CO Shift Catalysts

New type of sulfur-tolerant water gas shift catalyst XB-2 was prepared with the impregnation method of Co-Mo active composition on the support of magnesium-alumina spinel. The catalyst activity was investigated in a fixed bed device with original-sized catalyst granules. The catalyst was characterized with XRD、BET and SEM techniques. The results of life-time test in a period of 300 hours showed that the new type of catalyst XB-2 had higher activity and resistance to hydration in comparison with the commercial catalyst under high pressure and at high steam-to-gas ratio condition. Moreover the catalyst XB-2 was found to have stable construction and high mechanical strength.
