The capture and geosequestration of CO2 emissions from major point sources such as coal combustion power generators could reduce anthropogenic greenhouse gas emissions and so help to slow global warming. Amine materials such as polyethyleneimine (PEI) loaded onto mesoporous silicas can exhibit large, reversible, water tolerant, and highly selective CO2 capacities and fast sorption kinetics and so can be considered in conjunction with Vacuum Swing Adsorption (VSA), Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA) processes as one approach to the selective capture of CO2 from flue gas.
