Product Overview
PL-380 and PL-480 are high-performance coal-based columnar activated carbons engineered for solvent recovery, organic gas purification, and catalytic support applications where adsorption capacity directly impacts process economics. With CTC activity exceeding 80%, these pellets deliver extensive micropore volume for capturing a broad spectrum of organic vapors including hydrocarbons, alcohols, esters, and ketones.
Manufactured through precision extrusion of powdered bituminous coal followed by controlled high-temperature steam activation, the 3 mm PL-380 and 4 mm PL-480 combine high surface area with exceptional mechanical strength. The elevated CTC rating enables longer adsorption cycles in solvent recovery units, reducing steam consumption for regeneration and maximizing product recovery per pound of carbon.
Key application areas
- Solvent Recovery Systems — Adsorbs organic solvents from process air in printing, coating, and chemical manufacturing, enabling distillation and reuse with minimal carbon replacement.
- Oil & Gas Vapor Recovery — Captures hydrocarbon vapors from storage tank vents, loading racks, and pipeline operations, reducing product loss and emission violations.
- Catalytic Support & Gas Purification — Serves as a high-purity substrate for catalysts in petrochemical reforming and environmental oxidation systems, where uniform pellet geometry ensures consistent reactor performance.
- Organic Gas Treatment — Removes concentrated organic vapors from polymer processing, adhesive curing, and resin manufacturing exhaust streams.
- Chemical Process Gas Purification — Polishes feed gases and removes trace organics in synthetic chemical production, protecting sensitive catalysts and product quality.

How PL-380/480 Enables Coal Columnar Carbon Solvent Recovery
Solvent recovery operations demand carbon that captures enough organic vapor per cycle to justify the capital investment in distillation and reactivation infrastructure. When adsorption capacity is insufficient, cycles shorten, steam consumption rises, and recovered solvent yields fail to offset operating costs.
PL-380/480 solves this through optimized high-temperature steam activation that develops extensive micropore volume specifically tuned for gas-phase organic capture. The CTC >80% rating indicates robust capacity for medium-to-high molecular weight solvents including toluene, xylene, butanol, and acetate esters. The 3 mm PL-380 reaches equilibrium faster due to shorter internal diffusion paths, making it ideal for rapid-cycling units with short contact times. The 4 mm PL-480 maximizes bed density in large fixed-bed reactors, reducing vessel footprint per unit of adsorption capacity. The >90% hardness ensures pellets survive repeated steam reactivation with minimal attrition, preserving bed integrity across multiple cycles.
PL-380/480 vs Lower-Activity and Premium Coal Pellet Carbons
Lower-activity grades such as PL-360/460 (CTC >60%) or PL-350/450 (CTC >50%) deliver reliable VOC removal for exhaust and odor control but lack the micropore volume needed for economical solvent recovery, requiring more frequent regeneration and reducing net solvent yield. At the premium end, P-100 (CTC >100%) offers maximum capacity in a 2 mm pellet optimized for heavy solvent loads, yet its higher cost and smaller diameter may not be necessary for mid-range solvent recovery or oil & gas vapor capture.
PL-380/480 bridges this gap as a coal columnar carbon solvent recovery grade that balances high capacity with practical economics. The 80% CTC threshold captures sufficient solvent per cycle to support profitable recovery operations while the coal-based manufacturing maintains lower cost than equivalent coconut shell grades. The dual-diameter option allows process engineers to optimize for kinetics (3 mm) or bed density (4 mm) without changing carbon chemistry. Choose PL-360/460 for general VOC abatement without recovery; select P-100 for maximum-capacity heavy solvent duty; choose coal columnar carbon solvent recovery PL-380/480 for regenerable solvent recovery, oil & gas vapor capture, and catalytic support where capacity and cost must align.
