Because in medium-temperature shift catalysts, iron chlorides exhibit higher activity mainly in the form of Fe3O4.

Water vapor is added during the reduction of medium-temperature catalysts to prevent Fe3O4 from being further reduced to metallic iron and thus losing its activity

The catalyst is provided in the form of -Fe2O3, and it must be reduced to Fe3O4 to become active.
In medium-temperature shift catalysts, iron chlorides exhibit higher activity primarily in the form of Fe3O4
The catalyst is in an oxidized state and needs to be reduced to become active
Reduce iron oxide to ferric tetraoxide with conversion activity
The catalyst is provided in the form of -Fe2O3, and it must be reduced to Fe3O4 to become active.
Since the catalyst loses its activity after being oxidized, it needs to be reduced.
Because in medium-temperature shift catalysts, iron chlorides exhibit higher activity mainly in the form of Fe3O4.
