【 摘 要 】

The stability to thermal degradation of aqueous solutions of methyldiethanolamine (MDEA) and their mixtures with glycine (Gly), in the absence and the presence of CO2, was investigated by Gas chromatography-flame ionization detector (GC-FID). The results showed that the presence of CO2 influenced significantly the degree of thermal degradation of these solutions. The investigated MDEA solutions were found less susceptible to thermal degradation in the absence of CO2. However, in the presence of CO2, the thermal degradation was more significant. The addition of glycine (Gly) to MDEA solution reduces the MDEA thermal degradation. It was concluded that MDEA + Gly amine/amino acid aqueous blend could be a potentially interesting absorbent for industrial CO2 capture applications.
