197. Washington — A colorless hydrocarbon gas, methane doesn't get nearly the attention that its partner in crime, carbon dioxide, receives.

198. Cracked gas in high-temperature causes methane carbon isotope to heavy.

199. Like a frozen asteroid belt, it’s littered with chunks of ice and frozen methane and ammonia.

200. This dissertation study about the methane yield method, methanogen active in history and methanogen type by synthesize using isotopes analysis method and compare coalbed gas with pyrolysis gas.
