A reducible Metal–organic Framework (MOF), iron (III) trimesate, denoted as MIL-100 (Fe), was investigated for the separation and purification of methane/ethane/ethylene/acetylene and an acetylene/CO2 mixtures by using sorption isotherms, breakthrough experiments, Ideal Adsorbed Solution Theory (IAST) calculations and IR spectroscopic analysis. The MIL-100 (Fe) showed high adsorption selectivity not only for acetylene and ethylene over methane and ethane, but also for acetylene over CO CO2. The separation and purification of acetylene over ethylene was also possible for MIL-100 (Fe) activated at 423 K. According to the data obtained from operando IR spectroscopy, the unsaturated FeIII sites and surface OH groups are mainly responsible for the successful separation of the acetylene/ethylene mixture, whereas the unsaturated FeII sites have a detrimental effect on both separation and purification. The potential of MIL-100 (Fe) for the separation of a mixture of C CO2H CO2/CO CO2 was also examined by using the IAST calculations and transient breakthrough simulations. Comparing the IAST selectivity calculations of C CO2H CO2/CO CO2 for four MOFs selected from the literature, the selectivity with MIL-100 (Fe) was higher than those of CuBTC, ZJU-60a and PCP-33, but lower than that of HOF-3.
