Question

The catalyst used in the manufacture of hydrogen by Bosch's process is:

• A. $F{e}_2{O}_3$
• B. $C{r}_2{O}_3$
• C. both $A$ and $B$
• D. $Cu$

Answer 1

The correct option is C both $A$ and $B$

In the Bosch process, hydrogen is produced from raw materials such as water and coke. When steam is passed over red-hot coke at a temperature of about ${1200}^{0}C$, a mixture of carbon monoxide and hydrogen is produced. Excess steam is mixed with the carbon monoxide and hydrogen and passed over a catalyst which could either be iron(III) oxide($F{e}_2{O}_3$) or chromium(III) oxide($C{r}_2{O}_3$), at a high temperature.
