A mathematical model was established to investigate the binary adsorption process of CO₂ and H₂O in vertical radial-flow adsorbers. The results showed that the variation law of the adsorption performance of the four types of adsorbers is similar to that of the flow uniformity. The flow uniformity can be used to indirectly reflect the adsorbent utilization and the adsorption performance of the adsorbers. The breakthrough regions and main adsorption regions of the different flow forms of the adsorbers are different. The centrifugal π-type adsorber has the best performance among the four types of adsorber. Compared with the centripetal Z-type adsorber, the pressure drop of the centrifugal π-type adsorber is reduced by 12.0 %, and the adsorption time of the centrifugal π-type adsorber is increased by 134 %.

基于CO2和H2O二元吸附的四种垂直径向流动吸附器的比较

建立数学模型研究CO ₂和H _{2的二元吸附过程}O 在垂直径向流动吸附器中。结果表明，四种吸附剂吸附性能的变化规律与流动均匀性的变化规律相似。流动均匀度可以间接反映吸附剂的利用率和吸附剂的吸附性能。不同流动形式的吸附器的突破区和主要吸附区是不同的。离心式π型吸附器在四种吸附器中性能最好。与向心Z型吸附器相比，离心π型吸附器的压降降低了12.0%，离心π型吸附器的吸附时间增加了134%。
