Abstract

Kinetics of CO2 reactions with blended solutions of N-methyldiethanolamine (MDEA) and salts of Glycine and Taurine are presented in this work. The obtained results show that the new blended solutions could be promising absorbents for CO2 capture from natural and industrial flue gases. The reaction kinetics were investigated using stopped flow technique at temperatures ranging from 293 to 313 K. The kinetics data obtained in the fast reaction regime and amine concentration in the range of 0.2 to 0.8M were analyzed using zwitterion mechanism, and the kinetic parameters associated to the reactions were determined. Individual rate constants were obtained by nonlinear regression at each temperature and the activation energy of each reaction was estimated from Arrhenius plot.
