A process for the preparation of an extruded silica-based catalyst or catalyst precursor comprising a catalytically active component selected from the elements in Group VII B or Group VIII of the Periodic Table and a promoter selected from elements in Group IVB of the Periodic Table, which process comprises mulling a mixture comprising silica, a solvent and, optionally, one or both of a catalytically active component source and a promoter source, which mixture has a solids content of from 20 to 60%wt; extruding the mulled mixture; and depositing on the resulting extrudates a catalytically active component source and a promoter source, the deposition of either or both the catalytically active component source and the promoter source on the extrudates being optional in cases in which the mixture comprises a source for either or both the said component or the promoter; with the proviso that if the mixture comprises a promoter source but does not comprise a catalytically active component source, the promoter source is insoluble in the solvent. The catalytically active component is preferably cobalt. The promoter is most preferably zirconium. The product of the process is of particular use as a catalyst in the preparation of hydrocarbons from a mixture of carbon monoxide and hydrogen.
