Kumenyekanisha ibicuruzwa

Methane ni imiti ivanze na formula ya chimique CH4 (atom imwe ya karubone na atome enye za hydrogen). Nitsinda-14 hydride na alkane yoroshye, kandi nikintu nyamukuru kigize gaze gasanzwe. Ubwinshi bwa metani ku isi ituma iba lisansi ishimishije, nubwo kuyifata no kuyibika bitera ibibazo bitewe na gaze ya gaze mubihe bisanzwe byubushyuhe nigitutu.
Methane isanzwe iboneka munsi yubutaka ndetse no munsi yinyanja. Iyo igeze hejuru nikirere, izwi nka metani yo mu kirere. Isi ya metani yo mu kirere yiyongereyeho hafi 150% kuva mu 1750, kandi ikaba ifite 20% by'ingufu zose zikomoka ku mirasire ya gaze ya parike imaze igihe kirekire kandi ivanze ku isi.

Gusaba

Nka lisansi
Methane ikoreshwa nka lisansi yitanura, ingo, ubushyuhe bwamazi, itanura, imodoka, turbine, nibindi bintu. Irashya hamwe na ogisijeni kugirango ikore umuriro.

Mu nganda zikora imiti
Methane ihindurwamo gaze ya tosynthesis, imvange ya monoxyde de carbone na hydrogen, muguhindura amavuta.

Gukoresha

Methane ikoreshwa mubikorwa bya chimique yinganda kandi irashobora gutwarwa nkamazi akonjesha (gaze naturel, cyangwa LNG). Mugihe imyanda ivuye mu kintu gikonjesha gikonjesha mu ikubitiro iremereye kuruta umwuka kubera ubwiyongere bwa gaze ikonje, gaze ku bushyuhe bw’ibidukikije iba yoroshye kuruta umwuka. Imiyoboro ya gaze ikwirakwiza gaze gasanzwe, muri yo metani ni cyo kintu cy'ingenzi.

1.Ibicanwa
Methane ikoreshwa nka lisansi yitanura, ingo, ubushyuhe bwamazi, itanura, imodoka, turbine, nibindi bintu. Irashya na ogisijeni kugirango itere ubushyuhe.

Gazi isanzwe
Methane ni ingenzi kubyara amashanyarazi uyitwika nka lisansi muri turbine ya gaze cyangwa moteri. Ugereranije n’ibindi bicanwa bya hydrocarubone, metani itanga dioxyde de carbone nkeya kuri buri gice cyubushyuhe bwarekuwe. Hafi ya 891 kJ / mol, ubushyuhe bwa metani yo gutwikwa buri munsi yizindi hydrocarubone ariko ikigereranyo cyubushyuhe bwo gutwikwa (891 kJ / mol) na misile ya molekile (16.0 g / mol, muri yo 12.0 g / mol ni karubone) yerekana ko metani, kuba hydrocarubone yoroshye, itanga ubushyuhe bwinshi kuri mass (55.7 kJ / g) kuruta andi mavuta ya hydrocarbone. Mu mijyi myinshi, metani ihindurwamo amazu yo gushyushya urugo no guteka. Ni muri urwo rwego ubusanzwe izwi nka gaze karemano, ifatwa nk’ingufu zingana na megajoules 39 kuri metero kibe, cyangwa BTU 1.000 kuri metero kibe isanzwe.

Methane muburyo bwa gaze gasanzwe ikoreshwa nkamavuta yimodoka kandi bivugwa ko yangiza ibidukikije kurusha ibindi bicanwa byamavuta nka lisansi / lisansi na mazutu. Shakisha uburyo bwa adsorption bwo kubika metani kugirango ikoreshwe nkibicanwa byimodoka. .

3.Gasi isanzwe
Gazi isanzwe (LNG) ni gaze karemano (yiganjemo metani, CH4) yahinduwe muburyo bwamazi kugirango byoroherezwe kubika cyangwa gutwara. Ibigega bya LNG bihenze birasabwa gutwara metani.

