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…

Effects of small MoO3 additions on the properties of nickel catalysts for the…
Abstract. Ni/Al2O3 catalyst modified by small amounts of Mo show unusual properties in the steam reforming of hydrocarbons. There are no data about the effect of small amounts of molybdenum on reduction of the Ni-Mo supported catalysts. The properties of these very complex systems depend on the conditions of successive preparation stages (calcination, reduction) or the process conditions. A se…

Abstract. Addition of molybdenum to nickel catalysts has a favourable effect on their properties in the steam reforming of hydrocarbons. Some attempts were made to explain the mechanism of promoter action by determining the properties of such catalysts in hydrogenolysis and cracking reactions.With small amounts of promoter (≤0.5 wt.%) advantageneous changes in selectivity of steam reforming …

Methane decomposition over Ni–MgO–Al2O3 catalysts
Abstract. Studies of methane decomposition were performed over nickel alumina catalysts modified with magnesia. The catalysts were obtained by the co-precipitation method. The properties of catalysts were investigated by the temperature programmed reduction (TPR) and hydrogen desorption (TPD) methods. Methane decomposition was studied by the thermogravimetric and transient temperature progr…
