PROCESS FOR THE PREPARATION OF HIGH ACTIVITY CARBON MONOXIDE HYDROGENATION CATALYSTS; THE CATALYST COMPOSITIONS, USE OF THE CATALYSTS FOR CONDUCTING SUCH REACTIONS, AND THE PRODUCTS OF SUCH REACTIONS
A process for the preparation of a catalyst for carbon monoxide hydrogenationparticularly Fischer-Tropsch reactions;the catalyst compositions, use of the catalyst compositions for conductingsuch reactions. The process for producing the catalystcomprises impregnating a powder, or particulate refractory inorganic oxidesolids, preferably silica, with a) a soluble compound orsalt of a catalytic metal of the Iron Group, preferably cobalt, and b) asoluble compound of a Group VIII noble metal, preferably platinum,suitably by sequential contact of the solids with a solution of (a) and asolution of (b), by sequential contact of the solids with asolution of (b) and a solution of (a), or by contact with a solution whichcontains both (a) and (b). The metals impregnated solids, orparticulate solids precursor material, after impregnation with the Group VIIInoble metal, is washed with a hydrocarbyl ammoniumhydroxide or ammonium hydroxide solution, the material shaped, dried andcalcined, and the metals components thereof thereafterreduced. The catalyst thus formed, quite surprisingly, is more active andselective in conducting a carbon monoxide hydrogenationreaction to produce hydrocarbon waxes, with lower gas make.
