摘　　要：建立一种通过聚合离子液体膜材料进行燃油深度脱硫的方法。本文采用1-烯丙基-3-乙烯基咪唑氯盐(AVIM)Cl为单体,以偶氮二异丁腈(AIBN)为引发剂,以N,N-二甲基甲酰胺(DMF)为溶剂,进行(AVIM)Cl单体自由基均聚反应,合成PILs固体膜材料,研究了引发剂用量对膜结构及燃油脱硫性能的影响。结果表明:聚合温度在60℃下,引发剂用量在5‰时,脱硫效果最佳,模拟燃油中硫含量从800ppm降低到438ppm,一次脱除率达到45.2%。A method for deep desulfurization of fuel oil by polymerizing ionic liquid membrane material was proposed. In this paper, 1-allyl-3-vinylimidazolium chloride (AVIM) Cl was used as monomer and azobisisobutyronitrile (AIBN) as initiator, N, N-dimethylformamide (DMF) as the solvent,PILs were synthesized by (AVIM) Cl monomer free radical homopolymerization, and the influence of the amount of initiator on membrane structure and fuel desulfurization performance was studied. The results showed that the optimum sulfur removal efficiency was obtained when the polymerization temperature was 60 ℃ and the amount of initiator was 5 ‰, the sulfur content in simulated fuel was reduced from 800 ppm to 438 ppm,and the removal rate was 45.2%.
