Experimental and Kinetic Modeling Study of 3-Methyl-2-butenol (Prenol) Oxidation

Longer chain alcohols with 4–5 carbon atoms are attractive alternative fuels as they can be derived from biological sources and since their combustion leads to lower exhaust gas levels of NOx soot compared commercial fossil fuels. The auto-ignition behavior that contain both a hydroxyl group C═C double bond in molecular structure is not well established the literature. Understanding influence these functional groups on ignition critical development tailor-made for advanced engines. In this study, delay times an unsaturated alcohol, 3-methyl-2-butenol (prenol), measured using high-pressure shock tube rapid compression machine at pressures 15 30 bar equivalence ratios 0.5, 1.0, 2.0 “air” temperature range 600–1400 K. A detailed kinetic model developed validated new experimental data study. addition, speciation jet-stirred reactor, times, laminar burning velocities available literature were also used validate model. Fuel flux sensitivity analyses performed determine important fuel consumption pathways reactions affect reactivity prenol.
