Abstract

Abstract: The regeneration of thiophene saturated ionic liquid obtained after desulfurization of gasoline were studied. Cyclopentane was used as the extractant to regenerate the ionic liquid( \[C8MIM\] BF4). The dosage of cyclopentane, extraction time and extraction temperature were examined. The optimal operation condition, where V(ionic liquid)∶V(cyclopentane)=1∶2 at 35 ℃ for 15 min were obtained. Under the optimal condition, the backextraction rate of the ionic liquid can reach 8238%. The recovered ionic liquid was further applied to the desulfurization of model oil, and the desulfurization rate can reach 62.37%. 

Key words: Saturation, Ionic liquid, Backextraction, Regeneration, Desulfurization rate

摘要： 研究了脱硫后噻吩含量达到饱和的离子液体脱硫剂的反萃取回收方法。以环戊烷作为反萃取剂, 考
察了环戊烷体积、反萃时间、反萃温度等因素对离子液体脱硫剂的反萃率的影响。实验结果表明, 最佳反萃条件为:
