Metal-organic frameworks (MOFs) are a class of materials with incredibly high surface areas, some of which have the ability to preferentially adsorb materials like carbon dioxide. By flowing air or post-combustion gas streams over beds of selected MOFs, carbon dioxide can be selectively removed and later recovered in a controlled manner. Our continuous flow process and patented reactor designs are breaking some of the scale and cost paradigms that have historically held back the use of these incredible materials.
