Kinetic Models in Heterogeneous Catalysis

The role and importance of chemical kinetics in heterogeneous catalysis at the present stage of development are examined and the concept of kinetic models, in the exact, reliable, complete, and well-founded form, as well as the usefulness of combined kinetic investigations for the determination of these models are discussed. The effectiveness of combining different methods for devising informative models of this kind, examples of which are quoted, is demonstrated. The problems involved in setting up non-steady-state kinetic models, which are some of the most important in chemical kinetics, are briefly described. The optimum characteristics of kinetic models and the relation between the properties of the latter and the characteristics of reaction selectivities are analysed. The kinetic aspects of tests of the activities and selectivities of catalysts of complex reactions are mentioned in conclusion. © 1978 Turpion Ltd. All rights reserved.
