Activated Carbon Pellets .
Activated carbon pellets (also known as extruded activated carbon or EAC) are cylindrical-shaped forms of activated carbon, typically ranging from 1 to 5 mm in diameter. These pellets are produced by combining powdered activated carbon with a binder, which is then extruded into a cylindrical shape and activated in high-temperature ovens.
Activated carbon pellets are highly effective for gas-phase applications due to their low-pressure drop, high mechanical strength, and larger surface area. They have a uniform shape that allows for easy handling and efficient gas flow.

Key Features of Activated Carbon Pellets:
High Adsorption Capacity: Like other forms of activated carbon, pellets have a high surface area and porous structure, making them ideal for adsorbing gases and vapors.
Low Dust: Due to their mechanical strength, activated carbon pellets produce less dust than granular or powdered forms, making them a preferred choice in sensitive environments.
Long Lifespan: The pelletized form provides high mechanical strength, which allows them to withstand continuous use without breaking down easily.
Low-Pressure Drop: Their cylindrical shape allows for easy flow of gases or liquids through a filtration system with minimal resistance, making them efficient for use in systems requiring high airflow.
Common Applications of Activated Carbon Pellets:
- Air and Gas Purification: Used in air filtration systems to remove contaminants like volatile organic compounds (VOCs), harmful gases, and odors. This includes use in HVAC systems, industrial emissions control, and personal protective equipment (PPE) filters.
- Industrial Gas Processing: Activated carbon pellets are widely used in industries to purify gases such as hydrogen, natural gas, and biogas by removing impurities like sulfur compounds, VOCs, and ammonia.
- Water Treatment: In water purification systems, pellets are effective in adsorbing organic pollutants, chlorine, and other chemicals, although they are more commonly used for gas-phase filtration.
- Solvent Recovery: In industries like printing, coatings, and manufacturing, activated carbon pellets help capture and recover solvents used in production processes, making them more environmentally friendly and cost-effective.
- Gas Masks and Respirators: Due to their high efficiency in removing toxic gases and odors, activated carbon pellets are used in gas masks and respirators, protecting users from hazardous air pollutants.
- Mercury Removal: Pelletized activated carbon is also used in industrial processes to capture mercury emissions from coal-fired power plants and other industrial processes.
