Coal based Activated Carbon: 

Activated carbon, also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. Activated carbon is carbon produced from carbonaceous source materials like nut shells, peat, wood, coir, lignite, coal and petroleum pitch. It can be produced by one of the following processes:

1.Physical reactivation:

The precursor is developed into activated carbons using gases. This is generally done by using one or a combination of the following processes: Carbonization: Material with carbon content is pyrolyzed at temperatures in the range 600-900 °C, in absence of oxygen (usually in inert atmosphere with gases like argon or nitrogen) Activation/Oxidation: Raw material or carbonized material is exposed to oxidizing atmospheres (carbon monoxide, oxygen, or steam) at temperatures above 250 °C, usually in the temperature range of 600–1200 °C.

2.Chemical activation:

Prior to carbonization, the raw material is impregnated with certain chemicals. The chemical is typically an acid, strong base, or a salt. Then, the raw material is carbonized at lower temperatures (450–900 °C). It is believed that the carbonization / activation step proceeds simultaneously with the chemical activation. Chemical activation is preferred over physical activation owing to the lower temperatures and shorter time needed for activating material.
