    • 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 carbohydrate, or sugar, notably a monosaccharide or disaccharide, particularly sucrose, 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 carbohydrate. 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 1/10 of the rhenium is required to accomplish the reduction promotion where the dispersion is effected with the carbohydrate.
    • 用于制备用于进行一氧化碳转化反应的催化剂,特别是费 - 托催化剂的方法,所述催化剂用于进行这种反应,特别是费 - 托反应,以及由所述方法制备的组合物。 在催化剂的制备中,使用碳水化合物或糖,特别是单糖或二糖,特别是蔗糖的溶液来浸渍和分散催化金属或金属例如铜或铁组的化合物或盐 金属如铁,钴或镍,或在优选的实施方案中,铼的化合物或盐和催化金属的化合物或盐,或金属,例如铜或铁族金属如铁,钴或 镍,添加到耐火无机氧化物载体上,例如二氧化钛。 铼当仅存在少量时,允许完全和完全地还原由碳水化合物分散的催化金属或金属。 因此实现了较低的铼负载量的较高催化剂活性,而不需要较高浓度的铼在制备期间有效地分散和还原催化金属或金属的以前制备。 令人惊奇的是,只要大约+ E,需要铼的1/10 + EE即可完成使用碳水化合物进行分散的还原促进。

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.
