Case Details
Due to its highly developed pore structure and large specific surface area, activated carbon has become a core material in the field of waste gas treatment, and is widely used in industrial and environmental protection scenarios. Its core role is to capture harmful components in waste gas by combining physical adsorption and chemical adsorption.
Physical adsorption relies on van der Waals forces within the pore structure, effectively capturing volatile organic compounds (VOCs) like benzene and toluene, as well as toxic gases such as formaldehyde and acetone. These substances readily adhere to the pores of activated carbon. Chemical adsorption, on the other hand, works by reacting surface functional groups with exhaust components, thereby immobilizing acidic or alkaline emissions including hydrogen sulfide and nitrogen oxides.
In practical applications, activated carbon is commonly produced in granular or honeycomb forms for use in adsorption towers and similar equipment. For instance, chemical plants utilize it to treat production exhaust gases, while furniture factories employ it to purify spray painting emissions. In automotive exhaust treatment, honeycomb activated carbon assists in filtering harmful components. Regenerated activated carbon after saturation can be reused, which not only reduces costs but also minimizes solid waste pollution, thereby contributing to environmental protection and resource recycling.
