The Molecular Alchemy of Nature and Technology

1. Raw Material Traceability: The Renewable Mission of Tropical Coconut Shells Strictly Selected Origins: Mature coconut shells from Thailand, the Philippines, and Indonesia (shell thickness ≥ 3mm, carbon density > 0.6g/cm³) Zero Waste Recycling: Each ton of coconut shell charcoal consumes 5,000 discarded coconut shells, reducing the carbon footprint by 60%

2. Four-Stage Precision Activation Process ① Ultra-clean Cleaning: High-pressure spray + ultrasonic impurity removal (residue < 0.01%) ② Gradient Carbonization: 450-650°C temperature control in an oxygen-deficient environment, volatile matter removal > 95% ③ Steam Nano-Etching:

1050°C superheated steam (industry standard: 800-1000°C) Microporosity increased to ≥ 85% (pore size 0.8-2nm, precisely matched to Au(CN)₂⁻/VOC molecules)

④ Intelligent Screening: Laser particle size analyzer grading, 6×12 mesh particle uniformity deviation ≤±2%

Why is steam activation the preferred choice for industrial applications?

▶ Microporous Universe: An adsorption battlefield of 1500 m² per gram Specific Surface Area: 1100-1500 m²/g (Iodine Value ≥ 1100 mg/g) Gold Adsorption: Gold loading 350 g/ton of carbon (measured under CIP conditions) VOC Removal: Toluene adsorption capacity ≥ 400 mg/g (25°C)

▶ Diamond-grade structural strength Ball-disc hardness ≥ 98.5%: Withstands CIL tank impacts at 30 times per minute Pulverization rate < 0.8%: Extends life by over 3 times compared to chemically activated carbon, saving $120,000 in annual maintenance costs

▶ Absolute purity: Zero chemical residue Ash content ≤ 3%: Acid wash removes metal ions (Fe²⁺/Mn²⁺ < 10 ppm) NSF Certification: Complies with FDA/EC1935 food contact standards Core Industrial Applications 1. Cutting-edge water treatment Nuclear power plant primary circuit: Adsorption ⁶⁰Co/¹³⁷Cs, decontamination factor >1000 Chip factory ultrapure water: TOC control ≤1 ppb (18.2 MΩ·cm)

2. Gold Mining Revolution High-pressure adsorption tower: Withstands 10 MPa pressure, 99.8% desorption rate (measured at a mine in Ghana) Anti-poisoning formula: Saturated adsorption capacity of thiocyanate (SCN⁻) 120 mg/g

3. Aerospace-grade air purification Rocket fuel plant: 99.97% hydrazine vapor removal rate (NASA collaboration) Biosafety laboratory: HEPA + coconut shell carbon composite filter, intercepting 0.1μm aerosols Kelin Carbon’s pinnacle of technology Holographic quality control system Each batch includes a 3D pore scan report (Micro-CT imaging) Blockchain traceability: Scan the QR code to view the activation furnace temperature curve and raw material origin Global zero-time response

“At a high-arsenic gold mine in the Democratic Republic of the Congo, Kelin’s arsenic adsorption carbon (As capacity 45mg/g) reduced cyanide consumption by 40%, generating $2.7 million in annual efficiency gains. Their engineers even stayed on-site to optimize CIP tank flow patterns—they’re more than just a supplier, they’re a technical partner!” —Katanga CIL Project Director, mining giant
