Process for preparing iron-chromium catalyst with platinum promoter, and catalyst consisting of iron-chromium with platinum promoter

The invention relates to catalysts of iron and chromium with a platinum promoter for use in water-gas shift reactions, both at low temperatures (LTS) and at high temperatures (HTS). Their characteristics of higher activity due to the addition of Pt compared to the conventional catalysts make them superior to the commercial catalysts in the same operating conditions. Because precursors of the active phase (Fe3O4) are obtained in greater quantity per unit area, it was possible to prepare catalysts that are more promising with a smaller surface area. 本发明涉及在低温(LTS)水煤气变换反应和高温(HTS)水煤气变换反应都可用的具有铂助催化剂的铁-铬催化剂。与常规催化剂相比，由于添加Pt而具有较高活性的特征使所述催化剂在相同操作条件下优于市售催化剂。由于单位面积获得的活性相(FeO)的前体更多，所以可以制备具有更小表面积的催化剂。
