Trace and low concentration CO₂ removal methods and apparatus utilizing metal organic frameworks

摘要

In general, this disclosure describes techniques for removing trace and low concentration CO₂ from fluids using SIFSIX-n-M MOFs, wherein n is at least two and M is a metal. In some embodiments, the metal is zinc or copper. Embodiments include devices comprising SIFSIX-n-M MOFs for removing CO₂ from fluids. In particular, embodiments relate to devices and methods utilizing SIFSIX-n-M MOFs for removing CO₂ from fluids, wherein CO₂ concentration is trace. Methods utilizing SIFSIX-n-M MOFs for removing CO₂ from fluids can occur in confined spaces. SIFSIX-n-M MOFs can comprise bidentate organic ligands. In a specific embodiment, SIFSIX-n-M MOFs comprise pyrazine or dipryidilacetylene ligands.
