| 摘 要： | 采用液相离子交换法制备了Cu+-13X及负载稀土元素Ce的Ce/Cu+-13X分子筛吸附剂。采用固定床动态吸附实验考察了Ce/Cu+-13X对2,5-二甲基噻吩、苯并噻吩动态吸附性能。研究结果表明,稀土元素Ce的引入可以促进Cu+-13X对2,5-二甲基噻吩和苯并噻吩的吸附性能,同时减弱竞争吸附。在床层高度为16 cm、进样速度为16 mL/h、停留时间为30 min时,效果最佳。

| Abstract: | Adsorbents,Cu+-13X and Ce/Cu+-13X,are prepared by liquid ion-exchange method.Dynamic adsorption experiments with fixed bed are conducted to investigate the dynamic adsorption performance of 2,5-dimethylthiophene and benzothiophene on Ce/Cu+-13X zeolites.The results show that the introduction of rare-earth element Ce can promote the adsorption performance of 2,5-dimethylthiophene and benzothiophene on Ce/Cu+-13X zeolites,and weaken the competitive adsorption.The best results are obtained under the conditions... |
