在350~400℃的间歇式反应装置上，考察了Khafji原油常压渣油加氢脱硫剂在氧化铝担载的钴钼催化剂上的反应。但是，水煤气变换反应产生的过量水和二氧化碳都抑制了脱硫。考察了一系列钼含量为10wt%、钴钼比不同的钴钼催化剂的脱硫活性。当Co/Mo比为0.5(原子/原子)时，钴-钼体系的活性在所用条件下达到最大。似乎有理由认为，可用于一氧化碳加水加氢脱硫的催化剂不仅负责促进水-气变换反应，而且还负责促进随后的加氢脱硫。
Hydrodesulfurization of atmospheric residual oil of Khafji crude with carbon monoxidewater mixtures was examined on alumina-supported cobalt-molybdenum catalysts using a batchautoclave at 350-400°C. In this reaction system, the water-gas shift and desulfurization reactions took place concurrently. However, both the excess water and the carbon dioxide produced by the water-gas shift reaction inhibited the desulfurization. A series of cobalt-molybdenum catalysts with 10wt% molybdena and with varying ratios of Co/Mo was examined for desulfurization activity. With the Co/Mo ratio of _??_0.5 (atom/atom), the cobalt-molybdenum system reached its maximum activity under the conditions used. It seems reasonable to suppose that the catalyst, available for hydrodesulfurization using carbon monoxide plus water, is responsible not only for promoting the water-gas shift reaction but also for promoting subsequent hydrodesulfurization.
