Question

main components of bio gas or gobar gas​

Answer 1

Biogas is an emerging renewable energy source which is obtained through degradation of organic matter by bacteria under anaerobic conditions. Raw biogas contains about 55–65% methane (CH4), 30–45% carbon dioxide (CO2), traces of hydrogen sulphide (H,S), and fractions of water vapour.

Answer 2

This type of biogas comprises primarily methane and carbon dioxide. Another type of gas generated by use of biomass is wood gas, which is created by gasification of wood or other biomass. This type of gas is also comprised primarily of nitrogen, hydrogen, and carbon monoxide, with trace amounts of methane.
