    摘要: A process for the preparation of a catalyst useful for conducting carbon monoxide conversion reactions, especially a Fischer-Tropsch catalyst, use of the catalyst for conducting such reactions, especially Fischer-Tropsch reactions, and the composition produced by said process. In the preparation of the catalyst, a solution of a polyol is employed to impregnate and disperse a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel, or in a preferred embodiment both a compound or salt of rhenium and a compound or salt of a catalytic metal, or metals, e.g., copper or an Iron Group metal such as iron, cobalt, or nickel onto a refractory inorganic oxide support, e.g., titania. The rhenium, when present only in small amount permits full and complete reduction of the catalytic metal, or metals, dispersed by the polyol. Higher catalyst activities with lower rhenium loadings are thus achieved than in previous preparations where higher concentrations of rhenium were required to both effectively disperse, and reduce the catalytic metal, or metals, during the preparation. Surprisingly, as little as about {fraction (1/10)} of the rhenium is required to accomplish the reduction promotion where the dispersion is effected with the polyol.

    摘要: A novel ruthenium catalyst, notably a ruthenium-titania catalyst, is disclosed to which is added sufficient rhenium to obtain, at corresponding process conditions, improved activity maintenance in the production of hydrocarbons via carbon monoxide-hydrogen synthesis reactions vis-a-vis a catalyst composition otherwise similar except that it does not contain rhenium. High quality middle distillate fuels, characterized generally as admixtures of linear paraffins and olefins, are formed in a process wherein a feed mixture of carbon monoxide and hydrogen are contacted at reaction conditions over such catalyst.

    摘要: A process for the synthesis of catalysts by pre-forming a porous refractory inorganic oxide support, or carrier from a coarse particulate solid, preferably an alumina extrudate, contacting said preformed support with an acid solution, and then treating, contacting and neutralizing said preformed acid treated support with a base prior to the impregnation of said neutralized support with a metal, or metals, hydrogenation-dehyrdogenation component. The preformed solid support ranges at least about 1/32 inch diameter, and preferably at least about 1/16 inch diameter, and larger.
