Abstract:
The invention relates to regenerative, supported amine sorbents that includes an amine or an amine/polyol composition deposited on a nano-structured support such as nanosilica. The sorbent provides structural integrity, as well as high selectivity and increased capacity for efficiently capturing carbon dioxide from gas mixtures, including the air. The sorbent is regenerative, and can be used through multiple operations of absorption-desorption cycles.
