Zusammenfassung:	In a broad form the present disclosure relates to a stabilized catalyst support comprising in oxide form; aluminum, zirconium, and one or more lanthanoid elements taken from the lanthanoid group of the periodic system characterized in that at least a part of the aluminum is present as transition alumina such as χ, , γ, δ, and -alumina, characterized in the concentration of zirconium being at least 1.5 wt %, 5 wt % or 10 wt %, the concentration of lanthanoid being at least 0.5 wt %, 1.0 wt %, 2 wt % or 4 wt % and the combined concentration of zirconium and lanthanoid being at least 4 wt %, 7 wt % or 10 wt %, with the associated benefit of a support comprising transition alumina being a high surface area due to the small crystallites typical for transition alumina, and the benefit of the combined presence of oxides of zirconium and lanthanoid in the stated amounts being that at these levels these oxides stabilize the structure of the transition alumina.
