Abstract

CO₂/N₂ separation by novel adsorbents presents a promising method for reducing CO₂ emission. Water effects on CO₂ adsorption and CO₂/N₂ selectivity is critical to enable utilization of the adsorbents in practical applications.

Researchers synthesized Ni/DOBDC (Ni-MOF-74 or CPO-27-Ni) through a solvothermal reaction.  The pellet sample was used in a fixed-bed CO₂/N₂ breakthrough study with and without H₂O. Experimental results indicate a promising future for use of the Ni/DOBDC in capturing CO₂ from flue gas.
