The Non-linear Analysis of the Chemical Reaction Models of Three-variable Consecutive Exothermal Reactions in CSTR

This paper is concerned with the non-linear kinetic phenomenon of the three-variable chemical models with two consecutive exothermal reactions in CSTR. The non-dimensional mathematic model of the chemical model is established and analyzed qualitatively by numerical simulation. It is seen from the results of the numerical simulation that the rich non-linear kinetic phemomenon can be obtained by changing thermal feedback, and the reactions are controlled by the change of the Newton cooling time τ^N and non-dimensional active energy ε. Chemical oscillations and chemical chaos can be obtained by changing τ^N in a certain sphere under the condition that the ε and other parameters are determined.
