Extruded Activated Carbon

extruded activated carbon Activated carbon, is a specially treated carbon that heats organic raw materials (rice husks, coal, wood, etc.) in the absence of air to reduce non-carbon components (this process is called carbonization), and then Reacting with the gas, the surface is corroded to produce a microporous structure (this process is called activation). Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, resulting in numerous small pores on the surface of activated carbon. The diameter of micropores on the surface of activated carbon is mostly between 2-50nm. Even a small amount of activated carbon has a huge surface area. The surface area per gram of activated carbon is 500-1500m2. Almost all applications of activated carbon are based on this characteristic of activated carbon.
