合成了低黏度离子液体[Amim]Cl/ZnCl_2,并将其作为萃取剂对页岩油柴油中的碱性氮化物进行萃取脱除实验。考察不同温度、剂油质量比、时间下离子液体的脱氮效果。结果表明,反应温度为30℃,剂油质量比为1∶7,反应时间为20 min和沉降时间为2 h下,[Amim]Cl/ZnCl_2的脱氮率可达86%,且经过4次重复试验后仍能达到53%。
The low viscosity ionic liquid [Amim] Cl / ZnCl_2 was synthesized and used as extractant to extract and remove alkaline nitrides in shale oil and diesel oil. Investigate the different temperature, oil quality ratio, the time under the effect of nitrogen removal of ionic liquids. The results showed that the denitrification rate of [Amim] Cl / ZnCl 2 reached 86% at reaction temperature of 30 ℃, oil mass ratio of 1: 7, reaction time of 20 min and settling time of 2 h, After repeated testing can still reach 53%.
