Abstract

The steady state reaction-diffusion problem for a permeable catalytic particle is considered, when the reaction rate is of the Langmuir-Hinshelwood type and the activation energy is large. It is shown that there are multiple solutions for the Damkohler number belonging to a certain interval. An arbitrarily large number of solutions appear for symmetric particles: (a) in two dimensions if the adsorption effects are sufficiently important and the reaction order is negative, and (b) in three dimensions. An asymptotic analysis provides approximate analytical expressions for the response curves and for the multiplicity bounds.
