摘要

Abstract

Amino acid ionic liquid adsorbs CO2 rapidly and N-methyldiethanolamine (MDEA)has high CO2 absorption load.Therefore

tetramethylammonium glycinate (［N1111］［Gly］)was synthesized and mixed with N-methyldiethanolamine (MDEA)aqueous solutions to form complex absorbents.The CO2 absorption capabilities of the complex absorbents were measured with the constant volume method.The results indicated that the absorption capacity per volume increased with CO2 pressure and concentration of ［N1111］［Gly］

while the mole absorptivity at absorption equilibrium was independent of ［N1111］［Gly］ concentration under different CO2 pressures.The absorption of CO2 was also performed in a countercurrent falling film column

showing that the concentration of ［N1111］［Gly］
