چکیده انگلیسی
The effect of iron promoter on cobalt-based catalysts, active in the ethanol steam-reforming, was studied. FexCo3-xO4(0⩽x⩽0.60)FexCo3-xO4(0⩽x⩽0.60) oxides prepared by co-precipitation and an Fe-doped Co3O4Co3O4 prepared by wetness impregnation are analysed. The activation process of the oxides under reaction conditions was studied by in situ X-ray diffraction (XRD); the activation depended on the iron content of the oxides. The systems were characterized by means of temperature programmed reduction (TPR), XRD and tested in the ethanol steam-reforming reaction at 623–673 K. An optimal iron loading that gives rise to a high H2selectivity and catalyst stability was determined.
