Columnar activated carbon
Overview
Columnar activated carbon, also known as extruded pellet activated carbon, is a premium adsorbent material derived primarily from high-quality anthracite coal or wood-based sources. It features a cylindrical shape that optimizes flow dynamics and adsorption efficiency in industrial purification systems. This product is engineered for demanding B2B applications where reliability and performance are critical, ensuring effective contaminant removal while maintaining operational integrity.
Features
- Cylindrical pellets with diameters ranging from 1-8 mm for low pressure drop and uniform flow.
- High surface area (typically 800-1100 m²/g) with a balanced micro/meso pore structure for enhanced adsorption.
- Superior hardness (>93%) to withstand mechanical stress in fixed-bed systems.
- Low ash and moisture content for minimal impurities and extended service life.
Applications
- Gas purification, including VOC removal, solvent recovery, and odor control in manufacturing and petrochemical facilities.
- Water treatment for polishing, dechlorination, and organic contaminant reduction in industrial and municipal systems (certification required for potable use).
- Biogas upgrading by removing H2S and siloxanes.
- Desulfurization and denitration pretreatment in environmental control systems.
Advantages
- Reduced pressure drop compared to irregular shapes, improving energy efficiency in air and gas streams.
- High mechanical strength minimizes dust generation and bed collapse, lowering maintenance costs.
- Versatile regeneration potential, allowing multiple cycles for cost-effective operations.
- Compliance with international testing standards, facilitating global trade and buyer confidence.

Customer Reviews
We switched to YONGRUIDA for the activated carbon in our municipal water treatment facility, and the consistency has been remarkable. Their product reliably meets specifications batch after batch, which is critical for our compliance. The Certificate of Analysis with every shipment gives us complete peace of mind.
— David Chen
The technical support from the YONGRUIDA team was invaluable. They analyzed our wastewater stream and recommended a specific grade of GAC that increased our contaminant removal efficiency by over 20%. They are more than a supplier; they are a genuine partner in solving our operational challenges.
