Abstract Taking advantages of various characterizing techniques and comparative data between the activated and deactivated Co-Mo-K/Al 2O 3 sulfide catalysts for WGSR obtained some results. It was found that in the deactivated sample some K and S ingrated from interier to exterior and carried away by the gas stream, Al 2O 3 was changed from ��-Al 2O 3 to (Al 2O 3). 10R some more stable form of Co and Mo components were formed by the action of higher steam partial pressure resulting in the loss of reactivity seriously. Besides, Fe, Ni, and Co trapped by the feed gas from the pipe lines and vessels deposited on the surface the covering of the active sites, thus made the situation worse.
