He matū te methane, ko tōna tauira matū ko CH4 (kotahi te ngota waro, e whā ngā ngota hauwai).

Whakataki Hua

He matū te methane, ko tōna tātai matū ko CH4 (kotahi te ngota o te waro, e whā ngā ngota o te hauwai). He hydride rōpū-14, ko te alkane tino māmā rawa atu, ā, koia te wāhanga matua o te hau māori. Nā te nui o te methane i runga i te Ao, he wahie ātaahua, ahakoa he uaua te hopu me te penapena nā tōna āhua hau i raro i ngā āhuatanga noa mō te pāmahana me te pēhanga.
Kei raro i te whenua me raro i te papa moana te methane tūturu. Ina tae ki te mata me te āhuarangi, ka mōhiotia ko te methane āhuarangi. Kua piki ake te kukū methane āhuarangi o te Ao mā te 150% mai i te tau 1750, ā, e 20% o te tapeke o ngā hau katiariki roa me ngā hau kati kōtuhi o te ao.

Whakatakotoranga

Te Tākai me te Tukunga

Tono

Hei Wahie
Ka whakamahia te methane hei wahie mō ngā oumu, ngā whare, ngā whakamahana wai, ngā oumu, ngā motuka, ngā tāpine, me ētahi atu mea. Ka tahuna ki te hāora hei hanga ahi.

I roto i te Ahumahi Matū
Ka hurihia te methane hei hau hanga, he ranunga o te hauota waro me te hauwai, mā te hanga hou i te mamaoa.

Ngā Whakamahinga

E whakamahia ana te methane i roto i ngā tukanga matū ahumahi, ā, ka taea te kawe hei wai whakamātao (hau māori waikura, LNG rānei). Ahakoa he taumaha ake ngā turuturu mai i te ipu wai whakamātao i te hau i te tīmatanga nā te nui haere o te mātotoru o te hau makariri, he mama ake te hau i te hau i te pāmahana taiao. He nui te hau māori e tohatohahia ana e ngā paipa hau, ko te methane te wāhanga matua.

1. Wahie
Ka whakamahia te methane hei wahie mō ngā oumu, ngā whare, ngā whakamahana wai, ngā oumu, ngā motuka, ngā tāpine, me ētahi atu mea. Ka tahuna ki te hāora hei hanga wera.

2. Hau māori
He mea nui te methane mō te whakaputa hiko mā te tahu hei wahie i roto i te tāwhana hau, i te whakaputa mamaoa rānei. Ki te whakatauritea ki ētahi atu wahie hauwaiwai, he iti ake te hauhā waro e puta mai ana i te methane mō ia waeine wera e tukuna ana. I te 891 kJ/mol pea, he iti ake te wera tahunga o te methane i tētahi atu hauwaiwai engari ko te ōwehenga o te wera tahunga (891 kJ/mol) ki te papatipu ngota (16.0 g/mol, ko te 12.0 g/mol he waro) e whakaatu ana ko te methane, te hauwaiwai māmā rawa, e whakaputa ana i te wera nui ake mō ia waeine papatipu (55.7 kJ/g) i ētahi atu hauwaiwai matatini. I roto i te maha o ngā tāone, ka tukuna te methane ki roto i ngā kāinga mō te whakamahana me te tunu kai o te whare. I roto i tēnei horopaki e mōhiotia whānuitia ana ko te hau māori, e kiia ana he 39 megajoules ia mita pūtoru, 1,000 BTU rānei ia putu pūtoru paerewa.

Ko te methane i roto i te āhua o te hau māori kua kōpeketia ka whakamahia hei wahie waka, ā, e kīia ana he pai ake mō te taiao i ērā atu wahie pūmua pērā i te penehīni/penehīni me te tīhiera. Kua whakahaerehia he rangahau mō ngā tikanga mimiti o te penapena methane hei wahie waka.

3. Hau māori wai
Ko te hau māori wai (LNG) he hau māori (te nuinga he methane, CH4) kua hurihia hei wai hei ngāwari ake te penapena, te kawe rānei. E hiahiatia ana ngā waka tāke LNG utu nui hei kawe i te methane.

Tata ki te 1/600 o te rahinga o te hau māori i roto i te āhua hau, he hau te rahi. Kāore he kakara, kāore he tae, kāore he paitini, ā, kāore hoki e waikura. Ko ētahi o ngā tūponotanga ko te mura i muri i te mimiti ki te āhua hau, te hukapapa, me te hemokai.

