Hoʻolauna Huahana

He hui kemika ʻo Methane me ke ʻano kemika CH4 (hoʻokahi ʻātoma o ke kalapona a me ʻehā ʻātoma o ka hydrogen). He hydride hui-14 ia a ʻo ia ka alkane maʻalahi loa, a ʻo ia ke kumu nui o ke kinoea kūlohelohe. ʻO ka nui o ka methane ma ka Honua e lilo ia i wahie hoihoi, ʻoiai ʻo ka hopu ʻana a me ka mālama ʻana iā ia he mau pilikia ma muli o kona ʻano kinoea ma lalo o nā kūlana maʻamau no ka mahana a me ke kaomi.
Loaʻa ka methane kūlohelohe ma lalo o ka honua a ma lalo o ka papahele o ke kai. Ke hiki aku i ka ʻili a me ka lewa, ua kapa ʻia ʻo ia he methane atmospheric. Ua piʻi ka nui o ka methane atmospheric o ka Honua ma kahi o 150% mai ka makahiki 1750, a he 20% ia o ka huina o ka hoʻoulu ʻana o ka radiation mai nā kinoea ʻōmaʻomaʻo lōʻihi a me nā kinoea i hui pū ʻia ma ka honua holoʻokoʻa.

Ma ke ʻano he wahie
Hoʻohana ʻia ka Methane ma ke ʻano he wahie no nā umu, nā hale, nā mea hoʻomehana wai, nā umu ahi, nā kaʻa, nā turbine, a me nā mea ʻē aʻe. Hoʻopau ia me ka oxygen e hana i ke ahi.

Ma ka ʻoihana kemika
Hoʻololi ʻia ka Methane i ke kinoea synthesis, kahi hui ʻana o ke kalapona monoxide a me ka hydrogen, ma o ka hana hou ʻana i ka mahu.

Nā hoʻohana

Hoʻohana ʻia ka Methane i nā kaʻina hana kemika ʻoihana a hiki ke lawe ʻia ma ke ʻano he wai i hoʻomoʻa ʻia (kinoea kūlohelohe liquefied, a i ʻole LNG). ʻOiai ʻoi aku ke kaumaha o nā leaka mai kahi pahu wai i hoʻomoʻa ʻia ma mua o ka ea ma muli o ka piʻi ʻana o ka nui o ke kinoea anuanu, ʻoi aku ka māmā o ke kinoea ma ka mahana ambient ma mua o ka ea. Hoʻolaha nā paipu kinoea i nā nui he nui o ke kinoea kūlohelohe, ʻo ka methane ka ʻāpana nui.

1. Wahie
Hoʻohana ʻia ka Methane ma ke ʻano he wahie no nā umu, nā hale, nā mea hoʻomehana wai, nā umu ahi, nā kaʻa, nā turbine, a me nā mea ʻē aʻe. Hoʻopau ia me ka oxygen e hana i ka wela.

2. Kinoea kūlohelohe
He mea nui ka Methane no ka hana uila ma ke puhi ʻana iā ia ma ke ʻano he wahie i loko o kahi turbine kinoea a i ʻole ka mea hana mahu. Ke hoʻohālikelike ʻia me nā wahie hydrocarbon ʻē aʻe, hoʻopuka ka methane i ka carbon dioxide liʻiliʻi no kēlā me kēia anakahi o ka wela i hoʻokuʻu ʻia. Ma kahi o 891 kJ/mol, ʻoi aku ka haʻahaʻa o ka wela o ka methane ma mua o nā hydrocarbon ʻē aʻe akā ʻo ka lakio o ka wela o ka puhi ʻana (891 kJ/mol) i ka nuipa molekala (16.0 g/mol, nona ka 12.0 g/mol he kalapona) e hōʻike ana ʻo ka methane, ʻo ia ka hydrocarbon maʻalahi loa, e hoʻopuka i ka wela hou aʻe no kēlā me kēia anakahi nuipa (55.7 kJ/g) ma mua o nā hydrocarbons paʻakikī ʻē aʻe. Ma nā kūlanakauhale he nui, hoʻopili ʻia ka methane i loko o nā hale no ka hoʻomehana home a me ka kuke ʻana. Ma kēia ʻano, ʻike pinepine ʻia ʻo ia he kinoea kūlohelohe, kahi i manaʻo ʻia he 39 megajoules ka nui o ka ikehu no ka mika cubic, a i ʻole 1,000 BTU no ka wāwae cubic maʻamau.

