New experimental data for adsorption of ethylene and ethane on zeolite 13X and zeolite 5A are reported at a temperature range of 288–308 K and pressure up to 20 bar. The cation exchange for zeolites 13X and 5A was performed using copper, and the observed adsorption capacities of the copper-exchanged zeolites were measured. The equilibrium adsorption capacities of these adsorbents toward ethylene and ethane were compared. The copper-exchanged zeolites showed improved adsorption capacities toward both gases, where CuA was found to have the highest adsorption capacity. However, the copper-exchanged zeolites 13X and 5A underperformed in comparison to the expected high selectivity for ethylene/ethane separation. The data utilized for expressing the adsorption isotherm were successfully correlated with the Toth model, and the parameters for this model were calculated as reported in this paper.

铜交换沸石13X和5A上乙烯和乙烷气体吸附的实验测量

据报道，在288–308 K的温度范围和最高20 bar的压力下，乙烯和乙烷在13X和5A沸石上吸附的新实验数据。使用铜进行沸石13X和5A的阳离子交换，并且测量观察到的铜交换沸石的吸附容量。比较了这些吸附剂对乙烯和乙烷的平衡吸附能力。铜交换沸石对两种气体均显示出更高的吸附能力，其中CuA具有最高的吸附能力。然而，与预期的乙烯/乙烷分离的高选择性相比，铜交换沸石13X和5A的性能差。用于表达吸附等温线的数据已成功与Toth模型相关联，
