Guokr Activated Carbon Product Introduction: Guokr Activated Carbon is a porous adsorbent material produced from premium nut shells including walnut, apricot, and jujube shells. Through processes such as screening, low-temperature carbonization (500-700°C), high-temperature activation (800-1000°C), and purification, the shells are transformed into a material with a naturally dense wood-like structure. The specially processed shells develop a highly developed microporous system, offering advantages like high adsorption capacity, strength, and easy regeneration. Widely used in drinking water purification, food processing, and precious metal extraction, it stands as the optimal adsorbent material that balances cost-effectiveness and performance.

Appearance Characteristics: The product appears as irregular black granules, with slight variations in shape depending on the raw material. Walnut shell-based products have fuller granules, while apricot shell-based products have slightly sharper edges, with no obvious edges overall. Common particle sizes cover 6-12 mesh, 12-24 mesh, and 24-48 mesh, where 12-24 mesh is the general specification, and 24-48 mesh is suitable for fine purification scenarios. The surface of the granules is rough and porous, with a dry and non-greasy feel, and fine pores can be seen under strong light. The bulk density is 0.48-0.60g/cm³, between that of coconut shell activated carbon (0.42-0.50g/cm³) and coal-based activated carbon (0.55-0.75g/cm³). High-quality products have a particle integrity of ≥96%, with a wear rate of ≤2.5% after mechanical vibration testing. They maintain good initial buoyancy when soaked in water, and slowly settle after adsorption saturation, without significant pulverization.

Core Characteristics 1. Balanced Adsorption Performance: With a BET specific surface area of 900-1300 m²/g, the material features 75%-85% micropores (1-2 nm) and 10%-20% mesopores (2-50 nm), creating an optimal pore structure for adsorbing small molecular pollutants and select medium/large molecules. Key performance metrics demonstrate exceptional results: iodine adsorption capacity of 850-1100 mg/g, methylene blue adsorption of 120-180 mg/g, and phenol adsorption ≥35 mg/g. In drinking water purification, it achieves over 99.5% residual chlorine removal efficiency, with organic adsorption rates 20%-30% higher than coal-based activated carbon.

Robust Mechanical Strength: With a mechanical strength of ≥94% (reaching 96% for walnut shell-based products), it withstands dynamic conditions like water treatment backwashing and fluidized bed adsorption. During backwashing in water treatment plants (10-15L/(m²·s) intensity), the breakage rate remains below 1%, minimizing carbon powder's impact on effluent quality. Its exceptional wear resistance ensures low carbon consumption during prolonged use, significantly reducing operational costs.

Chemically stable: The product maintains a pH range of 6.0-9.0, neutral in nature, without altering the acidity or alkalinity of the treatment medium. With sulfur content ≤0.2% and nitrogen content ≤1.0%, it exhibits strong chemical inertness, showing no reaction with common organic compounds or heavy metal ions in water. The food-grade product strictly complies with GB/T 12496-2015 standards, featuring ultra-low heavy metal levels (arsenic ≤5mg/kg, lead ≤20mg/kg, mercury ≤0.1mg/kg), meeting all food safety requirements.

Excellent regenerability: Utilizing high-temperature steam regeneration (350-450°C), the adsorption capacity can recover to 80%-85% of its initial value. The regeneration cycle is one-third of the adsorption cycle, allowing 5-8 regeneration cycles. Compared to coconut shell activated carbon, this method reduces energy consumption by 15%-20%, offering superior overall operational costs, making it particularly suitable for large-scale continuous systems.

III. Application Fields 1. Drinking Water Purification: In advanced treatment systems for water treatment plants, 12-24 mesh fruit shell activated carbon-filled filters effectively remove residual chlorine, odors, halogenated hydrocarbons, and trace pesticide residues. The treated water contains ≤0.05mg/L of residual chlorine and has odor levels below the 20 odor threshold units, meeting the GB 5749-2022 Drinking Water Hygiene Standard. For household water purifiers, 24-48 mesh fine-grained carbon serves as the core filter material, with a single cartridge capable of processing 2-5m³ of water, ensuring safe drinking water for families.

Food and Beverage Industry: In the sugar industry, this process is used for decolorization and purification of sucrose and fructose syrup. A dosage of 0.2%-0.4% effectively removes caramel pigments and melanoidin from sugar solutions, elevating product whiteness to over 92%. In alcoholic beverage production, it clarifies yellow rice wine and fruit wines by adsorbing aldehydes and ester impurities, resulting in a purer taste and extending shelf life by 6-12 months. In the beverage sector, it neutralizes astringency in fruit juices and removes impurities from tea beverages, eliminating tannic acid and bitter compounds while preserving original flavors and nutritional components.

