A one-dimensional model of the catalytic combustion of propane over a catalyst slab in non-stationary state was formulated. Due to the high value of the BiH number adapted the system exhibited internal temperature gradients. The numerical experiments conducted demonstrated unsteady aspects of ignition/extinction of reaction in non-stationary and cyclic stationary states. The model was further used to investigate the warm-up/light-off characteristics of the system with the high value of the Bih number, the effect of short disturbances on extinction behaviour and the effect of cyclic operation on yield and temperature histeresis.
