AnnotationThe results of mathametical modeling of self-sustained oscillations in methane oxidation reaction over metallic catalysts are presented. The model contains the singluar perturbations under some conditions. We determined the parameters at which both the degenerated and initial systems have the stable limit cycle. The dependences of the shape and the period of the oscillations on the parametes are studied to describe the experimental data.
