  • Chromium-free Fe-based catalyst for CO high-temperature-shift reaction and its preparation
    Patent number: 6569804
    Abstract: A chromium-free Fe-based catalyst for CO HTS reaction, comprising about 65 to about 90% by weight of Ferriate oxides; about 1 to about 10% by weight of Al, Fe, Si-mixed oxides (Al:Fe:Si=6:2:1) or aluminum-silicon-sol (Al:Si=8:2); about 0.5 to about 2.0% by weight of vanadium oxides; about 0.5 to about 3.0% by weight of magnesium oxides; about 0.5 to about 3.0% by weight of nickel oxides and about 0.1 to about 0.6% by weight of potassium oxide, based on the total weight of the catalyst. There is also provided a method for producing the catalyst.
