摘要：

Alkali nitrate promoted Raney Ru catalysts were prepared by hydrogenolysis of alkali nitrates (CsNO3, RbNO3, KNO3, and NaNO3) over Raney Ru. These catalysts were even more active in ammonia synthesis than Raney Ru promoted with metallic potassium. The promotion behaviour was different from that for the supported Ru catalysts, where metallic potassium was more effective than CsNO3. Per-weight activity of CsNO3 promoted Raney Ru was higher than that for any catalysts so far reported in ammonia synthesis under 80 kPa and at 573 K. © 1990 J.C. Baltzer A.G.
