Abstract: Two types of Co-Mo spherical sulfur-resistant water-gas shift catalysts, B302Q and EB-4, have been studied in their microstructure by XRF, XRD and XPS methods.The results showed that the fcrmation of CoAl2O4 and CoMoO4 phases during the calcination leads in the deactivation of the catalyst B302Q.

Key words: CO-Mo/Al2O3, water-gas shift catalyst, microstructure
