Concept:

The Bosch process is used to produce hydrogen gas from water gas.

Explanation:

Water gas is a mixture of carbon monoxide and hydrogen:

\mathrm{CO} + \mathrm{H}_2

In the Bosch process, steam is passed over the water gas mixture with a catalyst, converting carbon monoxide to carbon dioxide:

\mathrm{CO} + \mathrm{H}_2\mathrm{O} \rightarrow \mathrm{CO}_2 + \mathrm{H}_2

The carbon dioxide is then removed, leaving hydrogen gas.
