This series of activated carbons are activated carbons with high adsorption and high desorption performance made by special process, and have extremely high specific surface area. The appearance of this series of activated carbon can be cylindrical or irregular. It has strong adsorption recovery and separation performance for organic solvents such as ethers, ketones, alcohols, chlorohydrocarbons, fluorocarbons, aromatics, gasoline and their vapors. Widely used in the treatment of volatile organic waste gas (VOCs) in various chemical plants, such as paint, coating spraying workshop, dye factory, vehicle manufacturing factory, printing factory, tape factory and petrochemical system, oil depot, gas station and other industries.
