Gobar gas mainly contains-

The correct answer is methane.

Key Points

• Gobar gas, also known as biogas, is primarily composed of methane (CH₄), which typically constitutes 50-75% of the gas.
• Methane is the main combustible component in biogas, making it a clean and renewable energy source.
• Biogas is produced through the anaerobic digestion of organic matter, such as cow dung, in the absence of oxygen.
• The high concentration of methane in gobar gas makes it suitable for applications such as cooking, heating, and electricity generation.
• In addition to methane, gobar gas also contains smaller amounts of carbon dioxide (CO₂), hydrogen sulfide (H₂S), and water vapor.

Additional Information

• Methane (CH₄):
  • Methane is a colorless, odorless, and highly flammable gas.
  • It is the simplest alkane and a potent greenhouse gas when released into the atmosphere.
• Anaerobic Digestion:
  • Anaerobic digestion is a biological process that breaks down organic material in the absence of oxygen to produce biogas.
  • The byproduct of this process is nutrient-rich slurry, which can be used as organic fertilizer.
• Uses of Biogas:
  • Biogas is widely used for cooking, heating, and as a fuel for electricity generation.
  • It is also being explored as a vehicle fuel in the form of compressed biogas (CBG).
• Environmental Benefits:
  • Using biogas reduces dependence on fossil fuels and helps in reducing greenhouse gas emissions.
  • It also addresses waste management issues by utilizing organic waste effectively.
