I-Methane iyindawo yamakhemikhali ngefomula yamakhemikhali CH4 (i-athomu elilodwa lekhabhoni nama-athomu amane we-hydrogen).

Isingeniso Somkhiqizo

I-Methane iyindawo yamakhemikhali ngefomula yamakhemikhali CH4 (i-athomu elilodwa lekhabhoni nama-athomu amane we-hydrogen). Kuyiqembu-14 hydride kanye ne-alkane elula kunazo zonke, futhi kuyisici esiyinhloko segesi yemvelo. Ukuchichima okuningi kwe-methane emhlabeni kwenza kube ngophethiloli obukekayo, noma ukuthwebula nokugcina kubeka izinselelo ngenxa yesimo sayo se-gaseous ngaphansi kwezimo ezijwayelekile zokushisa nokucindezela.
I-Methane yezemvelo itholakala ngezansi komhlabathi nangaphansi kolwandle. Lapho ifinyelela phezulu nasemkhathini, yaziwa njenge-methane ye-atmospheric. Ukuhlushwa komhlaba kwe-methane womhlaba kukhuphuke cishe ngo-150% kusukela ngo-1750, futhi kukhombisa ama-20% okuphoqelelwa okuphelele kokuphoqelela okuhlala kuwo wonke amagesi ahlanganisiwe nasemhlabeni jikelele.

Isicelo

Njengophethiloli
IMethane isetshenziswa njengophethiloli kuhhavini, amakhaya, ama-heather amanzi, ama-kilns, izimoto, izimoto, nezinye izinto. Kuhlanganisa umoya-mpilo ukudala umlilo.

Embonini yamakhemikhali
I-Methane iguqulwe i-tosynthesis igesi, ingxube ye-carbon monoxide ne-hydrogen, ngokuguqula umusi.

Sebenzisa

I-Methane isetshenziswa ezinhlelweni zamakhemikhali zezimboni futhi ingahanjiswa njengoketshezi oluqandisiwe (igesi yemvelo evuthayo, noma i-LNG). Ngenkathi ukuvuza kusuka esitsheni esiqandisiwe kuqale kunzima kunomoya ngenxa yobukhulu obukhulayo begesi ebandayo, igesi ekushiseni okukhona kulula kunomoya. Amapayipi kaphethiloli asabalalisa amanani amakhulu egesi yemvelo, okwakuyi-methane eyingxenye eyinhloko.

1.Fuel
IMethane isetshenziswa njengophethiloli kuhhavini, amakhaya, ama-heather amanzi, ama-kilns, izimoto, izimoto, nezinye izinto. Iphoqa nge-oksijini ukudala ukushisa.

2.
I-Methane ibalulekile ekuphephelweni ngugesi ngokuyishisa njengophethiloli e-turbine noma i-steam generator. Uma kuqhathaniswa namanye amafutha e-hydrocarbon, i-methane ikhiqiza i-carbon dioxide engaphansi kweyunithi ngalinye lokushisa elikhishwe. Cishe ngo-891 KJ / Mol, ukushisa kukaThethne kwe-combustion kuphansi kunanoma iyiphi enye i-hydrocarbon kodwa isilinganiso sokushisa kwe-comburc (i-16.0 g / mol, kukhiqizwa okungcono kwe-hydrobhoni (i-55.7 kJ / g) kunezinye eziyinkimbinkimbi hydrocarbons. Emadolobheni amaningi, i-methane ipakelwa emakhaya okushisa kwasekhaya nokupheka. Kulesi simo kuvame ukuthi kwaziwa ngokuthi igesi yemvelo, okubhekwa njengokuqukethwe kwamandla kwama-megajoules angama-39 ngamamitha ayi-39 nge-cubic metres, noma i-BTU eyi-1 000 nge-cubic unyawo olujwayelekile.

I-Methane ngendlela ecindezelwe igesi yemvelo ecindezelwe isetshenziswa njengophethiloli wemoto futhi ifuneka ukuthi inobungani bezemvelo kunamanye ama-petroline / petrol kanye ne-diesel.research ngezindlela ze-adsorption zesitoreji se-methane ukuze zisetshenziswe njengoba kusetshenzelwe izimoto.

3.Liqufied igesi yemvelo
I-Liquefied Mealight Gas (LNG) igesi yemvelo (i-methane ye-premane, i-CH4) eye yaguqulwa yaba yifomu le-Liquid ukuze kube lula ukugcinwa noma ukuthutha amathangi we-LNG.

