✦ Synopsis

During methane oxidation initiated by nitric acid or nitrogen dioxide, it is possible to observe, under certain conditions of temperature, initiator content, and flow rates, the formation of an adiabatic "temperature peak." Because the maximum temperature of the peak does not exceed the initial temperature of the reactor by more than 220°C, the recorded temperature-increase curves were used for a kinetic interpretation. The obtained kinetic parameters (overall n and E ) agree with the values reported in the literature for isothermal methane oxidation and suggest that the overall mechanism does not change in the conditions of "temperature peak.
