Intshayelelo Intshayelelo

I-methane yindawo yemichiza enefomula yekhemikhali ch4 (i-atom enye yekhabhoni kunye neeathom ezine ze-hydrogen). Liqela le-Hydride le-14 kunye ne-alkane elula, kwaye yeyona ndawo iphambili kwigesi yendalo. Intabalala ye-methane emhlabeni yenza ipetroli, nangona ifake i-itsing kwaye igcina imiceli mngeni ngenxa yendawo yayo yegesi phantsi kweemeko eziqhelekileyo zobushushu kunye noxinzelelo.
I-methane yendalo ifunyanwa ngezantsi komhlaba kwaye phantsi komgangatho wolwandle. Xa ifikelela kumphezulu kunye nemozulu, yaziwa ngokuba yi-thathane ye-thathane. Ukugxininiswa kwe-methane yomhlaba inyuke nge-150% ukusukela nge-1750, kwaye inika ingxelo engama-20% ye-radi eyanyanzela iphela kwaye ixutywe negesi eluhlaza okwesibhakabhaka.

Isicelo

Njengamafutha
I-Methane isetyenziswa njenge-oveni ye-oveni, amakhaya, izitshisi zamanzi, iikhilomitha, iimoto, iiturbines, kunye nezinye izinto. Idibene neoksijini yokwenza umlilo.

Kwicandelo lekhemikhali
I-Methane iguqulwe irhasi ye-tosynthesis, umxube we-carbon monoxide kunye ne-hydrogen, ngokuguqula i-Steam.

Isebenzisa

I-Methane isetyenziswa kwiipali zemichiza yemizi-mveliso kwaye inokuhanjiswa njengolwelo olunefriji (irhasi yendalo etyhutyhakeleyo, okanye i-LNG). Ngelixa kuvuza kwisikhongozeli kulwelo olunesidima kunomoya onzima kunomoya ngenxa yoxinzelelo lwegesi ebandayo, irhasi kubushushu obufanelekileyo kulula kunomoya. Imibhobho yegesi ihambisa izixa ezikhulu zerhasi yendalo, apho i-methane licandelo eliyintloko.

1.Fuleni
I-Methane isetyenziswa njenge-oveni ye-oveni, amakhaya, izitshisi zamanzi, iikhilomitha, iimoto, iiturbines, kunye nezinye izinto. Idibene neoksijini yokwenza ubushushu.

Igesi yegesi
I-methane ibalulekile ekuveliseni umbane ngokutshisa njengeoyile kwi-tuels kwi-turbine yegesi okanye umveli weSteam. Xa kuthelekiswa nezinye i-fuelsbon ye-hydrocarn, i-methane ivelisa i-carbon dioxide encinci kwicandelo ngalinye lobushushu likhutshiwe. Malunga ne-891 kj / mol, ubushushu be-methane ye-quardlotion iphantsi kunenye i-hydrocarbon kodwa i-fydrocarbon enobushushu (i-8,0 g / mol) kwiyunithi nganye (55.7 kj / g) kunenye I-Hydrocarbons enzima. Kwizixeko ezininzi, iMethane ifakwe kumakhaya okufudumeza ekhaya nokupheka. Kule meko ihlala yaziwa njengegesi yendalo, ethathwa njengezakhono ze-39 megajoueles ngemitha nganye, okanye i-1 000 ye-BTU inyawo.

I-methane ngendlela yegesi yendalo isetyenziswa njengepetroli yemoto kwaye ibango inobuhlobo kuneminye indlela yokugcina i-adthane egciniweyo.

3.Liqueffihlo yeNdalo
Irhasi yendalo eqingqiweyo (i-LNG) yirhasi yendalo (i-Tratthane yendalo, i-Ch4) eguqulwe ibe yifom yolwelo ukuba ilula ukugcinwa okanye ukuthutha i-LNG inyanzelekile ukuba ithutho i-methane.

