• Regeneration of coked zeolite catalyst is carried out in a non-adiabatic fixed bed reactor and the experimental results are simulated with a one-dimensional model. Reactor behavior which shows a relatively small temperature rise can be simulated well. With greater temperature rise, the agreement between experimental and calculated results becomes unsatisfactory. The comparison of simulation is discussed in terms of stability criterion. A measure of stable conditions in catalyst regeneration is derived from Inoue''s criterion for the formation of hot spot. It is shown that the one-dimensional model is usable to simulate reactor behavior in catalyst regeneration if the experimental conditions satisfy Inoue''s criterion.
