摘要: 通过还原试验,研究了LiCl与含Li催化剂对Fe2O3的CO还原作用,发现不论是LiCl还是含Li催化剂均对Fe2O3的CO还原有催化作用,其中以含Li催化剂对Fe2O3的CO还原催化效果最好.用X-rar鉴定含Li催化剂的物相,主要以α-Fe和FeO相存在,说明了含Li催化剂中的α-Fe亦对Fe2O3的CO还原有催化作用.Abstract: 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
