The production process of activated charcoal exists in two forms. A source of carbon like coal, peat, or any organic carbonaceous material is carbonized. A heating method known as pyrolysis extracts the pure carbon from the source.

Once this process is complete, it is treated with oxygen, either by exposure to CO2 or steam or by an acid-based chemical treatment. The process is the chemical activation process.

Physical activation

The carbon source is heated at extremely high temperatures in the range of 600 to 900 degrees Celsius. Hot gases in an inert atmosphere like nitrogen or argon. It is again heated in an oxidizing atmosphere.
