Regime stability of a cascade of continuous stirred reactors operated isothermally is analyzed for a reaction with autocatalytic type of kinetic law. Consequences of the regime unstabilities are discussed and control algorithms suggested to operate the cascade in both stable and unstable operating points. Numerical simulations are used to test the algorithms. Reaction calorimetry serves as the source of information on the reactor state in conversion control in unstable states if no on-line analytical method is available to measure conversion.
