Metal powders such as Fe, Co, Ni, Fe-Co, and Fe-Ni prepared by reducing metal iodides or bromides with potassium metal in refluxing THF were used as catalysts for Fischer-Tropsch syntheses. These metal powders contained very small particles and have BET surface areas (28-36 m/sup 2//g). The metal powder catalysts, such as Fe and Fe-Co (80:20), gave 1-butene with more than 35 wt% selectivity at a rather high CO conversion of over 10 wt% at 533-553 K, while products on the Co catalyst obeyed conventional Schulz-Flory type distribution. The Ni catalyst showed little activity. Effects of reaction variables (temperature, H/sub 2//CO feed gas ratio, and composition of Fe-Co) were investigated.
