Methane ikemikari inosanganiswa nekemikari formula CH4 (atomu imwe yecarbon uye maatomu mana ehydrogen).

Product Sumo

Methane ikemikari inosanganiswa nekemikari formula CH4 (atomu imwe yecarbon uye maatomu mana ehydrogen). Iboka-14 hydride uye iri nyore alkane, uye ndiyo huru inoumba gasi rechisikigo. Hurukuro hwemethane paNyika hunoita kuti ive mafuta anoyevedza, kunyangwe kuibata nekuichengeta kunopa matambudziko nekuda kwegasi rayo pasi pemamiriro akajairwa ekupisa nekumanikidza.
Natural methane inowanikwa zvose pasi pevhu uye pasi pepasi pegungwa. Kana yasvika pamusoro uye mumhepo, inozivikanwa seatmospheric methane. Mamiriro emuchadenga methane yePasi akawedzera nezvikamu zana nemakumi mashanu kubva muzana kubva muna 1750, uye inotora chikamu che20% chekumanikidza kwemwaranzi kubva kune ese akararama kwenguva refu uye akasanganiswa pasi rose magasi egreenhouse.

Application

Semafuta
Methane inoshandiswa sehuni dzehovhoni, dzimba, zvidziva zvemvura, hovhoni, motokari, maturbine, nezvimwe zvinhu. Inopisa neokisijeni kugadzira moto.

Mune Chemical Indasitiri
Methane inoshandurwa tosynthesis gasi, musanganiswa wecarbon monoxide nehydrogen, nekugadzirisa chiutsi.

Uses

Methane inoshandiswa mumaindasitiri emakemikari maitiro uye inogona kutakurwa semvura ine firiji (liquefied natural gas, kana LNG). Nepo kudonhedza kubva mumudziyo wemvura mufiriji kunotanga kurema kupfuura mhepo nekuda kwekuwedzera kuwanda kwegasi rinotonhora, gasi riri paambient tembiricha rakareruka kupfuura mweya. Mapaipi egasi anogovera huwandu hukuru hwegasi rechisikigo, iyo methane ndiyo chikamu chikuru.

1.Fuel
Methane inoshandiswa sehuni dzehovhoni, dzimba, zvidziva zvemvura, honi, mota, maturbine, nezvimwe zvinhu. Inopisa neokisijeni kugadzira kupisa.

2.Gasi rechisikigo
Methane yakakosha pakugadzira magetsi nekuipisa sehuni muturbine yegasi kana gwenya remagetsi. Kuenzaniswa nemamwe mafuta ehydrocarbon, methane inogadzira kabhoni dhaikisaidhi shoma kune imwe neimwe unit yekupisa inoburitswa. Panenge pa891 kJ/mol, kupisa kwemethane kunopisa kwakadzikira kupfuura chero imwe hydrocarbon asi chiyero chekupisa kwekupisa (891 kJ/mol) kune molecular mass (16.0 g/mol, iyo 12.0 g/mol icarbon) inoratidza kuti methane, iri iyo hydrocarbon yakapfava, inogadzira kupisa kwakawanda pahuwandu hwechikamu (55.7 kJ/g) kupfuura mamwe mahydrocarbon akaoma. Mumaguta akawanda, methane inopinzwa mudzimba kuti dzidziye uye kubika. Muchirevo chechinyorwa chino inowanzo zivikanwa segasi rechisikigo, iro rinoonekwa seine simba rinosvika 39 megajoules pa cubic meter, kana 1,000 BTU per standard cubic foot.

Methane iri muchimiro chegasi rakatsikirirwa rinoshandiswa sehuni yemotokari uye inonzi inochengetedza zvakatipoteredza kupfuura mamwe mafuta ezvicherwa akaita sepeturu/peturu nedhiziri.Ongororo pamusoro penzira dzeadsorption yekuchengetera methane kuti ishandiswe semafuta emotokari yakaitwa. .

3.Liquefied gasi rechisikigo
Liquefied natural gas (LNG) igasi rechisikigo (kunyanya methane, CH4) rakashandurwa kuita liquid form kuti ive nyore kuchengeta kana kutakura.Matangi eLNG anodhura anodiwa kutakura methane.

Liquefied gasi rinogara rinenge 1/600th vhoriyamu yegasi rechisikigo munzvimbo ine gasi. Haina hwema, haina ruvara, haina chepfu uye haina-corrosive. Njodzi dzinosanganisira kupisa mushure mekuputika mumhepo ine gasi, kutonhora, uye asphyxia.

4.Liquid-methane rocket fuel
Methane yemvura yakanatswa inoshandiswa semafuta e rocket.Methane inonzi inopa mukana pane parafini yekuisa kabhoni shoma panhengo dzemukati dzemaroketi, zvichideredza kuoma kwekushandisazve mabooster.

Methane yakawanda munzvimbo dzakawanda dzeSolar system uye inogona kukohwa pamusoro peimwe solar-system body (kunyanya, kushandisa methane kugadzirwa kubva mumidziyo yemuno inowanikwa paMars kana Titan), ichipa mafuta erwendo rwekudzoka.

5.Chemical feedstock
Methane inoshandurwa kuita gasi rekugadzira, musanganiswa wecarbon monoxide nehydrogen, nekugadzirisa chiutsi. Iyi endergonic process (inoda simba) inoshandisa zvinokonzeresa uye inoda kupisa kwakanyanya, kutenderedza 700-1100 °C.

Extraterrestrial methane
Methane yaonekwa kana kuti inofungidzirwa kuti iripo pamapuraneti ese esolar system uye yakawanda yemwedzi mikuru. Nekugoneka kunze kweMars, inofungidzirwa kuti yakabva kune abiotic maitiro.
Methane (CH4) paMars - inogona kuwanikwa uye kunyura.
Methane yakakurudzirwa kuti igone kufambisa zvitundumuseremusere pamisheni yeMars yeramangwana nekuda kwechimwe chikamu chekugona kuigadzira pasirese nekushandiswa kwezviwanikwa.[58] Kugadziriswa kweSabatier methanation reaction inogona kushandiswa nemubhedha wakavhenganiswa wekukonzeresa uye kuchinjika kwemvura-gasi mune imwe reactor kugadzira methane kubva kune yakasvibirira inowanikwa paMars, uchishandisa mvura kubva pasi peMartian uye kabhoni dhaikisaidhi mumhepo yeMartian. .

Methane inogona kugadzirwa nenzira isiri yebhayoloji inonzi ''serpentinization[a] inosanganisira mvura, carbon dioxide, uye mineral olivine, iyo inozivikanwa kuva inowanikwa paMars.
