Abstract
A method for regenerating an amine-containing sorbent material useful in COcapture, the method comprising exposing an amine-containing sorbent-COcomplex to microwave radiation to result in release of COand regenerated amine-containing sorbent that is uncomplexed with CO, wherein the amine-containing sorbent-COcomplex contains either: (i) a carbamate bond; or (ii) an ion pair bond of the formula wherein R, R, and Rare selected from H and hydrocarbon groups containing at least one carbon atom, wherein at least one of R, R, and Ris H; Xis a carbonate or bicarbonate anion, with m being 1 for bicarbonate and 2 for carbonate; and n is an integer of 1 or 2, provided that n×m=2. The method may also include re-using the regenerated amine-containing sorbent to capture carbon dioxide.
