A sorbent for CO2 reduction from indoor air from an enclosed space. In some embodiments, the sorbent comprises a solid support and an amine-based compound being supported by the support. The sorbent captures at least a portion of the CO2 within the indoor air. The sorbent may be regenerated by streaming outdoor air through the sorbent to release at least a portion of the captured CO2. The sorbent is structured to allow indoor air to flow therein with relatively low flow resistance and relatively rapid reaction kinetics. Regeneration may be performed at relatively low outdoor air temperatures, thereby minimizing the thermal energy required for regenerating the sorbent.

A sorbent for reduction of CO2 from air of an enclosed space, comprising: a support comprising a plurality of solid particles having an average diameter dimension in the range of 0.1-10 millimeters; andan amine-based compound comprising a polyamine having between 25%-75% of secondary amines and water, and wherein the amine-based compound is configured to capture at least some of the CO2 within the indoor air of the enclosed space and release at least a portion of the captured CO2 by streaming air or other gas through the sorbent. 11. A sorbent according to claim 10, wherein the support is selected from the group consisting of gels, molecular sieves, nanotube-containing materials, porous materials, sponge and sponge-like materials, electro-magnetically charged objects, porous organic polymers, ion exchange resins, polymeric absorbent resins, acrylic ester polymers, polystyrene divinyl benzene, polymethyl methacrylate (PMMA), polystyrene, styrene divinylbenzene (SDB), fly ash, activated carbon, carbon nanotubes, alumina nanoparticles, synthetic zeolite, porous alumina, porous minerals, porous silica, silica nanoparticle, fumed silica, activated charcoal, aluminum phyllosilicates, bentonite, montmorillonite, ball clay, fuller's earth, kaolinite, attapulgite, hectorite, palygorskite, saponite, sepiolitemetal, organic frameworks, and any combination thereof. 12. A sorbent according to claim 10, wherein the support is selected from the group consisting of granules, beads, pellets, extrudates, and any combination thereof. 13. A sorbent according to claim 10, wherein at least 50% of amine functional groups of the amine-based compound are secondary amines. 14. A sorbent according to claim 10, wherein the amine-based compound comprises monoethanolamine (MEA), ethanolamine, methylamine, branched polyethyleneimine (PEI), linear polyethyleneimine (PEI), diethanolamine (DEA), dimethylamine, diethylamine, diisopropanolamine (DIPA) tetraethylenepentamine (TEPA), methyldiethanolamine (MDEA), methylethanolamine, or any combination thereof. 15. A method for reducing CO2 contained in air from an enclosed environment, the method comprising: providing a sorbent comprising a support including a plurality of solid particles having an average diameter dimension in the range of 0.1-10 millimeters; and an amine-based compound comprising a polyamine having between 25%-75% of secondary amines and water,streaming a first gas comprising CO2 from inside an enclosed environment through the sorbent such that the sorbent captures at least some of the CO2 from the first gas; andstreaming a second gas through the sorbent such that the sorbent releases at least some of the captured CO2 to the second gas. 16. The method of claim 15, wherein the second gas comprises less CO2 than the first gas. 17. The method of claim 15, wherein the second gas has a temperature higher than the first gas. 18. The method of claim 15, wherein the second gas is heated prior to streaming the second gas through the sorbent. 19.
