Air collector with functionalized ion exchange membrane for capturing ambient CO
An apparatus for capture of CO 2 from the atmosphere comprising an anion exchange material formed in a matrix exposed to a flow of the air.
1. A method for removing CO 2 from air, comprising the steps of: (a) passing the air in contact with an apparatus comprising a solid capture material comprising an amine, whereupon CO 2 is captured directly by the solid capture material; (b) treating the solid capture material to remove and concentrate the captured CO 2 ; and (c) using the captured CO 2 from step (b) in the production of a useful product.
2. The method of claim 1 , wherein the useful product is a fuel or a plastic.
3. The method of claim 1 , wherein the solid capture material is an anion exchange material.
4. The method of claim 3 , wherein the anion exchange material is coated on an inert substrate material.
5. The method of claim 1 , wherein said treating comprises treatment with a liquid.
6. The method of claim 5 , wherein said liquid comprises a sorbent chemical.
7. The method of claim 1 , wherein said solid capture material is formed as a matrix, a honeycomb, or a mesh.
