Oxidation–reduction of Ni/Al2O3 steam reforming catalysts promoted with Mo

Abstract. Model Ni/Al2O3 catalysts promoted with different amounts of molybdenum were examined in order to explain a strong increase of the resistance to coking in the steam reforming of hydrocarbons. The properties of catalysts were investigated after various treatment conditions in the water/hydrogen mixtures by means of XRD, XPS, temperature-programmed and gravimetric methods. The studies e…
