Metana (CH4)

Nā palena ʻenehana

ʻO ka Methane kahi mea hoʻohuihui me ke ʻano mole o CH4 a me ke kaumaha molekala o 16.043. ʻO ka Methane ka mea maʻalahi maʻalahi a me ka hydrocarbon me ka liʻiliʻi loa o ke kalapona (ʻo ka hydrogen nui loa). Hoʻolaha nui ʻia ka Methane ma ke ʻano a ʻo ia ka mea nui o ke kinoea maoli, biogas, pit gas, etc., i ʻike mau ʻia he kinoea. He kinoea kala ʻole a ʻala ʻole ka methane ma lalo o nā kūlana maʻamau. Ma lalo o nā kūlana maʻamau, paʻa ka methane a paʻakikī loa e hoʻoheheʻe i ka wai. ʻAʻole ia e hoʻopili me nā mea hoʻomake ikaika e like me ka potassium permanganate, ʻaʻole hoʻi e pane me nā waikawa ikaika a i ʻole ka alkali. Akā, ma lalo o kekahi mau kūlana, loaʻa pū kekahi methane i kekahi mau hopena. He wahie koʻikoʻi ka methane. ʻO ia ka mea nui o ke kinoea maoli, e helu ana ma kahi o 87%. Hoʻohana ʻia ia ma ke ʻano he wahie maʻamau no nā mea hoʻomehana wai a me nā umu ahi no ka hoʻāʻo ʻana i ka waiwai calorific. Hiki ke hoʻohana ʻia ka Methane e like me ke kinoea maʻamau a me ke kinoea calibration no ka hana ʻana i nā mea hoʻoheheʻe kinoea. Hiki ke hoʻohana ʻia ma ke ʻano he kumu kalapona no nā cell solar, amorphous silicon film vapor chemical deposition, a ma ke ʻano he mea maka no ka lāʻau lapaʻau a me ka synthesis. Hoʻohana ʻia ka Methane i nā mea nui e synthesize i ka amonia, ka urea a me ka ʻeleʻele kalapona. Hiki ke hoʻohana ʻia e hana i ka methanol, hydrogen, acetylene, ethylene, formaldehyde, carbon disulfide, nitromethane, hydrocyanic acid a me 1,4-butanediol. Hiki i ka chlorination o ka methane ke hana i ka mono-, di-, trichloromethane a me carbon tetrachloride. E kūʻai i loko o kahi hale kūʻai maʻalili. E mālama i ke ahi a me nā kumu wela. ʻAʻole pono ka mahana o ka mālama ʻana ma mua o 30 ° C. Pono e hoʻokaʻawale ʻia mai nā oxidants, etc., a ʻaʻole pono e hui pū ʻia. E hoʻohana i nā kukui pahū a me nā keʻena ea. ʻAʻole ʻae ʻia ka hoʻohana ʻana i nā mea hana mechanical a me nā mea hana e maʻalahi i nā huna ahi. Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia. He pōʻino paha ka methane i ke kaiapuni, a pono e nānā pono i nā iʻa a me nā kino wai. Pono e nānā nui i ka haumia o ka wai ma luna, ka lepo, ka lewa a me ka wai inu.

Noi:

①Ma ke ʻano he wahie

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

②Ma ka ʻoihana Kemika

Hoʻololi ʻia ka Methane i ke kinoea synthesis, kahi hui o ka carbon monoxide a me ka hydrogen, ma o ka hoʻoponopono ʻana i ka mahu.

Pūʻolo maʻamau:

Pōmaikaʻi:

①Maʻemaʻe kiʻekiʻe, hale hana hou loa;

②Ka mea hana palapala ISO;

③Hoʻouna wikiwiki;

④Stable maka waiwai mai loko mai;

⑤ ʻO ka ʻōnaehana hoʻopaʻa inoa pūnaewele no ka hoʻokele maikaʻi ʻana i kēlā me kēia pae;

⑥Ke koi kiʻekiʻe a me ke kaʻina hana no ka mālama ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;