Igesi yendalo yendalo ihlala malunga ne-1/600 yerhasi yegesi yendalo kwimeko yegesi. Yinto engekhoyo, engenabala, engenatyhefu kwaye engabinayo. Iingozi zibandakanya ukuvutha umlilo emva kokutshona kwendawo yendawo, ukukhululeka, kunye ne-asphyxia.

4.Lidid-Methane Roocket ipetroli
I-methane yolwelo oluhlaziyiweyo isetyenziswa njenge-rocket funa i-rocket fuel.methane ixelwe ukuba inikezele nge-kerosene ye-ribhon ye-rocket kwi-rocket mootors, ukunciphisa ubunzima bokuphinda-phinda i-boosters.

I-Methane ininzi kwiindawo ezininzi zeSolar System kwaye inokubangela ukuba ivunwe kumphezulu welinye inkqubo ye-solar (ngakumbi, isebenzisa imveliso ye-solar ukusuka kwi-Mars okanye iTitan), ibonelela nge-oyile kuhambo lokubuya.

5.Chemical Firetock
I-Methane iguqulwa kwigesi yeSynthesi, umxube we-carbon monoxide kunye ne-hydrogen, ngokuguqula i-Steam. Le nkqubo yokufikelela emveni (efuna amandla) isebenzisa i-catalysts kwaye ifuna ubushushu obuphezulu, malunga ne-700-10 ° C.

Amanyathelo okuqala oncedo

Uqhagamshelo lamehlo:Akukho namnye ufuna igesi. Ukuba i-rostbite ikrokrelwe, ibuhlungu ngamanzi apholileyo kangangemizuzu eli-15 kwaye ufumane ingqalelo kwangoko.
Ulusu:Akukho namnye ofunwayo. Ukudibana kwe-Dermal okanye i-rostbite ye-rostbite, susa impahla engcolileyo kwaye ichaphazele iindawo ezichaphazelekayo uLuka.
Ukuphefumla:Ukucofa ngokukhawuleza kwezonyango kuyahambelana nazo zonke iimeko zokuphefumla. Abasebenzi abahlangulayo kufuneka baxhotyiswe ngesixhobo sokuphefumla esinezixhobo. Amaxhoba okuphefumla abaceneyo kufuneka ancediswe kwindawo engafakwanga kwaye ansule umoya omtsha. Ukuba ukuphefumla kunzima, ukulawula abantu i-oxyn.unction abantu kufuneka bafudukele kwindawo engacocekanga kwaye, njengoko kufuneka, ngenxa yokuhlaziywa kwangaphambili kunye neoksijini eyongezelelweyo. Unyango kufuneka lube luphawu kwaye luxhasa.
I-INVENS:Akukho nto iphantsi kokusetyenziswa okuqhelekileyo.tlethi ngonyango ukuba iimpawu zenzeka.
Ubnowstophysicicicicia:Phatha uphawu.

I-Totthane
I-methane ifunyenwe okanye ikholelwe ukuba ifumaneka kuzo zonke iiplanethi zeSolar kwaye uninzi lwenyanga enkulu. Ngaphandle kokuphela kweMars, kukholelwa ukuba ivela kwiinkqubo ze-abiotic.
I-Methane (Ch4) kwi-Mars-imithombo enokubakho kunye nokuntywila.
I-methane icetywe njenge-rocket ye-rocket kwiprodlion ye-rooting yexesha elizayo ngenxa yenxalenye yokuyiqhelanisa kwiplanethi yesikhombisi. [58] Ukulungelelaniswa kwendlela yokuphendula yaseSabatier Inokusetyenziswa ngebhedi exubeneyo kunye nokubuyela umva kwegesi yaManzi kwi-ractor enye ukuvelisa i-Mars, ukusebenzisa amanzi kwi-Marbon kunye nekharbon kwi-Artian Admosfere.

I-methane inokuveliswa yinkqubo engeyiyo eyebhayoloji ebizwa ngokuba yi '' inyoka [i-carbon diokside, kunye ne-mineral of mineral, eyaziwayo ukuba ixhaphake kwi-Mars.