Precious Metals Extraction: In heap leaching and carbon slurry extraction processes for gold, silver and other precious metals, 6-12 mesh fruit shell activated carbon demonstrates high efficiency in adsorbing gold cyanide complexes and silver cyanide complexes from cyanide leaching solutions. The adsorption capacities reach 350-500g/t for gold and 800-1200g/t for silver, with a desorption efficiency of ≥97%. This technology is particularly suitable for extracting medium-to-low grade gold and silver ores, and has been widely adopted in mining regions such as Henan and Shandong.

Industrial Wastewater Treatment: In chemical wastewater treatment, it effectively removes organic pollutants such as benzene, toluene, and phenols, achieving a COD removal rate of 35%-55%. For dyeing wastewater, it decolorizes reactive and acid dyes with 80%-90% efficiency. In electroplating wastewater treatment, it adsorbs and removes heavy metal ions (e.g., chromium, nickel, copper) at over 90%, serving as a key advanced treatment unit to ensure compliance with discharge standards.

Gas-phase purification applications: In industrial exhaust treatment, it effectively adsorbs VOCs emitted by coating and printing industries, achieving 80%-90% efficiency for benzene and ethyl acetate. As a core material in activated carbon packs and air purifier filters, it removes 70-120mg/g of formaldehyde and TVOCs, significantly improving indoor air quality. Additionally, it serves as a filter cartridge in gas masks to neutralize toxic gases, ensuring worker safety.

Packaging Specifications The product features a double-layer moisture-proof packaging system. The inner layer consists of 0.10mm-thick food-grade polyethylene (PE) film bags with superior moisture resistance, preventing powder from absorbing moisture and clumping. The outer layer is made of 80-100g/m² high-strength polypropylene woven bags or imported kraft paper bags, with a tear strength of ≥25N, capable of withstanding external impacts during handling and transportation.

Standard packaging specifications: Small-batch trial packs are available in 1kg/5kg bags with sealed zippers for easy refilling, while standard industrial packaging comes in 25kg/50cm×80cm bags featuring reinforced handles for manual handling. Bulk purchases can be provided in 500kg/ton bags (granular charcoal) with containerized packaging and lifting rings for forklift loading. All packaging clearly displays product name, model, particle size, iodine adsorption value, production date, batch number, and quality grade. Food-grade and industrial-grade products are distinguished by color labels (food-grade with green bands, industrial-grade with gray bands) to prevent confusion. Store in a cool, dry place when sealed. The shelf life is 2 years, and opened products must be resealed and used within 30 days.

Precautions 1. Storage Guidelines: Store in a dedicated dry warehouse maintained at 5-35°C with relative humidity ≤60%, avoiding direct sunlight and proximity to high-temperature sources (e.g., steam pipes, heating furnaces). The warehouse must be equipped with moisture-proof ventilation systems. Place products on wooden or plastic pallets at least 10cm above the floor/walls to prevent moisture ingress. Strictly prohibit mixing with strong acids, strong alkalis, toxic gases, or volatile chemicals. Maintain a minimum 5-meter separation between all materials to prevent cross-contamination that may impair product adsorption performance.

Transportation Requirements: Transport vehicles must be kept dry and clean, with rainproof fabric and moisture-proof padding installed in the cargo compartment. Handling procedures must be performed gently, and the use of sharp tools like iron hooks to drag packages is strictly prohibited to prevent packaging damage and particle leakage. During transit, measures must be taken to protect against rain, sunlight, and dust, and the vehicles must not be loaded with hard materials such as stones or steel, nor mixed with liquid cargo. For long-distance transportation, the packaging integrity must be regularly inspected, and any damage found must be promptly sealed. The transport vehicles must also be equipped with appropriate fire prevention facilities.

Operating Procedures: Before loading the adsorption equipment, rinse the surface 1-2 times with clean water to remove dust. Collect and treat the rinse wastewater to prevent environmental contamination. In the water treatment system, the activated carbon filter layer should be 1.5-2.0 meters high, with a filtration rate maintained at 8-12 m/h to ensure effective treatment. Regularly monitor pollutant concentrations in both influent and effluent (gas) during operation. When the adsorption efficiency drops below 50% of the initial value, regeneration or replacement is required. The regeneration process uses high-temperature steam desorption, lasting 8-10 hours.

Safety Warning: The product has a flammability range of 450-500°C and is classified as non-flammable. However, in enclosed spaces with poor ventilation where large quantities are stored, trace heat released during adsorption may accumulate. Therefore, open flames must be strictly prohibited in storage and usage areas. Fire-fighting equipment such as dry powder fire extinguishers must be provided, and fire safety equipment should be inspected monthly to ensure effectiveness. Operators must wear dust masks, protective goggles, and latex gloves during loading to prevent particle inhalation and skin contact. Spent adsorption saturated carbon must be disposed of by professional environmental agencies and must not be dumped indiscriminately to avoid secondary pollution.
