Methane, the principle component of natural gas, is available in large quantities and is preferable to other hydrocarbon fuels because of its cleaner combustion. Moreover methane has the highest H/C ratio, and consequently a higher research octane number than other fuels. In this work, Methane (CH4), and Carbon dioxide (CO2) adsorption on iron terephthalate (MOF-235) were studied. At first, we synthesized MOF-235 using 1, 4- Benzenedicarboxylic acid (terephthalic acid) and ferric chloride hexahydrate (FeCl3•6H2O) under autogeneous pressure. Resulting sample was characterized by X-Ray diffraction (XRD), Brunauer- Emmet- Teller (BET) and Fourier transform infrared (FT-IR) methods. CH4 and CO2 adsorption capacities were measured separately and by volumetric method. MOF-235 showed CH4 and CO2 adsorption capacities of 2.5 and 0.17 (m.mol of gas adsorbed. g- adsorbent-1), respectively. The high selectivity for CH4 over CO2 (14.7), suggests that MOF-235 is a potential adsorbent material for the separation of CH4 from gas mixtures.
