QDB-06 is a new C2 sulfur-resistant shift catalyst suitable for use in isothermal shift reactors. The catalyst contains special anti-hydration and low-temperature activity additives. When used under low temperature, high pressure, high space velocity and high water/gas conditions, it has good low-temperature activity and anti-hydration performance, and can meet the requirements of isothermal shift process for catalyst performance.
