Abstract
Official abstract text for this publication.
A system and method for acid-gas capture wherein organic acid-gas capture materials form hetero-atom analogs of alkyl-carbonate when contacted with an acid gas. These organic-acid gas capture materials include combinations of a weak acid and a base, or zwitterionic liquids. This invention allows for reversible acid-gas binding to these organic binding materials thus allowing for the capture and release of one or more acid gases. These acid-gas binding organic compounds can be regenerated to release the captured acid gasses and enable these organic acid-gas binding materials to be reused. This enables transport of the liquid capture compounds and the release of the acid gases from the organic liquid with significant energy savings compared to current aqueous systems.
First claim
Opening claim text (preview).
What is claimed is: 1. A reversible zwitterionic liquid having the structure wherein R1 is selected from the group consisting of alkyl, aryl, silyl, ether, and ester, R2 is selected from the group consisting of alkyl, aryl, silyl, ether, and ester, X1 is selected from the group S, and O; X2 is S; n is between 1 and 20 carbon links or an organic linker, and Y is any structure th…
