Pyrolyzed

Part of speech: verb

Definitions

1. The chemical transformation of organic matter occurs through heating in a low or no-oxygen setting, resulting in the formation of gases and solid residues
2. This method involves the high-temperature breakdown of materials without oxygen, leading to the production of volatile compounds and solid byproducts
3. The process involves heating organic substances in the absence of oxygen, which results in the conversion of the matter into gases and charred residuals

Etymology: "Pyrolyzed" is the past tense and past participle of "pyrolyze," a verb meaning to decompose a substance by heating it in the absence of oxygen. The verb is built from two Greek elements: "pyr," meaning fire, and "lyein," meaning to loosen or break apart. Together they describe what happens when fire takes something apart rather than burning it away. The "-lyze" ending is the same Greek root found in "analyze" and "catalyze," so the verb belongs to a family of scientific words that break things down into their components. Because the process happens without oxygen, the substance splits into new materials rather than combusting into ash and gases.

Synonyms: thermally decomposed
