Solid amine absorbents and the adsorptive property of CO2 are reviewed. The type of amine and support materials including carbon-based sorbents, zeolite-based sorbents, silica-based sorbents and polymer-based sorbents for CO2 adsorption are compared. The research progress of each technology and their advantages and disadvantages are reviewed. Meanwhile the influencing factors of adsorptive property of silica-based sorbents are discussed, in- cluding the presence of water, adsorption temperature and CO2 partial pressure etc. It indicates that the promising and significant research areas in the future are the selection of amines and physicochemical property of molecular sieve.
