Activated carbon is a kind of specially treated carbon. It heats organic raw materials (husk, coal, wood, etc.) in the air to reduce non-carbon components (this process is called carbonization), and then reacts with the gas, and the surface is Erosion produces microporous structures (this process is called activation).

Nutshell activated carbon is an activated carbon. It is black granular and used for purification of industrial harmful gases such as selenium carbon disulfide, vinyl chloride, methanol, acetone and nitrogen oxide.

Coconut shell activated carbon, using high-quality coconut shell as raw material, is refined through a series of production processes. The appearance of coconut shell activated carbon is black and granular.

Coal activated carbon is developed through a series of processes such as carbonization → cooling → activation → washing. Its appearance is generally black cylindrical activated carbon, irregular shaped coal granular activated carbon, also known as broken carbon.

Powdered activated carbon is made from high-quality wood chips and coal, and is processed through a series of production processes.

Cylindrical activated carbon is grayish black in appearance, cylindrical in shape, odorless and non-toxic.
