Pyrolysis, the chemical decomposition of organic carbonbased materials through the application of heat. Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. Dxfcad templates carrier commercial systems north america. Because no oxygen is present the material does not combust but the chemical compounds i. In this treatment, material is exposed to high temperature, and in the absence of oxygen goes through chemical and physical separation into different molecules. 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.
