उत्तर
- Step I - Production of water gas -
\[\ce{C + H2O->[1000°C]\underset{\text{water gas}}{[CO + H2]} - \triangle}\] - Step II - Reduction of steam to hydrogen by carbon monoxide
\[\ce{CO + H2 + H2O->[450°C][Fe2O3] CO2 + 2H2 [g]}\] - Step III - Removal of unreacted carbon dioxide and carbon monoxidefrom the above mixture
KOH + CO2 → K2CO3 + H2O
CuCl + CO + 2H2O → CuCl.CO.2H2O
