Abstract

Chemical reactions associated with the absorption of CO ₂ into aqueous solutions of blends of piperazine (PZ) with N-methyldiethanolamine (MDEA), etc. were studied by ¹³C-NMR spectroscopy. The coexistence of PZ and MDEA enhanced the initial apparent rate of HCO ^- ₃ /CO ^2- ₃ formation. This result can be explained by considering that PZ monocarbamate rapidly formed works as an organocatalyst in the formation reaction of HCO ^- ₃ . Concentration changes of chemical species in CO ₂-absorbed aqueous amine solutions upon heating (80 °C, 30 min) were studied by ¹³C-NMR spectroscopy. Carbon dioxide regeneration originates mainly from HCO ^- ₃ /CO ^2- ₃, and not from carbamate and carbonate.
