Activated Carbon is the carbon produced by activation of any carbonaceous material such as coconut shells, bamboo, wood chips, sawdust, coal, lignite, paddy husk, etc. and is a highly porous, high-surface-area adsorptive material with a largely amorphous structure.
The base raw material has a significant impact on the final product properties, including pore size distribution and volume, hardness and purity. Most commercial activated carbons are manufactured from the following raw materials:
◘ Coconut shell
◘ Coal (anthracite, bituminous, sub-bituminous, lignite)
A Glance – Forms & Application
Activated carbon sorbents are tailored for specific applications mainly based on pore size and pore volume requirements. Porosity and other parameters are controlled by the following:
1) Raw material selection;
2) Activation process conditions
3) post-processing steps.
Depending on the application, activated carbon may be in the form of powder (PAC), granule (GAC) or Exturdate (EAC). All three forms are available in a range of particle sizes.
