Question:

Is there any smell of methane

Is there any smell of methane

Answer:

Less than 1% of hydrogen (H2), less than 0.4% oxygen (O2) and hydrogen sulfide (H2S) from 0.1% to 3%. Because the methane contains a small amount of hydrogen sulfide, so slightly smell.
Methane is the main component of methane, methane from 50% to 80% (CH4), carbon dioxide (CO2) from 20% to 40% (), nitrogen dioxide (N2)
Methane is not pure CH4, containing H2S and other odor substances. H2S is the smell of rotten eggs
