摘要

Pyrolysis is the thermal degradation of a substance in the absence of oxygen or other agents, although steam is used sometimes.This process requires an external heat source to maintain the temperature required.Typically, relatively low temperatures of 300-850°C are used during pyrolysis of materials such as MSW.The products produced from pyrolysising materials are a solid residue and a synthetic gas (syngas).The solid residue (sometimes described as a char) is a combination of non-combustible materials and carbon.The syngas is a mixture of gases (combustible constituents include carbon monoxide, hydrogen, methane and a broad range of other VOCs), a proportion of which can be condensed to produce oils, waxes and tars.If required, the condensable fraction can be collected by cooling the syngas, potentially for use as a liquid fuel.Anhydrous pyrolysis occurs when a solid organic material is heated without oxygen.Frying, baking, toasting and roasting are examples of pyrolysis, as the outer layer of the food changes as it is heated, but the inside doesn't.Charcoal is produced by the pyrolysis of wood.Flames in a wood fire are caused by gases combusting as a result of pyrolysis, not the act of burning wood itself.As a result of this, pyrolysis is important for those involved in fire safety.
