Question

Which gas is present in biogas and CNG?

Answer 1

Answer:

Biogas consists mainly of methane (CH4, 55-65%) and carbon dioxide (CO2, 35-45%) and the calorific value of biogas is ~19500 KJ/Kg. Methane is a valuable form of gas, as it is an efficient energy carrier with a wide range of uses. The amount of CO2 that is produced corresponds to the amount of CO2 captured when the biomass was created, making biogas carbon neutral.
