ABSTRACT The invention provides a process for the preparation of a transition metal-silicate catalyst in which an in- soluble, basic compound of a transition metal having an atomic number between 26 and 30 (in particular nickel which has an atomic number of 28) is rapidly pre- cipitated with an alkaline precipitation agent from an aqueous solution of such a metal salt, as a suspension, which precipitate is allowed to mature for a longer period in a suspended form, and, after the transition metal ions have been practically completely precipi- tated, soluble silicate is added to the suspension, after which the solids are separated from the liquid, optionally washed, dried and reduced.
