प्रश्न
How can the production of dihydrogen, obtained from ‘coal gasification’, be increased?
Advertisements
उत्तर
The production of dihydrogen in coal gasification can be increased by reacting CO(y) present in syngas with steam in the presence of iron chromate catalysts.
\[\ce{CO(g) + H2O(g) ->[FecrO4(catalyst)][673 K] CO2 (g) + H2(g)}\]
With the removal of CO2 the reaction shifts in the forward direction and thus, the production of dihydrogen will be increased.
