Activated carbon

Activated carbon is a special treatment of carbon, the organic raw materials (nut shell, coal, wood, etc.) in the isolation of air under the condition of heating, in order to reduce the non-carbon components (this process is called carbonization), and then react with gas, the surface is eroded, produce microporous developed structure (this process is called activation). Because the activation process is a microscopic process, that is, a large number of molecular carbide surface erosion is point erosion, resulting in the activated carbon surface has numerous small pores. Most of the micropore diameter on the surface of activated carbon is between 2 ~ 50nm. Even a small amount of activated carbon has a huge surface area of 500~1500m2 per gram of activated carbon. Almost all the applications of activated carbon are based on this characteristic of activated carbon.
