Product Overview
PL-390 and PL-490 represent the peak performance tier of our coal columnar series, delivering CTC activity above 90% for the most demanding gas-phase adsorption applications. These pellets are engineered for industrial users who require maximum organic vapor capacity per unit volume—whether for high-value solvent recovery, critical gas purification, or large-scale emission control systems.
The extended activation protocol develops an extensive micropore network that rivals coconut shell grades in gas-phase capacity while retaining the economic and structural advantages of coal-based extrusion. Available in 3 mm (PL-390) and 4 mm (PL-490) diameters, this grade minimizes total cost of ownership in cyclic adsorption processes by extending time between regeneration and reducing carbon makeup rates.

Key application areas
- High-Value Solvent Recovery — Maximizes capture of expensive solvents from pharmaceutical and electronics manufacturing exhaust, delivering rapid payback on carbon investment.
- Petrochemical Gas Purification — Removes trace organics and sulfur compounds from process gas streams in refineries and chemical plants, protecting downstream catalysts and product specifications.
- Large-Scale VOC Abatement — Serves high-volume emission control systems for automotive painting, composite manufacturing, and industrial baking where extended cycle times reduce operating labor.
- Catalyst Carrier for Fine Chemicals — Provides ultra-high surface area and controlled pore distribution for precious metal catalysts in hydrogenation, oxidation, and polymerization reactions.
- Critical Gas Storage & Pipeline Treatment — Purifies natural gas, hydrogen, and industrial gas streams before storage or transmission, ensuring compliance with strict purity standards.
Key Advantages
- Maximum CTC Capacity: >90% CTC delivers the highest organic vapor loading per pound in the coal columnar range, directly reducing regeneration frequency and carbon consumption.
- Optimized for Cyclic Operations: The pore structure is engineered to resist collapse and blockage during repeated adsorption-desorption cycles, maintaining capacity over extended service life.
- Precision Extrusion Consistency: Tight dimensional control on 3 mm and 4 mm pellets ensures uniform bed packing and predictable pressure drop across large-diameter vessels.
- Cost-Effective Premium Performance: Delivers gas-phase capacity approaching specialty coconut shell grades at a coal-based price point, optimizing capital efficiency for large installations.
