This 4mm coal-based pellet activated carbon is engineered for professional gas-phase adsorption and purification. Featuring uniform particle size, well-developed micropore structure and powerful adsorption performance, it is manufactured from premium coal materials with advanced activation techniques. Boasts high mechanical strength, low ash content and anti-powdering properties, ensuring stable and long-term operation. Specially optimized for efficient removal of toluene, VOCs and other industrial harmful waste gas, the product offers high adsorption saturation and outstanding durability. Ideal for industrial waste gas treatment and air purification systems, it provides stable, cost-effective and high-efficiency environmental purification solutions.

Yihang 4mm coal-based pellet activated carbon is manufactured from high-quality coal feedstock using advanced activation processes, creating a highly porous internal structure with an extremely large effective surface area. This gives the carbon exceptional adsorption capacity, making it ideal for capturing toluene, VOCs, and other gaseous contaminants in industrial waste gas streams.
Thanks to its well-developed micropore structure and consistent pellet form, this activated carbon delivers reliable performance in gas-phase adsorption systems. The 4mm extruded pellets offer excellent mechanical strength and low dusting, ensuring stable, long-lasting operation in various air purification and emission control applications.
Tailored for the removal of volatile organic compounds (VOCs) including toluene, this carbon provides high adsorption efficiency and saturation capacity, supporting cost-effective, sustainable gas treatment solutions.