Gazi isanzwe yanduye ifata hafi 1/600 ingano ya gaze naturel muri leta ya gaze. Ntabwo ari impumuro nziza, idafite ibara, idafite uburozi kandi ntishobora kubora. Ibyago birimo gucanwa nyuma yo guhumeka muburyo bwa gaze, gukonja, na asphyxia.

4. Amavuta ya roketi ya metani
Methane itunganijwe neza ikoreshwa nka lisansi ya roketi. Bivugwa ko Methane itanga inyungu kurenza kerosene yo gushyira karubone nkeya ku gice cyimbere cya moteri ya roketi, bikagabanya ingorane zo kongera gukoresha bosters.

Methane ni nyinshi mu bice byinshi bigize izuba kandi birashoboka ko ishobora gusarurwa hejuru y’undi mubumbe w’izuba (cyane cyane, ukoresheje umusaruro wa metani ukomoka ku bikoresho byaho biboneka kuri Mars cyangwa Titan), bitanga lisansi y'urugendo rwo gutaha.

5.Ibiryo bya shimi
Methane ihindurwamo gaze ya synthesis, imvange ya monoxyde de carbone na hydrogen, muguhindura amavuta. Ubu buryo bwa endergonic (busaba ingufu) bukoresha catalizator kandi busaba ubushyuhe bwinshi, hafi 700–1100 ° C.

Ingamba zambere zubutabazi

Ijisho:Nta na kimwe gisabwa gaze. Niba hakonje ubukonje, oza amaso n'amazi akonje muminota 15 hanyuma uhite ubona ubuvuzi.
Uruhu:Ntanumwe wasabye kwibagirwa. Kugirango uhure na dermal cyangwa ukekwaho ubukonje, kura imyenda yanduye hanyuma usukure ahantu hafashwe n'amazi ashyushye ya luke.NTUKORESHE AMAZI Ashyushye.Umuganga agomba kubonana umurwayi bidatinze niba guhura nibicuruzwa byaviriyemo kubyimba hejuru ya dermal cyangwa mubukonje bwimbitse. .
Guhumeka:GUTEZA IMBERE ITANGAZAMAKURU MU BURYO BWO GUSHYIRA MU BIKORWA. GUKIZA UMUNTU UKWIYE GUKORESHWA HAMWE N'UMWUKA UFATANYIJWE NA APPARATUS. Abahitanwa no guhumeka neza bagomba gufashwa ahantu hatanduye no guhumeka umwuka mwiza. Niba guhumeka bigoye, koresha ogisijeni. Abantu batagira ubwenge bagomba kwimurirwa ahantu hadahumanye kandi, nibiba ngombwa, bakazura ibihimbano hamwe na ogisijeni yinyongera. Kuvura bigomba kuba ibimenyetso kandi bigashyigikirwa.

Methane yo hanze
Methane yatahuwe cyangwa ikekwa ko ibaho ku mibumbe yose y’izuba ndetse n’ukwezi kwinshi. Usibye bishoboka kuri Mars, byizerwa ko byaturutse mubikorwa bya abiotic.
Methane (CH4) kuri Mars - inkomoko ishobora no kurohama.
Methane yasabwe kuba icyogajuru gishobora kohereza mu butumwa bwa Mars mu gihe kizaza bitewe n’uko bishoboka ko cyayihuza ku isi hifashishijwe umutungo. [58] Guhindura imiterere ya metani ya Sabatier irashobora gukoreshwa hamwe nigitanda kivanze cya catalizator hamwe noguhindura amazi-gazi mumashanyarazi imwe kugirango habeho metani ivuye mubikoresho fatizo biboneka kuri Mars, ukoresheje amazi ava mubutaka bwa Marti na dioxyde de carbone mukirere cya Marti .

Methane irashobora gukorwa nuburyo butari ibinyabuzima bwitwa '' inzoka [a] irimo amazi, dioxyde de carbone, na minerval olivine, izwiho kuba kuri Mars.
