In general, the reduction of Fe 2 O 3, called hematite, does not occur directly to metallic iron, the reduction temperature is lower than 570 °C, reduction to Fe occurs stepwise from Fe 2 O 3 to Fe 3 O 4, called magnetite, and continues to intermediate oxide, wüstite Fe (1−x) O, is not stable at temperatures lower than 570 °C. At reduction temperatures higher than 570 °C ...
iron oxidetitanium oxide first and found that Fe 2 O 3TiO 2 alysts exhibited high activity and selectivity over a temperature range of 350 oC450 C. The deep investigation found that the activity was enhanced with increase in the content of SO 4 2− in the alyst [20]. Liu et al. [21] reported a novel iron titanate alyst which has ex
