Okuqhubekayoisilinganiso sokuhlushwa kwe-methanolibaluleke kakhulu ekukhiqizweni kwe-direct methanol fuel cell (DMFC), ikakhulukazi ekuthuthukiseni ukusebenza kahle kokuphehla ugesi kanye nokwelulwa kwempilo yebhethri. Ukusebenza kahle kokukhiqizwa kwamandla kunqunywa izinga lokusabela kwe-oxidation le-methanol endaweni ye-electrode, futhi izinga lokusabela kwe-oxidation lithonywa ukugxiliswa kwe-methanol kakhulu.
Ukuhlanganiswa okunembile kwesixazululo se-methanol kuyisidingo sokusabela okusebenzayo kwe-electrochemical kanye nokudluliswa kwama-electron abushelelezi. Ngaphezu kwalokho, iqinisekisa amandla kagesi aphezulu kanye nokuminyana kwamanje, ekugcineni ithuthukise ukusebenza kahle kokuguqulwa kwamandla. Ukukhipha amandla okuzinzile kungesinye isizathu sokulawula okunembile kokugxiliswa kwe-methanol. Ukukhipha amandla ahlukahlukene kuwumphumela wokuguquguquka kokugxiliswa kwe-methanol. I-Lonnmeterimitha yokuhlushwa ye-methanolingenye yamageji angcono kakhulu okubona ukugcwala kwe-methanol ngesikhathi sangempela, okubaluleke kakhulu kulayini wokukhiqiza we-automation.
Izindlela Zokulinganisa Zokugxilisa I-Methanol
No.1 Ukulinganiswa Kokuminyana
Aukuminyana imitha for uketsheziisebenzisa ukuhlobana phakathi kokuminyana nokugxila kwesisombululo se-methanol ukuze kuqashwe ukuqapha okuqhubekayo kokugxilwa kwe-methanol. Ukufaneleka kwale ndlela kulele esilinganisweni esilinganiselwe esizinzile kanye nokunemba okuphezulu ngokuya ngemodeli yobudlelwano bokuminyana nokugxilwa kwezinga lokushisa elisethiwe. Xhumana nonjiniyela bethu ukuthola eminye imininingwane mayelana neimitha yokuminyana kwebhethriemugqeni.
No.2 Indlela ye-Refractive
Ukugxiliswa kwesisombululo se-methanol kungase kuchazwe nge-inlinei-densitometernomai-refractometerngokusekelwe kumehluko wezinkomba ze-refractive phakathi kwe-methanol ne-solvent yayo. Nakuba kulula ukuyisebenzisa futhi inikeza impendulo esheshayo, inkomba ye-refractive iyahlukahluka kumazinga okushisa ahlukene. Ngakho-ke, ukulungiswa kwezinga lokushisa kuyadingeka ukuze kulinganiswe okunembile.
No.3 Near-Infrared Spectroscopy (NIR)
I-spectrometer eseduze ne-infrared isebenza kumodeli yobudlelwane bobuningi phakathi kokumunca nokugxilisa i-methanol, senza ukuskena kwesikhathi sangempela kwesisombululo se-methanol kanye nokulinganisa ukumunca ngamaza amaza athile. Ngokuvamile, i-methanol ibonisa iziqongo ezithile zokumunca ngaphakathi kwesifunda se-spectral esiseduze ne-infrared.
No.4 Inzwa ye-Electrochemical
Inzwa ye-electrochemical ithola ukugxila kwe-methanol ngoshintsho ekuncishisweni kwamanje noma okungaba khona kwe-oxidation endaweni. Inika amandla ukuqapha okuku-inthanethi kwesikhathi sangempela ngezindleko eziphansi zokuphendula ngokushesha, ukuzwela okuphezulu kanye nokukhetha okuhle. Noma kunjalo, ukuzinza kanye neminyaka yokuphila kusengozini yokungcola kanye nezinguquko zemvelo. Isebenza ngokujwayelekile kuphela ngokulinganiswa okuvamile nokushintshwa.
No.5 Fuel Cell
Ukugxiliswa kwe-methanol kuyakwazi ukutholwa kusukela kumandla wamanje kanye nokukhiqiza amandla kagesi ngeseli elikhethekile likaphethiloli, lapho ukusabela kwe-oxidation kwenzeka ukuze kuqashwe ukugcwala kwe-methanol nokusebenzisa izinsiza.
Xhumana nonjiniyela bethu ukuze uthole isisombululo sokulinganisa sochwepheshe sokuhlushwa kwe-methanol. Cela ikhotheshini yamahhala manje!
