The deactivation of commercial catalyst for water gas shift reaction (WGSR) has been studied through activity evaluation, temperature program med technique, XRD, porosity and sulfur content measurements. It is found that the deactivation of a long-run catalyst is the results of sintering, formation of the inactive phases of MoS₂, CoS₂, CoSO₄ and MgAl₂O₄, and irreversible conversion of the active sulfur component into inactive ones. Temperature and steam advance the deactivation.
