Deep removal of trace C₂H₂ and CO₂ from C₂H₄ by using customized potassium-exchange mordenite.

ABSTRACT: Adsorptive separation using porous materials is a promising approach for separating alkynes/olefins due to its energy efficiency, while the deep removal of trace amounts of C₂H₂ and CO₂ from C₂H₄ is still very challenging for a commercial adsorbent. Herein, we report a low-cost inorganic metal cation-mediated mordenite (MOR) zeolite with the specific location and distribution of K⁺ cations acting as a goalkeeper for accurately controlling diffusion channels, as evidence of the experimental and simulation results. Deep purification of C₂H₄ from ternary CO₂/C₂H₂/C₂H₄ mixtures was first realized on K-MOR with exceptional results, achieving a remarkable