4. Wahie rōkete wai-methane
Ka whakamahia te methane wai kua parakore hei wahie mō te rōkete. E ai ki ngā pūrongo, he pai ake te methane i te hinuhinu, arā, he iti ake te waro e whakatakotoria ana ki ngā wāhanga o roto o ngā motuka rōkete, ā, ka whakaiti i te uaua o te whakamahi anō i ngā whakakaha.

He nui te methane i ngā wāhi maha o te Pūnaha Rā, ā, tera pea ka hauhaketia mai i te mata o tētahi atu tinana o te pūnaha rā (ina koa, mā te whakamahi i te hanga methane mai i ngā rauemi o te rohe i kitea i Mars, i Titan rānei), hei whakarato wahie mō te haerenga hoki.

5. Ngā rauemi matū
Ka hurihia te methane hei hau whakahiato, he ranunga o te hauota waro me te hauwai, mā te hanga hou i te mamaoa. Ka whakamahia e tēnei tukanga endergonic (e hiahia ana ki te pūngao) ngā whakakorikori, ā, me nui te pāmahana, tata ki te 700–1100 °C.

Ngā mahi āwhina tuatahi

Whakapā Kanohi:Kāore e hiahiatia ana mō te hau. Mēnā kei te whakapaetia he hukapapa, horoia ngā kanohi ki te wai matao mō te 15 meneti ka rapu awhina hauora tonu.
Whakapā Kiri:Kāore he hau e hiahiatia ana. Mēnā ka pā ki te kiri, ka whakapaetia rānei he hukapapa, tangohia ngā kākahu kua poke, ka horoia ngā wāhi kua pāngia ki te wai māhana. KAUA E WHAKAMAHI I TE WAI WERA. Me tere te tirotiro a te tākuta i te tūroro mēnā kua puta he pupuhi o te mata o te kiri, he hukapapa hohonu rānei i te pānga ki te hua.
Te manawa:ME WHAKATŪPATO wawe te rata hauora mō ngā āhuatanga katoa o te manawa nui. ME WHAKAWHITI NGĀ TANGATA WHAKAORA I NGĀ TAPUTAPU MANAWA WHAKAPŪMAU. Me āwhina ngā tāngata i manawahia ki tētahi wāhi kore paru, ā, me manawa ki te hau hou. Mena he uaua te manawa, me hoatu he hāora. Me neke ngā tāngata kāore i te mōhio ki tētahi wāhi kore paru, ā, ki te tika, me hoatu he whakaora horihori me te hāora tāpiri. Me whai tohumate, ā, me tautoko te maimoatanga.
Te horomitanga:Kāore i raro i te whakamahinga noa. Rapua he awhina hauora mēnā ka puta ngā tohu.
Ngā Tuhipoka ki te Tākuta:Whakaorahia ngā tohumate.

Te methane o waho o te whenua
Kua kitea te methane, e whakaponohia ana rānei kei runga i ngā aorangi katoa o te pūnaha rā me te nuinga o ngā marama nunui. Haunga a Māta, e whakaponohia ana i ahu mai i ngā tukanga abiotic.
Te methane (CH4) i runga i a Mātaotao – ngā pūtake me ngā totohu pea.
Kua whakaarohia te methane hei pūkaha mō ngā rōkete i ngā misioni o Mars a meake nei nā te mea ka taea te hanga i tēnei mea i runga i te aorangi mā te whakamahi rauemi i roto i te wāhi.[58] Ka taea te whakamahi i tētahi urutaunga o te tauhohenga methanation Sabatier me tētahi moenga whakakorikori whakauru me te nekehanga wai-hau whakamuri i roto i tētahi tauhohenga kotahi hei whakaputa methane mai i ngā rauemi mata e wātea ana i Mars, mā te whakamahi i te wai mai i te oneone o raro o Mars me te hauhā waro i roto i te āhuarangi o Mars.

Ka taea te whakaputa i te methane mā te tukanga kore-koiora e kiia nei ko te "serpentinization[a] e uru ana te wai, te hauhā waro, me te kohuke olivine, e mōhiotia ana he mea noa i runga i a Tāwhirimātea."
