N2 - In this work, room temperature ionic liquids (RTILs) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF4) and 1-butyl-3-ethylimidazolium tetrafluoroborate ([BEIM]BF4) are synthesized. The cation structure of ionic liquids is confirmed by NMR spectroscopy. The thermal decomposition temperature of synthesized ionic liquids is measured and both ionic liquids show good thermal stability. The viscosity of ionic liquids is determined over the temperature range of 298 K to 353 K. A mixed system made by blending amine and ionic liquid is proposed for CO2 capture. Investigation of the performance of this binary system on a porous support medium for CO2 absorption shows that amine is able to greatly intensify the ionic liquids' ability to absorb CO2. Furthermore, when blending tertiary amine and ionic liquids to absorb CO2, it was found that only physical absorption takes place and that the viscosity of the absorbent increases slightly after CO2 absorption. Based on the results of this work, the binary system of tertiary amine and RTILs is proven to be an alternative absorbent for CO2 capture.
