The chemical production of activated carbon is a process of carbonizing and activating raw materials through chemical reactions. This method usually uses strong oxidizing chemical reagents, such as phosphoric acid, zinc chloride, sodium hydroxide, etc., to react with raw materials (such as coconut shells, wood, coal, etc.) to achieve the purpose of increasing the specific surface area and pore structure of carbon materials. Activated carbon produced by chemical methods has a higher specific surface area and better adsorption capacity, and is widely used in air purification, sewage treatment, food and beverage, medicine, and environmental protection.

Equipment for producing activated carbon by chemical methods usually includes the following key parts:

Chemical reactor: This is the core equipment in the chemical production process. The reactor is used to mix the raw materials with the chemical activator and react at a certain temperature and pressure to form the initial structure of the activated carbon.

Carbonization furnace: The raw materials that have undergone chemical reactions need to be treated at high temperature in the carbonization furnace, usually at a temperature of 400-800℃, to remove volatile substances and complete the carbonization process.

Activation furnace: The activation furnace is used to further enhance the pore structure of the activated carbon. By adding steam or other gases to the carbonized raw materials, physical changes are made to form a microporous structure and enhance the adsorption capacity.

Cooling equipment: The carbon material after carbonization and activation needs to be cooled to room temperature to avoid excessive temperature causing changes in the characteristics of the activated carbon. The cooling equipment usually uses water cooling or air cooling.

Grading and screening system: After the activated carbon is cooled, it needs to be graded by screening equipment to ensure that activated carbon of different particle sizes is obtained to meet the needs of different applications.

Packaging system: The graded activated carbon finally needs to be packaged for easy storage and transportation.

The advantage of the chemical method for producing activated carbon equipment is that its process is simple and can produce activated carbon with excellent adsorption performance, which is suitable for mass production. A lot of chemical reagents and energy will be consumed during the reaction process.
