A heterogeneous fixed bed reactor model was developed for the OCM reaction over La2O3/CaO catalyst. The pore diffusion resistance was found to be more important in evaluating the system performance than was the external mass transfer resistance. The model we developed was simulated under various conditions of operation. The results obtained from the simulation under isothermal operation (CH4/O2=9; T =973 K; mcat/vSTP = 250 kg s/m3) gave a 2% yield for the C2 product and a 10% selectivity for ethylene. In the membrane reactor simulation, we obtained an ethylene yield of 23% and a methane conversion of 40% at 1073 K under the optimum flux-to-methane flow rate ratio of 1.5X10-3.
