Heycarbons Coal Granular Activated Carbon GAC Manufacturer From China
What is Coal-based Granular Activated Carbon GAC?
Coal-based granular activated carbon is a porous adsorption material made from high-quality coal from Datong, Shanxi, Xinjiang and Ningxia, through carbonization and activation processes. It has a high proportion of mesopores and also features high mechanical strength, cost advantages, and recyclability.
Shanxi and Xinjiang primarily produce bituminous coal, while Ningxia produces anthracite.
As an economical and efficient adsorption material, coal-based granular activated carbon is widely used in industrial gas purification, VOC removal, and wastewater treatment. It is especially suitable for systems with high pollution loads and continuous operation.
Common particle sizes of coal granular activated carbon include: 4*8, 5*10, 6*12, 8*16, 8*30, 12*40, 30*60, and 80*150 mesh.
How is Coal-based Granular Activated Carbon Produced?
Heycarbons, a professional manufacturer of coal-based granular activated carbon, employs the following key steps in its production process:
Raw Material: High-quality bituminous or anthracite coal is selected (Bituminous coal is used more frequently than anthracite).
Process: After impurities are removed, the raw material is heated and carbonized under air-isolated conditions (typically 400-700℃) to form a preliminary porous structure.
Subsequently, physical steam activation (typically 900-1200℃) is performed, expanding and opening the pores formed during carbonization to create well-developed micropores and mesopores, thereby achieving a large specific surface area and adsorption capacity.
After cooling at room temperature, the activated carbon undergoes crushing, sieving, and dust removal to obtain the finished coal-based granular activated carbon product.
The following processing can also be performed according to the actual application scenario:
- Acid washing of carbon to reduce ash content.
- Impregnation with alkaline, acidic, or metal oxides to achieve targeted removal of specific contaminants.
Packaging can then be done according to customer requirements.
Anthracite VS Bituminous Coal Activated Carbon
In terms of raw materials, bituminous coal and anthracite each have their own characteristics in terms of strength and pore structure. In the application of coal-based granular activated carbon, is bituminous coal more suitable or anthracite more advantageous? What performance differences do different coal types bring? These questions can be answered more deeply in:

Coal Granulated Activated Carbon Advantages and Disadvantages
Coal Granular Activated Carbon Advantages
- High mechanical strength, not easily pulverized, wear-resistant and long service life.
- More cost-effective than coconut shell activated carbon in large-scale water treatment.
- In liquid-phase adsorption, granular activated carbon has a smaller particle size and a larger contact area compared to pelletized activated carbon. Therefore, it has a faster and more uniform adsorption efficiency.
- Compared to coal briquettes carbon, coal granular carbon has a higher methylene blue content, although their iodine value is not the highest (IV 1050~1100 mg/g). Methylene blue content can reach 240, and CTC can reach 60.
- Customuize size distribution: Heycarbons can customize the particle size distribution of granular activated carbon according to equipment operating conditions to achieve precise matching with flow rate. This reduces pressure drop and mass transfer resistance, thereby extending the operating cycle and improving overall adsorption performance.
- Easy to handle and regenerate: The particulate form makes it easy to fill and use in adsorption devices such as fixed beds and fluidized beds. After saturation, it can be regenerated through thermal activation for repeated use.
Coal Granulated Activated Carbon Disadvantages
- Compared to coconut shell charcoal, coal carbon has a higher ash content, a lower proportion of micropores, and a weaker ability to adsorb small molecules.
- GAC’s strength is lower than EAC’s, but it’s cheaper.

Coal-based Granular Activated Carbon Applications
Granular Activated Carbon Wastewater Treatment
In industrial water treatment systems, coal-based granular activated carbon (IV 500-1050 mg/g) is widely used in the advanced treatment stage, effectively removing COD, BOD, PFAS, heavy metal ions, organic pollutants, and color. It is suitable for chemical wastewater, dyeing and printing wastewater, pharmaceutical wastewater, and other industrial wastewater applications. It can also be used for municipal wastewater.
Coal-based granular activated carbon has a large adsorption capacity, stable operation, is suitable for continuous filtration systems, and offers cost advantages.
Drinking Water Treatment
At the upstream of drinking water treatment, waterworks and community water stations often use coal-based granular activated carbon for filtration to remove pollutants such as organic matter, residual chlorine, and heavy metal ions from the water.
GAC Granular Activated Carbon for Water Filter
Heycarbons could provide high-iodine-value granular activated carbon (low ash, 8*16/8*30/12*40/30*60/50*150 mesh) for CTO and UDF filter cartridges.
Solvent Recovery
In the chemical and pharmaceutical industries, coal-based granular activated carbon can be used for organic solvent recovery (aromatic hydrocarbons, halogenated solvents, esters, etc.) and VOCs adsorption.
Amine Purification
In the purification of amine solutions such as MDEA and MEA, IV900 coal-based granular activated carbon can be used to absorb and remove hydrocarbons, heat-stable salts (HSS), remove degradation products, purify amine solutions, reduce foaming, and lower system corrosion.
Flue Gas Desulfurization and Denitrification
In addition to columnar activated carbon, some clients also opt to use granular activated carbon for applications such as industrial flue gas desulfurization and denitrification, SO2 adsorption, and NOx removal. It can be used for flue gas treatment in power plants, steel plants, cement plants, oil refineries, waste incineration plants, etc.
