Noun
pyrolysis (countable and uncountable, plural pyrolyses)
- (chemistry, physics) The decomposition of a material or compound due to heat, in the absence of oxygen or other reagents.
- 1972, A. C. Knipe, Chapter 4: Elimination Reactions, B. Capon, C. W. Rees (editors), Organic Reaction Mechanisms 1971, page 143,
- Techniques that have successfully identified ionic intermediates in solution have been applied to gas-phase pyrolyses.
- 1980, J. H. Purnell, Homogeneous Alkane Cracking, William Pryor (editor), Frontiers of Free Radical Chemistry: The route to quantitative description to very high conversion, page 94,
- Twenty years ago our real understanding of the mechanism of alkane pyrolyses was little better than rudimentary.

- Pyrolysis involves the thermal degradation of the rubber of the tyre to give an oil and gas leaving a residual solid carbon and the steel casing of the tyre.
- 2006, John C. F. Walker, Primary Wood Processing: Principles and Practice, 2nd Edition, Springer, page 541,
- Traditional pyrolysis of wood relies on low temperatures and long processing time to increase the charcoal yield. In contrast, modern or fast pyrolysis uses moderate temperatures (400-500°C) and very short residence times (typically only a few seconds) to maximize the production of liquids (Diebold and Bridgewater, 1997).
