उत्तर
Srep I:
Steam is passed over white hot coke at 1000°C
\[\ce{\underset{\text{[Coke]}}{C} + \underset{\text{Steam}}{H2O}->[1000°C]\underset{\text{Water gas}}{[CO + H2]} - \triangle}\]
Water gas is obtained.
Step II:
Reduction of steam to hydrogen - by CO
\[\ce{\underset{\text{Water Gas}}{[CO + H2]} +\underset{\text{[Excess Steam]}}{H2O} ->[450°C][Fe2O3] CO2 + 2H2 + \triangle}\]
