Oscillatory Behavior during the Partial Oxidation of Methane

A simplified Monte Carlo model was proposed to simulate the oscillatory behavior during catalytic partial oxidation of methane. Using the Langmuir-Hinshelwood mechanism, the oscillatory behavior was observed in both reaction rates and coverages of adsorbed species. The influence of oxidation and reduction of the catalyst surface on the oscillations was investigated, and the analysis showed that the fast oxidation and slow reduction of the catalyst surface resulted in the oscillatory behavior.
