摘　　要：研究了载铜13X的制备以及吸附噻吩的动力学性能.实验考察了负载溶液、还原时间、还原温度以及预处理等方面对吸附剂制备的影响,得到了制备载铜13X吸附剂所需要的最优化条件.采用Crank单孔模型对测定的吸附动力学数据进行拟合,确定了不同温度下的噻吩在载铜13X上的扩散系数.实验结果表明,Crank单孔模型可很好地描述噻吩在载铜13X分子筛上的吸附过程.Preparation of 13X loading with cuprous ion and its adsorption kinetics for thiophene were studied. The effect of solution, reduction temperature, reduction time and pre-reduction process on the preparation of 13X loading with cuprous ion were examined and the preparing conditions were optimized. From the adsorption kinetic data of thiophene on 13X loading with cuprous ion, the Crank monopore model was used to fit the diffusion coefficients at different temperatures. The results proved that Crank monopore model could be used to describe the adsorption process of thiophene on 13X loading with cuprous ion.
