Application of Activated Carbon in CO2 Purification

The application of activated carbon in CO2 purification is mainly based on its excellent adsorption properties. Activated carbon consists of carbon with a highly porous structure and has a large specific surface area, which enables it to effectively adsorb and capture gas molecules, including CO2. Here are some specific applications and advantages of activated carbon in CO2 purification:

Air purification: Activated carbon is widely used in indoor air purifiers to remove CO2 and other harmful gases and improve air quality. It captures CO2 molecules through a physical adsorption process, thereby reducing indoor CO2 concentrations.

Industrial waste gas treatment: In industrial processes, activated carbon can be used in waste gas treatment systems to help remove CO2 from exhaust gases. This is very important for reducing greenhouse gas emissions and meeting environmental regulations.

Energy production and storage: In certain energy production processes, activated carbon can be used to capture and store released CO2. This plays a role in reducing carbon footprint and improving energy efficiency.

Biogas purification: Activated carbon is also used in biogas purification processes. In the process of upgrading biogas (such as biogas) to biomethane, activated carbon is used to remove CO2 and other impurities in it, thereby improving the quality of the fuel.

Water treatment: In some water treatment processes, activated carbon is used to remove carbon dioxide dissolved in water, although this application is more specialized.

Flexibility and renewability: The adsorption capacity of activated carbon allows it to continue to be used after appropriate regeneration. This improves its economic and sustainability in long-term applications.

However, the adsorption efficiency of activated carbon is affected by factors such as temperature, pressure, gas concentration and surface chemistry. Therefore, in specific applications, it may be necessary to modify the surface of activated carbon or select the appropriate activated carbon type according to the use environment to achieve the best effect.
