Carbon dioxide adsorbents are materials that are used to remove or “adsorb” carbon dioxide (CO2) from the air or other gas streams. They are commonly used in a variety of applications, including air purification, gas separation, and carbon capture and storage.

There are several types of CO2 adsorbents, including:

Solid sorbents – materials such as activated carbon, zeolites, and metal-organic frameworks (MOFs) that have a high surface area and can physically adsorb CO2 molecules.

Liquid sorbents – solvents such as amines, amine blends, and ionic liquids that chemically react with CO2 to form stable compounds.

Hybrid sorbents – materials that combine both physical and chemical adsorption mechanisms to capture CO2.

CO2 adsorbents can be used in a variety of applications, including:
