Abstract: A structured material assembly for removing CO2 from a gas, comprises a substrate, a sorbent for adsorbing CO2 from the gas, and a desorption material integrated into the structured material assembly, which is responsive to inputted energy to generate heat to desorb CO2 from the sorbent. The CO2-containing gas may comprise ambient air.

Abstract: Processes are described for removal of CO2 from a CO2-containing gas comprising water vapor, including: (a) contacting the CO2-containing gas comprising water vapor with an alkali metal carbonate adsorbent under conditions causing (i) the water vapor in the CO2-containing gas comprising water vapor to react with the alkali metal carbonate to form a corresponding alkali metal carbonate hydrate, and (ii) the corresponding alkali metal carbonate hydrate to react with CO2 in the CO2-containing gas comprising water vapor to form a corresponding alkali metal sesquicarbonate; and (b) reacting the alkali metal sesquicarbonate under conditions effective to recover CO2 and to regenerate alkali metal carbonate hydrate adsorbent therefrom. Systems for carrying out such process are also described, which are applicable to direct air capture (DAC) of CO2, as well as to treatment of CO2-containing flue gases from power plants and other oxidation and combustion sources.
