Question

how can the production of dihydrogen obtained from coal gasification be increased​

Answer 1

Answer:

The yield of dihydrogen (obtained from coal gasification) can be increased by reacting carbon monoxide (formed during the reaction) with steam in the presence of iron chromate as a catalyst. This reaction is called the water-gas shift reaction.

Answer 2

Answer:

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.
