Activated carbon for air and gas treatment
Activated carbon can be used in its pure state to remove organic contaminants from air and gases, or impregnated to retain gaseous contaminants not retained by a standard activated carbon, these carbons are chemically impregnated, for
acid gases, organic vapors, mercury vapors, ammonia vapors and low molecular weight amines.
Chemically modified activated carbons complement the natural functions not covered by a conventional activated carbon to retain other compounds. This enhances the neutralization and adsorption of an activated carbon.

Applications of Air & Gas Activated Carbon
Waste Incineration Flue Gas Treatment
Flue gases from waste incineration contain multiple toxic and hazardous substances. Direct emission poses serious risks to the environment and human health. Thanks to its high specific surface area and strong adsorption capacity, activated carbon serves as a key material in flue gas purification systems, enabling efficient emission reduction.
Tongke’s activated carbon effectively removes Pollutants like Dioxins, acid gases, volatile organic compounds (VOCs), heavy metal vapors
Waste Landfill Gas Treatment
Hazardous waste landfills release sulfur/nitrogen compounds, VOCs, and odorous gases during long-term storage. These gases feature complex composition, fluctuating concentrations, and significant toxicity. Activated carbon, with its broad-spectrum adsorption capacity and potential for surface modification, provides an efficient solution for landfill gas purification, simultaneously addressing pollutant removal and odor control.
Tongke’s activated carbon effectively removes pollutants like Odorous substances, toxic VOCs, greenhouse gases, heavy metal vapors
Specialized Gas-Phase Carbon for Livestock Farming
Activated carbon is vital in livestock farming for treating both gaseous and liquid streams. In gas-phase applications, it primarily purifies ventilation exhaust from animal housing and biogas by adsorbing odorous gases like NH₃ and H₂S, as well as VOCs.
Agricultural Waste Gas Treatment
In the pesticide industry, activated carbon addresses complex challenges of high-toxicity, multi-component pollutants through process innovation and functional modification. Driven by the "New Pollutant Treatment Action Plan," the technology is evolving towards precision adsorption and low-carbon regeneration, supporting the industry's green transition.
We supply high-efficiency extruded activated carbon (EAC) and powder activated carbon (PAC )to remove Pollutants like VOCs, acid gases, odorous substances, particulate matter, high-toxicity compounds
Air Purifiers
As indoor decoration pollution and airborne particulate issues become increasingly prominent, activated carbon filters have emerged as a core component in modern air purification systems, with their adsorption performance directly determining purification efficiency and user health.
Indoor pollutants often from Indoor renovation pollutants (formaldehyde, benzene series), household air purification, airborne particulates (PM2.5, pollen), pet odors (organic amines, sulfides).
Activated carbon help remove indoor pollutants like Formaldehyde, benzene series, cooking fumes, TVOC, room odor molecules, bacteria, and microorganisms.
Refrigerator Deodorizing
Odors and microbial growth caused by food spoilage and humid environments pose key health risks in refrigerators. Activated carbon modules address these issues through efficient adsorption and antimicrobial functions.
