The ionic liquids used are tetrabutylammonium acetate [TBA] [OAC] and tetrabutylammonium bromide [TBA] [Br] The recovery of solvent was performed for three various temperatures 358, 368 and 373 K. The searchings for reveal that solvent blends of MEA with [TBA] [Br] exhibit greater regrowth efficiency and reduced regeneration energy than MEA with [TBA] [OAC] blends with a minimum structure of 2 wt% [TBA] [Br] Energy consumption for healing of 2 wt% [TBA] [Br] blend with 28 wt% MEA was found to be 65. 66 KJ mole − 1 of CO2 which is 41. 97% less than 30 wt% MEA.

IL‐modified adsorbents have the benefits of both ILs and porous supports, such as high CO2 selectivity and high particular surface area, which are novel agents to capture CO2 with broad application leads. In this review, greater than 140 IL‐modified adsorbents for CO2 capture in current years were methodically summed up. The types of ILs consisting of traditional ILs and functionalized ILs on CO2 separation efficiency of different IL hybrid adsorbents, and their adsorption mechanisms were talked about.
