Process for the preparation of one or more metal or metal compounds containing catalysts or catalyst precursors wherein a complex cyanide of the general formula M1M2(CN)p-x(Y)x wherein M1 represents a cationic moiety comprising one or more metal ions, NH4<+> and/or a quaternary ammonium ion, M2 forms part of the anionic moiety and represents one or more polyvalent metals, CN represents a cyanide moiety as defined hereinbefore, Y represents one or more ligands, p is a number ranging from 2 - 8, x is a number ranging from 0 - 4 and p/x is at least 1 when x &rang& 0, present on a carrier is subjected to a decomposition treatment under oxidative conditions. The catalysts thus obtained can be suitably applied for instance in the preparation of hydrocarbons and/or oxygenates from carbon monoxide and hydrogen and in the hydrodesulphurisation of hydrocarbonaceous materials. <IMAGE> |
