Because propane is the simplest hydrocarbon which exhibits characteristics similar to those of more complex fuels, a thorough study of the pyrolysis and oxidation of propane was undertaken in the Princeton turbulent flow reactor. The pyrolysis rate was found to first order with respect to the fuel with a pre-exponential factor of 3.2 x 10 to the 12.5 power and activation energy of 86.65 kcalmole. A detailed mechanism was developed which fits a wide range of data and indicates that the literature values for the rate constant for the reaction methyl plus propane would be in error. This and earlier work with hydrocarbon oxidation provided the means for developing an overall kinetic scheme for all aliphatic hydrocarbon oxidation which would accurately predict major species formed and the temperature-time history rate of heat release of the reaction.