Hoʻohana ʻia ka Methane ma ke ʻano o ke kinoea kūlohelohe i hoʻopaʻa ʻia e like me ka wahie no ke kaʻa a ua ʻōlelo ʻia he ʻoi aku ka maikaʻi o ke kaiapuni ma mua o nā wahie fossil ʻē aʻe e like me ka gasoline/petrol a me ka diesel. Ua hana ʻia ka noiʻi ʻana i nā ʻano adsorption o ka mālama ʻana i ka methane no ka hoʻohana ʻana ma ke ʻano he wahie no ke kaʻa.

3. Kinoea kūlohelohe i hoʻoheheʻe ʻia
ʻO ke kinoea kūlohelohe wai (LNG) he kinoea kūlohelohe (ʻo ka hapa nui he methane, CH4) i hoʻololi ʻia i ʻano wai no ka maʻalahi o ka mālama ʻana a i ʻole ka lawe ʻana. Pono nā moku LNG pipiʻi e lawe i ka methane.

ʻO ke kinoea kūlohelohe i hoʻoheheʻe ʻia ma kahi o 1/600 o ka nui o ke kinoea kūlohelohe i ke ʻano kinoea. He ʻala ʻole, ʻaʻohe kala, ʻaʻohe mea ʻawahia a ʻaʻole hoʻi e pala. ʻO nā pōʻino e komo pū me ka lapalapa ʻana ma hope o ka mahu ʻana i ke ʻano kinoea, ka hau ʻana, a me ka asphyxia.

4. Wahie rocket wai-methane
Hoʻohana ʻia ka methane wai i hoʻomaʻemaʻe ʻia e like me ka wahie rocket. Ua hōʻike ʻia ʻo Methane e hāʻawi i ka pono ma luna o ke kerosene o ka waiho ʻana i ka carbon liʻiliʻi ma nā ʻāpana o loko o nā motika rocket, e hōʻemi ana i ka paʻakikī o ka hoʻohana hou ʻana i nā mea hoʻoikaika.

Nui ka Methane ma nā wahi he nui o ka ʻōnaehana lā a hiki ke hōʻiliʻili ʻia ma luna o ka ʻili o kekahi kino ʻōnaehana lā (ʻoi aku hoʻi, me ka hoʻohana ʻana i ka hana methane mai nā mea kūloko i loaʻa ma Mars a i ʻole Titan), e hāʻawi ana i ka wahie no kahi huakaʻi hoʻi.

5. Meaʻai Kemika
Hoʻololi ʻia ka Methane i ke kinoea synthesis, kahi hui ʻana o ke kalapona monoxide a me ka hydrogen, ma o ka hoʻoponopono hou ʻana i ka mahu. Hoʻohana kēia kaʻina hana endergonic (e pono ai ka ikehu) i nā catalysts a koi i nā mahana kiʻekiʻe, ma kahi o 700–1100 °C.

Nā memo i ke kauka:E mālama ma ke ʻano he mau hōʻailona.

ʻO ka methane ma waho o ka honua
Ua ʻike ʻia ka methane a ua manaʻo ʻia paha aia ma nā hōkūhele āpau o ka ʻōnaehana lā a me ka hapa nui o nā mahina nui. Me ka ʻokoʻa paha o Mars, ua manaʻo ʻia ua hele mai ia mai nā kaʻina hana abiotic.
ʻO ka Methane (CH4) ma Mars - nā kumu kūpono a me nā poho.
Ua hāpai ʻia ka Methane ma ke ʻano he mea hoʻoulu rocket ma nā misionari Mars e hiki mai ana ma muli o ka hiki ke hana ʻia ma ka honua ma o ka hoʻohana ʻana i nā kumuwaiwai in situ.[58] Hiki ke hoʻohana ʻia kahi hoʻololi o ka hopena methanation Sabatier me kahi moena catalyst i hui pū ʻia a me kahi hoʻololi wai-kinoea hoʻohuli i loko o kahi reactor hoʻokahi e hana i ka methane mai nā mea maka i loaʻa ma Mars, me ka hoʻohana ʻana i ka wai mai ka lepo Martian a me ke kalapona dioxide i ka lewa Martian.

Hiki ke hoʻopuka ʻia ka Methane e ke kaʻina hana ʻole-biological i kapa ʻia ʻo "serpentinization[a] e pili ana i ka wai, ke kalapona dioxide, a me ka mineral olivine, ka mea i ʻike ʻia he mea maʻamau ma Mars.
