Abstract

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/CO 2 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 2 . The separation and purification of acetylene over ethylene was also possible for MIL-100(Fe) activated at 423K. According to the data obtained from operando IR spectroscopy, the unsaturated Fe III sites and surface OH groups are mainly responsible for the successful separation of the acetylene/ethylene mixture, whereas the unsaturated Fe II sites have a detrimental effect on both separation and purification. The potential of MIL-100(Fe) for the separation of a mixture of C 2 H 2 /CO 2 was also examined by using the IAST calculations and transient breakthrough simulations. Comparing the IAST selectivity calculations of C 2 H 2 /CO 2 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.
