QDB-03 is a new type of CO sulfur-resistant shift catalyst with magnesium aluminum spinel as carrier, prepared by special method and containing multi-component composite additives. It is suitable for the process of producing shift process gas and city gas from coal or residual oil as raw materials, especially for the process of producing hydrogen, ammonia synthesis gas, city gas and carbonyl synthesis gas from coal or residual oil as raw materials by high-medium pressure gasification.
QDB-03 catalyst does not contain alkali metal additives, so the activation temperature is higher and the low-temperature activity is worse than QDB-04. However, due to the high content of active components, the special preparation method and the active stability additives, the outstanding advantage of QDB-03 catalyst is that it has good activity and structural stability when used under high pressure, high space velocity and high water/gas conditions.
