Pyrolysis oil, sometimes also known as biocrude or bio-oil, is a synthetic fuel with few industrial application and under investigation as substitute for petroleum.It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling, separation from the aqueous phase and other processes.
Pyrolysis is used to turn organic materials into carbon for the purpose of carbon-14 dating. Pyrolysis liquids from slow pyrolysis of bark and hemp have been tested for their antifungal activity against wood decaying fungi, showing potential to substitute the current wood preservatives [99] while further tests are still required. However, their ...
Pyrolysis gasoline or pygas is a naphtha-range product with high aromatics content. [1] It is a by-product of high temperature naphtha cracking during ethylene and propylene production, a high octane number mixture that contains aromatics from the aromatization reactions, olefins , and paraffins ranging from C5s to C12s.
[2] [3] The process has also been called hydrous pyrolysis. The reaction usually involves homogeneous and/or heterogeneous catalysts to improve the quality of products and yields. [ 1 ] Carbon and hydrogen of an organic material, such as biomass, peat or low-ranked coals ( lignite ) are thermo-chemically converted into hydrophobic compounds ...

Catalytic fast pyrolysis is a fast process in which the cellulose is broken down to a liquid biofuel. In this approach the cellulose is heated to 500 degrees Celsius in less than one second in a chamber to break apart the molecules. The catalyst forms chemical reactions that remove oxygen bonds and form carbon rings
Pyrolysis GC/MS chromatogram of mahogany wood analyzed with OpenChrom. Pyrolysis–gas chromatography–mass spectrometry is a method of chemical analysis in which the sample is heated to decomposition to produce smaller molecules that are separated by gas chromatography and detected using mass spectrometry.

Liquid smoke is a water-soluble yellow to red liquid [1] used as a flavoring as a substitute for cooking with wood smoke while retaining a similar flavor. It can be used to flavor any meat or vegetable.
