Adsorptive performance of benzothiophene using metal organic framework material MOF-5

Removal of benzothiophenic compounds from fuels plays a key role in deep desulfurization. The adsorptive performance of benzothiophene with typical Metal-Organic Frameworks material MOF-5 was investigated using batch experiments. Results showed that the adsorption kinetics data of benzaothiophene onto MOF-5 from model fuel could be well described by a pseudo-second-order model. The adsorption equilibrium data of benzaothiophene onto MOF-5 fitted well to the Langmuir, Freundlich and Dubinin-Radushkevich (D-R) isotherm models (Freundlich>D-R>Langmuir). Thermodynamic parameters showed that the adsorption of benzaothiophene onto MOF-5 was spontaneous and endothermic in nature.
