Activated Carbon – VOC and Odor Adsorption

Activated Carbon is an adsorbent material with a highly developed pore structure and large Specific Surface Area, primarily removing Pollutants from gases or liquids through Physical Adsorption and Surface Chemical Interactions.

Activated Carbon is typically produced from carbonaceous materials such as coconut shells, coal, and wood through an activation process. After specialized processing, a large number of micropores, mesopores, and macropores are formed internally, providing abundant adsorption sites that capture pollutant molecules on the carbon material surface.

In the field of industrial air pollution control, Activated Carbon is primarily used to adsorb VOCs, odorous gases, and certain harmful gases, and is widely used in exhaust gas treatment, air purification, wastewater treatment, and industrial filtration systems.
