摘要
噻吩类硫化物的脱除是燃油能否实现生产超低硫清洁燃油的关键.本文研究了双金属有机多孔材料Ni-Cu/BTC吸附燃油中噻吩的性能.结果表明,Ni-Cu/BTC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)3种等温吸附模型均可较好地描述Ni-Cu/BTC对苯并噻吩的等温吸附行为(Freundlich>D-R>Langmuir).热力学参数表明Ni-Cu/BTC对噻吩的吸附是自发的吸热过程.
Removal ofthiophenic compounds from fuels plays a key role in production of ultra low sulfur clean fuel. The adsorptive performance of thiophene with bimetallic organic porous material Ni-Cu/BTC was investigated using batch experiments. Results showed that the adsorption kinetics data of thiophene onto Ni-Cu/BTC from model fuel could be well described by a pseudo-second-order model. The adsorption equilibrium data of thiophene onto Ni-Cu/BTC fitted well to the Langmuir, Freundlich and Dubinin-Radushkevich （D2R） isotherm models （Freundlich〉D-R〉Langmuir）. Thermodynamic parameters showed that the adsorption of thiophene onto Ni-Cu/BTC was spontaneous and endothermic in nature.
