The deactivation of two commercial 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 mainly due to the formation of MoS2 and MgAl2O4. Roasting athigher 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.
