在合成离子液体FeCl3-[bmim]Cl的基础上,考察了摩尔比、离子液体加入量、脱硫时间以及脱硫温度对汽油脱硫效果的影响。实验结果表明,FeCl3与[bmim]Cl的摩尔比为2∶1,加入量10%,反应时间35min,温度25℃时脱硫效果最好,脱硫率达到81.5%,汽油收率达到了92.5%。
Based on the synthesis of FeCl3- [bmim] Cl, the effects of molar ratio, ionic liquid addition, desulfurization time and desulfurization temperature on the desulfurization efficiency of gasoline were investigated. The experimental results show that the molar ratio of FeCl3 to [bmim] Cl is 2:1, the addition amount is 10%, the reaction time is 35min, the desulfurization efficiency is the best when the temperature is 25 ℃, the desulfurization rate reaches 81.5% and the gasoline yield reaches 92.5%.
