Shell Activated Carbon[3]
Overview
Shell Activated Carbon is a premium-grade adsorbent produced through the carbonization and activation of coconut shells. Its unique microporous structure and high surface area make it ideal for trapping impurities and contaminants. Unlike coal-based alternatives, it offers superior hardness, lower ash content, and renewable sourcing. The material is widely favored in industries requiring high-purity adsorption, such as potable water treatment and food processing. Its eco-friendly origin and efficient regeneration potential further enhance its appeal in sustainable industrial practices.
Physical and Chemical Properties
Shell Activated Carbon exhibits a surface area of 800-1200 m²/g, with micropores dominating its structure for optimal adsorption of small molecules. Its density ranges from 0.4-0.6 g/cm³, and it remains chemically inert under normal conditions. The carbon’s hardness (Mohs scale 3-4) minimizes attrition losses in flow systems, while its low ash content (<5%) ensures minimal interference in sensitive applications like pharmaceuticals. Its thermal stability allows regeneration at 600-900°C without significant performance degradation.
Main Applications
In water treatment, Shell Activated Carbon removes chlorine, organic compounds, and heavy metals. Municipal plants and household filters extensively use it for potable water purification. Industrial applications include solvent recovery in printing and painting industries, VOC abatement in air scrubbers, and gold adsorption in mining. Its medical uses span poison antidote capsules and dialysis filters due to its biocompatibility.
Safety and Storage
While non-toxic, airborne carbon dust requires NIOSH-approved respirators during bulk handling. Static electricity buildup during transport necessitates grounded containers. Storage should avoid humid environments to prevent pore clogging. Bulk bags must be stacked vertically to prevent compaction. Spills are non-hazardous but should be cleaned promptly to reduce slip risks.
B2B Procurement Guide
Buyers should prioritize suppliers providing detailed specifications like iodine number (>1000 mg/g for high-end uses) and particle size distribution (e.g., 8x30 mesh for gaseous applications). Consider MOQ flexibility and bulk discounts for 20+ ton orders. ISO 9001-certified manufacturers ensure consistent quality. Sample testing for adsorption kinetics is recommended before large purchases.
