Volatile organic compounds (VOCs) have become a key goal of air pollution control. These gases emitted from chemical, spraying, printing, and other industries not only harm the environment, but also directly threaten human health. Among the many treatment technologies, activated carbon adsorption has always occupied a central position with its mature, reliable, efficient and flexible characteristics.
The “activity” of activated carbon stems from its unique pore structure. High-quality activated carbon has a well-developed microporous network inside, with a huge specific surface area (usually as high as 1000-1500 square meters/gram), like an invisible molecular-level giant net.
When the VOC exhaust gas passes through the activated carbon bed, the gas molecules are firmly adsorbed on the inner wall of the pore channel under the action ofthe Van der Waals force (physical adsorption) or surface chemical bond (chemical adsorption), thereby realizing the efficient separation and enrichment of pollutants.
When the activated carbon is adsorbed and saturated, the VOC can be released, and the activated carbon can be recovered by methods such as superheating desorbed and steam regeneration to achieve recycling and significantly reduce operating costs.
In the face of VOC exhaust gas with complex composition and changeable concentration, the selection of activated carbon is essential. The main types include：
Kömür granül aktif karbon: made of high-quality anthracite coal as raw material, it has high strength, high adsorption capacity and excellent wear resistance. Its well-developed microporous structure is particularly good at adsorbing small molecular weight VOCs (such as benzene, toluene, xylene and other benzene products), and is the main force in industrial waste gas treatment.
Wood pellet/columnar activated carbon: Using biomass raw materials such as wood or coconut shell, the pore structure is more developed and the proportion of pores is higher. It has excellent adsorption properties and a fast adsorption rate for VOCs with larger molecular weights and slightly higher boiling points (such as ketones, esters, and some chlorine-containing organic matter) and complex mixed gaseous pollutants.
Petek aktif karbon: powdered activated carbon is combined with a special adhesive to make a honeycomb-like structure. Its biggest advantage lies in its very low air resistance (pressure reduction), which is especially suitable for treating large air volume, medium and low concentrations of VOC exhaust gas, and has a significant energy-saving effect.
Special impregnated activated carbon: load specific chemicals (such as potassium permanganate, potassium iodide, metal oxides, etc.) on the surface of activated carbon to enhance the removal ability of specific target pollutants (such as hydrogen sulfide, mercury vapor, acid gases, and some difficult-to-adsorb VOCs) through chemical catalysis or reaction.
