Question:

How can the production of dihydrogen, obtained from ‘coal gasification’, be increased?

Answer:

Dihydrogenis produced by coal gasification method as:

                                          1270K

C(s)      +      H2O(g)      →     CO(g)    +   H2(g)        

(Coal)

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. Carbon dioxide is removed by scrubbing it with a solution of sodium arsenite.
