Coconut shell activated carbon is a high-end adsorption material made from high-quality coconut shells from Southeast Asia through screening, carbonization, high-temperature activation, and precise post-processing. It appears as black, irregular granules (or broken pieces), with a hard texture and an extremely well-developed pore structure. Its specific surface area can reach 1000-1500 m²/g, and its iodine adsorption value is ≥900 mg/g. It possesses core advantages such as large adsorption capacity, fast adsorption rate, strong selectivity, non-toxicity, odorlessness, and easy regeneration. Its natural raw material properties and excellent adsorption performance make it a preferred material for drinking water purification, high-end decolorization, and gas phase deodorization, combining environmental friendliness with high cost-effectiveness.

Coconut Shell Activated Carbon Product Details:

I. Core Raw Materials and Production Process

Raw Material Advantages: Selected high-quality coconut shells imported from Malaysia and Indonesia, with a dense fiber structure, high carbon content (≥92%), and extremely low ash content (≤3%), ensuring the product’s adsorption performance and purity from the source, eliminating the risk of secondary pollution.

Refining Process: The process involves multiple steps including raw material screening (removing impurities and sorting high-quality coconut shells) → high-temperature carbonization (500-700℃, decomposing volatile substances) → activation treatment (850-950℃ steam activation to build well-developed pores) → crushing and grading (processing into specifications such as 8-20 mesh and 20-40 mesh according to requirements) → acid washing to remove impurities (reducing ash and metal ion content) → drying and packaging. No harmful chemical agents are added throughout the entire process, and the product meets food-grade and drinking water-grade standards.

II. Key Performance Indicators

Adsorption Performance: Iodine adsorption value 900-1200 mg/g, methylene blue adsorption value 150-200 mg/g, specific surface area 1000-1500 m²/g, total pore volume ≥1.0 cm³/g, carbon tetrachloride adsorption rate ≥60%. Basic Properties: Moisture ≤5%, Ash ≤3%, Fixed Carbon ≥92%, pH 6.5-8.5, Mechanical Strength ≥95% (not easily broken or pulverized), Packing Density 0.45-0.55 g/cm³.

Safety Standards: Complies with the “Standards for the Use of Drinking Water” and the “Standards for the Use of Food Additives,” heavy metal (lead, arsenic, mercury, etc.) content ≤0.001%, odorless and non-corrosive.

III. Core Product Advantages

Superior Pore Structure: Primarily microporous (pore size ≤2nm), combined with an appropriate amount of mesopores, precisely targeting small molecule harmful substances (such as chlorine, heavy metals, odor molecules), resulting in more targeted adsorption.

Top-Tier Adsorption Efficiency: The ultra-large specific surface area provides superior adsorption capacity, with adsorption rates for residual chlorine, organic matter, and color in water, and formaldehyde and benzene compounds in the air exceeding 30% faster than ordinary coal-based activated carbon, and a longer saturation period.

Natural, Safe, and Environmentally Friendly: Made from pure coconut shells, with no chemical additives, leaving minimal residue after activation. It causes no secondary pollution in drinking water and food processing applications, and is biodegradable or recyclable after disposal.

High Durability: High mechanical strength, wear-resistant, and impact-resistant. It does not easily pulverize under conditions of water flow and air turbulence. After regeneration, its adsorption performance retains ≥85%, and its service life can reach 3-5 years.

IV. Main Application Areas

Drinking Water Purification: Used in household water purifiers, bottled water production, and deep treatment in waterworks. It efficiently removes residual chlorine, odors (such as bleach or musty smells), heavy metals (lead, mercury, cadmium), and organic matter (chloroform, pesticide residues), improving water quality and safety.

Food and Beverage Processing: Used for decolorizing and removing impurities and odors from alcoholic beverages (baijiu, beer, wine); decolorizing and purifying fruit juices, syrups, and vinegar while preserving the original flavor and nutrients.

Gas-phase purification: Indoor air purification (removal of formaldehyde, benzene, TVOC, and other pollutants from renovations), refrigerator/shoe cabinet deodorization, car interior odor removal; industrial waste gas treatment (VOCs adsorption in the chemical and electronics industries, odor purification in paint booths).

Wastewater treatment: Deep treatment of high-end industrial wastewater (electroplating, dyeing, pharmaceuticals), adsorption of heavy metal ions and recalcitrant organic matter; purification and deodorization of swimming pool water and landscape water features.

Other applications: Gold extraction (adsorption of gold cyanide complexes), catalyst carriers, medical protective materials (gas mask filter media), tobacco filter fillers, etc.

V. Specifications and Usage Recommendations

Specifications: 8-20 mesh particles are recommended for drinking water purification (compatible with water purifier filter cartridges); 20-40 mesh particles are recommended for food decolorization and waste gas treatment; 40-60 mesh particles are recommended for fine chemical catalysis.

• Usage recommendations: When using liquid phase adsorption, the water flow rate should be controlled to ≤10m/h to avoid insufficient adsorption; when using gas phase adsorption, ensure that the contact time between the gas and activated carbon is ≥0.5 seconds; replace or regenerate regularly (regeneration temperature 800-900℃) to avoid secondary release of pollutants after adsorption saturation.
