Methane'ā

Methane mea he gaseous Nine Inch hui me ka Nine Inch haʻilula CH4. 'O kēia ka simplest Luna o alkanes. Other inoa no keia pae ana o ke aloha i huiʻia: ke kaupalenaʻana, paʻa kūhohonu loa paha paraffinic hydrocarbons. Ka mea, i wehewehe aku e loaa he hookahi hoopaa ma waena o kalapona nā'ātoma i loko o ka lātoma, a pau valences ke koe ana o kela a me keia o ka kalapona nā'ātoma i paʻa kūhohonu loa ma ka hydrogen nā'ātoma. No ka alkanes ka mea nui loa naoh o ke ahi. Ka mea kuni i ka mea e lilo o carbon dioxide kinoea a me ka wai ka ohu. E like me ka hopena, he nui nui o ka hookuu Nine Inch ikehu, a ua hoohuliia mai i ka wela a me ka uila ikehu. Methane mea flammable wai, a me ka papa kuhikuhiE ke keʻena o maoli kinoea, aʻo ia ka hale kalapu no wahie. Ma ka naau o ka lehulehu i ka maoli wāwahie naoh mea methane'ā. No ka mea, o lalo o maʻamau rula mea he kinoea, ia mea paakiki e lawe aku ma luna o mamao loa mai ke kumu, pela no ia mea pinepine mālama '-liquefied.

Ke'ā kaʻina hana o ka naoh ma waena o methane a me ka oxygen, a laila i loko o ka simplest alkane'okesaside. Kēia produces kalapona'okikene lua, ka wai, a me ka puu o ka ikehu. hiki ke ho'ākāka 'ia ma'ā o methane ma ka helu kaulike: CH4 [kinoea] + 2O2 [kinoea] → CO2 [kinoea] + 2H2O [mahu] + 891 kJ. Oia hoi, kekahi lātoma o methane ma ka naoh me nā nā lātoma o ka o oxygen ano he lātoma o ke kalapona'okikene lua a me nā nā lātoma wai. Ua hookuu aku oia i ka wela ikehu, i mea like me 891 kJ. Natural kinoea o ka maemae no ke ahi no laila, e like me ka lanahu, ka aila a me nā mōʻalihaku e oi luna 'ma ka haku mele' ana wāwahie. No laila, i'ā ka mea, hoʻokuʻu akula i loko o ka lewa okoa nā palapala Nine Inch. No maoli kinoeaʻano nui haku o ka methane (ma kahi o 95%), a laila, e aa ana ka apuepue ia produces ma-huahana a me kā lākou mau 'ana e haʻalele i oi aku ka li ma ka hihia o nā mōʻalihaku.

Ke calorific waiwai o ka methane (55.7 kJ / g) Uaʻoi kona kiʻekiʻe ma mua o kona homologues, e like me ethane (51.9 kJ / g), propane (50.35 kJ / g), butane (49.50 kJ / g), a 'ē aʻe mōʻalihaku (laau, lanahu, kerosene). Ke ahi methane produces hou ikehu. E hoomakaukau no ka makahiki Incandescent 100 W malamalama pu u kukui pono kuni i ka mea hana 260 kg o ka laau, a me 120 kg o ka lanahu, kerosene paha 73,3 kg, 58 kg a me nā mea a pau o ka methane, a hoʻopili like me 78,8 m³ o maoli kinoea.

Ke simplest alkane mea nui i nā kumu waiwai i no ka uila hanauna. Kēia ia lŘlŘ ma ke ahi ia e like me ka wahie ieoaeunoai, hoʻomakaʻia mahu a kipaku i ka mahu mīkini peahi uila. I ka methane'ā ua hoʻohana 'ia e paka wela flue kinoea, nona ka ikehu mau hiʻohiʻona nō ana o ke kinoea mīkini peahi uila ('ā ke hoʻohana a ka mīkini peahi uila a me ka mīkini peahi uila hoʻi). Ma na kulanakauhale he nui, methane ua hookiokio i home no wahi lulu hahana maoli nō kēia a me ka imu. Ke hoʻohālikelike a me nā 'ano o ka hydrocarbon wahie umu ahi maoli kinoea mai ka uuku evolution o ke kalapona'okikene lua, a me ka nui nui o ka ua loaʻa wela.

'ā o ka methane ua hoʻohana 'ia e hoʻokō kiʻekiʻe mahana ma ka umu o ka likeʻole Nine Inch na hana, no ka laʻana, nui-'etolina mea kanu. Na maoli kinoea i hui pūʻia me ka lewa a pau loa, a hiki i ka burners o ka pyrolysis kapuahi. Ke'ā kaʻina hana paha ke flue kinoea me kiʻekiʻe wela (700-900 ° C). Ka mea, hoʻa'ā i paipu (aia i loko o ka umu ahi,) i ka i maka mea läÿau, ua hanaiia me ka mahu (ma ka mea e ho'ēmi i Coke ho okumu i loko o ka umu ahi paipu). Ma lalo o ka hana o ka kiʻekiʻe mahana, i ka ai iiiaanoaa o Nine Inch reactions, a e hoohua mai i ka pale umauma hoʻokahi eiiiiiaiou ('etolina a me ka propylene), a he hopena ia (kēpau kaumaha pyrolysis, hydrogen a me ka methane hapa, ethane, propane, hydrocarbons, C4, C5, pyrocondensate; kēlā o ia i kona noi no ka laʻana, pyrocondensate hoʻohana i ka paka benzene a Hawaii kakolina eiiiiiaiou).

'ā o ka methane mea he luna 'physical-Nine Inch kŰia ma muli o ka exothermic redox naoh, wehewehe aku ma ke kiʻekiʻe pele ana a me ka hoʻokuʻu alahula mau dala o ka wela, a me ka wela hoolilo a me ka nuipa a hoolilo keʻano o ka hanaʻana. Nolaila, o ka manao i ka ho'ākāka 'ukuhiia'ā ka mahana o ka paakiki hana, mai ma ka hou ana i ka haku mele' ana o ka wahie ukuhiia ikaika ho ololi i kona puʻe a me ka loiloi mua ana wela. Ka mea, malama i ka hua o ka'ā mahana ala a me ka wela hoolilo a me ka nuipa a hoolilo keʻano o ka hanaʻana he hoʻonui i kona ka ho'ēmiʻana. Methane'ā ana wela i loko o ka manao keʻano o ka hanaʻana, a apparatuses Nine Inch? Iecaianoaaiiuo nānā 'ana i ka ho omaulia, a me ka na nā mea hoʻonoho (e laʻa me, i loko o ka umu pyrolysis), ka mea, ua anaia mai ka hoʻohana' ana thermocouples.
