| Popis: | This study describes the chemical capture of CO2 by AMP and some AMP–alkanolamine blends, namely IPMEA, TBMEA and MDEA, in non-aqueous solvents. The solvents used are a mixture of ethylene glycol and 1-propanol or single diethylene glycol monomethyl ether. A gas mixture containing 15% of CO2 in air was used for the experiments. We designed two different experimental procedures: 1) batch experiments of CO2 absorption and desorption aimed at investigating the absorption and desorption properties of the different absorbents; 2) continuous cycles of CO2 absorption (20 °C) and desorption (90-95 °C) in packed columns in order to investigate the CO2 absorption efficiency. The CO2 removal efficiency at equilibrium was in the range 87-95% depending on the operational conditions. The identification and the quantification of the species in solution were obtained from 13C NMR spectroscopic analysis. |
