Instruction

Carbon activation plant is continuous production equipment used to produce high-quality activated carbon from carbon raw materials by means of physical activation. Carbon activation plants can be used in the activation process of biomass carbonization materials, charcoal, and coal-based carbon. The carbonized material is obtained by the carbonization plant, and the raw materials of the biomass carbonized material are various, including but not limited to coconut shell, apricot shell, palm shell, nut shell, fruit shell, sawdust, rice husk, straw, etc.

The main equipment of the activation production line is the carbon activation kiln. The final product activated carbon produced by the continuous activation kiln produced by Hengyang Industry has high quality and can be widely used in water purification and other fields.

After the initial porous structure has been created by carbonization, an oxidation, referred to as activation, is carried out in order to create micropores. Typically, these micropores have a width of less than 2 nanometers and are the pores where the majority of adsorption occurs. Activation can be carried out as activation by oxidizing gases or a chemical activation.

In activation by oxidizing gases, such as steam activation, carbon reacts with the oxidizing agent producing oxides of carbon. These oxides diffuse out of the carbon resulting in a partial gasification which opens pores that were previous closed and further develops the carbons internal porous structure.

In chemical activation, the carbon is reacted at high temperatures with a dehydrating agent that eliminates the majority of hydrogen and oxygen from the carbon structure. Chemical activation often combines the carbonization and activation step, but these two steps may still occur separately depending on the process. High surface areas in excess of 3,000 m2/g have been found when using KOH as a chemical activating agent.

A significant amount of carbon mass loss occurs during the activation which generally correlates to an increase in porosity. Therefore, quick estimates of porosity can be made by a gravimetric measurement. These gravimetric measurements can be used to compare carbons made using different process parameters and raw materials.
