Pyrolysis is an ancient method of decomposing solid matter by heating to high temperatures examples are production of metals, coke furnaces, and obtaining of chemicals from coal prior to petroleum. There are many kinds of pyrolysis batch, semi-batch or continuous catalytic or non-catalytic out under vacuum or at atmospheric or high pressure. Its medium may be inert, oxidative or reductive. Heating rate, temperature, and time are important pyrolysis parameters. 

Free-fall reactors (FFR) are a good choice for rapid or flash pyrolysis. They have been widely harnessed to pyrolyze coal and, more recently, biological mass. A pioneering group at Ankara University was the first to attempt pyrolysis of waste plastics in a FFR. Then-results are very promising indeed compared with other alternatives in the literature.
