Abstract: The experimental study of CO2 absorption in ionic liquids: [Emim][Ac] and [Bmim][Ac] in packed bed column is presented. The influence of initial CO2 concentration, absorption temperature and water content in ionic liquid on removal efficiency was investigated. The results show that in the same experimental conditions ILs have comparable CO2 absorption capacities with amine solution. However ILs need much longer times to absorb the same amount of carbon dioxide from gas mixture.
