\n\n\n\nRaw Materials for Coal-Based Activated Carbon<\/h2>\n\n\n\n
The primary raw materials are bituminous coal, anthracite coal, and lignite<\/strong>. These materials are chosen based on their carbon content, ash level, and volatile matter. Pre-treatment steps include:<\/p>\n\n\n\n\n- Crushing to uniform particle size<\/li>\n\n\n\n
- Screening to remove impurities<\/li>\n\n\n\n
- Drying to reduce moisture content<\/li>\n<\/ul>\n\n\n\n
Proper raw material selection ensures high-quality activated carbon with optimal adsorption and mechanical strength.<\/p>\n\n\n\n
\n\n\n\nWorking Principle of Coal-Based Activated Carbon Rotary Kiln<\/h2>\n\n\n\nStep 1: Feeding and Preheating<\/h3>\n\n\n\n
Crushed coal is fed into the rotary kiln. Preheating ensures uniform temperature distribution and prepares the coal for carbonization.<\/p>\n\n\n\n
Step 2: Carbonization<\/h3>\n\n\n\n
Inside the kiln, the coal is heated in an oxygen-limited environment. Volatile compounds are removed, leaving carbon-rich char. The rotary motion ensures even exposure to heat, improving carbon yield and reducing defects.<\/p>\n\n\n\n
Step 3: Activation<\/h3>\n\n\n\n\n- Steam Activation<\/strong>: High-temperature steam reacts with carbon, forming micropores.<\/li>\n\n\n\n
- Activation chimique<\/strong>: Chemical agents like KOH or H\u2083PO\u2084 are used for higher surface area.<\/li>\n<\/ul>\n\n\n\n
Step 4: Cooling and Screening<\/h3>\n\n\n\n
Activated carbon is cooled to prevent oxidation, then screened to achieve uniform granule size. Optional crushing and granulation can produce pellets or powder.<\/p>\n\n\n\n
Step 5: Packaging<\/h3>\n\n\n\n
The final product is packaged for storage or shipment.<\/p>\n\n\n\n
