Abstract

In this research, potassium carbonate (K2CO3) solution promoted by glutamic acid salt were used for capturing carbon dioxide (CO2) from flue gas in a packed absorber column at room temperature and at atmospheric pressure. Effect of glutamic acid salt concentrations on the CO2 absorption rates into carbonate solutions and glutamic acid salt were investigated. The results showed that the reaction of CO2 with K2CO3 solution promoted by glutamic acid salt was second-order and the rate constant (k2) was calculated from the experiments. The reaction of CO2 with glutamic acid salt was described using zwitterionic mechanism. The overall reaction kinetic constant (kov) strongly increased with the increase of glutamic acid salt concentration based on the pseudo first-order regime.
