Abstract: A self-started OSRM (oxidative steam reforming of methanol) process at evaporation temperature of aqueous methanol for hydrogen production is disclosed. In the process, an aqueous methanol steam and oxygen are pre-mixed. The mixture is then fed to a Cu/ZnO-based catalyst to initiate an OSRM process at evaporation temperature of aqueous methanol. The temperature of the catalyst bed, with suitable thermal isolation, may be raised automatically by the exothermic OSRM to enhance the conversion of methanol.
