Pyrolysis, английский
- Пиролиз
- A chemical change brought about by the action of heat, usually in the absence of a reactive medium. complex chemical molecules are reduced to simpler chemical units as a result of pyrolysis. q
- Pyrolysis is the process of heating organic material at high temperatures in the absence of oxygen or any other oxidizer. the term pyrolyze is used when subjecting a substance to pyrolysis. pyrolysis involves the simultaneous change of chemical composition and physical phase, and is irreversible. pyrolysis is not combustion and the compounds produced by pyrolysis are generally different than those produced by combustion or incomplete combustion. pyrolysis has been used since ancient times for turning wood into charcoal. charcoal is obtained by heating wood in the absence of air until its complete pyrolysis (carbonization) occurs, leaving only carbon and inorganic ash.
- A process in whcih material is decomposed, or broken down, into simpler molecular compounds by the effect of heat alone; pyrolysis ofter precedes combustion.
- The process in which material is decomposed, or broken down, into smaller molecular compounds by the effects of heat alone; pyrolysis often precedes combustion.
