Primary elementary reactions in low temperature combustion
Elementary reactions of propane oxidation are reported, showing the main reaction classes of combustion processes. Propane gives clear evidence of the competing alternatives of decomposition, oxygen addition, isomerisation and cyclisation to form C(3)H(6)O. From experimental data on neopentane oxidation, it is possible to define rate values for elementary reaction steps and standard kinetic parameters for oxygen addition and internal isomerisation of alkyl and peroxy radicals. This can then be extended to heavier hydrocarbons and main reaction classes. The analysis shows the strong correlations between knocking properties and fuel structures. Methyl transfer and methyl shift reactions seem to be particularly important when fuel hydrocarbon contains quaternary and tertiary carbon atoms.
