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.
How PLC-370/470 Achieves Coconut Shell Columnar Carbon Air Gas Purification
Air purification and and Chemical Processing applications frequently present a dilemma: coconut shell granules deliver unmatched purity for natural gas treatment and industrial VOC treatment, yet their irregular shapes trigger channeling and uneven pressure drop. Coal-based pellets provide geometric consistency for solvent recovery and catalyst carrier duties, but their elevated ash and leachable metals risk contaminating sensitive processes. Crushing premium coconut shell charcoal, re-agglomerating with binder, and activating with high-temperature steam creates true extruded pellets that merge both advantages.
The coconut shell base provides inherently lower ash and fewer leachable metals than coal alternatives, while the engineered 3 mm and 4 mm geometry ensures uniform bed packing and predictable flow dynamics. The CTC >70% delivers robust capacity for general air purification, light solvent recovery, and catalyst support without the cost premium of ultra-high-activity grades. The natural coconut shell hardness (>90%) resists attrition during pneumatic conveying and bed loading.
PLC-370/470 vs Coal Pellet and Coconut Shell Granular Carbons
Coal pellet grades such as PL-360/460 or PL-380/480 offer higher CTC ratings (60–80%+) at lower cost for heavy-duty industrial exhaust, yet their higher ash content can poison precious metal catalysts or introduce contaminants in food-grade CO₂ and cleanroom applications. Coconut shell granular grades such as CTC-100 or CFV 4×8 provide exceptional purity and hardness, but their irregular particle shape can cause channeling and uneven flow distribution in fixed-bed reactors where predictable pressure drop is essential for blower sizing.
PLC-370/470 bridges this gap as a coconut shell columnar carbon air gas purification grade that combines the best attributes of both material classes. The extruded pellet geometry eliminates the flow irregularities of granular media while the coconut shell base maintains the low ash and high purity required for sensitive applications. Compared to coal pellets, the lower ash reduces heat generation during solvent recovery desorption, cutting steam consumption. Compared to irregular granules, the uniform sizing ensures consistent bed packing. Choose coal columnar for maximum CTC at minimum cost; select coconut shell granular for deep-bed low-pressure-drop systems; choose coconut shell columnar carbon air gas purification PLC-370/470 when pellet uniformity and coconut shell purity must coexist.
