water gas

Chemistry

A mixture of carbon monoxide and hydrogen produced by passing steam over hot carbon (coke):
$H_{2} O (g) + C (s) \to {CO (g) + H}_{2} (g)$
The reaction is strongly endothermic but the reaction can be used in conjunction with that for producer gas for making fuel gas. The main use of water gas before World War II was in producing hydrogen for the Haber process. Here the above reaction was combined with the water-gas shift reaction to increase the amount of hydrogen:
${CO + H}_{2} O ⇌ {CO}_{2} + H_{2}$
Most hydrogen for the Haber process is now made from natural gas by steam reforming.

Chemical Engineering

A mixture of carbon monoxide and hydrogen gas produced by the exothermic reaction of steam on heated carbon:
$C + H_{2} O_{(s t e a m)} \to C O + H_{2}$

Water gas burns with a non-luminous bluish flame and is also known as blue water gas. Water gas was once produced from coke, and was in turn produced from coal. Prior to the use of steam reforming of natural gas, the main use before the Second World War was for (p. 408) the production of hydrogen in the Haber process and was combined with the water-gas shift reaction to increase the amount of hydrogen produced.
