Mechanism of ethanol steam reforming into syngas over Pt/ Pr0.15Sm0.15Ce0.35Zr0.35O2 and
10wt.% LaNi0.95Ru0.05O3/Mg-Al2O3 catalysts was studied by in situ FTIRS. Surface species (ethoxy, adsorbed ethanol, acetaldehyde, acetate) were identified and their thermal stability and reactivity were estimated. Transformation of ethoxy species by dehydrogenation is a fast step, while the ratedetermining stage is the C-C bond rupture in thus formed acetaldehyde at metal sites. Acetate species are spectators, while transformation of ethoxy species on acid sites of alumina-supported catalyst produces C2H4 and (C2H5)2O via dehydration route.
