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.
How PL-390/490 Delivers High CTC Coal Pellet Gas Purification
In large-scale VOC abatement systems for automotive painting, composite manufacturing, and pharmaceutical exhaust, bed volume is constrained by existing vessel footprints while regulatory limits remain strict. Standard 60–80% CTC carbons may require deeper beds or more frequent changeouts to maintain compliance, increasing labor and downtime costs.
An extended activation protocol changes the equation. PL-390/490 develops an exceptionally dense micropore network rivaling coconut shell grades in gas-phase capacity while retaining the economic and structural advantages of coal-based extrusion. The CTC >90% rating means more contaminant captured per pound of carbon, directly extending time between regeneration and reducing carbon makeup rates. The pore structure is engineered to resist collapse and blockage during repeated adsorption-desorption cycles, maintaining capacity over extended service life. The 3 mm PL-390 optimizes rapid mass transfer, while the 4 mm PL-490 maximizes carbon mass per vessel volume.
PL-390/490 vs Mid-Tier and 2 mm Premium Coal Pellet Carbons
Mid-tier grades such as PL-380/480 (CTC >80%) deliver strong solvent recovery economics for most industrial applications, yet under sustained peak loading or in space-constrained installations, the additional 10%+ capacity margin of PL-390/490 translates to fewer regenerations and lower total cost of ownership. The 2 mm P-100 offers even higher capacity with faster kinetics, but its smaller diameter generates higher pressure drop and is optimized for cyclic solvent recovery rather than large fixed-bed emission control.
PL-390/490 bridges this gap as a high CTC coal pellet gas purification solution that approaches premium capacity without the premium geometry constraints. The 3 mm and 4 mm diameters maintain manageable pressure drop in large-diameter vessels while the >90% CTC delivers the highest organic vapor loading in the coal columnar range. For petrochemical gas purification, large-scale VOC abatement, and critical catalyst carrier applications where both capacity and bed geometry matter, PL-390/490 provides the optimal balance. Choose PL-380/480 for standard solvent recovery economics; select P-100 for rapid-cycling heavy solvent units; choose high CTC coal pellet gas purification PL-390/490 when maximum capacity per unit volume is required in large fixed-bed installations.
