Thiswork is focused on the performance prediction of pilot scale catalytic reverse flow reactors used for combustion of lean methane-air mixtures. An unsteady one-dimensional heterogeneous model for the reactor was established to account for the influence of the reactor wall on the heat transfer. Results of the simulation indicate that feed concentration

switch time and compensatory temperature impose important influence on the performance of the reactor. The amount of the heat extracted from the mid-section of the reactor can be optimized via adjusting the parameters mentioned above. At the optimal operating conditions

i.e. switching time of 400 s

feed concentration of 1% (by volume)

and insulation layer temperature of 343 K

the axial temperature of the reactor revealed a comparatively symmetrical "saddle" distribution

indicating a favorable operating status of the catalytic reverse flow reactor.
