Abstract
Hydrogen production from ethanol steam reforming over xNi/15 %La2O3–10 %CeO2–γ-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 C1 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.
