Pyrolysate

Part of speech: noun

Definitions

1. A product created through the thermal breakdown of organic substances in the absence of oxygen, resulting in various chemical compounds
2. This material is formed when organic matter undergoes thermal degradation without oxygen, yielding diverse chemical outputs
3. A substance resulting from the high-heat decomposition of organic materials in an oxygen-free environment, producing a range of chemical compounds

Etymology: Pyrolysate is a modern technical coinage built from Greek. Its first part, "pyro-," comes from "pyr," meaning fire, and the second part, "-lysis," comes from "lysis," meaning a loosening or breaking apart, from the Greek verb "lyein." Chemists joined these to name the breakdown of a material by heat alone, without oxygen, and the resulting "pyrolysis" is the process itself. The ending "-ate" follows the pattern of nouns like "distillate," which name what a process produces. So a pyrolysate is whatever remains or is released when a material has been broken down by heat. Such products can be gases, liquids such as tars and oils, or solid residues like char.
