Abstract:
1. A method to separate carbon dioxide from an exhaust stream from a combustion source, the method comprising a repeatable cycle comprising the steps of a. providing a bed comprising a CO b. contacting the bed with a combustion exhaust gas to remove CO c. thereafter, contacting the bed containing solid-state adsorbent having CO2 adsorbed thereon with a sweep gas comprising steam to remove combustion exhaust gas remaining in the bed; d. thereafter, contacting the bed with steam to thereby remove CO e. conveying the gas comprising steam and CO f. utilizing the water and heat recovered by the vapor recompression system to generate the sweep gas comprising steam, wherein, upon performance of the cycle, more than about 90% of the carbon contained in the combustion exhaust gas is recovered.
