Design and experimental verification of a nonlinear catalytic reactor estimator

Abstract A procedure for the implementation of a nonlinear extended Kalman filter to infer the outlet concentration of a catalytic reactor from temperature measurements is developed. The role of the reactor model in determining the reliability of the conversion estimates is discussed in detail. The estimator performance is checked by comparison with the dynamic experimental behavior of a catalytic reactor where the oxidation of CO to CO 2 is carried out on a Pt—alumina-supported catalyst. The application of the developed estimation procedure to reactors of interest in applications is discussed.
