Producer gas contains

Options

A. `CO_(2)+H_(2)`
B. `CO_(2)+CH_(4)`
C. `CO++H_(2)`
D. `CO+CH_(4)`

Answer

**Step-by-Step Solution:**

1. **Understanding Producer Gas**: Producer gas is a type of gas that is produced by the gasification of biomass or coal. It is also known as water gas, wood gas, or coal gas.

2. **Composition of Producer Gas**: The main components of producer gas include:
- Nitrogen (N₂)
- Carbon monoxide (CO)
- Carbon dioxide (CO₂)
- Hydrogen (H₂)

3. **Percentage Composition**: The approximate percentage composition of the gases in producer gas is:
- Nitrogen: 55%
- Carbon monoxide: 29%
- Carbon dioxide: 5.5%
- Hydrogen: 10.5%

4. **Analyzing the Options**: The question provides several options regarding the components of producer gas:
- Carbon dioxide + hydrogen
- Carbon dioxide + methane
- Carbon monoxide + hydrogen
- Carbon monoxide + methane

5. **Eliminating Incorrect Options**:
- **Carbon dioxide + methane**: Producer gas does not contain methane, so this option can be eliminated.
- **Carbon monoxide + methane**: Again, producer gas does not contain methane, so this option can also be eliminated.

6. **Choosing Between Remaining Options**:
- The remaining options are:
- Carbon dioxide + hydrogen
- Carbon monoxide + hydrogen
- While both carbon dioxide and hydrogen are present in producer gas, carbon monoxide is the major component (29%), while carbon dioxide is only 5.5%. Therefore, the option that includes carbon monoxide is more accurate.

7. **Conclusion**: The correct answer is that producer gas contains carbon monoxide and hydrogen.

**Final Answer**: Producer gas contains carbon monoxide and hydrogen.
