  2. Charring - Wikipedia

    en.wikipedia.org/wiki/Charring

    Charring is a chemical process of incomplete combustion of certain solids when subjected to high heat. Heat distillation removes water vapour and volatile organic compounds from the matrix. The residual black carbon material is char, as distinguished from the lighter colored ash.

  3. Soot - Wikipedia

    en.wikipedia.org/wiki/Soot

    Soot forms during incomplete combustion from precursor molecules such as acetylene. It consists of agglomerated nanoparticles with diameters between 6 and 30 nm . The soot particles can be mixed with metal oxides and with minerals and can be coated with sulfuric acid .

  4. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

  5. Endothermic gas - Wikipedia

    en.wikipedia.org/wiki/Endothermic_gas

    An endothermic gas generator could be used to supply heat to form an endothermic reaction. [ 1 ] Synthesised in the catalytic retort(s) of endothermic generators, the gas in the endothermic atmosphere is combined with an additive gas including natural gas , propane (C 3 H 8 ) or air and is then used to improve the surface chemistry work ...

  6. Flame - Wikipedia

    en.wikipedia.org/wiki/Flame

    For instance, a well-known chemical kinetics scheme, GRI-Mech, [6] uses 53 species and 325 elementary reactions to describe combustion of biogas. There are different methods of distributing the required components of combustion to a flame. In a diffusion flame, oxygen and fuel diffuse into each other; the flame occurs where they meet.

  7. Adiabatic flame temperature - Wikipedia

    en.wikipedia.org/wiki/Adiabatic_flame_temperature

    Incomplete reaction at higher temperature further curtails the effect of a larger heat of combustion. [citation needed] Because most combustion processes that happen naturally occur in the open air, there is nothing that confines the gas to a particular volume like the cylinder in an engine.

  8. Benzene - Wikipedia

    en.wikipedia.org/wiki/Benzene

    The empirical formula for benzene ... It is a byproduct of the incomplete combustion of many materials. ... The aromatic products of the reaction are then separated ...

  9. Polycyclic aromatic hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Polycyclic_aromatic...

    A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings.Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [1] or when biomass burns at lower temperatures as in forest fires.
