Pyrolysis - Wikipedia

Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It involves a change of chemical composition.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. In general, pyrolysis of organic .
