Product Overview
PLC-370 and PLC-470 are coconut shell-based columnar activated carbons that combine the natural hardness and purity of coconut shell with the engineered geometry of extruded pellets. Manufactured by crushing premium coconut shell charcoal, re-agglomerating with binder, and activating with high-temperature steam, these pellets achieve CTC activity above 70% with exceptional mechanical strength.
The coconut shell base provides inherently lower ash and fewer leachable metals than coal-based alternatives, making this series ideal for applications where carbon purity influences process outcomes. The 3 mm PLC-370 and 4 mm PLC-470 serve air purification, gas treatment, and catalytic support markets requiring a balance of adsorption capacity, structural integrity, and material cleanliness.

Key Application Areas
- Commercial & Industrial Air Purification — Removes VOCs, acetone, carbon disulfide, odors, and trace contaminants from HVAC systems, cleanrooms, and process building ventilation.
- CO₂ Gas Purification — Polishes carbon dioxide streams for food-grade and industrial gas applications by adsorbing residual hydrocarbons and sulfur compounds.
- Low-Boiling-Point Solvent Recovery — Captures and recycles low-boiling-point solvents, acetone and carbon disulfide from air streams in pharmaceutical and electronics manufacturing.
- Catalyst Support — Serves as a high-purity carrier for catalytic materials in environmental and chemical processing applications where low ash preserves catalyst activity.
- Chemical Processing Gas Treatment — Purifies process and vent gases containing acetone and carbon disulfide for specialty chemical, petrochemical, and fine chemical production.
Key Advantage
- Coconut Shell Purity Advantage: Lower inherent ash and metal content compared to coal-based pellets reduces the risk of catalyst poisoning and process contamination in sensitive applications.
- High Hardness for Handling: >90% crush strength and natural coconut shell density resist attrition during pneumatic conveying, bed loading, and backwashing operations.
- Balanced CTC Performance: >70% CTC provides robust capacity for general air purification and light solvent recovery without the cost premium of ultra-high-activity grades. Its low ash feature leads to low heat generation during solvent recovery processes, which effectively cuts down steam consumption for desorption.
- Engineered Pellet Geometry: Uniform 3 mm and 4 mm extrusions ensure consistent bed packing, low channeling, and predictable pressure drop in fixed-bed reactors and filters.
