Abstract
Promoter amines are used to enhance COuptake by sterically hindered or tertiary amines. The promoter amines can be cyclic amines, including aromatic cyclic amines or bridged cyclic amines. The combination of a promoter amine plus a sterically hindered or tertiary amines allows for improved uptake kinetics while reducing or minimizing the amount of formation of carbamate salts. The promoted sterically hindered or tertiary amines can be used as part of a COcapture and release system that involves a phase transition from a solution of amine-COproducts to a slurry of amine-COprecipitate solids.
