Abstract

This paper describes a method for evaluating the kinetic consts. in a rate expression for catalytic combustion applications using exptl. light-off curves. The method uses a transient one-dimensional single channel monolith finite element reactor model to simulate reactor performance. The heat and mass transfer models used account for developing flow in the entrance region. A parameter global optimization routine based on a generalized pattern Search algorithm is used to det. the best fit parameters in the rate expression for the oxidn. of CO and mixts. of CO and CH4. The algorithm is compared to a more classical gradient method, the Fletcher-Reeves method.
