<p>The present invention relates to a method of preparing a catalyst support or a supported metal catalyst, the method comprising: (a) admixing a porous refractory oxide with a water soluble zirconium precursor in an alkaline solution, and if a supported metal catalyst is prepared, with a precursor of the metal, yielding a slurry, (b) drying the slurry, and (c) calcining; thus yielding a catalyst support or supported metal catalyst having an increased hydrothermal strength. The invention further relates to a method of preparing a catalyst body, the method comprising: (a) admixing a porous refractory oxide with a water soluble zirconium precursor in an alkaline solution, and if a supported metal catalyst is prepared, with a precursor of the metal or the metal itself, yielding a slurry, (b) coating metal with the slurry, (c) drying the coating, and (d) calcining; thus yielding a catalyst body comprising a catalyst support or supported metal catalyst having an increased hydrothermal strength In a preferred embodiment, the zirconium containing compound comprises zirconium carbonate in an ammonium solution. The improved hydrothermal strength is particularly suitable for slurry-type Fischer-Tropsch reactors.</p> |
