Abstract

The kinetics of the initial step of methane oxidation in a wide range of the external parameters is studied using a simplified model including complete branched cycles of peroxide formation and decomposition. An analytical formula for the ignition criterion is obtained by analysis of the structure of the reaction scheme (graph). Qualitative assessment and calculation of the critical parameters of this criterion in the framework of a linear model provide a new notion of the configuration of the methane chain ignition region. This notion implies that the kinetics and product composition vary in going from one portion of the ignition region boundary to another and provides an explanation for this behavior. The evolution of the system in the region itself is discussed in terms of nonlinear contributions to the dependence of the criterion on the parameters.
