I-Methane (CH4)

Imingcele yezobuchwepheshe

I-Methane iyinhlanganisela ye-organic ene-molecular formula ye-CH4 kanye nesisindo se-molecular 16.043.I-Methane iwudaba olulula kunazo zonke kanye ne-hydrocarbon enokuqukethwe kwekhabhoni encane kakhulu (i-hydrogen enkulu kakhulu).I-Methane isatshalaliswa kabanzi endalweni futhi iyisakhi esiyinhloko segesi yemvelo, i-biogas, i-pit gas, njll., eyaziwa kakhulu ngokuthi igesi.I-Methane iyigesi engenambala futhi engenaphunga ngaphansi kwezimo ezijwayelekile.Ngaphansi kwezimo ezijwayelekile, i-methane izinzile futhi kunzima kakhulu ukuncibilika emanzini.Ayisabeli ngama-oxidants aqinile njenge-potassium permanganate, futhi ayisabela ngama-asidi aqinile noma ama-alkali.Kodwa ngaphansi kwezimo ezithile, i-methane nayo ibhekana nokusabela okuthile.I-Methane iyiphethiloli ebaluleke kakhulu.Iyingxenye eyinhloko yegesi yemvelo, elinganiselwa ku-87%.Iphinde isetshenziswe njengophethiloli ojwayelekile wezishisi zamanzi nezitofu zegesi zokuhlola inani lekhalori.I-Methane ingasetshenziswa njengegesi ejwayelekile kanye negesi yokulinganisa ukuze kukhiqizwe ama-alamu egesi avuthayo.Ingasetshenziswa futhi njengomthombo wekhabhoni wamaseli elanga, i-amorphous silicon film vapor chemical deposition, futhi njengempahla eluhlaza yokuhlanganiswa kwemithi namakhemikhali.I-methane iphinde isetshenziswe ngobuningi ukuhlanganisa i-ammonia, i-urea kanye ne-carbon black.Ingase futhi isetshenziselwe ukukhiqiza i-methanol, i-hydrogen, i-acetylene, i-ethylene, i-formaldehyde, i-carbon disulfide, i-nitromethane, i-hydrocyanic acid ne-1,4-butanediol.I-chlorination ye-methane ingakhiqiza i-mono-, i-di-, i-trichloromethane ne-carbon tetrachloride.Gcina endaweni epholile, engenisa umoya.Gcina kude nomlilo nemithombo yokushisa.Izinga lokushisa lokugcina akufanele lidlule ku-30°C.Kufanele igcinwe ngokuhlukana nama-oxidants, njll., futhi akufanele ihlanganiswe.Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.Akuvunyelwe ukusebenzisa imishini namathuluzi ajwayele ukuvela izinhlansi.Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.I-methane ingase ibe yingozi emvelweni, futhi ukunakekelwa okukhethekile kufanele kukhokhwe ezinhlanzini nasezindaweni zamanzi.Ukunakwa okukhethekile kufanele futhi kukhokhwe ekungcolisweni kwamanzi angaphezulu, inhlabathi, umkhathi namanzi okuphuza.

Isicelo:

①Njengesibaseli

I-methane isetshenziswa njengophethiloli ohovini, ezindlini, ezishisisa amanzi, eziko, ezimotweni, ezinjinini zomoya, nezinye izinto.Ishisa i-oxygen ukuze idale umlilo.

②Embonini Yamakhemikhali

I-Methane iguqulwa igesi ye-tosynthesis, ingxube ye-carbon monoxide ne-hydrogen, ngokuguqula umusi.

Iphakheji evamile:

Inzuzo:

①Ukuhlanzeka okuphezulu, indawo yakamuva;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Izinto ezingavuthiwe ezizinzile ezivela ekunikezeni kwangaphakathi;

⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;
