Question
What do you understand by the term water-gas shift reaction?
Advertisements
Solution
Water shift reaction is a reaction of carbon monoxide of syngas mixture with steam in the presence of a catalyst as:
\[\ce{CO_{(g)} + H2O_{(g)} ->[673 K][Catalyst] CO_{2(g)} + H_{2(g)}}\]
This reaction is used to increase the yield of dihydrogen obtained from the coal gasification reaction as:
\[\ce{C_{(s)} + H2O_{(g)} -> CO_{(g)} + H_{2(g)}}\]
