1.U-Eastman Uqalise i-Ethyl Acetate "Isisombululo Esijikelezayo," Ejolise kwi-30% yeMveliso Evela kwi-Renewable Carbon ngo-2027
Ngomhla wama-20 kweyeNkanga ngo-2025, i-Eastman Chemical yabhengeza utshintsho olukhulu lweqhinga: ukuhlanganisa ishishini layo le-ethyl acetate kwihlabathi liphela kwicandelo layo le-"Circular Solutions", igxile ekukhuthazeni imodeli yemveliso evaliweyo kusetyenziswa i-ethanol esekwe kwi-bio njengezinto eziluhlaza. Le nkampani iseke ngaxeshanye amaziko okubuyisela kunye nokuvuselela i-solvent eMntla Melika naseYurophu, ijonge ukufumana ngaphezulu kwama-30% eemveliso zayo ze-ethyl acetate kwimithombo yekhabhoni evuselelekayo ngo-2027. Olu tshintsho lunciphisa ukukhutshwa kwekhabhoni kwimveliso ye-solvent ngama-42% ngelixa igcina imilinganiselo yokusebenza ilingana neemveliso zemveli.
Olu phuhliso luhambelana neentshukumo ezibanzi zoshishino, njengoko kubonwa kwimizamo efana neprojekthi yokuhlaziya i-solvent ecocekileyo eyaqaliswa ngokubambisana yi-PPG kunye ne-SAIC General Motors, emiselwe ukunciphisa ukukhutshwa kwe-CO₂ ngeetoni ezingama-430 ngonyaka. Ezo mizamo zigxininisa umkhwa wokutshintsha kwicandelo leekhemikhali, apho uzinzo luqhutywa ngakumbi ziinjini ezimbini ze-bio-based feedstocks kunye neenkqubo ezijikelezayo eziphambili. Ngokubeka phambili izixhobo ezivuselelekayo kunye nokuhlaziya ngokufanelekileyo, ezi zinto zintsha azinciphisi nje kuphela impembelelo yokusingqongileyo kodwa zikwaphucula ukusebenza kakuhle kwezixhobo, zibeka umlinganiselo omtsha wokuvelisa okuluhlaza kushishino. Ukudibana kwezinto ezifakwa kwi-bio kunye neendlela ezijikelezayo kubonisa indlela epheleleyo yokususa iicarbonization kwiinkqubo zemveliso, kuvula indlela yekamva lemizi-mveliso elizinzileyo nelizinzileyo.
2.I-PPG kunye ne-SAIC-GM ziqalise ngokusesikweni iProjekthi yokuRisayikilisha iSolvent eSuzhou nge-1 ka-Okthobha 2025
Ngomhla woku-1 kweyeDwarha ngo-2025, inkokheli ye-PPG yeengubo zeemoto, ngokubambisana ne-SAIC General Motors, baqalise ngokusesikweni iphulo eliphambili lokuphinda kusetyenziswe izinyibilikisi eSuzhou. Le projekthi iseka inkqubo ebanzi, evaliweyo equka umjikelo opheleleyo wezinto ezinyibilikisileyo: ukusuka kwimveliso kunye nokusetyenziswa ukuya ekubuyiselweni okujoliswe kuko, ukuhlaziywa kwezixhobo, kunye nokusetyenziswa kwakhona. Isebenzisa itekhnoloji yokucoca ephucukileyo, le nkqubo ikhupha ngokufanelekileyo izinto ezicocekileyo kakhulu kwizinto ezinyibilikisileyo.
Le nkqubo yenzelwe ukubuyisa ngaphezulu kweetoni ezingama-430 zezinyibilikisi zenkunkuma minyaka le, ifikelele kwizinga lokusetyenziswa kwakhona elimangalisayo lama-80%. Le mizamo kulindeleke ukuba inciphise ukukhutshwa kwekhabhoni dayoksayidi malunga neetoni ezingama-430 minyaka le, inciphise kakhulu umngcipheko wokusingqongileyo wemisebenzi yokugquma iimoto. Ngokuguqula inkunkuma ibe zizixhobo ezixabisekileyo, intsebenziswano ibeka umlinganiselo omtsha oluhlaza kushishino, ibonisa imodeli enokulinganiswa yoqoqosho olujikelezayo kunye nemveliso ezinzileyo.
3Izazinzulu zaseTshayina ziphumelele kwizinga leekhilotoni zoShishino lwe-Green Ionic Liquid Solvents nge-99% yezinga lokubuyisela
Ngomhla we-18 kweyeSilimela ngo-2025, iprojekthi yokuqala yehlabathi ye-ionic liquid-based regenerated cellulose fiber yaqala ukusebenza eXinxiang, eHenan. Yaphuhliswa liqela lophando elikhokelwa yi-Academician uZhang Suojiang, obu buchwepheshe butsha buthatha indawo ye-asidi ebolayo kakhulu, i-alkalis, kunye ne-carbon disulfide esetyenziswa kwiinkqubo zemveli ze-viscose ngolwelo lwe-ionic olungaguquguqukiyo noluzinzileyo. Inkqubo entsha ifikelela ekukhutshweni kwamanzi amdaka, igesi emdaka, kunye nenkunkuma eqinileyo, ngelixa inezinga lokubuyiswa kwe-solvent elidlula i-99%. Itoni nganye yemveliso inciphisa ukukhutshwa kwe-carbon dioxide malunga neetoni ezingama-5,000.
Sele isetyenziswa kumacandelo afana nokhathalelo lwempilo kunye namalaphu, le mpumelelo ibonelela ngendlela ezinzileyo yotshintsho oluluhlaza kwishishini leefayibha zamakhemikhali, ibeka umlinganiselo wokusetyenziswa kwesinyibilikisi esinobuhlobo nokusingqongileyo kwinqanaba lemizi-mveliso.
