The hydrocarbon steam reforming is a industrial process for procuding hydrogen and carbon monoxide. The reaction is strongly endothermic and operating temperature is very high. The reaction is following: CH4 + H2O <==> H2+CO At the end of the process in reformer stream, there is high CO presence, pollutant for a lot of catalyst. To improve H2 production, CO is reacted with steam (water gas shift reaction) in presence of Fe-Cr and Cu-Zn catalyst at high and low temperature. Nowday, the PSA (pressure swing adsrober) is used for H2 purification. A novelty metod to produce and purify H2 is to use a membrane reactor. An experimental study has been conducted varying the operating condition such as: Temperature and pressure reaction, space velocity, H2/CO feed molar ratio, membrane surface, sweep gas and membrane reactor configuration. In all test, the H2 purity was 100%.
