Process for the preparation of extrudates suitable for use in the manufacture of catalysts or catalyst carriers, especially Fischer-Tropsch catalysts, comprising mulling a mixture of finely divided silica, a water soluble compound derived from a metal selected from group IVb of the Periodic Table and water, the mixture having a solids content of 20 to 50% by weight, and extruding the mixture. After drying and/or calcining, the extrudates may be impregnated with one or more suitable metal compounds, optionally followed by drying, calcination and/or activation, and used as a catalyst. |
