QDB-05 catalyst is developed on the basis of QDB-04 catalyst. This catalyst is added with special additives and is suitable for use in high CO feed gas low water/gas shift process. It has the function of inhibiting methanation side reactions. When performing high CO concentration feed gas shift reaction, it can exert excellent catalyst activity and inhibit the occurrence of methanation side reactions.
