Different behavior of two iso‐structural zeolitic imidazolate frameworks in ethane–ethylene separation: Study of H 2 ‐CO 2 and CH 4 ‐CO 2 separation capacity

The separation of ethane–ethylene mixtures was evaluated using two zeolitic imidazolate frameworks, which are only different from the assemble metal, as stationary phase from inverse gas chromatography data. The chromatographic profiles exhibited peaks adequately resolved. Separation is attributed to the pore sizes of the adsorbents that discern between ethane and ethylene molecule shapes and closed kinetic diameters. The adsorption heats were...
