Defined as a form of carbon which is processed in order to riddle with low volume and small pores, Activated Carbon can be stated as a major example of product used for purification purposes. These are also known as activated charcoal and also carbon activates and help in increasing the surface area which is used for different chemical reactions or absorption purposes. In certain cases, the word activated can be seen substituted with active. One gram of this carbon product comprises of a surface area of 500 meter square due to the present of large rate of micro porosity.
The activated level can easily work well from high surface area even though specific chemicals are used in order to enhance the absorption properties. This product is generally derived from charcoal.
Production of Activated Carbon:
Activated carbon can be defined as a form of carbon which is produced from the carbonaceous materials such as coconut husk, wood, nutshells, peat, lignite, coir, petroleum pitch and more. These products can be processed by following these fields:

Production of Activated Carbon:
Activated carbon can be defined as a form of carbon which is produced from the carbonaceous materials such as coconut husk, wood, nutshells, peat, lignite, coir, petroleum pitch and more. These products can be processed by following these fields:
- Chemical activation: Before carbonization, raw materials are saturated with specific chemicals. This field is acid in nature along with a strong base and salt. After impregnation, this field is carbonized at lower temperatures as the process of carbonization works simultaneously with other chemical reactions as well.
- Physical activation: the main source material can be seen activated and developed into carbons with the help of different hot gases. This can take place with the help of few major chemical processes namely carbonization or activation and oxidation.
Classification of Activated Carbon:
- GAC or Granular Activated Carbon: The particle size is somewhat larger when compared with the powered carbons and also comprises of smaller external surfaces. Therefore, the diffusion purposes of absorbate rate are somewhat important in this regard. Thus, these carbons are generally preferred for absorption of different vapors and gases, as the rate is quite faster. These carbons are used for deodorization, water treatment, separation of components and also for fast mix basins.
- PAC and BAC: PACs available in powdered form and in granular forms as well which are 1.0 mm in size and the average diameter varies in between 0.15 mm and 0.25 mm. Also known as bead activated carbon, BAC is made out of petroleum pitch and the diameter ranges from 0.35 to 0.80 mm.
Activated Carbon Granules I have read all the comments and suggestions posted by the visitors for this article are very fine,We will wait for your next article so only.Thanks!
