A variety of positive ions derived from methane have been observed, mostly as unstable species in low-pressure gas mixtures. Some of these have been detected in outer space.

Methanium can also be produced as diluted solutions from methane with superacids. Despite the strength of its C—H bonds, there is intense interest in catalysts that facilitate C—H bond activation in methane and other lower numbered alkanes.

Methane's heat of combustion is Peters four-step chemistry is a systematically reduced four-step chemistry which explains the burning of methane.

Given appropriate conditions, methane reacts with halogen radicals as follows:. This mechanism for this process is called free radical halogenation.

It is initiated when UV light or some other radical initiator like peroxides produces a halogen atom.

The methyl radical then reacts with a molecule of the halogen to form a molecule of the halomethane, with a new halogen atom as byproduct.

Methane is used in industrial chemical processes and may be transported as a refrigerated liquid liquefied natural gas, or LNG. While leaks from a refrigerated liquid container are initially heavier than air due to the increased density of the cold gas, the gas at ambient temperature is lighter than air.

Gas pipelines distribute large amounts of natural gas, of which methane is the principal component.

Methane is used as a fuel for ovens, homes, water heaters, kilns, automobiles, [21] [22] turbines, and other things.

Activated carbon is used to store methane. Refined liquid methane is used as a rocket fuel , [23] when combined with liquid oxygen , as in the BE-4 and Raptor engines.

As the major constituent of natural gas , methane is important for electricity generation by burning it as a fuel in a gas turbine or steam generator.

Compared to other hydrocarbon fuels , methane produces less carbon dioxide for each unit of heat released. However, it produces more heat per mass In many cities, methane is piped into homes for domestic heating and cooking.

In this context it is usually known as natural gas , which is considered to have an energy content of 39 megajoules per cubic meter, or 1, BTU per standard cubic foot.

Liquefied natural gas LNG is predominantly methane CH 4 converted into liquid form for ease of storage or transport.

As a rocket fuel, methane offers the advantage over kerosene of depositing less carbon on the internal parts of rocket motors, reducing the difficulty of re-use of boosters.

Natural gas , which is mostly composed of methane, is used to produce hydrogen gas on an industrial scale. More than 50 million metric tons are produced annually worldwide , principally from SMR of natural gas.

Very large quantities of hydrogen are used in the industrial synthesis of ammonia. Additional hydrogen is obtained by the reaction of CO with water via the water-gas shift reaction.

Methane is also subjected to free-radical chlorination in the production of chloromethanes, although methanol is a more typical precursor.

The two main routes for geological methane generation are i organic thermally generated, or thermogenic and ii inorganic abiotic.

Most methane in sedimentary basins is thermogenic; therefore, thermogenic methane is the most important source of natural gas.

Thermogenic methane components are typically considered to be relic from an earlier time. Generally, formation of thermogenic methane at depth can occur through organic matter breakup, or organic synthesis.

Both ways can involve microorganisms methanogenesis , but may also occur inorganically. The processes involved can also consume methane, with and without microorganisms.

The more important source of methane at depth crystalline bedrock is abiotic. Abiotic means that methane is created from inorganic compounds, without biological activity, either through magmatic processes or via water-rock reactions that occur at low temperatures and pressures, like serpentinization.

Most of Earth's methane is biogenic and is produced by methanogenesis , [30] [31] a form of anaerobic respiration only known to be conducted by some members of the domain Archaea.

Rice fields also generate large amounts of methane during plant growth. The net reaction of methanogenesis is:.

The final step in the process is catalyzed by the enzyme methyl coenzyme M reductase MCR. Most of the subseafloor is anoxic because oxygen is removed by aerobic microorganisms within the first few centimeters of the sediment.

Below the oxygen replete seafloor, methanogens produce methane that is either used by other organisms or becomes trapped in gas hydrates.

There is little incentive to produce methane industrially. Methane is produced by hydrogenating carbon dioxide through the Sabatier process.

Methane is also a side product of the hydrogenation of carbon monoxide in the Fischer—Tropsch process , which is practiced on a large scale to produce longer-chain molecules than methane.

