Ethylene glycol (EG), k'hemik'hale ea lejoe la sekhutlo tlhahisong ea polyester, li-antifreeze formulations, le li-resin tsa indasteri, e ntse e bona tsoelo-pele ea phetoho e susumetsoang ke litlhoko tsa botsitso le tsoelo-pele ea theknoloji. Lintlafatso tsa morao-rao mekhoeng ea tlhahiso, lintlafatso tsa taolo, le lits'ebetso tse ncha li fetola karolo ea eona lekaleng la lefats'e la lik'hemik'hale.
1. Green Synthesis Breakthroughs
Katleho e kholo ea theknoloji ea phetolo e ntlafatsang tlhahiso ea ethylene glycol. Bafuputsi ba Asia ba thehile "catalyst" e entsoeng ka koporo e fetolang syngas (motsoako oa hydrogen le carbon monoxide) ka kotloloho ho ethylene glycol e nang le khetho ea 95%, ho feta li-intermediates tsa setso tsa ethylene oxide. Mokhoa ona o fokotsa tšebeliso ea matla ka 30% mme o fokotsa tlhahiso ea CO₂ ka lithane tse 1.2 ka tone ea EG e hlahisoang.
Ts'ebetso, eo hona joale e leng litekong tsa liteko, e tsamaellana le lipheo tsa lefats'e tsa decarbonization mme e ka sitisa mekhoa e tloaelehileng ea tlhahiso e itšetlehileng ka mesaletsa ea lintho tsa khale. Haeba e fokotsehile, e ka 'na ea nolofalletsa limela tsa ethylene glycol hore li kopane ka mokhoa o tsitsitseng le mekhoa ea ho tšoara carbon, ho beha EG e le "k'hemik'hale e tala" e ka bang teng ka har'a liketane tsa phepelo ea selikalikoe.
2. Bio-Based Ethylene Glycol Fumana Traction
Har'a tlhokahalo e ntseng e eketseha ea thepa e tšoarellang, bio-based ethylene glycol e nkiloeng 'mobeng kapa starch ea poone e ntse e hlaha e le mokhoa o mong o sebetsang. Morero oa morao-rao o kopaneng Amerika Boroa o bonts'itse monyetla oa ho belisa litšila tsa temo hore e be monoethylene glycol (MEG) e nang le khabone e tlase ka 40% ho feta tse lekanang le peterole.
Indasteri ea masela, e leng moreki ea ka sehloohong oa EG, e ntse e leka bio-MEG tlhahisong ea fiber ea polyester, ka liphetho tsa pele tse bonts'ang matla a ts'oanang le kamano ea dae. Litšusumetso tsa taolo, joalo ka Leano la EU la Renewable Carbon Initiative, li ntse li potlakisa ho amohela bana, leha liqholotso mabapi le ho ata ha feedstock le ho leka-lekanya litšenyehelo li ntse li tsoela pele.
3. Tlhahlobo ea Taolo ea EG Recycling
Matšoenyeho a ntseng a eketseha ka lebaka la ho phehella ha tikoloho ea ethylene glycol a entse hore ho be le melao e thata. Ka Mphalane 2023, US EPA e ile ea etsa tlhahiso ea litataiso tse ntlafalitsoeng bakeng sa phallo ea metsi a litšila a nang le EG, e laelang lits'ebetso tse tsoetseng pele tsa oxidation ho theola masala a glycol ka tlase ho 50 ppm. Ka nako e ts'oanang, European Union e ntse e etsa tokiso ea moralo oa eona oa Ngoliso, Tlhahlobo, Tumello, le Thibelo ea Lik'hemik'hale (REACH), e hlokang hore bahlahisi ba fane ka lintlha tsa chefo bakeng sa lihlahisoa tsa EG ka 2025.
Mehato ena e ikemiselitse ho sebetsana le likotsi tsa tikoloho, haholo-holo tikolohong ea metsing, moo ho bokellana ha EG ho amanang le ho fokotseha ha oksijene metsing.
4. Likopo tsa Novel Polokelong ea Matla
Ethylene glycol e fumana ts'ebeliso e sa lebelloang lits'ebetsong tsa polokelo ea matla tsa moloko o latelang. Mokhatlo oa liphuputso oa Europe o entse mochine o pholisang oa betri o sa cheng o sebelisa motsoako o fetotsoeng oa EG-metsi, ho matlafatsa taolo ea mocheso ho libeteri tsa lithium-ion ka 25%. Sebopeho, se sebetsang hantle ho -40 ° C ho 150 ° C, se ntse se lekoa ka litšoantšo tsa likoloi tsa motlakase le likarolo tsa polokelo ea marang-rang.
Ho feta moo, lisebelisoa tsa EG-based phase-change-change (PCMs) li ntse li lebisa tlhokomelo bakeng sa polokelo ea matla a mocheso oa letsatsi, 'me liteko tsa morao-rao li fihletse katleho ea 92% ea ho boloka matla ho feta lipotoloho tse 500.
5. Phepelo ea Phepelo ea Phepelo le Liphetoho tsa Libaka
Likhohlano tsa lipolotiki le libotlolo tsa thepa li khothalelitse tlhahiso ea ethylene glycol tikolohong. Mehaho e mecha ea Bochabela bo Hare le Asia Boroa-bochabela e sebelisa likarolo tse nyane tsa tlhahiso e ntlafalitsoeng bakeng sa ho fumaneha ha lijo tsa lehae, ho fokotsa ho itšetleha ka limela tsa mega tse bohareng. Phetoho ena e tlatselletsoa ke litsamaiso tsa taolo ea thepa tse tsamaisoang ke AI tse fokotsang litšila tsa EG makaleng a tlase joalo ka tlhahiso ea libotlolo tsa PET.
Qetello: Thuto ea Lintho Tse Ngata
Lekala la ethylene glycol le eme mateanong a litsela, le leka-lekanya ts'ebeliso ea lona ea indasteri e metseng ka metso le litlhoko tse potlakileng tsa ts'ebetso. Litlhahiso tse entsoeng ka mokhoa o motala, mekhoa e meng e thehiloeng ho baeloji, le lisebelisoa tsa moruo oa selikalikoe li ntse li hlalosa letoto la boleng ba eona, ha melaoana e thata e totobatsa tlhoko ea mekhoa e ikarabellang tikolohong. Ha indasteri ea lik'hemik'hale e ntse e hatela pele ho decarbonization, ho ikamahanya le maemo ha ethylene glycol ho tla supa bohlokoa ba eona 'marakeng o fetohang ka potlako.
