Abstract: | The effect of aluminum content on the properties of lanthana-supported nickel catalysts was evaluated in this work, in order do find new catalysts for water gas shift reaction (WGSR). It was noted that small amounts of aluminum increased the specific surface and the activity and thus is benefic to the catalyst. However, high amounts of aluminum causes a decrease on both properties and this was assigned to a strong interaction between nickel and aluminum, which stabilizes the Ni2+ species on the surface and makes the production of the active phase (metallic nickel) more difficult. |