Example of large-scale coal-to-methane gasification is the Great Plains Synfuels plant, started in in Beulah, North Dakota as a way to develop abundant local resources of low-grade lignite , a resource that is otherwise difficult to transport for its weight, ash content, low calorific value and propensity to spontaneous combustion during storage and transport.

Power to methane is a technology that uses electrical power to produce hydrogen from water by electrolysis and uses the Sabatier reaction to combine hydrogen with carbon dioxide to produce methane.

As of , this is mostly under development and not in large-scale use. Theoretically, the process could be used as a buffer for excess and off-peak power generated by highly fluctuating wind generators and solar arrays.

However, as currently very large amounts of natural gas are used in power plants e. CCGT to produce electric energy, the losses in efficiency are not acceptable.

Methane can be produced by protonation of methyl lithium and methylmagnesium iodide. In practice, a requirement for pure methane will be filled with a steel gas bottle from standard suppliers.

Methane was discovered and isolated by Alessandro Volta between and when studying marsh gas from Lake Maggiore. The major source of methane is extraction from geological deposits known as natural gas fields , with coal seam gas extraction becoming a major source see Coal bed methane extraction , a method for extracting methane from a coal deposit, while enhanced coal bed methane recovery is a method of recovering methane from non-mineable coal seams.

It is associated with other hydrocarbon fuels, and sometimes accompanied by helium and nitrogen. Methane is produced at shallow levels low pressure by anaerobic decay of organic matter and reworked methane from deep under the Earth's surface.

In general, the sediments that generate natural gas are buried deeper and at higher temperatures than those that contain oil.

Methane is generally transported in bulk by pipeline in its natural gas form, or LNG carriers in its liquefied form; few countries transport it by truck.

This level is over twice as high as at any time in the last , years. The Earth's oceans are a potential important source of Arctic methane.

Methane is an important greenhouse gas with a global warming potential of 34 compared to CO 2 potential of 1 over a year period, and 72 over a year period.

From to sharp rises in levels of atmospheric methane have been recorded. Climate change can increase atmospheric methane levels by increasing methane production in natural ecosystems, forming a Climate change feedback.

Methane clathrates also known as methane hydrates are solid cages of water molecules that trap single molecules of methane.

These deposits are both a potential source of methane fuel as well as a potential contributor to global warming. For example, a relatively newly discovered source of methane was discovered in an ultraslow spreading ridge in the Arctic.

Methane is abundant in many parts of the Solar system and potentially could be harvested on the surface of another solar-system body in particular, using methane production from local materials found on Mars [60] or Titan , providing fuel for a return journey.

Methane has been detected on all planets of the solar system and most of the larger moons. With the possible exception of Mars , it is believed to have come from abiotic processes.

The Curiosity rover has documented seasonal fluctuations of atmospheric methane levels on Mars. These fluctuations peaked at the end of the Martian summer at 0.

Methane has been proposed as a possible rocket propellant on future Mars missions due in part to the possibility of synthesizing it on the planet by in situ resource utilization.

Methane could be produced by a non-biological process called serpentinization [a] involving water, carbon dioxide, and the mineral olivine , which is known to be common on Mars.

In November , methane was first scientifically identified by Italian physicist Alessandro Volta in the marshes of Lake Maggiore straddling Italy and Switzerland.

Volta was inspired to search for the substance after reading a paper written by Benjamin Franklin about "flammable air".

The name "methane" was coined in by the German chemist August Wilhelm von Hofmann. Etymologically, the word " methane " is coined from the chemical suffix " -ane ", which denotes substances belonging to the alkane family; and the word " methyl ", which is derived from the German " methyl " A.

The radical is named after this because it was first detected in wood alcohol. The chemical suffix " -ane " is from the coordinating chemical suffix " -ine " which is from Latin feminine suffix " -ina " which is applied to represent abstracts.

The coordination of "-ane", "-ene", "-one", etc. Methane is nontoxic , yet it is extremely flammable and may form explosive mixtures with air.

Methane off-gas can penetrate the interiors of buildings near landfills and expose occupants to significant levels of methane. Some buildings have specially engineered recovery systems below their basements to actively capture this gas and vent it away from the building.

Methane gas explosions are responsible for many deadly mining disasters. From Wikipedia, the free encyclopedia. For other uses, see CH4 disambiguation.
