What is activated carbon?
Activated carbon is a carbon-based material that has been processed to maximize its adsorptive properties, yielding a superior adsorbent Material.
Activated carbon boasts an impressive pore structure that causes it to have a very high surface area on which to capture and hold materials, and can be produced from a number of carbon-rich organic materials, including:
- Coal
- Coconut Shell
- Wood
- Fruit Shell
Properties of activated carbon
When selecting an activated carbon for a particular application, a variety of characteristics should be considered:
Activated carbon production
Activated carbon is produced through two main processes: carbonization and activation.
1. Carbonization
During carbonization, the raw material is thermally decomposed in an inert environment, at temperatures below 800 ºC. Through gasification, elements such as oxygen, hydrogen, nitrogen, and sulfur, are removed from the source material.
2. Activation
The carbonized material, or char, must now be activated to fully develop the pore structure. This is done through oxidizing the char at temperatures between 800-900 ºC in the presence of air, carbon dioxide, or steam.
Activated carbon applications
The ability to adsorb components from a liquid or gas lends itself to thousands of applications across a multitude of industries, so much so, in fact, that it would likely be easier to list applications in which activated carbon is not used. The primary uses for activated carbon are listed below.
Please note that this is not an exhaustive list, but merely highlights.
Coal activated carbon
Coal activated carbon process is carbonized → cooling → activation → washing and a series of processes. Its appearance is generally black. It has three shapes, granular activated carbon (broken carbon). Extruded activated carbon (pellet carbon), powder activated carbon. It has the characteristics of well-developed pore structure, good adsorption performance, and high mechanical strength.
