Abstract [en]

Deep eutectic solvents (DESs) as ionic liquids (ILs) analogues show great potential in CO2 capture. They exhibit favorable solvent properties and are considered as economical alternatives to conventional ILs. In this study, we prepare 35 DESs and screen in terms of their CO2 solubility and viscosity that are two crucial factors to be considered upon the design of efficient CO2 sorbents. The influence of salt and hydrogen bond donor nature and structure, their molar ratio on the CO2 solubility and viscosity of DESs are investigated. The viscosity and CO2 solubility of the DESs are compared with other DESs or conventional ILs. 15 DESs which exhibit comparable CO2 absorption capacity with those of choline chloride-urea or glycerol DESs or fluorinated ILs, are chosen as promising one. The viscosity of selected DESs are below 200 mPa[middle dot]s and are lower than choline chloride-based DESs. Since the viscosity of DESs is relatively high an par to those of conventional ILs, the effect of water as a co-solvent are investigated in order to decrease the viscosity. The addition of water to high viscosity glycerol-based DESs improves the kinetics of absorption by decreasing the viscosity thus increases the CO2 absorption capacity. Dry or aqueous DESs that demonstrate high sorption capacity and low viscosity are chosen for further analysis and characterization in future and further functionalization will be carried out to improve their sorption capacity.
