			== Description ==
			<blockquote><q>Methane is a combustible fuel. It is refined from [[Ice (Volatiles)]]</q>

			'''- [[Stationpedia]]'''</blockquote>'''Methane''' or CH'''<sub>4</sub>''' is a combustible gas in the presence of Oxygen and the breathing gas of the [[Zrilian]] species. The main source of Methane on most [[planets]] is in the form of [[Ice (Volatiles)]] that can be mined on the surface. Methane will autoignite at 300 Celsius or above in the presence of [[Oxygen]], and autoignite at 50 Celsius or above in the presence of [[Nitrous Oxide]].

			=== Composition ===
			Its combustion generates [[Pollutant\|Pollutants]], which are also formed through the evaporation of [[Liquid Sodium Chloride]]. With the fact it's also toxic to humans and [[plants]], it is possible it's not actually methane but a close relative of it.

			Possible compound: CH<sub>3</sub>Cl (Chloromethane)

			== Usage ==
			''See also: [[Fuel]]''

			Different ratios of Methane and Oxygen will produce different temperatures and pressures during combustion. Combustion will create a large amount of Heat, [[pressure]], and [[Carbon Dioxide]]. This reaction is useful inside a [[Furnace]] for smelting [[ores]] and creating alloys, but can be catastrophic when inside a [[Canister]] or a [[room]].

			These are the combustion reactions of methane:

			{{Combustion\|Fuel=Methane, 2\|Oxidizer=Oxygen, 1\|OutputA=Carbon Dioxide, 6\|OutputB=Pollutant, 3\|ShowAutoignition=true}}

			{{Combustion\|Fuel=Methane, 1\|Oxidizer=Nitrous Oxide, 1\|OutputA=Carbon Dioxide, 2\|OutputB=Nitrogen, 2\|ShowAutoignition=true}}

			{{Combustion\|Fuel=Methane, 3\|Oxidizer=Ozone, 2\|OutputA=Carbon Dioxide, 6\|OutputB=Pollutant, 3\|OutputC=Steam, 1\|ShowAutoignition=true}}

			Since both reactions results in same amount of heat, but the one with [[Nitrous]] Oxide results with less moles, it produces much more heat per amount of matter (2.25 times more heat [[energy]] per mole of reaction products). Also, [[Nitrogen]] has lower heat capacity than [[pollutant]], which results in even higher temperature.

			The reaction rate by default (for example: in [[atmosphere]]) depends on temperature as clamp01(1 / (0.002 * (T<sub>C</sub> + 273.0)<sup>1.6</sup> + 0.05) / 5 for oxygen as an oxidizer, and clamp01(1 / (0.0025 * (T<sub>C</sub> + 273.0)<sup>1.01</sup> + 0.05) / 5 for nitrous oxide or [[ozone]]. Thus, the maximum default reaction rate is 0.2 and is valid at temperatures below 211C when without nitrous oxide and 107C when enough nitrous oxide is present (>~5%). After that reaction rate decreases logarithmically. At temperatures above 460C, nitrous enriched fuel combusts faster (at approx. 2x rate) than oxygen only. At higher temperatures, the difference is even greater, thus making the reaction more efficient and violent. Some devices (like [[Combustor]] or [[Kit (Gas Fuel Generator)\|Gas Fuel Generator]]) increases rate of reaction (to 0.9 i.e. 90% in both cases).

			If a combusting gas mix contains Volatiles, NOS, and O2, they all will react proportionally at same rate, according to aforementioned reactions (i.e. at 90% reaction rate and ideally balanced mix, each component will decrease by 90% from it's original amount). When mix is unbalanced and have either excess of volatiles or oxidizers, then proportions decrease accordingly, i.e. with excess of volatiles, only the amount of volatiles corresponding to amount of oxidizers (2 per Oxygen, 1 per Nitrous Oxide) will decrease proportionally; with excess of oxidizers, similarly, only the amount of oxidizers corresponding to the amount of volatiles is decreased at reaction rate, i.e. oxygen reacts at half the rate of nitrous oxide.

			Volatiles have a specific heat of 20.4 Joule / mol.

			=== Notes ===

			* The Specific heat of 20.4 Joule / mol is in-between the specific heat of [[Hydrogen]] and Methane.
			* The actual Autoignition temperature of Chloromethane in Oxygen is 625 °C (1,157 °F; 898 K), the game grossly underestimated the iginition temperature by about 1.56 times.
			* Concentrations of methane aboute 1% in atmosphere are lethal to plants, keep attention on that designing a greenhouse, because the [[Portable Composter]] [[Kit (Advanced Composter)\|Advanced Composter]] will release Volatiles during the process.
			* Enthalpy of Methane (CH<sub>4</sub>) combustion is precisely 286 kJ/mol (multiplied by 2 when using Nitrous Oxide or Ozone as oxidizers).
			* As far as [[rocketry]] is concerned, Methane have a mass of 62.5 mol/kg.
			* Given the above, Volatiles have a molar mass of 16, suggesting it really is methane (CH₄).
