The sulfurization and desulfurization of water gas shift catalyst CoMoK/Al2O3 have been investigated by TPS and TPDS techniques,using H2S and CS2 as sulfurizing agents.Only H2S consumption and H2O formation were found when the catalyst was sulfurized with H2S/H2.When CS2/H2 was used as sulfurizing agent,CO2 was formed at first,then CH4,H2O and H2S as shown by TPS curves.Carbon deposition on the catalyst during the sulfurization with CS2/H2 caused lowering of the catalytic activity,but the deposifed carbon could be reduced in the run of WGS reaction.The results of TPDS indicated that N2 does not act in desulfurization and H2 or CO also does not give an obvious effect on the desulfurization.However,H2O shows a strong desulfurizing effect.Oxygen caused a permanent loss of the activity in some part of the catalyst.XPS results showed that Mo4+ has been changed to Mo5+ and Mo6+ in desulfurized catalyst,decreasing its activity.
