A process for the preparation of a catalyst for carbon monoxide hydrogenation particularly Fischer-Tropsch reactions; the catalyst compositions, use of the catalyst compositions for conducting such reactions. The process for producing the catalyst comprises impregnating a powder, or particulate refractory inorganic oxide solids, preferably silica, with a) a soluble compound or salt of a catalytic metal of the Iron Group, preferably cobalt, and b) a soluble compound of a Group VIII noble metal, preferably platinum, suitably by sequential contact of the solids with a solution of (a) and a solution of (b), by sequential contact of the solids with a solution of (b) and a solution of (a), or by contact with a solution which contains both (a) and (b). The metals impregnated solids, or particulate solids precursor material, after impregnation with the Group VIII noble metal, is washed with a hydrocarbyl ammonium hydroxide or ammonium hydroxide solution, the material shaped, dried and calcined, and the metals components thereof thereafter reduced. The catalyst thus formed, quite surprisingly, is more active and selective in conducting a carbon monoxide hydrogenation reaction to produce hydrocarbon waxes, with lower gas make.
