Abstract

Abstract: The separation of carbon dioxide from flue gas is essential for the reduction of greenhouse gas emissions. In adsorptive methods, the challenge lies in the choice of suitable porous materials. Among all zeolite topologies, a number of adsorbents with pore dimensions in the range of the guest molecules were identified to allow an excellent separation by diffusion, and MRE and AFO zeolite topologies appear to be the best candidates based on equilibrium adsorption. Also, it was found that the behavior of this gas mixture in DFT and APD zeolites differed from the normal behavior. Abstract : Highly selective zeolites were used to remove CO2 from flue gas. A number of zeolite candidates for diffusion‐based separations were found, taking advantage of the diameter of their pore apertures.
