ABSTRACT:
The present invention relates to a Catalyst comprising a, preferably oxidic, core material, a shell of zinc oxide around said core material, and a catalytically active material in or on the shell, based on one or more of the metals cobalt, iron, ruthenium and/or nickel, preferably a Fischer-Tropsch catalyst, to the preparation of such a catalyst and the use thereof in GTL processes.
