  • Process for preparing an iron-chromium catalyst with a platinum promoter, and catalyst consisting of iron chromium with a platinum promoter
    Patent number: 11241683
    Abstract: The present 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.
    Type: Grant
