Sammendrag
CO2 capture with alkanolamines has been in use since 1930, where 2-ethanolamine (MEA) is the most studied absorbent for post-combustion. In order to prevent degradation, it is important to understand the degradation mechanisms, which in turn requires knowledge of both stoichiometry and kinetics of the reactions and chemical pathways associated with degradation. In the present work thermal degradation with CO2 in closed cylinders at 135 °C is performed on already oxidatively degraded solutions from both an open batch and a closed batch setup. Thermal degradation with CO2 on oxidatively degraded solutions seems to give typical thermal degradation compounds.
