Pyrolysis | chemical reaction | Britannica

Pyrolysis, the chemical decomposition of organic (carbon-based) materials through the application of heat.Pyrolysis, which is also the first step in gasification and combustion, occurs in the absence or near absence of oxygen, and it is thus distinct from combustion (burning), which can take place only if sufficient oxygen is present. The rate of pyrolysis increases with temperature.
