Premium Coconut Shell Activated Carbon from China

Coconut shell activated carbon is widely recognized as one of the most effective filtration and purification media available today. Derived from carefully selected coconut shells, this material undergoes a controlled activation process that creates an incredibly porous structure with a vast internal surface area. The result is a high-performance adsorbent capable of trapping a broad spectrum of impurities from both air and water. Industries ranging from municipal water treatment to food and beverage processing rely on Coconut Shell Activated Carbon for its hardness, purity, and exceptional adsorption capacity. Our Coconut Shell Activated Carbon series includes Gold Recovery Coconut Shell Activated Carbon, Water Treatment Coconut Shell Activated Carbon, and other series.

Understanding the Product Parameters of Coconut Shell Activated Carbon

Every batch of coconut shell activated carbon can be characterized by a set of precise physical and chemical parameters. These values directly influence performance in specific applications. The following breakdown explains the most critical metrics professionals evaluate when selecting a grade for their process.

• Iodine Number (mg/g): Typically ranges from 900 to 1200 mg/g for high-grade material. This measurement indicates the micropore content and is a direct reflection of the carbon’s ability to adsorb small molecular weight compounds.
• Molasses Number: Common values lie between 180 and 350. It represents the mesopore volume, which is crucial for decolorization and the removal of larger organic molecules.
• Surface Area (BET, m²/g): Coconut shell based carbons routinely achieve surface areas ranging from 950 to 1150 m²/g. This expansive network of pores is what gives the material its extraordinary adsorption power.
• Ash Content (%): High-quality coconut shell activated carbon maintains an extremely low ash content, often under 3% and in many WIMICA grades below 1.5%. Low ash ensures minimal impurity leaching into the treated media.
• Moisture Content (%): As packed, moisture is usually kept below 5% to optimize transport weight and preserve adsorption capacity until use.
• Hardness Number (%): Typically above 98%. This mechanical strength prevents excessive fines generation during backwashing and handling, making it ideal for fixed-bed columns.
• Particle Size (Mesh): Common granular sizes include 8x16, 12x40, 20x50, and 4x8 US Mesh. Finer powders, such as 200 or 325 mesh, are also produced for specialized liquid-phase applications.
• pH: The aqueous extract pH is generally neutral to slightly alkaline, typically between 6 and 9, ensuring compatibility with a wide range of water chemistries.
