Granular Activated Carbon
Granular Activated Carbon (GAC) features a larger particle size than powdered carbon, offering high durability and long-lasting performance. It is ideal for applications that require extended contact time, such as air purification, water treatment, deodorization, and flow system separation.
GAC is effective in adsorbing gases, vapors, and organic compounds like chlorine and VOCs. Its structure supports efficient diffusion, making it suitable for both industrial and residential use—including home filtration units, rapid mix basins, and large-scale treatment systems.

Types of granular activated carbon
Coconut shell granular activated carbon
Coconut shell activated carbon, which also named coconut shell activated charcoal, is refined with coconut shell as raw material, and its shape is amorphous particles. It has the characteristics of high mechanical strength, developed pore structure, large specific surface area, fast adsorption speed, high adsorption capacity, easy regeneration and durability.
Nut shell Granular Activated Carbon
Tongke nut shell granular activated carbon is made from palm shell , peach shell,apricot kernel. They are featured with low ash, high strength, high CTC, economical and practical. It widely applied in the treatment of water, food purification, and gold recovery.
Coal Based Granular Activated Carbon
Coal-based granular activated carbon is made of high-quality anthracite and tar, and is processed and refined using advanced technology. It has the appearance of black columnar particles. It has the characteristics of developed porosity, large specific surface area, strong adsorption capacity, high mechanical strength, easy repeated regeneration, and low cost. It is widely used in toxic gas purification, waste gas treatment, industrial and domestic water purification, solvent recovery, etc.

Advantage of granular activated carbon
Activated carbon is a porous, non-crystalline adsorbent produced by carbonizing and activating carbonaceous materials. It is categorized by shape into powdered (PAC) and granular (GAC) forms.PAC, typically made from wood, often faces issues like filter clogging and difficult powder separation, limiting its use in some industries. As a result, GAC has gained greater prominence. With its defined shape, high mechanical strength, and low dust emission, GAC offers significant advantages in handling, storage, and application, making it suitable for diverse industrial requirements.

Application of granular activated carbon
Water Treatment
Granular activated carbon for water treatment is mainly used to remove pollutants in scenarios such as drinking water, industrial wastewater, sewage treatment, and swimming pools, including volatile organic compounds (VOCs), disinfection by-products (DBP), chlorinated compounds, chloramines, hydrocarbons, heavy metals, colloids, toxins, oils, and many other pollutants.
Food and Beverage
Utilized for removing impurities such as color and odor from food liquids, syrups, organic acids, amino acids, vitamins, alcoholic beverages, and glycerol.
Gold Recovery
Provides high iodine 6-12, 8-16 mesh coconut shell granular carbon for quick and efficient recovery of precious metals, releasing gold.
Solvent Recovery
Offers activated carbon for high-end air purification or various gas solvent recovery, such as gases like benzene and toluene.
Catalyst Carrier
Research and production of activated carbon as a catalyst and carrier have gained widespread industrial applications, serving as a carrier for catalysts degrading hydrogen sulfide and precious metal catalysts.
Gas Treatment
Activated carbon granules can remove pollutants in the air, such as toxic volatile organic compounds (VOCs) from air emission sources.
Mercury Removal
Used for the outstanding adsorption performance in purifying liquid natural gas.
