Answer- 

The process of producing syngas from coal is known as 'coal gasification'

C(s)+H_{2}(g)\rightarrow CO(g)+H_{2}(g)

The production of dihydrogen can be increased by reacting carbon monoxide of syngas mixture with the steam in the presence of iron chromate as a catalyst. This is called 'water gas shift reaction'. carbon dioxide can be removed by scrubbing with a sodium solution.

CO(g)+H_{2}O(g)\rightarrow CO_{2}(g)+H_{2}(g)
