This work comprehensively investigated the effect of oxygen in the air on the selectivity of polyamine-functionalized adsorbents towards CO2 in the adsorption process and the oxidative stability in the desorption process. Results indicate high selectivity toward CO2 and oxidative resistance of adsorbents can be realized by accurately controlling the operating temperature.
