为了提高碳捕集技术吸收效率、降低再生能耗、避免二次污染,提出一种利用 N-甲基环己胺 MCA水溶液及甲基咪唑离子液体混合吸收二氧化碳(CO2)的方法以实现燃煤电厂烟气碳减排,并分别开展了基于 MCA水溶液·1-丁基-3-甲基咪唑四硼氟酸盐[Bmim][BF4]体系和MCA水溶液·1-丁基-3-甲基咪唑醋酸盐[Bmim][OAc]体系的CO2吸收及再生性能实验。实验结果表明,10%MCA+10%H2 O+[Bmim][OAc]体系的吸收容量为0.369,吸收速率为5.83 g/(kg·min),优于工业常压吸收剂30%MEA水溶液；再生性能相较于10%MCA溶液明显改善。

In order to improve absorption rate of CO2 capture technology,reduce regeneration energy consumption and a-void secondary pollution,a kind of method for absorbing CO2 by using blends of N-methylcyclohexylamine(MCA)and imid-azolium based ionic liquids so as to realize flue gas CO2 emission in coal-fired power plant. Tests on CO2 absorption and re-generation performance based on 1-buty1-3-methylimidazolium tetrafluoroborate-based system([Bmim][BF4])and 1-buty1-3-methylimizazaolium acetate([Bmim][OAc])system were developed. Results indicated that CO2 absorption capacity of 10%MCA+10%H2 O+[Bmim][OAc]system was 0.369 and absorption rate was 5.83 g/(kg ·min)which was superior to that of 30% MEA system. In addition,regeneration performance of this system was obviously improved compared with 1 0% MCA system.
