چکیده انگلیسی
Oxidative steam reforming of ethanol for hydrogen production in order to feed a solid polymer fuel cell (SPFC) has been studied over several catalysts at on board conditions (a molar ratio of H2O/EtOH and of O2/EtOH equal to 1.6 and 0.68 respectively) and a reforming temperature between 923 and 1073Â K. Two Ni (11 and 20Â wt.%)/Al2O3 catalysts and five bimetallic catalysts, all of them supported on Al2O3, were tested. The bimetallic catalysts were Ni (approximately 20Â wt.%) based catalysts doped with Cr (0.65Â wt.%), Fe (0.6Â wt.%), Zn (0.7Â wt.%) or Cu (0.6 and 3.1Â wt.%). The results in terms of H2 production and CO2/COx ratio obtained over Ni-based catalysts supported on Al2O3 are compared with those obtained over Ni-Cu/SiO2 and Rh/Al2O3 catalysts reported in our previous works. Tendencies of the product selectivities are analyzed in the light of the reaction network proposed.
