ABSTRACT

In the capture of Carbon dioxide (CO2) gas, in relation to Carbon Capture and Sequestration (CCS), one finds many specific studies where different methods have been reported. It is useful to provide a short review of system studies that specifically apply to CO2 adsorption/absorption capture in the current literature. Besides the main CCS technologies, one finds some other related methods, including membrane gas separation, cryogenic CO2 separation, CO2 clathrate formation. The need for controlling anthropogenic CO2 emissions from various combustion processes and lowering the emissions concentration of greenhouse gases in the atmosphere has obvious procedure for environmental issues of mankind. A magnesium-based material is presented that has the highest surface area magnesium microporous coordination polymers yet reported and displays ultrahigh affinity based on heat of adsorption for CO2. Selective capture of CO2, which is essential for natural gas purification and CO2 sequestration, has been reported in zeolites, porous membranes, and amine solutions.
