How can the production of dihydrogen from 'coal gasification' be increased? |
|
Answer» Solution :In coal gasification reaction,steam vapours are passed through coke to form MIXTURE of CO and `H_(2)` also called syn gas. `C(s)+H_(2)O(g) to ubrace(CO(g)+H_(2)(g))_("syn gas")` The production of dihydrogen can be INCREASED by reacting `CO(g)` present in syn gas with steam in hte presence of IRON chromate catalyst With the removal of `CO(g) or CO_(2)(g)`, the reaction shifts in the forward direction direction. This is KNOWN as water gas SHIFT reaction. As a result, the production of dihydrogen will increase. `CO(g)+H_(2)O(g) underset(673K) overset(FeCrO_(4)("catakyst"))to CO_(2)(g)+H_(2)(g)` |
