Question

what happens when biogas is mixed with hydrogen and oxygen?

NOTE:hydrogen and oxygen means not water but seperatly

Answer 1

The major components of Biogas are methane (CH₄) i.e 60-70 % and Carbon dioxide CO₂ (30-39%) .
Therefore methane (CH₄)does not react with H₂ i.e Hydrogen , but may undergo combustion in presence of Oxygen (O₂).

Reaction of Methane (CH₄​) with O₂
​CH₄ + 2O₂ → CO₂ + 2H₂O
