In which of the following conversion iron chromate catalyst is used.
C + H2O → CO + H2
CO + H2O → CO2 + H2
CO + H2 → CH3OH
CO + 3H2 → CH4 + H2O
The product of Hydrogen can be increased by reacting CO of syngas mixture with steam in the presence of iron Chromate as Catalyst.
This is called watergas shift reaction.
