Selecting the appropriate activated carbon product is crucial for achieving optimal results in purification processes. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of high-quality activated carbon solutions, including extruded pellets and granular forms, each with distinct advantages. Understanding the differences between these product forms and the impact of raw material selection is key to making an informed choice.

Extruded Activated Carbon Pellets: These are manufactured by mixing powdered activated carbon with a binder and extruding it into uniform cylindrical pellets. This process imparts several beneficial characteristics:

  • Uniformity and Predictable Flow: The consistent shape and size ensure predictable flow paths in filters, leading to lower pressure drops and more efficient contact with contaminants. This is highly advantageous in gas-phase applications where controlled airflow is critical.
  • High Mechanical Strength: The extrusion process enhances the pellet's resistance to physical degradation, making them durable for industrial use.
  • Reduced Dust Generation: Compared to some granular forms, extruded pellets tend to produce less dust, which is beneficial for handling and system maintenance.
  • Applications: Extruded activated carbon is widely used in air purification, solvent recovery, biogas desulfurization, and other gas treatment processes.

Granular Activated Carbon (GAC): GAC consists of irregularly shaped particles formed from screening carbonized materials. Its characteristics include:

  • Varied Particle Sizes: GAC is available in a wide range of particle sizes, offering flexibility for different filter designs and flow rates.
  • High Surface Area: Like all activated carbons, GAC offers a high surface area for adsorption.
  • Applications: GAC is predominantly used in water treatment due to its effectiveness in adsorbing dissolved organic compounds, chlorine, and other impurities from liquids. It is also used in some air filtration applications.

Raw Material Considerations: The source material for activated carbon significantly influences its pore structure and, consequently, its adsorption properties. NINGBO INNO PHARMCHEM CO.,LTD. utilizes high-quality coal and coconut shells:

  • Coal-based Activated Carbon: Typically produces activated carbon with a high proportion of micropores, making it excellent for adsorbing small gas molecules and for applications requiring high strength and low pressure drop, such as extruded pellets for air purification.
  • Coconut Shell-based Activated Carbon: Known for producing activated carbon with a high proportion of micropores (< 2 nm), which is highly effective for gas-phase applications, including air purification, and certain water purification processes. It generally offers superior hardness and lower ash content.

NINGBO INNO PHARMCHEM CO.,LTD. provides detailed specifications for their products, including particle size, CTC values, surface area, and ash content, allowing customers to make informed decisions based on their specific purification requirements. Whether for air filtration, water treatment, or industrial gas processing, their range of activated carbon products ensures efficient and cost-effective solutions.
