减压

The experimental results showed that using ionic liquid Et3NHCl-2AlCl3 under the conditions of an extraction temperature of 40℃, an extraction time of 40 min and an agent/oil ratio of 0.02, the sulfur removal rate was more than 90%. The ionic liquids could be used repeatedly for 4 times and the used ionic liquids could be regenerated by vacuum distillation, about 52.34% of the thiophen was recovered during regeneration.

实验结果表明，选用无水AlCl3与Et3NHCl的摩尔比为2.0的离子液体进行萃取脱硫实验，当萃取时间为40 min、温度为40 ℃、剂油体积比为0.02时，脱硫率可达到90%以上；离子液体不仅可以重复使用4次，而且还可以通过减压蒸馏的方法进行再生，在再生过程中可回收约52.34%的噻吩。
