✦ Synopsis

A stability analysis concerning bifurcation to periodic solutions of steady-state solutions has been performed for a model which describes transport phenomena and chemical reaction in a porous catalyst pellet. Extensive numerical simulations have revealed the existence of three scenarios for the generation of self-excited oscillations of the mixture temperature and composition inside the pellet. These are the supercritical and subcritical bifurcations to oscillatory solutions, which occur in the region of single steady-states, and the homoclinic bifurcation in the region of multiple steady-states.

Based on the method developed by Berezowski and Burghardt (1993) for analysing the bifurcation to oscillatory solutions, the effect of the reaction order on oscillatory destabilization of a catalyst pellet is studied. A linear analysis of the dynamics of the system enabled a relationship to be deter
