The main aim of this manuscript was to investigate the effect of amine (MEA, DEA and TEA) functionalization of high surface area supports (Amberlite IR120H, Ambersep 252H, Amberlite 200CNa and Amberlite XAD7HP) on adsorption of CO₂ from gases streams. A saturated factorial design of experiments was initially applied to determine the influence of four amine impregnation variables on amine loading. Except for the amine concentration whose effect was significantly positive on the amount of ethanolamine impregnated in Amberlite XAD7HP (p ≤ 0.05), the other factors had negligible importance. Kinetic experiments of CO₂ adsorption were performed in a fixed bed at different inlet concentrations of CO₂ and temperatures. The amounts of adsorbed CO₂ on the DEA enriched Ambersep 252H, Amberlite 200CNa and Amberlite XAD7HP at bed saturation were ~ 40–400 times as high as those obtained with the same adsorbents without impregnation. DEA enriched Amberlite IR120H and TEA functionalized resins presented small capacities to adsorb CO₂ at the investigated conditions, while MEA enriched resins were effective as CO₂ adsorbents in the case of impregnation in Amberlite 200CNa. A classical fundamental model described correctly the breakthrough curves for CO₂ adsorption–desorption at concentrations of CO₂ in the gas feed stream of 1%, 3% and 5% at 40 °C and 60 °C.

本手稿的主要目的是研究胺（MEA、DEA 和 TEA）功能化对高表面积载体（Amberlite IR120H、Ambersep 252H、Amberlite 200CNa 和 Amberlite XAD7HP）从气流中吸附 CO _{2 的影响}。实验的饱和因子设计最初用于确定四个胺浸渍变量对胺负载的影响。除了胺浓度对 Amberlite XAD7HP 中浸渍的乙醇胺量有显着影响 ( p  ≤ 0.05) 外，其他因素的重要性可以忽略不计。在不同CO ₂入口浓度的固定床中进行CO ₂吸附动力学实验和温度。在床饱和时，富含 DEA 的Ambersep 252H、Amberlite 200CNa 和Amberlite XAD7HP 上吸附的CO ₂量是使用相同吸附剂而未浸渍的吸附量的40-400 倍。富含 DEA 的 Amberlite IR120H 和 TEA 功能化树脂在研究条件下吸附 CO _{2 的}能力较小，而富含 MEA 的树脂在浸渍于 Amberlite 200CNa 的情况下作为 CO ₂吸附剂是有效的。经典的基本模型正确地描述了在 40 °C 和 60 °C 下气体进料流中CO ₂浓度分别为 1%、3% 和 5% 时CO ₂吸附-解吸的穿透曲线。
