I-Methane (CH4)

Amapharamitha obuchwepheshe

I-Methane iyinhlanganisela yezinto eziphilayo enefomula yama-molecule engu-CH4 kanye nesisindo sama-molecule esingu-16.043. I-Methane iyinto elula kakhulu yezinto eziphilayo kanye ne-hydrocarbon enokuqukethwe okuncane kakhulu kwekhabhoni (okuqukethwe okukhulu kakhulu kwe-hydrogen). I-Methane isakazeke kabanzi emvelweni futhi iyisakhi esiyinhloko segesi yemvelo, i-biogas, igesi yomgodi, njll., eyaziwa kakhulu ngokuthi igesi. I-Methane iyigesi engenambala futhi engenaphunga ngaphansi kwezimo ezijwayelekile. Ngaphansi kwezimo ezivamile, i-methane izinzile futhi kunzima kakhulu ukuyincibilikisa emanzini. Ayisabelani nama-oxidant aqinile njenge-potassium permanganate, futhi ayisabelani nama-acid aqinile noma ama-alkali. Kodwa ngaphansi kwezimo ezithile, i-methane nayo ibhekana nokusabela okuthile. I-Methane inguphethiloli obaluleke kakhulu. Iyisakhi esiyinhloko segesi yemvelo, ebalelwa cishe ku-87%. Iphinde isetshenziswe njengophethiloli ojwayelekile wama-heater amanzi kanye nezitofu zegesi zokuhlola inani lama-calories. I-Methane ingasetshenziswa njengegesi ejwayelekile kanye negesi yokulinganisa ukukhiqizwa kwama-alamu egesi avuthayo. Ingasetshenziswa futhi njengomthombo wekhabhoni wamaseli elanga, i-silicon film vapor chemical deposition, kanye nezinto zokusetshenziswa zokwenziwa kwemithi namakhemikhali. I-Methane isetshenziswa ngobuningi obukhulu ukuhlanganisa i-ammonia, i-urea kanye ne-carbon black. Ingasetshenziswa futhi ukukhiqiza i-methanol, i-hydrogen, i-acetylene, i-ethylene, i-formaldehyde, i-carbon disulfide, i-nitromethane, i-hydrocyanic acid kanye ne-1,4-butanediol. I-chlorine ye-methane ingakhiqiza i-mono-, i-di-, i-trichloromethane kanye ne-carbon tetrachloride. Gcina endaweni yokugcina epholile, enomoya. Gcina kude nomlilo kanye nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Kufanele igcinwe ngokwehlukana nama-oxidants, njll., futhi akufanele ixutshwe. Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya. Akuvunyelwe ukusebenzisa imishini yemishini namathuluzi avame ukuba nezinhlansi. Indawo yokugcina kufanele ifakwe imishini yokwelapha ephuthumayo evuzayo. I-Methane ingaba yingozi emvelweni, futhi kufanele kunakwe ngokukhethekile izinhlanzi kanye nezindawo zamanzi. Kufanele futhi kuqashelwe ngokukhethekile ukungcola kwamanzi angaphezulu, inhlabathi, umkhathi kanye namanzi okuphuza.

Isicelo:

①Njengophethiloli

I-Methane isetshenziswa njengophethiloli kuma-oven, emakhaya, kuma-water heater, kuma-oven, ezimotweni, kuma-turbine, nakwezinye izinto. Ivutha nomoya-mpilo ukuze idale umlilo.

②Embonini Yamakhemikhali

I-Methane iguqulwa ibe yigesi yokwenziwa, ingxube ye-carbon monoxide ne-hydrogen, ngokuguqulwa komusi.

Iphakheji evamile:

Inzuzo:

①Ubumsulwa obuphezulu, indawo yakamuva;

②Umkhiqizi wesitifiketi se-ISO;

③Ukulethwa okusheshayo;

④Izinto zokusetshenziswa eziqinile ezivela ekuhlinzekweni kwangaphakathi;

⑤Uhlelo lokuhlaziya oluku-inthanethi lokulawula ikhwalithi kuzo zonke izinyathelo;

⑥Isidingo esiphezulu kanye nenqubo ecophelelayo yokuphatha isilinda ngaphambi kokugcwalisa;
