| 摘 要： | 制备了N-丁基吡啶四氟硼酸盐离子液体(BPy]BF4), 考察了其对含有噻吩和二苯并噻吩的模型油萃取脱硫的效果. 在此基础上以离子液体为萃取剂, 以过氧化氢(质量分数30%)为氧化剂, 研究了其对模型油进行萃取-氧化脱硫的效果, 结果表明, 当V(BPy]BF4)∶V(Oil)∶V(H2O2)=1∶1∶0.4时, 在55 ℃下进行萃取-氧化脱硫30 min, 噻吩和二苯并噻吩的脱硫率分别达到78.5%和84.3%; 将该萃取-氧化体系应用于实际汽油体系, 脱硫率达到56.3%; 对使用过的离子液体进行再生处理, 重复使用4次脱硫率无明显变化.

| Abstract: | The N-butyl-pyridinium-based ionic liquid BPy]BF_4 was prepared. The effect of extraction desulfurization on model oil with thiophene and DBT was investigated. Ionic liquid and hydrogen peroxide were tested in extraction-oxidation desulfurization to model oil. The results show that ionic liquid BPy]BF_4 is effective to remove sulfur content in model oil. The best conditions are V(IL): V(Oil): V(H_2O_2) = 1:1:0.4,55 ℃and 30 min. The ratios of desulfurization to thiophene and DBT reached 78.5% and 84.3%, respectively, which were much higher than extraction desulfurization only with ionic liquid. In this condition, effect of desulfurization on FCC gasoline was also investigated, the desulfurization was 56.3%. Regenerate ionic liquid can be used more than 4 times. |
