摘要

摘要: 苯并噻吩类硫化物的脱除是燃油实现深度脱硫的关键。实验研究了典型的金属有机骨架材料MOF-5吸附苯并噻吩性能。结果表明,MOF-5对模型油中苯并噻吩的吸附动力学过程满足拟二级动力学模型。Langmuir、Freundlich和Dubinin-Radushkevich (D-R) 三种等温吸附模型均可较好地描述MOF-5对苯并噻吩的等温吸附行为 (Freundlich>D-R>Langmuir)。热力学参数表明,MOF-5对苯并噻吩的吸附是自发的吸热吸附过程。

Abstract: 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.
