Question
In the industrial method of preparation of hydrogen by the Bosch process give the balanced equations for the first two main steps in the production of hydrogen.
Solution
Bosch process for industrial production of hydrogen:
Step [I] : Preparation of water gas [CO + H2] by passing steam over white hot coke.
\[\ce{C +\underset{\text{Steam}}{H2O} ->[1000°C]\underset{\text{[Water gas]}}{[CO + H2]} - \triangle}\]
Step [II] : Reduction of steam to hydrogen by carbon monoxide.
\[\ce{\underset{\text{[Water gas]}}{CO + H2} +\underset{\text{[Excess steam]}}{H2O}->[450°C][Fe2O3] CO2 + 2H2 +\triangle}\]
