| Abstract: | The effects of preparation variables including leaching methods, temperature, alkali concentration, alloy composition on the structure and the F-T synthesis activity of Raney Fe were discussed in detail The optimized process for the Raney Fe preparation are obtained, which was using the regular leaching method, under higher leaching temperature, and medium concentration of alkali, and the Fe-Al with Al/Fe ratio of 4 The activity of the catalyst was up to that of precipitated Fe in slurry F-T synthesis |
