Effect of Catalysts and Additive Containing Li on the Reduction of Hematite by Carbon Monoxide

The effect of catalysts and additive containing Li on reduction of Fe₂O₃ by carbon monoxide has been studied by experimental methods. It is found that both of the catalysts and the additive have catalytic effect, moreover, the catalyst containing Li is more affective. X-ray diffraction showed that the main phases in catalyst containing Li are α-Fe and FeO, therefore, it is considered that α-Fe and FeO can also promote the reduction of Fe₂O₃ by carbon monoxide
