About Coal-based Activated Carbon

Purestar coal-based activated carbon is produced from select bituminous coal through controlled carbonization and high-temperature steam activation. The hard, durable granular and pelletized structure is built for fixed-bed, moving-bed and fluidized-bed systems where long bed life, mechanical durability and cost-efficient operation matter. From standard water treatment granules to ultra-low-ash columnar extrusions, high-activity active coke and specialty impregnated desulfurization media, our coal grades cover the full spectrum of industrial adsorption demands.

What Sets This Grade Apart

• High mechanical strength and low attrition extend running cycles and reduce change-out frequency in high-flow municipal and industrial systems
• Cost-effective adsorption capacity for large-volume water and gas treatment operations; coal grades for heavy-duty industrial streams and high-ash-tolerance applications
• Well-developed mesopore and macropore network accelerates mass transfer of large molecular contaminants and supports multiple thermal reactivation cycles
• Custom pelletized, granular and extruded columnar sizes to fit standard and hybrid system configurations, including deep-bed vessels and pneumatic conveying systems

Why Source from Purestar

We manufacture coal-based activated carbon with full traceability from raw bituminous coal sourcing to finished product. Our provincial engineering technology center optimizes activation parameters for each coal seam, ensuring consistent hardness, iodine number and ash control that operators can plan around for scheduled maintenance cycles. Batch consistency is backed by 14 years of production data and rigorous quality gates that reject any lot deviating from specification.
