A mathematical model of binary adsorption of CO₂ and H₂O is established to investigate the adsorption process of a vertical radial flow adsorber (VRFA). The competitive adsorption laws of CO₂ and H₂O in the VRFA are analyzed, the relationships between various indexes of adsorption performance are quantitatively compared, and the fitting correlation reflecting the adsorption performance is obtained. The results indicate that the main affecting parameters of flow uniformity and adsorption time are different, so it is inappropriate to only use the flow uniformity as the unique index of adsorption performance. The fitting correlation of adsorption time is obtained by central composite Design (CCD) and Kriging methods with a fitting degree of 99.1 %, which can be used to guide the design of the VRFA.

基于CO2和H2O二元吸附的垂直径向流动吸附器性能评价

_{建立了CO 2}和H ₂ O二元吸附的数学模型，研究了垂直径向流动吸附器（VRFA）的吸附过程。CO ₂和H _{2的竞争吸附规律}对VRFA中的O进行分析，定量比较吸附性能各项指标之间的关系，得到反映吸附性能的拟合关系。结果表明，影响流动均匀度和吸附时间的主要参数不同，仅用流动均匀度作为吸附性能的唯一指标是不合适的。通过中心复合设计(CCD)和Kriging方法得到吸附时间的拟合关系，拟合度为99.1 %，可用于指导VRFA的设计。
