Abstract: The deactivation of two commerciaI Co－Mo/MgO－Al2O3 type WGS catalyst has been studied by XRD, SEM, Raman spectroscopy,and ICP techniques. The results showed that the deactivation is mainIy due to the formation of MoS2 and MgAl2O4. Roasting at higher temperatures makes catalysts crystalizable.The strticture of catalysts direetly depends on the method of their preparation.Catalysts of strip shape powderized more easily. Process of regeneration lowers the stability of catalysts,The second-important reason of deactivation of catalysts is the preseence of inorganic impurities.
Key words: Co－Mo/MgO－Al2O3, water-gas shift catalyst, deactivation
