Methane Gas
Methane gas is the simplest hydrocarbon.Widely existing in natural gas, biogas, coal mine gas, is a high-quality gas fuel, but also the production of synthetic gas and many chemical products of important raw materials.Methane is a more active greenhouse gas than carbon dioxide at the molecular level, but it is less abundant in the atmosphere
