A chromium-free catalyst for use in a fluidized bed reactor is described. The catalyst comprises 45-70 wt % FeO, 5-15 wt % CuO, 20-35 wt % AlO, 10-20 wt % ZnO, and 1-15 wt % KCO. The catalyst has a Davison Index (DI %) of less than or equal to 15. A method for converting carbon monoxide (CO) into carbon-dioxide (CO) using the catalyst is described. The method includes introducing HO and CO into a fluidized bed reactor having an operating temperature between about 375° C. and about 450° C. and comprising the chromium free catalyst. The CO conversion is at least 60%.
