In the recent global warming increase, the demand for less pollutants energy sources and fuels is growing substantially. For this reason, the hydrogen production has been targeted by research and studies. The production of this gas from methane partial oxidation in membrane reactors is showing to be a good alternative. In this work, hydrogen production process through a membrane reactor should was studied by a simulation and modeling point of view. A mathematical model of a membrane reactor assuming one dimension, isothermal and steady state conditions was used. Simulations were made to compare the reactor conversions in different membrane dense type compositions. The molecular structures of the membranes perovskite-type were considered, that is, ABO3. Mathane and hydrogen conversions were evaluated, as well as the composition profiles through the reactor length. A comparison between the performances of the partial oxidation and steam reforming processes was made. In membrane reactors, the reaction process and the separation step are combined in the same device. This provides a cost reduction in production of many important substances, as for example, syngas
