Abstract

This cyclohexane reaction sub-model for high and low temperature oxidation has been developed on the base of the DLR C0-C4 kinetic model with the PAH formation. The reaction model was successfully validated on the experimental data for ignition delay measured in rapid compressor machine and shock tube experiments, laminar flame speed data and the species concentration profiles measured in laminar flames at low and atmospheric pressure. The chemical pathways leading to the PAH formation are well understood. For temperatures lower than 1200K, the cyclohexane dehydrogenation is the dominant way to produce benzene. At higher temperatures, propargyl recombination is the dominant way.
