The Methane Gas


Methane (Greek methy wine, and -ano suffix) 2 is the simplest alkane hydrocarbon with the chemical formula CH

Each of the hydrogen atoms bonded to carbon is through a covalent bond. Is a non-polar substance in the form of gas at ordinary temperatures and pressures. It is colorless, odorless and insoluble in water.

In nature, it occurs as an end product of anaerobic plant putrefaction. This natural process can be exploited to produce biogas. Many anaerobic microorganisms is generated using the CO2 as a final electron acceptor.

Constitute up to 97% natural gas. In the coal mine gas is called and is very dangerous because it is highly flammable and explosive. However in recent decades has become important commercial exploitation of methane gas from coal as an energy source.

Methane is a relatively potent greenhouse gas effect that contributes to global warming of planet Earth as it has a global warming potential 23.3 This means that in a time measurement of 100 years every kg of CH4 warms the earth 23 times the same mass of CO2, however there are approximately 220 times more carbon dioxide in the atmosphere of Earth methane so that methane contributes least to greenhouse manner.
