Hydrogen production from ethanol steam reforming over xNi/15 %La2O3-10 %CeO2-gamma-Al2O3 (x = 5, 10 and 15 wt %) catalysts was investigated with an ethanol:water = 1:3 feed composition. The results of catalysts characterization suggest that Ni metal particles have a strong metal support interaction with the promoters on the surface. Ethanol was completely converted to hydrogen and C-1 products (CO, CO2, CH4) even at 723 K due to the remarkable C-C bond cleavage capacity and resistance to coke formation conferred by the promoters at low metal loadings. The increase of Ni particle size decreases the stability and selectivity; catalyst deactivation during 24 h on stream was attributed to coke deposition. [GRAPHICS]
