The combustion of methane was studied in a fixed bed reactor to determine the effect of inert particles through heterogeneous and homogeneous reactions. Methane and CO 2 mole fractions are measured at the reactor outlet. The results show that any accelerating catalytic effect of the inert particles is quite small, while considerable inhibition effect was found at moderately high temperatures. A plug flow model with a complete and reduced reaction scheme was developed to explain the experimental findings. Both reaction schemes fail to fully predict the experimental data. Therefore, an improved combined mechanism is proposed, which is now able to predict the experimental data.
