Which of the following reaction increase production of dihydrogen from synthesis gas ?

Options

A. `CH_(4)(g) +H_(2)O(g) underset(Ni)overset(1270K)toCO(g) + 3H_(3)(g)`
B. `C(s) +H_(2)O(g) overset(1270K)to CO(g) +H_(2)(g)`
C. `CO(g) + H_(2)O(g) underset("Catalyst")overset(673K)to CO_(2)(g) +H_(2)(g)`
D. `C_(2)H_(6) +2H_(2)O underset(Ni)overset(1270K)to2CO + 5H_(2)`

Answer

C

Explanation

The process of producing syn gas or suynthesis gas for coal is called 'coal' gasification .

The production of hydrogen can he increased by reacting carbon monoxoide of the syn gas with steam in the presence of iron chromate as a catalyst at 673K.

`CO_(2)` is removed by scrubbing with a solution of sodium arsenite.
