Coconut Shell Activated Carbon Product Introduction: This high-performance porous adsorbent is produced from premium Southeast Asian coconut shells through a three-step process: high-temperature carbonization , steam activation , and precision refining. With a carbon content exceeding 75% and modular manufacturing technology, it finds extensive applications in water treatment, precious metal extraction, and other industrial sectors.
Appearance Characteristics: The product appears as black irregular granules, with full and smooth granules that reduce equipment wear. The particle size ranges from 4-8 mesh (for precious metal extraction), 6-12 mesh (for industrial wastewater), to 20-50 mesh (for drinking water), and can also be customized to 1-8mm. Its bulk density is 0.45-0.55g/cm³, lower than that of coal-based activated carbon; it has good initial floatation in water, with bubbles forming during adsorption and settling at the bottom when saturated. High-quality products have a clean surface, with a pulverization rate below 3%, meeting the requirements for continuous operation.
Core Characteristics 1. Excellent adsorption performance: BET specific surface area of 950-1500 m²/g, with over 85% micropores (pore size 1-2 nm), iodine adsorption value of 900-1250 mg/g, and methylene blue adsorption value of 135-210 mg/g. The adsorption rate and capacity are 30% and 25%-40% higher than coal-based activated carbon, respectively. 2. Strong physical stability: Mechanical strength ≥95% (99% for water purification-specific types), resistant to wear and impact, less prone to breakage during dynamic operation, reducing carbon powder loss. 3. Stable chemical properties: Sulfur content <0.1%,pH6.5-11; food-grade products comply with GB/T 12496-2015, heavy metals (arsenic ≤10 ppb, lead ≤200 ppb) meet standards, and performance recovery rate after high-temperature regeneration exceeds 85%.
Application Fields 1. Water Treatment: For drinking water purification, it removes chlorine (removal rate 99%-100%), heavy metals, and odors, complying with GB 5749-2022 standards. In industrial wastewater treatment, it reduces COD and decolorizes, lowering the color intensity of coking wastewater from 130 times to below 8 times. 2. Precious Metal Extraction: Enriches gold elements in gold heap leaching/carbon slurry methods, with an adsorption capacity of 300-500g/t and desorption efficiency exceeding 95%, making it a mainstream material in mineral processing. 3. Food & Pharmaceutical: Used for impurity removal in alcoholic beverages, flavor enhancer decolorization, and citric acid refining. Pharmaceutical-grade products can purify drug intermediates, meeting medical standards. 4. Gas Purification: As a core material in anti-toxicity equipment and air purifiers, it adsorbs formaldehyde and benzene with efficiency over 90%, adopted by brands like Bruyart. 5. Industrial Auxiliary: Recovers solvents like gasoline and acetone (efficiency>90%); serves as a vinylidene chloride catalyst carrier to reduce energy consumption and improve efficiency.
IV. Packaging Specifications The product features a double-layer sealed packaging system: an inner 0.08mm food-grade PE film for moisture resistance, and an outer 80g/㎡ high-strength woven bag for tear resistance. Standard size: 25kg/bag (50cm×80cm). For bulk orders, 500kg/ton (100cm×120cm) or 500kg/ pallet packaging is available. Packaging labels include model, iodine value, particle size, and other specifications, with food-grade (green label) and industrial-grade (gray label) products stored separately. The product has a 2-year shelf life when sealed, and is recommended to be used within 30 days after opening.
Precautions 1. Storage: Store in a warehouse at 5-35°C with humidity <60%, packaging at least 10cm above ground. Maintain at least 5 meters from toxic gases and volatile substances to prevent premature adsorption failure. 2. Transportation: Handle with care during loading/unloading; avoid iron hook dragging. Protect from rain and sunlight, avoid mixing with hard objects. Inspect packaging integrity during long-distance transport. 3. Usage: Strictly prevent water immersion and moisture exposure. Test adsorption efficiency every 3-6 months for drinking water systems, and every 1-2 months for industrial wastewater systems. Regeneration (300-400°C steam purging) or replacement required if efficiency drops below 50% of initial value. 4. Safety: Keep away from open flames and high-temperature sources (≥10m distance). In enclosed spaces, ventilate for 30 minutes every 2 hours. Operators must wear dust masks.
