The production of dihydrogen in Coal gasification can be increased by reacting CO(g) present in syngas with steam in the presence of iron chromate catalyst.
{tex}CO(g) + {H_2}O(g)\xrightarrow[{673k}]{\begin{subarray}{l} FeCr{O_4} \\ (catalyst) \end{subarray} }C{O_2}(g) + {H_2}(g){/tex}
With the removal of CO2 the reaction shifts in the forward direction and thus the production of dihydrogen will be increased. This is called water-gas shift reaction. Carbon dioxide is removed by scrubbing with sodium arsenite solution
