As an efficient adsorption material, the industrial production process of activated carbon integrates the wisdom of material science and thermochemical processes. As a professional equipment supplier in the field of carbonization technology, we deeply analyze the whole process of activated carbon production and provide professional solutions for industry users.
1. Raw material preparation:The raw material screening adopts particle size classification technology, and through a multi-stage vibration screening system, the raw materials such as wood and coconut shells are accurately controlled within the particle size range of 2-5mm. The pretreatment workshop is equipped with a nitrogen protection crushing system to effectively prevent the oxidation loss of organic components. Raw material pretreatment directly affects the carbonization activation efficiency. Our equipment can increase the raw material utilization rate by more than 15%.
2. Carbonization:The carbonization section adopts a three-temperature zone rotary kiln design to realize a gradient temperature control process: the low temperature zone (200-300℃) completes dehydration and degreasing, the medium temperature zone (400-600℃) performs pyrolysis reaction, and the high temperature zone (800-1000℃) forms a stable carbon skeleton. By precisely controlling the heating rate (5-10℃/min) and residence time (30-120min), the carbonization yield can reach 25-35% of the raw material quality.
3. Activation:The physical activation system integrates a high-temperature steam generator to achieve a 200% increase in micropore expansion rate at 850-950℃. The chemical activation unit adopts a KOH cyclic impregnation process, and the activator recovery rate reaches more than 85%. The composite activation technology developed by our company can make the BET specific surface area exceed 2000m²/g, and the iodine adsorption value reaches more than 1100mg/g.
4. Post-processing process optimization:The ultrasonic countercurrent washing system can remove 99% of the activator residues, and the three-stage centrifugal dehydration equipment reduces the moisture content to less than 5%. The microwave drying system saves 40% energy compared to traditional hot air drying, and the particle size sorting accuracy can reach ±0.1mm. The intelligent packaging line integrates metal detection and vacuum nitrogen filling functions to ensure stable product quality.
