Development of a detailed kinetic reaction mechanism for the oxidation of n-octane and iso-octane
The development of detailed chemical kinetic reaction mechanisms for the oxidation of n-octane and iso-octane is described. The elementary reactions describing the thermal decomposition and H atom abstractions of the octane molecules, the thermal decomposition reactions of the resulting alkyl radicals, and the abstraction and addition reactions of the intermediate olefin and other species are discussed. In many cases, the assignment of specific rate expressions for these reactions is made, and the identification of probable reaction products is attempted. The reaction mechanisms for the two forms of octane are compared and contrasted, and the relationships between the two mechanisms are used to explain some of the observed differences in the combustion characteristics of the two fuels. 22 refs.
