    • A process for the conversion of carbon monoxide in synthesis gas mixtures to hydrogen and CO.sub.2 utilizes a catalyst which is active in the presence of sulfur compounds, and which comprises the oxides or sulfides of cobalt and molybdenum, supported on a shaped, relatively high surface area aluminous carrier. The carrier is stabilized by admixture with one or more rare earth metal oxides while the alumina is in the hydrated condition. The mixture of hydrated alumina and rare earth metal oxide is formed into a desired shape and calcined to convert the hydrated alumina to the oxide. Thereafter, the calcined, high surface area alumina is impregnated with the desired salts of cobalt and molybdenum and the impregnated catalyst is thereafter calcined and placed into service. The stabilized catalyst exhibits good activity at relatively low temperatures with synthesis gas mixtures containing sulfur compounds and retains its surface area and the aluminous carrier is not converted over to the alpha phase.
    • 将合成气混合物中的一氧化碳转化为氢气和二氧化碳的方法利用在硫化合物存在下活性的催化剂,其包含钴和钼的氧化物或硫化物,负载在成形较高的表面积 铝载体。 载体通过与一种或多种稀土金属氧化物的混合而稳定,而氧化铝处于水合状态。 将水合氧化铝和稀土金属氧化物的混合物形成所需形状并煅烧以将水合氧化铝转化为氧化物。 此后,煅烧的高表面积氧化铝用所需的钴和钼盐浸渍,然后将浸渍的催化剂煅烧并投入使用。 在含有硫化合物的合成气混合物中,稳定的催化剂在相对低的温度下表现出良好的活性并保持其表面积,并且铝载体不转化为α相。
