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 ...
This property of NBCA has made it a very useful polymer to create various nanoparticles for delivery of drugs into the body with sustained release profiles. Heating to higher temperatures causes pyrolysis and depolymerization of the cured glue, producing gaseous products strongly irritating to lungs and eyes.
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.

One can produce a tar-like substance from corn stalks by heating them in a microwave oven. This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1]
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.
