Product Description
Advantages
1. 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.
2. 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.
3. 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.
4. 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.
Product Parameters
Applications
1.Gold Smelting
The core application of coconut shell gold-adsorbing activated carbon centers on precious metal extraction, playing an irreplaceable role-particularly within the gold smelting industry.
2. 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.
3. 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.
4. 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.
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.
6. 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.
