 Traditional processes are composed by a steam reforming section, to produce syngas from natural gas, two water gas shift reactors which enhance hydrogen in syngas and a pressure swing adsorption unit for hydrogen purification.Membrane reactors make a process intensification including all these sections in one single unit, with both economic and environmental benefits.To be suitable for hydrogen production industry, membranes must have an high flux, high selectivity towards hydrogen, low cost and high stability.
