The various embodiments of the present invention relate to compositions, apparatus, and methods comprising sorbent fibers. More particularly, various embodiments of the present invention are directed towards sorbent fiber compositions for temperature swing adsorption processes. Various embodiments of the present invention comprise sorbent fiber compositions, apparatus comprising a plurality of sorbent fibers, and methods of using the same for the capture of at least one component from a medium, for example CO2 from flue gas.

1. A method of adsorbing a component of a medium, the method comprising: contacting a medium with a hollow fiber comprising a plurality of tortuous pathways, a sorbent material in fluid communication with the plurality of tortuous pathways, a lumen disposed within the hollow fiber, and a barrier lay
1. A method of adsorbing a component of a medium, the method comprising: contacting a medium with a hollow fiber comprising a plurality of tortuous pathways, a sorbent material in fluid communication with the plurality of tortuous pathways, a lumen disposed within the hollow fiber, and a barrier layer lining the lumen to prevent fluid communication between the lumen and the plurality of tortuous pathways; andselectively adsorbing a component of the medium with the sorbent material. 2. The method of adsorbing a component of a medium of claim 1, further comprising desorbing the component of the medium. 3. The method of adsorbing a component of a medium of claim 2, further comprising repeating the contacting and adsorbing. 4. The method of adsorbing a component of a medium of claim 3, wherein a cycle time between successive adsorptions is less than about 2 minutes. 5. The method of adsorbing a component of a medium of claim 1, wherein the medium comprises flue gas, natural gas, fuel gas, bio gas, town gas, waste gas, water, coal gas, air, or a carbon dioxide containing medium. 6. The method of adsorbing a component of a medium of claim 1, further comprising preventing fluid communication between the medium and a heat exchange fluid. 7. The method of adsorbing a component of a medium of claim 1, wherein the component is selected from CO2, SOx, NOx, and water. 8. The method of adsorbing a component of a medium of claim 1, wherein the component is CO2. 9. The method of adsorbing a component of a medium of claim 8, wherein the medium is comprised of CO2 and nitrogen, and the sorbent material has a selectivity for adsorbing CO2 over nitrogen of greater than 5. 10. The method of adsorbing a component of a medium of claim 8, wherein the medium is comprised of CO2 and nitrogen, and the sorbent material has a selectivity for carbon dioxide over nitrogen of about 10 to about 60 and a heat of sorption of about −25 kiloJoules per mole of carbon dioxide to about −90 kiloJoules per mole of carbon dioxide. 11. The method of adsorbing a component of a medium of claim 9, wherein the medium comprises at least one of a flue gas, natural gas, fuel gas, bio gas, town gas, waste gas, water, coal gas, air, or other carbon dioxide-containing medium. 12. The method of claim 9, wherein the medium is comprised of a flue gas stream.
