4. Hydrogen purification
The processes we've just seen lead to the production of hydrogen in a mixture with other compounds (essentially CO, CO 2 , methane if the feedstock consists of hydrocarbons, and oxygen for electrolysis). A purification step is therefore necessary before use.
4.1 CO removal by chemical processes
4.1.1 Water Gas Shift reaction
The conversion of carbon monoxide by steam enables an initial purification of the synthesis gas and contributes to increasing...
