CARBON ACTIVATION PLANT
AGICO offers EPC projects for fully automatic carbon activation plants with a daily output of 2.6-8 tons. The customization service is available so that we can meet any production needs.
What is carbon activation? Carbon activation is a crucial link in the activated carbon production process, which is located after biomass carbonization. The purpose of carbon activation is to use steam or chemical substances to remove the tar substances and cracking products accumulated in the pore structure during the carbonization process so as to improve the surface area of the pores and the adsorption capacity. The carbon after activation treatment is so-called activated carbon, which has super adsorption capacity and is widely used in our daily life and industrial production.
AGICO is professional and experienced in offering activated carbon making machines and activated carbon plants. We mainly adopt activated carbon rotary kiln and physical activation process to realize carbon activation. Physical activation usually refers to gas activation. It uses water vapor, carbon dioxide, or air as the activating gas, and selectively oxidizes the carbonized material at a high temperature of 800-1000 °C so that the original pores in the material are further enlarged, new pores are generated, and the tar and other substances are removed.

Carbon Activation Process
Preheating Stage (800℃):
The activation rotary kiln will be firstly preheated by a burner. Then the carbonized material is fed into the feed bin by a bucket elevator and enters the activation rotary kiln through the frequency conversion feeder. With the rotation of the kiln body, the material gradually enters the preheating stage and the temperature rises to about 800 °C.
Activation Stage (900-1050℃):
The draught fan feeds an appropriate amount of oxygen into the kiln, and then the steam is turned on. The steam is penetrating steam, and 4 tons of steam is required to produce 1 ton of activated carbon. After the carbonized material reacts with steam and oxygen, the temperature rises rapidly to 900-1050°C. The time when the material is in contact with steam is called activation time. According to different temperatures and oxygen supply, the activation time is about 30-40 minutes, that is, the material moves forward with the rotating kiln body at a speed of 6 meters per hour. At this stage, the original pores in the material are further enlarged, new pores are generated, and the tar and other substances are removed.
Cooling Stage (30-40℃):
After activation, the activated carbon enters the discharge pipe at the end of the kiln and gradually cools down to 200 ℃. Then it automatically slides down to a water cooling device outside the kiln. After a 3-minute anaerobic cooling, the temperature of the activated carbon drops to 30-40°C.
Waste Gas Treatment Stage:
A combustion chamber is equipped at the end of the kiln. Behind the combustion chamber is a waste heat boiler. The high-temperature exhaust gas (about 800℃) drives the waste heat boiler to generate steam, which is used to activate the carbonized material. After that, the exhaust gas enters the exhaust gas treatment equipment such as the bag filter and spray tower for purification.
