<p>A process for the preparation of a catalyst useful for conducting carbon monoxide hydrogenation reactions, particularly Fischer-Tropsch reactions; the catalyst compositions, use of the catalyst compositions for conducting such reactions, and the products of these reactions. The steps of the process for producing the catalyst comprise mixing together in solution (a) a compound, or salt of a Group VIII metal, e.g., Co(NO3)2; (b) a compound, or salt of magnesium, e.g., Mg(NO3)2; (c) a compound, salt, or powdered oxide of a Group IVB metal, e.g., zirconia; (d) a refractory inorganic oxide, e.g., kieselguhr; and (e) an ammonium or alkali metal salt precipitating agent, e.g, Na2CO3, to produce a precipitated solids mass, or catalyst precursor, and then reducing the precipitated solids mass, or catalyst precursor, to form a catalyst, e.g., (100Co:6 MgO:10 ZrO2:200 kieselguhr). The precipitated solids mass, or catalyst precursor, is shaped and brought to a critical level of moisture, and reduced. A catalyst formed from the precursor in this manner has greater activity, and selectivity in the production of high melting waxes in conducting Fischer-Tropsch reactions, and gas make is lower, than in the use of catalysts made conventionally, i.e., from precursors of similar composition at differing moisture levels.</p> |
