STABILIZED CATALYST COMPRISING ALUMINA

摘要

The stabilized catalyst comprises a stable support which comprises alumina in combination with at least two further metal oxides, of which two further metal oxides at least one first metal oxide, is thermodynamically stable at a hydrogen partial pressure of 1 bar and a water partial pressure of 10-10 bar at a temperature of 700°C, and of which two further metal oxides at least one further metal oxide is an oxide of a metal taken from a group comprising lanthanoid elements and alkaline earth metals and said catalyst further having an active phase comprising nickel and a Group VIB element, with the associated benefit of such a catalyst having a high activity and stability at elevated temperatures.
