Pyrolysis, often termed as dry distillation, is a transformative process involving the thermal decomposition of flammable organic substances. This operation occurs in the absence or with minimal oxygen presence. The outcome is the release of a mixture of flammable gases, with their composition and quantity influenced by several factors, such as the nature of the feedstock, temperature, residence time in the reactor, pressure, and heating rate. The output is fuel, gas, metal, carbon.
