摘要：A process for the preparation of a catalyst useful for conducting carbonmonoxide hydrogenation reactions, especially a Fischer- Tropsch catalyst, use of thecatalyst for conducting such reactions, especially Fischer-Tropsch reactions, and thecomposition produced by said process. In the preparation of the catalyst, a solution of amulti- functional carboxylic acid having from about 3 to 6 total carbon atoms, preferablyabout 4 to 5 total carbon atoms, is employed to impregnate and disperse a compound orsalt of rhenium and a compound or salt of a catalytic metal, or metals, e.g., copper or anIron Group metal such as iron, cobalt, or nickel onto a refractory inorganic oxide support,e.g., titania. The rhenium, which need be present only in small amount permits full andcomplete reduction of the catalytic metal, or metals, dispersed by the acid. Highercatalyst activities with lower rhenium loadings are thus achieved than in previouspreparations where higher concentrations of rhenium were required to both effectivelydisperse, and reduce the catalytic metal, or metals, during the preparation. Surprisingly,as little as about 1/10 of the rhenium is required to accomplish the reduction promotionwhere the dispersion is effected with the acid.
