Coconut Shell Activated Carbon for Industrial Filtration

Product Description

Product Description

Coconut shell granular activated carbon is produced from high-quality coconut shells. After crushing, the resulting granules feature an irregular shape, high mechanical strength, and high saturation capacity, while also being a renewable resource.

Visually, this activated carbon appears black and granular; it possesses a highly developed pore structure and offers excellent adsorption performance, high durability, and cost-effectiveness.
 

Advantages

1. High Specific Surface Area:
Reaching 1,000-1,500 m²/g-meaning the unfolded surface area of just one gram of activated carbon is nearly equivalent to one and a half badminton courts-which significantly enhances adsorption efficiency.

2. Strong Adsorption Performance:
The iodine value typically ranges between 900 and 1,250 mg/g, with some high-quality products exceeding 1,100 mg/g; this demonstrates its exceptional adsorption capacity for substances in both gaseous and liquid phases.

3. Excellent Mechanical Strength:
With a mechanical strength of ≥95%, it resists crushing and pulverization during use, making it ideally suited for continuous operation systems utilizing fixed beds or fluidized beds.

4. Eco-friendly and Renewable:
Sourced from renewable coconut shell resources, it aligns with the principles of sustainable development; furthermore, once saturated, it can be regenerated via high-temperature treatment and reused.

Applications

1. Drinking Water and Water Purification
Granular coconut shell activated carbon serves as a critical material in advanced water purification processes. It efficiently removes residual, odors, organic matter, pesticide residues, and certain heavy metal ions from water, thereby significantly enhancing both water safety and taste.

2. Indoor and Automotive Air Purification
Targeting harmful gases-such as formaldehyde, benzene, and TVOCs-released following interior renovations, granular coconut shell activated carbon achieves effective removal through passive adsorption. It serves as a core component in air purifiers, fresh air ventilation systems, and formaldehyde-removal packets.

3. Food and Refining
In the production of beverages, alcoholic spirits, MSG, citric acid, and similar products, granular coconut shell activated carbon is utilized for the decolorization, deodorization, and impurity removal of mother liquors, thereby ensuring the purity of product color and food safety.

4. Gold Extraction and Metallurgy
In gold extraction processes utilized by over 70% of the world's gold mines, granular coconut shell activated carbon acts as the primary adsorbent in both the "Carbon-in-Pulp" (CIP) and "Heap Leaching" methods, enabling the efficient recovery of gold-cyanide complexes from solution.

5. Industrial Waste Gas Treatment and Solvent Recovery
In industries such as chemical manufacturing, printing, and surface coating, granular coconut shell activated carbon is employed to adsorb volatile organic compounds (VOCs)-including benzenes, ketones, and esters-and can be integrated with steam desorption systems to facilitate the regeneration and reuse of solvents.
