A three variable thermokinetic model of ignition is devised to describe the gas-phase oxidation of hydrocarbons in CSTR. For a single set of thermokinetic parameters, the model displays steady states, bistability, cool flame oscillation, simple ignition oscillation, and complex ignition-cool flame oscillations, when the reactant pressure P and vessel temperature T0 are varied as control parameters. The predicted P-T0 state diagram compares fairly well with the experimental finding for the system of acetaldehyde/oxygen. The model also predicts interesting bifurcation sequences of complex periodic states. The proposed skeleton model is justified qualitatively by considering detailed kinetics in the oxidation of acetaldehyde.
