Ethanol steam reforming reactions over Al2O3 . SiO2-supported Ni–La catalysts

Abstract. Nickel-based catalysts supported on Al2O3 . SiO2 were prepared with modification of the second metal involving La, Co, Cu, Zr or Y, of which the catalytic behaviors were assessed in the ethanol steam reforming reaction. Activity test indicated that addition of La resulted in higher selectivity of hydrogen and lower selectivity of carbon monoxide, compared with Co-doped nickel cat…
