Autooscillations in a perfectly stirred reactor with a two-step consecutive reaction

A mathematical model of the dynamic behavior of a perfectly stirred reactor in which a two consecutive exothermic reactions occurs is developed. Both stages are exothermic. In the Da-Se parametric space, the region of autooscillations (limiting cycles) is identified. The character of alternation of the stabilities of steady states is investigated. It is shown that, in the region of one steady state, two mechanisms of formation (disappearance) of limiting cycles are realized.
