What is the major constituent of Biogas?Options :ButaneMethaneHydrogen sulphidePropane

1. Break Down the Problem

To determine the major constituent of biogas, we will consider the common components found in biogas and compare the options provided.

2. Relevant Concepts

Biogas is primarily produced through the anaerobic digestion of organic materials. The major components of biogas typically include:

• Methane (CH₄)
• Carbon dioxide (CO₂)
• Smaller amounts of other gases like hydrogen sulfide (H₂S).

3. Analysis and Detail

The options given are:

1. Butane (C₄H₁₀)
2. Methane (CH₄)
3. Hydrogen sulfide (H₂S)
4. Propane (C₃H₈)

Among these:

• Butane and Propane are alkane gases that are generally not found in significant quantities in biogas.
• Hydrogen sulfide is present in small amounts but is not the predominant component.
• Methane is the primary gas in biogas, typically making up about 50-70% of its composition.

4. Verify and Summarize

Given the composition of biogas and the options provided, it is clear that the major constituent is methane.

Final Answer

Methane is the major constituent of biogas.
