In Bosch process hydrogen is obtained from

Options

A. natural gas
B. water
C. water gas
D. None of these

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Bosch Process:**
The Bosch process is a method for producing hydrogen gas. It involves the reaction of steam with carbon (in the form of coke) at high temperatures.

2. **Chemical Reaction:**
The main reaction in the Bosch process can be represented as:
\[ \text{C (coke)} + \text{H}_2\text{O (steam)} \rightarrow \text{CO (carbon monoxide)} + \text{H}_2 (hydrogen gas) \]
This reaction indicates that when steam is passed over red-hot coke, hydrogen gas is produced along with carbon monoxide.

3. **Formation of Water Gas:**
The term "water gas" refers to the mixture of hydrogen and carbon monoxide. The overall reaction can also be represented as:
\[ \text{C} + \text{H}_2\text{O} \rightarrow \text{H}_2 + \text{CO} \]
Additionally, carbon monoxide can react further with steam to produce more hydrogen:
\[ \text{CO} + \text{H}_2\text{O} \rightarrow \text{H}_2 + \text{CO}_2 \]
Thus, the final products include hydrogen gas and carbon dioxide.

4. **Catalyst Used:**
In the Bosch process, Iron Chromate is used as a catalyst to facilitate the reaction and increase the efficiency of hydrogen production.

5. **Conclusion:**
Therefore, in the Bosch process, hydrogen is obtained in the form of water gas, which is a mixture of hydrogen and carbon monoxide.

**Final Answer:**
In the Bosch process, hydrogen is obtained from water gas.
