Abstract:
This paper presents a kinetic analysis of a chemical model for the oxidative conversion of methane which includes all possible elementary reactions that can occur in this complex radical chain process. It is found that the model fully reflects the kinetic features of degenerate-branched chain reactions. The key stages of the process responsible for the formation of the main reaction products and the development of the process as a whole are identified. The nonlinear reactions of free peroxide radicals play a decisive role in these stages. The results of the kinetic analysis of the model confirm the previously obtained direct experimental data on free radicals and their kinetic behavior during methane oxidation.
