Methane (US: /ˈmɛθeɪn/ or UK: /ˈmiːθeɪn/) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydride and the simplest alkane, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure.
A gas hydrate that contains methane as the guest molecule; It occurs both in deep sedimentary structures, and as outcrops on the ocean floor
Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills.
Methane, also known as methyl hydride or marsh gas, is a gas extensively found in nature, which is very used as combustible.
Formula and structure: The methane chemical formula is CH4 and is also written as Met. Its molar mass is 16.043 g mol-1. The molecule is the simplest organic compound and it is considered the base of more complex organic molecules. The methane molecule has a tetrahedral geometry with 4 hydrogen bound to a carbon atom. The carbon atom has a sp3 hybridization, thus it can be explained its geometry. Its chemical structure can be written as below, in the common representations used for organic molecules.
Methane is mostly extracted from natural gas due it represents 87% of the total composition material. However, there are some processes to produce methane through organic or inorganic synthesis; for example through the reaction between carbon monoxide and hydrogen. It is the simplest route to produce methane and it is used a nickel catalyst and high temperature:
CO + 3H2 → CH4 + H2O
Other route is the reaction of water and carbon dioxide in a reaction that uses a ruthenium electrode. In nature, methane from decomposition of organic matter by bacteria and fughi is called methanogenesis and it is actually very used to produce methane from biomass in biotechnological processes:
Physical properties: Methane is a colorless and odorless gas. Its melting and boiling point are -183 ºC and -161 ºC, respectively. Its density is 0.716 g mL-1. Methane can easily ignite forming vapors lighter than air. It is not soluble in water, but is soluble in ethanol, ether, benezene, toluene and methanol.
Chemical properties: Methane is the most simple organic compound, so it is only formed by one carbon atoms and 4 hydrogen resulting in very light molecule that does not have the enough intermolecular interaction to form a liquid or solid. The total dipole moment in methane molecule is 0 impeding a high reactive of the specie and resulting in a very weak acid in solution.
Uses: Ethane is used as combustible in homes, mainly in water heaters and ovens. It is also an industrial combustible to turbines for generating electricity and also as a fuel alternative in automobiles.
Health effects / safety hazards: Methane is heavier than air, so that in high concentration it may cause asphyxiation by displaced the oxygen. It is extremely flammable and can ignite even at low temperatures. It may also explode by contact with strong oxidizing agents and halogens such as chlorine dioxide and nitrogen trifluoride or in contact with
While methane doesn't linger as long in the atmosphere as carbon dioxide, it is initially far more devastating to the climate because of how effectively it absorbs heat.
Because methane is so potent, and because we have solutions that reduce emissions, addressing methane is the fastest, most effective way to slow the rate of warming now.
Where is it coming from?
Methane can come from many sources, both natural and manmade. One major source of manmade methane emissions is the global oil and gas industry.
How do we fix the methane problem?
Until recently, little was known about where leaks were occurring, or the best way to fix them. In 2012, we kicked off a research series to better pinpoint leaks, and to find solutions.
A summary of our 16 studies of the whole U.S. supply chain shows methane emissions are significantly higher than we thought, reinforcing that major reductions from this sector are urgently needed.
In May 2016, the EPA finalized the first-ever national rule to directly limit methane emissions from oil and gas operations, unlocking a new opportunity to reduce climate pollution. We're working to defend these and related federal standards, which are under attack.
Methane is a colorless odorless gas. It is also known as marsh gas or methyl hydride. It is easily ignited. The vapors are lighter than air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is used in making other chemicals and as a constituent of the fuel, natural gas.
CAMEO Chemicals
Methane is a one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. -161℃). It has a role as a fossil fuel, a member of greenhouse gas and a bacterial metabolite. It is a mononuclear parent hydride, a one-carbon compound, a gas molecular entity and an alkane. It is a conjugate acid of a methanide.
