Question

Hydrogen can be prepared by mixing steam and water gas at ${500}^{\circ }C$ in the presence of $F{e}_2{O}_3$ and $C{r}_2{O}_3$. This process is called:

• A. Nelson process
• B. Serpeck’s process
• C. Bosch process
• D. Parke’s process

Answer 1

The correct option is C Bosch process

In the Bosch process, large quantities of hydrogen are produced from cheap raw materials such as water and coke. When steam is passed over red hot coke(carbon) at a temperature of about $1200{}^{\circ }C$, a mixture of carbon dioxide and hydrogen is produced. Here $F{e}_2{O}_3$ acts as a catalyst and $C{r}_2{O}_3$ acts as a promoter.
