A comprehensive combustion chemistry study of n-propylcyclohexane

Alkylated cycloalkanes are vital components in gasoline, aviation, and diesel fuels; however, their combustion chemistry has been less investigated compared to other hydrocarbon classes. In this work, the kinetics of n-propylcyclohexane (n-Pch) was studied across a range experiments including pressurized flow reactor (PFR), jet stirred (JSR), shock tube (ST), rapid compression machine (RCM). These cover wide conditions spanning low intermediate high temperatures, pressures at lean rich equivalence ratios. Stable species were measured PFR over temperature 550–850 K, pressure 8.0 bar, ratio (φ) 0.27, constant residence time 120 ms. The JSR utilized measure speciation during oxidation n-Pch φ 0.5–2.0, atmospheric pressure, 550–800 K. Ignition delay times (IDTs) for RCM ST temperatures ranging from 650 1200 20 40 φ=0.5,1.0. addition, comprehensive detailed chemical kinetic model developed validated against experimental data. new model, coupled with breadth data various experiments, provides an improved understanding combustion.
