Carbonization

Carbonization is a special form of pyrolysis. It describes the conversion of an organic source material into coal or a carbonaceous solid with the intention of obtaining as much solid material as possible. Carbonization is often used in the production of activated carbon from wood waste, hard coal, pitches, polymers and other raw materials. Activated carbon is a fine-grained carbon with a high internal surface area which is increasingly used as a filter due to its non-specific adsorption properties.
