Coal-Based Granular Activated Carbon for Air Purification – High-Efficiency Gas Phase Filtration
Product Name: Coal-Based Granular Activated Carbon (GAC)
Raw Material: Premium Bituminous Coal / Anthracite
Keywords: Air Purification Carbon, Gas Phase Carbon, VOC Removal, Odor Control, Solvent Recovery, Impregnated Carbon, HVAC Filtration
Product Overview
Ensure cleaner air and regulatory compliance with our Coal-Based Granular Activated Carbon (GAC). Specifically engineered for gas-phase applications, this carbon features a highly developed microporous structure and a large specific surface area, making it the premier choice for removing Volatile Organic Compounds (VOCs), toxic gases, and odors.
Its superior mechanical strength and low pressure drop characteristics make it ideal for industrial scrubbers, HVAC systems, and solvent recovery units. Whether treating complex chemical fumes or general indoor air, our coal-based GAC delivers reliable, high-capacity adsorption performance.
Key Advantages
- High Adsorption Capacity: Optimized pore structure provides rapid adsorption kinetics for a wide range of organic vapors and hazardous air pollutants.
- Exceptional Mechanical Strength: High hardness (>95%) ensures the carbon withstands vibration and airflow pressure without generating dust, which is critical for maintaining low pressure drops in packed beds.
- Versatile & Cost-Effective: Offers a superior balance of performance and price for large-scale industrial gas treatment compared to other carbon types.
- Impregnation Ready: The high-quality coal base is an excellent substrate for chemical impregnation (e.g., with KOH, KMnO₄) to target specific acidic gases (H₂S, SO₂) or mercury.

Applications
Industrial Air Purification:
Widely used in chemical plants, refineries, and paint booths to capture VOCs, benzene, toluene, and xylene, ensuring compliance with environmental emission standards.Solvent Recovery:
Essential in industries using organic solvents (printing, coating, rubber). The carbon adsorbs solvent vapors from the airstream, which are then desorbed and recovered, reducing raw material costs.Odor Control Systems:
Effective in removing malodorous compounds (such as mercaptans and amines) from wastewater treatment plants, food processing facilities, and composting operations.HVAC & Indoor Air Quality:
Used in commercial and residential air handling units to remove indoor pollutants, cigarette smoke, and formaldehyde, improving overall air quality.Flue Gas Desulfurization (FGD):
Specialized grades act as catalysts or adsorbents for removing sulfur dioxide (SO₂) and nitrogen oxides (NOx) from power plant emissions.
Packaging & Storage
- Packaging: 25kg or 500kg woven bags with PE liners to prevent moisture absorption.
- Storage: Store in a cool, dry, and well-ventilated area. Keep away from strong oxidants and flammable materials.
