Kinetic Study of Post Combustion CO2 Absorption by Methyldiethanolamine 30 wt.% and Hexylamine 10 wt.% as New Aqueous Solution

The main drawback of conventional alkanolamines for post combustion CO2 capture is that they cannot combine a low energy consumption for regeneration and a high reactivity. Blends of tertiary and primary amines provide these two advantages at the same time. This study considers a new composition of...
