Popis: | The use of commercial magnetite-type iron ore and of ferriferous quartzite type ore as catalysts for low-temperature Fischer–Tropsch synthesis is described. According to the results of chemical analysis, the ores mainly contained iron magnetite, carbon, and also baddeleyite (ZrO2 + HfO2) and hatchettolite (Ta2O5 + Nb2O5 + U3O8). The ore samples with the highest iron content (48–59%) and the lowest sulfur content (0.1% and less) showed activity in the Fischer–Tropsch synthesis without additional modification in the commercial form. The yield of liquid products in the synthesis performed on the most active samples of ore catalysts exceeded 100 g m–3 at the СО conversion of approximately 60%. The ore activity in the Fischer–Tropsch synthesis may be associated with the fact that these natural mineral formations contain oxides exerting a promoting effect when using the ores as catalysts. |
