摘要：

The present research work is centered in the use of nuclear magnetic resonance technique to analyze the carbon dioxide absorption pathways in the chemical absorption process with amine in aqueous solutions. The amines used in present study have shown a high reaction rate for this kind of capture, and this characteristic indicates that these solutes can be a suitable option for the optimization of carbon dioxide capture. This work allows compare the carbon dioxide loading along time with the reaction products present in the liquid phase. Also the experimental results show the presence of each product and it allows confirm the stoichiometry of each system. This last parameter has an important influence upon the carbon dioxide absorption rate and loading. (C) 2012 Published by Elsevier Ltd.
