Question
How can the production of dihydrogen, obtained from coal gasification, be increased?
Open in App
Solution
Coal gasification method is used for the production of dihydrogen gas.
To increase the yield of dihydrogen, CO is reacted with steam in presence of iron chromate catalyst. This is water gas shift reaction. Carbon dioxide is scrubbed with solution of sodium arsenite.
CO(g)+H2O(g)→CO2(g)+H2(g)
