A mathematical model of an oxygen permeable dense ceramic hollow membrane reactor packed with a Ni/gamma-Al2O3 catalyst for the partial oxidation of methane (POM) to syngas has been developed. With the present model, various operating conditions such as temperature, operating pressures and feed con cent rat ions affecting the performance of the reactor were investigated theoretically. The applied membrane area plays the key role in the operation of the membrane reactor. Assuming that the La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) membrane is stable under the pressures and temperatures operated, the optimum membrane area required for the POM to syngas is predicted to be varied from 98 to 16 cm(2) per cm(3)/s (STP) of methane feed when the operating temperatures are increased from 1148 to 1248 K. In order to run the membrane reactor economically and safely, the pressures in both shell and lumen sides should be kept close to one atmosphere.
