Answer 2

Pyrolysis is a process of chemically decomposing organic materials at elevated temperatures in the absence of oxygen. The process typically occurs at temperatures above 430°C (800°F) and under pressure. It simultaneously involves the change of physical phase and chemical composition, and is an irreversible process. The word pyrolysis is coined from the Greek words "pyro" which means fire and "lysis" which means separating.

Pyrolysis is commonly used to convert organic materials into a solid residue containing ash and carbon, small quantities of liquid and gases. Extreme pyrolysis, on the other hand yields carbon as the residue and the process is called carbonization. Unlike other high-temperature processes like hydrolysis and combustion, pyrolysis does not involve reaction with water, oxygen or other reagents. However, as it is practically not possible to achieve an oxygen- free environment, a small amount of oxidation always occurs in any pyrolysis system.
