Background: Consequently, steam reforming typically employs an excess of H
2O. Additional hydrogen can be recovered from the steam by use of carbon monoxide through the water gas shift reaction, especially with an iron oxide catalyst. This reaction is also a common industrial source of carbon dioxide:
Question: How can it be recovered through steam?
Answer:<extra_id_0>.
<extra_id_0> use of carbon monoxide through the water gas shift reaction<extra_id_1>
