Inkcazo kunye neMigangatho yokuHlanzeka koBumsulwa obuPhezuluIMethane

Ubunyulu obuphezului-methaneibhekisa kwigesi ye-methane enobunyulu obuphezulu. Ngokubanzi, i-methane enobunyulu obuyi-99.99% nangaphezulu inokuthathwa njengobunyulu obuphezului-methaneKwezinye iinkqubo ezingqongqo ngakumbi, ezifana neshishini le-elektroniki, iimfuno zobumsulwa zinokufikelela kwi-99.999% nangaphezulu. Olu bumsulwa buphezulu lufezekiswa ngokusebenzisa ubuchwepheshe obuntsonkothileyo bokucoca igesi kunye nokwahlulahlula ukususa ukungcola okufana nokufuma, i-carbon dioxide, i-carbon monoxide, i-hydrogen, kunye nezinye izinto zegesi.

Iindawo zokusetyenziswa kwe-methane ecocekileyo kakhulu

Kwishishini le-elektroniki,i-methane ecocekileyo kakhuluisetyenziswa njengegesi yokugrumba kunye nezinto eziluhlaza zokufaka umphunga wamakhemikhali (CVD) kwimveliso ye-semiconductor. Umzekelo, ekugrumbeni kwe-plasma, i-methane ixutywa nezinye iigesi ukuze igrumbe ngokuchanekileyo izinto ze-semiconductor, zenze iipateni ezincinci zesekethe. Kwi-CVD,i-methaneibonelela ngomthombo wekhabhoni wokukhulisa iifilimu ezincinci ezisekelwe kwikhabhoni, ezifana neefilimu ze-silicon carbide, ezidlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nokuzinza kwezixhobo ze-semiconductor.

Izinto ezisetyenziswa kwiikhemikhali:I-methane ecocekileyo kakhulusisixhobo esibalulekileyo sokwenziwa kweekhemikhali ezininzi ezinexabiso eliphezulu. Umzekelo, ingasabela kunye ne-chlorine ukuvelisa iikhompawundi ze-chloromethane ezifana ne-chloroform, i-dichloromethane, i-trichloromethane, kunye ne-carbon tetrachloride. I-chloromethane sisixhobo sokwenziwa kweekhompawundi ze-organosilicon, i-dichloromethane kunye ne-trichloromethane zisetyenziswa kakhulu njengezinyibilikisi, kwaye i-carbon tetrachloride yayikhe yasetyenziswa njenge-arhente yokucima umlilo, kodwa ukusetyenziswa kwayo ngoku kunqunyelwe kakhulu ngenxa yeziphumo zayo zokunciphisa i-ozone. Ngaphezu koko,i-methaneinokuguqulwa ibe yi-syngas (umxube we-carbon monoxide kunye ne-hydrogen) ngokusebenzisa ii-reforming reactions, kwaye i-syngas sisixhobo esisisiseko sokuvelisa i-methanol, i-synthetic ammonia, kunye nezinye iimveliso ezininzi zeekhemikhali.

Kwicandelo lamandla: Nangona i-methane eqhelekileyo (igesi yendalo) ingumthombo wamandla oyintloko,i-methane ecocekileyo kakhuluikwadlala indima kwizicelo ezithile zamandla ezikhethekileyo. Umzekelo, kwiiseli zamafutha, i-methane ecocekileyo kakhulu ingasetyenziswa njengepetroli, iguqulwa ukuze kuveliswe i-hydrogen, enika amandla iseli yamafutha. Xa kuthelekiswa namafutha emveli efosili, iiseli zamafutha ezisebenzisa i-methane ecocekileyo kakhulu zifumana amandla aphezulu kwaye zikhupha ungcoliseko oluphantsi.

Ukulungiswa kweegesi ezisemgangathweni:I-methane ecocekileyo kakhuluingasetyenziswa njengegesi eqhelekileyo yokulinganisa izixhobo zokuhlalutya igesi. Umzekelo, kwi-chromatograph yegesi, usebenzisai-methane ecocekileyo kakhuluigesi esemgangathweni yoxinaniso eyaziwayo inokulinganisa uvakalelo kunye nokuchaneka kwesixhobo, iqinisekise iziphumo zohlalutyo ezichanekileyo nezithembekileyo kwezinye iigesi.
