This CO shift catalyst, which reforms carbon monoxide (CO) present in a gas, comprises the following: an active component containing a primary component, namely either molybdenum (Mo) or iron (Fe), and a secondary component, namely either nickel (Ni) or ruthenium (Ru); a promoter component containing either calcium (Ca), potassium (K), sodium (Na), phosphorus (P), or magnesium (Mg); and a support that supports the active component and the promoter component. Said support consists of one or more of the following: an oxide of titanium (Ti); an oxide of zirconium (Zr); and an oxide of cerium (Ce). L'invention concerne un catalyseur de conversion de CO, qui reforme le monoxyde de carbone (CO) présent dans un gaz, qui comprend ce qui suit: un composant actif contenant un composant primaire, à savoir du molybdène (Mo) ou du fer (Fe), et un composant secondaire, à savoir du nickel (Ni) ou du ruthénium (Ru); un composant promoteur contenant du calcium (Ca), du potassium (K), du sodium (Na), du phosphore (P), ou du magnésium (Mg); et un support qui supporte le composant actif et le composant promoteur. Ledit support est constitué d'un ou de plusieurs des suivants: un oxyde de titane (Ti); un oxyde de zirconium (Zr); et un oxyde de cérium (Ce).
