摘要：
Chemical reactions associated with the absorption of CO2 into aqueous solutions of blends of piperazine (PZ) with N-methyldiethanolamine (MDEA), etc. were studied by C-13-NMR spectroscopy. The coexistence of PZ and MDEA enhanced the initial apparent rate of HCO3-/CO32- formation. This result can be explained by considering that PZ monocarbamate rapidly formed works as an organocatalyst in the formation reaction of HCO3-. Concentration changes of chemical species in CO2-absorbed aqueous amine solutions upon heating (80 degrees C, 30 min) were studied by C-13-NMR spectroscopy. Carbon dioxide regeneration originates mainly from HCO3-/CO32-, and not from carbamate and carbonate.(C) 2013 The Authors. Published by Elsevier Ltd. Open access under CC BY-NC-ND license.
