Carbonization refers to the process of converting organic matter into carbon. Some common synonyms of the word carbonizes include pyrolyzes, charcoals, combusts, incinerates, and burns. Pyrolysis is a form of carbonization that occurs when organic matter is heated in the absence of oxygen, resulting in the production of charcoal and other carbonaceous materials. Charcoal is a type of carbonized material that is commonly used for fuel and purification purposes. Combustion is a chemical process in which a fuel is burned, usually with the aid of oxygen, to produce heat and carbon dioxide. Incineration is the process of burning organic material to dispose of it.
