Coconut shell activated carbon is a type of activated carbon made from coconut shells. Its high surface area and rich pore structure give it excellent adsorption, separation, and catalytic properties, making it widely used in air purification, water treatment, the food industry, the pharmaceutical industry, and the chemical industry.

Main Components of a Coconut Shell Activated Carbon Production Line:

Raw Material Pretreatment: The raw material is first crushed and screened to a size of 1-3 cm. It then enters a drum dryer, utilizing waste heat from the production line to control the moisture content to 8-15%. The dryer exhaust undergoes dust removal and fume scrubbing to meet emission standards.
Carbonization: The coconut shells are carbonized using indirect heating at a temperature of 650-850°C. The carbonization furnace’s drum is constructed of high-temperature-resistant stainless steel, is fully enclosed, and operates at a slight negative pressure. The combustible gas generated during the carbonization process serves as fuel, providing heat for the carbonization process, eliminating the need for additional fuel. The carbonized coconut shell charcoal can be activated directly or cooled as a finished product for further processing.

Activation: Coconut shell charcoal is activated using direct heating at a temperature of 850-950°C for 60-120 minutes. The drum of the activation furnace is lined with carbon steel and refractory materials. The furnace is fully enclosed and operates at a slight negative pressure. Natural gas/oil fuel is used. Temperature, residence time, steam dosage, and oxygen supplementation can all be precisely controlled, enabling the production of coconut shell activated carbon to various specifications.
Cooling: Indirect water cooling is employed, using a water-cooled screw conveyor and drum cooler.
Waste gas treatment: Exhaust gases generated during the carbonization and activation processes are treated. These processes include secondary combustion, waste heat steam generation, waste heat recovery, temperature control, pulse dust removal, and wet deacidification. These processes remove harmful substances from the exhaust gas while maximizing waste heat utilization.
Product processing: The activated carbon undergoes crushing, grinding, screening, and packaging.
