyzed by GC3800 gas chromatograph.The effect of water contents in EEIM] DEP] on the sulfur removal were al... |
