Expert Answer:

At 1270 K and in the presence of Nickel,

CH4 (g) + H2O(g)  CO(g) + 3 H2(g)


This mixture of CO and H2 is called water gas or syn gas.

The production of dihydrogen can be increased by reacting carbon monoxide of syngas mixtures with steam in the presence of iron chromate as catalyst at 673 K.

CO(g) + 3 H2(g) CO2 (g) + H2(g)  

This is called water-gas shift reaction.
