9.4 How can the production of dihydrogen, obtained from ‘coal gasification’, be increased?
Answer-
The process of producing syngas from coal is known as 'coal gasification'
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.
