pyrolysis
- Noun:
- The chemical decomposition of a substance caused by heating it to a high temperature, typically in the absence of oxygen: "Pyrolysis" refers to a process where heat breaks down materials into smaller molecules without combustion.
- "Pyrolysis" is a technical term used primarily in chemistry, engineering, and environmental science. It describes a specific thermochemical process.
- It is typically used as an uncountable noun (e.g., "the pyrolysis of plastic").
- The process results in the production of gases, liquids (like bio-oil), and a solid residue (char).
- Noun:
- The pyrolysis of wood produces charcoal and various volatile compounds.
- Advanced pyrolysis techniques are being developed to convert waste plastic into fuel.
- The study focused on the pyrolysis kinetics of different biomass materials.
"Catalytic pyrolysis": Pyrolysis that uses a catalyst to lower the required temperature or to influence the products formed.
- Catalytic pyrolysis can improve the yield of desirable hydrocarbons from plastic waste.
"Fast pyrolysis": A type of pyrolysis characterized by very high heating rates and short residence times to maximize liquid product yield.
- Fast pyrolysis is optimized for producing bio-oil from agricultural residues.
"Pyrolysis gas": The mixture of gases produced during pyrolysis.
- The pyrolysis gas can be cleaned and used to generate power for the facility.
Pyrolyze (verb, also spelled pyrolyse): To subject a material to pyrolysis.
- The reactor is designed to pyrolyze tires efficiently.
Pyrolytic (adjective): Relating to or produced by pyrolysis.
- The pyrolytic carbon coating is very durable.
Pyrolyser/Pyrolyzer (noun): A device or apparatus in which pyrolysis is carried out.
- The new mobile pyrolyzer can process biomass on-site.
- Thermal decomposition: A broader term for breakdown by heat, which can include pyrolysis.
- Cracking: A similar process used in petroleum refining, though often with catalysts and specific to hydrocarbons.
- Destructive distillation: An older term for pyrolysis, especially of organic materials like coal or wood.
Pyrolysis oil: The liquid product of pyrolysis, also called bio-oil.
- Pyrolysis oil can be upgraded to transportation fuels.
Pyrolysis temperature: The specific temperature range at which pyrolysis occurs for a given material.
- The optimal pyrolysis temperature for this polymer is 450°C.
Flash pyrolysis: A very rapid form of pyrolysis.
- Flash pyrolysis is used to obtain high yields of condensable vapors.
-
transformation of a substance produced by the action of heat
