What is the percentage of methane in biogas?
Answers
The percentage of Methane in Biogas varies. However, the general breakdown is like this: Methane (CH4) 55 – 75%, Carbon Dioxide CO2 – 25-50% and other trace gases such as Nitrogen (N2), Hydrogen (H2), Hydrogen Sulphide (H2S) etc.
Biogas is produced as a result of breakdown of organic matter (such as agricultural and human waste etc.), by anaerobic organisms. Biogas is a cheap alternative to cooking gas and used as fuel in other applications.
Answer:
The percentage of ‘methane gas’ in biogas is 50 - 65%.
Explanation:
The biogas is an extensive composition that is produced when the organics matter breakdown into simpler substances in the ‘absence of oxygen’. It can be produced from agricultural waste, municipal waste, sewage waste etc.
It majorly contains methane, carbon dioxide and ‘small amounts’ of hydrogen sulphide gas. It is a form of renewable energy that can be converted to heat and electrical energy.
