CO2‐Alkanolamine Reaction Kinetics: A Review of Recent Studies
TLDR
In this paper, the authors provide an overview on the kinetics of the reaction of CO2 with aqueous solutions of alkanolamines, and various reaction mechanisms that are used to interpret experimental kinetic data.Abstract:
Alkanolamines are the most popular absorbents used to remove CO2 from process gas streams. Therefore, the CO2 reaction with alkanolamines is of considerable importance. The aim of this article is to provide an overview on the kinetics of the reaction of CO2 with aqueous solutions of alkanolamines. The various reaction mechanisms that are used to interpret experimental kinetic data – zwitterion, termolecular and base-catalyzed hydration – are discussed in detail. Recently published data on reaction kinetics of individual amine systems and their mixtures are considered. In addition, the kinetic behavior of several novel aminebased solvents that have been proposed in the literature is analyzed. Generally, the reaction of CO2 with primary, secondary and sterically hindered amines is governed by the zwitterion mechanism, whereas the reaction with tertiary amines is described by the base-catalyzed hydration of CO2.read more

Douglas W. Stephan,Gerhard Erker +1 more
TL;DR: Sterically encumbered Lewis acid and Lewis base combinations do not undergo the ubiquitous neutralization reaction to form "classical" Lewis acid/Lewis base adducts, but both the unquenched Lewis acidity and basicity of such sterically "frustrated Lewis pairs (FLPs)" is available to carry out unusual reactions.

Post-combustion CO2 capture with chemical absorption: A state-of-the-art review
TL;DR: In this article, the authors provide a state-of-the-art assessment of the research work carried out so far in post-combustion capture with chemical absorption. And they try to predict challenges and potential new developments from different aspects such as new solvents, pilot plants, process heat integration (to improve efficiency), modelling and simulation, process intensification and government policy impact.

The reaction of CO2 with ethanolamines
TL;DR: In this article, the rates of homogeneous reaction of mono-, di- and tri-ethanolamine by various workers are compared and it seems probable that a zwitterion is the intermediate in the formation of carbamate and that the reaction of DEA (but not of MEA) is catalysed by bases
