Abstract
The development of a new class of ion-exchange resins which possesses macro-porosity superimposed on a conventional ion-exchange gel structure presents new kinetic problems. This paper considers the kinetics of this class of catalysts and presents the general analytical solution for a steady-state first-order reversible-reaction situation. The effect of pertinent physical parameters on both the concentration profiles and on reaction rate is indicated. Limiting rates for high surface area catalysts are predicted, and an estimate of the optimum catalyst porosity necessary to achieve maximum volumetric activity is presented. Finally, the maximum rate advantage of this new class of catalysts over conventional ion-exchange catalysts is noted.
