Title:
AMINE PROMOTION FOR CO2 CAPTURE
Document Type and Number:
WIPO Patent Application WO/2014/099241
Kind Code:
A3
Abstract:
Promoter amines are used to enhance CO2 uptake 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 CO2 capture and release system that involves a phase transition from a solution of amine-CO2 products to a slurry of amine-CO2 precipitate solids.
