Combustion chemistry of alkenes and alkadienes

Alkenes formed, during the refining of crude oil, by cracking heavier fractions are present in transportation fuels significant amounts, up to as much 15–20% gasoline. Moreover, alkenes also major intermediate products oxidation alkanes, which play a role autoignition chemistry. This review has assessed recent progress gas-phase detailed kinetic model development for species with C=C double bond, mostly C2–C10 and 1,3-butadiene. The compiled knowledge on alkene combustion chemistry enabled better understanding influence number position bond chemical kinetics hence behavior engines. At first, article gives an extensive overview fundamental experiments considering studies 1,3-butadiene shock tubes, rapid compression machines, laminar flames, jet-stirred flow reactors. value data from such is critically discussed. Secondly, this highlights important reaction classes involved over low-, intermediate- high-temperature ranges. Combustion covering C2 C10 alkenes, special emphasis C7 isomers discussed presenting large body experimental modeling investigations. Detailed differences between alkanes addressed. Thirdly, presents pathways PAH precursor formation different alkenes. Finally, summary distinguishing features outlook towards future research area presented. focused linear branched chain cyclo-alkenes not included.
