Abstract: Five microporous MOFs were synthesized and their static adsorption properties for light hydrocarbons were experimentally investigated at 298 K and 150 kPa. Among the five MOFs, HKUST-1 and Ni(bdc)(ted)0.5 exhibited much higher uptakes of ethane and propane than PCN-250, UiO-66, and ZIF-8. Breakthrough experiments were carried out at 298 K and atmospheric pressure on HKUST-1 and two commercially used adsorbents. HKUST-1 exhibited a much lower dynamic than static adsorption capacity. Moreover, HKUST-1 and the two traditional adsorbents could effectively separate binary (ethane/propane) and ternary (ethane/propane/toluene) mixtures.
