Zeolites as Selective Adsorbents for CO₂ Separation

Zeolites are a very versatile class of materials that can display selective CO2 adsorption behavior and thus find applications in carbon capture, storage, utilization (CCSU). In this contribution, the properties zeolites as adsorbents reviewed by critically presenting discussing their assets limitations. For purpose, we first provide an overview mechanisms on different types zeolites. Then, systematically discuss relationship between physicochemical (framework type, Si/Al ratio, extra-framework cations) performance for separation CO2/CH4 (biogas) CO2/N2 (flue gas) mixtures. Based trends identified, comparison highlight advantages drawbacks applicability adsorption. Finally, present state art shaping macroscopic format, which is key step toward industrial adsorbents.
