“As such, the regeneration adsorption performance of the adsorbents were measured, and the regenerability is shown in Fig. 9. After 20 cycles of vacuum pressure swing adsorption, their regeneration performance has reached more than 96.5%. It demonstrates that the ion exchange of La and Ce does not reduce the repetitive adsorption capacity. Moreover, this is a continuous and stable physical adsorption/desorption process. Importantly, this adsorbent is suitable for long-term industrial applications in the adsorption of CO2 gas.”
