Pyrolysis - Wikipedia

Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It involves a change of chemical composition and is irreversible. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating".. Pyrolysis is most commonly used in the treatment of organic materials. It is one of the processes involved in charring wood.
