How to Make Activated Carbon？

The making process of activated carbon mainly includes three steps: raw material selection, carbonization, and activation.

Raw material selection:

The raw materials of activated carbon can be coal, wood, coconut shells, walnut shells, apricot shells, jujube shells and other carbon-rich organic materials. After these raw materials are crushed, screened, and dried for pretreatment, they enter the next step of carbonization.

Carbonization: 

During the carbonization stage, the raw materials are heated in an oxygen-deficient environment at a temperature generally between 600 and 900°C. During this process, the water in the raw materials evaporates to form a preliminary carbonized product.

Activation: 

Activation is a key step in the manufacture of activated carbon. It mainly activates the surface of the carbonized product by introducing gas (such as water vapor, carbon dioxide, etc.) to improve its adsorption performance. During the activation process, the gas reacts chemically with the carbonized product to generate more porous structures, thereby increasing the specific surface area of the activated carbon. After activation, the activated carbon is made.
The most important machine used in the activation process is the activation carbon furnace. The activation carbon furnace produced by Henan Hengju Machinery is different from the slep furnace used in the past. The slep furnace is a vertical furnace that cannot produce continuously and needs to be cast on site with refractory bricks and refractory mud. The activation carbon furnace is shipped as a complete machine and can be put into use with simple on-site installation. The equipment can continuously produce activated carbon with high output, easy use and low labor cost.
