State a source of hydrogen for the Haber process
Question
State a source of hydrogen for the Haber process
Solution
A source of hydrogen for the Haber process is natural gas. Here are the steps:
-
Natural gas, which is primarily methane (CH4), is a rich source of hydrogen.
-
The methane is reacted with steam in a reforming process, which produces hydrogen and carbon monoxide.
-
The carbon monoxide is then reacted with more steam in a water-gas shift reaction to produce additional hydrogen and carbon dioxide.
-
The hydrogen is then separated from the other gases, typically using pressure swing adsorption, and is ready to be used in the Haber process.
