| Abstract: | The transient response method has been applied to discriminate between rival kinetic models derived from the conventional Hougen-Watson procedure in heterogeneous catalysis, by using some old data for the NO-CO reaction, dehydrogenation of sec-butanol, hydrogenation of phenol, and dehydrogenation of tert-butanol. A computer technique is commonly used for the simulation of the transient response curves of products caused by the concentration jump of reactants in a flow type reactor. The shapes of the calculated response curves are of various characteristic types (depending on the given model) which allow for easy discrimination between rival kinetic models. The difficulty of the discrimination in some particular models is also discussed. |
