Fremgangsmåde til fremstilling af siliciumdioxid-bårne cobalt-katalysatorer samt anvendelse deraf |
摘要 |
The invention relates to catalysts comprising cobalt supported on a solid silica support and, in particular, to a method for manufacturing such catalysts. The catalysts may be prepared by slurrying a silica powder or impregnating a silica particle with a solution of a cobalt compound, cobalt amine carbonate, and aging the resulting slurry or solid at elevated temperature; the cobalt amine carbonate is decomposed and precipitated as basic cobalt carbonate onto the silica support. Preferably, the catalysts have a cobalt surface area in the range of 25 to >100 m2 per gram total cobalt. The catalyst may be used in hydrogenation reactions, Fischer-Tropsch reactions and oxidation reactions. |
