Granular Nut shell activated carbon
NC-AC800-1000 is produced from renewable agricultural wastes such as coconut shells, walnut shells, or apricot pits through carbonization and steam activation. It features a highly developed microporous structure with surface areas reaching 1000 m²/g and iodine values exceeding 1000 mg/g. This carbon grade is renowned for its exceptional hardness (95–98%), ultra-low ash content, and uniform particle size distribution. These properties make it ideal for potable water treatment, gold recovery in CIL circuits, gas purification, and respirator applications. Its renewable origin, high adsorption capacity, and excellent regeneration performance offer a sustainable, cost-effective solution for diverse environmental and industrial purification needs.

Working principle
Shell-based granular activated carbon is produced from renewable agricultural shells (coconut, walnut, or apricot) through carbonization and high-temperature steam activation. The irregular granular shape provides high external surface area for rapid mass transfer. Contaminants—such as organic compounds, chlorine, VOCs, and gold cyanide complexes—are captured through physical van der Waals forces within the micropores. Additionally, oxygen-containing functional groups on the carbon surface enable chemisorption for polar molecules, enhancing removal efficiency in both liquid and gas phases.

Product Advantages
1.Uniform Particle Size: Narrow mesh distribution (e.g., 8×30 or 12×40 mesh) ensures consistent flow dynamics, prevents channeling, and optimizes contact time in fixed-bed filters. 2.Excellent Regeneration: Steam or thermal regeneration restores 90–95% of original activity, enabling multiple reuse cycles without significant performance loss. 3.Versatile Applications: Effective across water treatment, gold recovery, gas purification, solvent recovery, and respirator cartridges.

Have Questions? We're Here to Help.
Identify the pollutants to be adsorbed; examine key indicators; and conduct small-scale trials to verify the results, taking into account cost.
No. The iodine value only indicates the number of micropores and is suitable for small molecules; if processing large molecules, the methylene blue value and the proportion of mesopores need to be considered.
Drinking water/odor removal: Coconut shell charcoal (high micropores); Municipal high-flow-rate charcoal: Coal-based charcoal (high strength); Industrial wastewater decolorization: Wood-based charcoal (well-developed mesopores); Specific selection requires flexibility.
Granular activated carbon (general purpose), honeycomb activated carbon (high airflow, low resistance), and fiber felt (high-requirement applications) are all available.
Yes. You can contact us to select samples, specifying the quantity and requirements.
Yes. Particle size, column diameter, honeycomb size, pore size, and iodine value/CTC can all be customized to your needs.
