Disclosed is a method for removing carbon dioxide from a gas stream, comprising placing the gas stream in contact with a resin, wetting the resin with water, collecting water vapor and carbon dioxide from the resin, and separating the carbon dioxide from the water vapor. The resin may be placed in a chamber or a plurality of chambers connected in series wherein the first chamber contains resin that was first contacted by the gas, and each successive chamber contains resin which has been wetted and carbon dioxide collected from for a greater period of time than the previous chamber, and so on, until the last chamber. Secondary sorbents may be employed to further separate the carbon dioxide from the water vapor.

The method of claim 1, wherein the resin is wetted by immersion in a liquid. 3. The method of claim 2, wherein the liquid is water and also contains carbonic anhydrase. 4. The method of claim 1, wherein the liquid comprises a secondary sorbent. 5. The method of claim 4, wherein the secondary sorbent is a weak liquid amine. 6. The method of claim 4, wherein the carbon dioxide is released from the secondary sorbent upon an increase in temperature. 7. The method as recited in claim 1, wherein upon evacuating said gas stream, said chamber is at a near vacuum pressure. 8. The method as recited in claim 1, wherein a plurality of chambers comprising the resin are connected in series, and wherein the liquid enters the first chamber and exits through a last chamber, the carbon dioxide and liquid being collected from said last chamber. 9. A method for removing carbon dioxide from a gas, comprising bringing said gas in contact with a resin in a chamber, evacuating gas from the chamber, wetting said resin with liquid water, collecting liquid water and carbon dioxide from said resin, and separating said carbon dioxide from said liquid water. 10.
