Possibilities of the control of an adiabatic stirred flow reactor with an exothermic first order reaction in unstable state are studied. The control is studied both on the linearized mathematical model and on the model reaction of oxidation by hydrogen peroxide catalyzed by ferric ions. The control is based on step changes in the volume of the reaction mixture at constant conditions at the reactor inlet. The aim is stabilization of the outlet degree of conversion of the reactant. From the theoretical study on the mathematical model resulted that control of the reactor by step changes of the volume can be a very simple and effective method of control in the unstable steady state. The results of theoretical studies have been verified experimentally.