Igesi yemvelo evulise ngayo cishe i-1/600 yomthamo wegesi yemvelo esifundazweni saseGaseous. Kuyinto engenamphundla, engenamibala, engeyona into enobuthi futhi ayinakuwohloka. Izingozi zifaka izingozi ngemuva komumo ku-gaporization esifundazweni sase-gaseous, iqhwa, kanye ne-askyxia.

I-4.liquiquid-Methane rocket uphethiloli
I-Refined liquid Metane isetshenziswa njenge-rocket fule.methane kubikwa ukuthi inikezela ngenzuzo ngaphezu kwe-carbon encane ezingxenyeni zangaphakathi ze-rocket motors, zinciphisa ubunzima bokusebenzisa kabusha ama-boosters.

I-Methane inala ezingxenyeni eziningi zohlelo lwelanga futhi kungenzeka ukuthi zivunwa phezu komunye umzimba wesistimu yelanga (ikakhulukazi, usebenzisa ukukhiqizwa kwe-methane kusuka ku-Mars noma iTitan), ukuhlinzeka ngophethiloli ohambweni lokubuya.

5.Chical Feedstock
IMethane iguqulwa i-synthesis igesi, ingxube ye-carbon monoxide ne-hydrogen, ngokuguqulwa kweSteam. Le nqubo ye-EnderGonic (edinga amandla) isebenzisa ama-catalysts futhi idinga amazinga okushisa aphezulu, cishe ngo-700-1100 ° C.

Izindlela Zomsizi Wokuqala

I-Eyecontact:Akukho okudingekayo igesi. Uma i-frostbite isolwa, amehlo amnandi ngamanzi apholile imizuzu engu-15 futhi athole ukunakekelwa kwezokwelashwa okusheshayo.
SkicContact:Ayikho imithelelo edingekayo. Okokuxhumana kwe-dermal noma ama-frostbite asolwa, asuse izingubo ezingcolisiwe kanye nezindawo ezithintekile ezinamanzi afudumele ngamanzi afudumele.
Inhalation:Ukunakwa kwezokwelapha okusheshayo kuyakhahla kuzo zonke izimo zokuphefumula ngokweqile. Abasebenzi abahlengi kufanele bahlome ngezinto zokuphefumula ezinazo. Izisulu zokuphefumula ezizaziyo kufanele zisize endaweni engangcoliswanga futhi zingena emoyeni omusha. Uma ukuphefumula kunzima, ukuphatha abantu abasebenza umoya-perygen.uncry kufanele kuhanjiswe endaweni engangcoliswanga futhi, njengoba kunesidingo, kunikezwe ukubhekelwa kabusha kokufakelwa kanye no-oksijini owengeziwe. Ukwelashwa kufanele kube okucacile futhi kusisekele.
Ukungena:Akukho ngaphansi kokusetshenziswa okujwayelekile.Tha kwezokwelapha uma kuvela izimpawu.
I-Notestophysician:Phatha ngokusobala.

I-methane ye-extraterrestrial
I-Methane itholakele noma kukholelwa ukuthi ikhona kuwo wonke amaplanethi ohlelo lwelanga kanye nezinyanga eziningi ezinkulu. Ngokuhlukile kwama-MARS, kukholakala ukuthi uqhamuka ezinqubweni ze-Abiotic.
I-Methane (CH4) kwiMars - imithombo engaba khona kanye nokucwila.
IMethane iphakanyisiwe njenge-rocket profelant okungenzeka kuma-Mars arvions angenayo engxenyeni yokuthi kungenzeka ukuthi ahlukane nalo emhlabeni ngokusetshenziswa kwezinsizakusebenza. [58] Ukuzivumelanisa nezimo zeSabatier Methanation Reaction kungasetshenziswa ngombhede omkhulu ohlanganisiwe kanye nokushintshwa kwamanzi okubuyiswayo ku-metane eyodwa ukukhiqiza i-methane kusuka kuma-mars atholakalayo kuMartian kanye ne-Carbon Dioxide esimweni seMartian.

IMethane ingakhiqizwa yinqubo engeyona eyebhayoloji ebizwa ngokuthi '' inyoka [a] ibandakanya amanzi, isikhutha, kanye ne-mineral Olivine, eyaziwa ukuthi ijwayelekile kuma-Mars.
