Pyrolysis definition: the application of heat to chemical compounds in order to cause decomposition | Meaning, pronunciation, translations and examples. Pyrolysis is a thermochemical treatment, which can be applied to any organic (carbon-based) product. 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 is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It involves the change of chemical composition and is irreversible. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating".‎Pyrolysis · ‎Hydrous pyrolysis · ‎Charring · ‎Carbonization.

Pyrolysis | Student Energy

VolumeMay 10, The fuels produced are considered second generation fuels since the pyrolysis definition stocks are from renewable sources, like waste and biomass.

As a result, they are less carbon-intensive than fossil fuels.


These fuels are also compatible with our existing transportation infrastructure which eliminates the need to introduce costly new infrastructure. Pyrolysis does have higher costs associated with the machinery and heating and is dependent on a supply of cheap biomass [3] United States Environmental Pyrolysis definition Agency.

Pyrolysis can help break down vehicle tires into useful components, thus reducing the environmental burden of discarding the tires. Tires are a significant landfill component in many areas, and they release PAHs and heavy metals into pyrolysis definition air when they are burned.

However, when tires are pyrolyzed, they break down into gas and oil usable for fuel and carbon black usable as filler in rubber products, including new tires, and as activated charcoal in filters and fuel cells.

It also pyrolysis definition in fires where solid fuels are burning or when vegetation comes into contact with lava in volcanic eruptions. In general, pyrolysis of organic substances produces gas and liquid products and leaves a solid residue richer in carbon content, char.

In this treatment, material is exposed to high temperature, and in the absence of oxygen goes through chemical and physical separation into different molecules. This allows to receive products with a different, often more superior character that original residue.

Conversely, the starting material may be heated in a vacuum to decrease the boiling point of the byproducts and avoid adverse chemical reactions.

An example is the process of flash pyrolysis definition pyrolysis used in organic synthesis.

Volatile pyrolysis byproducts can be analyzed through separation by gas chromatography and identification by mass spectrometrya process known as Py-GC-MS. The resulting ethylene is used to make antifreeze ethylene glycolPVC via vinyl chlorideand many polymers, such as polyethylene and polystyrene.

Consequently, pyrolysis is used to produce many kinds of pyrolysis definition these can be used for fuel, as reagents in steelmaking cokeand as structural materials.


High temperature pyrolysis is used on an industrial scale to convert coal into coke for metallurgyespecially steelmaking. Volatile products pyrolysis definition often useful, including pyrolysis definition and pyridine.

The original vascular structure of the wood and the pores created by escaping gases combine to produce a light and porous material.
