Lembani fomu ili m'munsiyi
Carbon Dioxide (CO2) ndiye kuti malonda owotcha mafuta ndi mpweya wobiriwira kwambiri, womwe umatha kusinthidwa kukhala mafuta othandiza m'njira yokhazikika. Njira imodzi yolongosola za mpweya wa Co2 kukhala mafuta a mafuta ndi njira yotchedwa kuchepetsa ma electrochemical. Koma kukhala wopindulitsa, njirayi imafunikira kusintha kuti isankhe kapena kupanga zinthu zolemera kwambiri. Tsopano, monga mwawuzidwa mu magazini yaurgy Energy, Lawrence Berkeley National Labotale (Labkeley Lab) wapanga njira yatsopano yosinthira chothandizira chamkuwa chomwe chimagwiritsidwa ntchito posankha njirayi.
"Ngakhale tikudziwa kuti mkuwa ndiye chothandizira chabwino kwambiri pazinthu izi, sizikupereka kusadetsa kwa mankhwala kwa mankhwalawa, Spell adatero. "Gulu lathu linazindikira kuti mutha kugwiritsa ntchito malo othandiza a komweko kuti muchite zinthu zosiyanasiyana zosonyeza kusankha kosiyanasiyana."
M'maphunziro am'mbuyomu, ofufuza akhazikitsa bwino kwambiri kuti apatse malo abwino opangira magetsi ndi mankhwala kuti apange zinthu zolemera zolemera za kaboni. Koma mikhalidwe imeneyi imasiyana ndi momwe zinthu zachilengedwe zimachitikira mu ma cell omwe amagwiritsa ntchito zida zopangidwa ndi madzi.
Kuti mudziwe kapangidwe kake ka madzi amtundu wamafuta, monga gawo la Eldel Helturce Plajection of Authorming Stoneer, belu ndi gulu lake lidasandulika mamolekyulu owonda, omwe amadutsa. Kupatula ma ayoni ena. Chifukwa cha katundu wawo wosankha mankhwala, ali oyenera makamaka chifukwa chokhudza kwambiri microenmero.
Chanson Kim, wofufuza m'malo mwa gulu la Bell ndi wolemba woyamba wa pepalali, akufuna kuti achotsere ma catalyst awiri amkuwa ndi ma itomers awiri wamba, a Naphion ndi Stuory. Gulu lomwe likuchita izi kuyenera kusintha chilengedwe pafupi ndi chothandizira-kuphatikizapo PH ndi kuchuluka kwa madzi ndi kaboni dayoboride - m'njira inayake kuti isinthidwe mu mankhwala othandiza. Malonda ndi mafuta amadzimadzi.
Ofufuzawo amagwiritsa ntchito woonda wosanjikiza aliyense wa inomer iliyonse ndi kaphikidwe kawiri kabokosi kothandizidwa ndi zinthu zamkuwa kuti apange filimu, yomwe amatha kuyika pafupi ndi selo ya electrochemi yopangidwa ndi manja. Mukayika jakisoni kaboni dayokiriri mu batire ndikugwiritsa ntchito magetsi, adayeza zomwe zikuyenda bwino pa batire. Kenako anayeza mafuta ndi madzi omwe amasonkhanitsidwa munthawi yoyandikana nayo panthawi yomwe mwachita. Kwa milandu iwiri, adapeza kuti zinthu zolemera za kaboni ndi 80% za mphamvu zomwe zimagwiritsidwa ntchito ndi zomwe zimachitika kuposa 60% pamalo osavomerezeka.
Bungwe la Nsamphatiyi limapereka zabwino kwambiri padziko lonse lapansi: Kusankha kwazinthu zambiri komanso ntchito yayikulu, "belu linatero. Malo osanjikiza awiriwo siabwino kwa zinthu zolemera za kaboni, komanso zimatulutsa zamakono nthawi yomweyo, zomwe zikuwonetsa kuwonjezeka.
Ofufuzawo adazindikira kuti zomwe zidasintha zidali zotsatila za kuchuluka kwa kuchuluka kwa ophatikizidwa mwachindunji pamwamba pa mkuwa. Kuphatikiza apo, mamolekyulu osokoneza bongo omwe amadziunjikira m'derali pakati pa ma inomers awiriwo amatulutsa acidity yakomweko. Kuphatikiza uku kumapangitsa kuti malonda azosathane ndi mavuto omwe amakonda kupezeka pakalibe mafilimu a ionomer.
Pofuna kupititsa patsogolo luso la zomwe anachita, ofufuzawo adatembenukira ku ukadaulo womwe udatsimikiziridwa kuti ndi kanema wa ionomer monga njira ina yowonjezera CO2 ndi P PRIVAGAS. Pogwiritsa ntchito matupi a inomer osefukira kwambiri, ofufuzawo adapeza kuchuluka kwa 250% m'malo olemera olemera kaboni poyerekeza ndi mkuwa wosaneneka komanso magetsi ochuluka.
Ngakhale ofufuza ena amayang'ana ntchito yawo yopanga amphatso atsopano, kupezeka kwa chothandizira sikugwirizana ndi zovuta. Kuwongolera chilengedwe pa chothandizira ndi njira yatsopano komanso yosiyana.
"Sitinabwere ndi chothandizira chatsopano, koma tinagwiritsa ntchito kamvedwe kathu ka kinetics ndikugwiritsa ntchito chidziwitsochi kuti lizititsogolera pabwino," anatero Am'kulu, wopanga wamkulu. Asayansi pamunda wamatekinoloji yamphamvu ku Berkeley labotaries ndi wolemba mapepala.
Gawo lotsatira ndikukulitsa kupanga kwa catalysts. Kuyesa kwa gulu loyambirira la Berkeley lab kunaphatikizapo makina ang'onoang'ono osasunthika, omwe anali osavuta kwambiri kuposa malo akuluakulu owopsa omwe amafunikira pakugwiritsa ntchito malonda. "Sikovuta kutsatira zofunda. Koma njira zamalonda zimatha kuphatikizira mipira yaying'ono yamkuwa," belu linatero belu. Kuonjezera gawo lachiwiri lophimba limakhala lovuta. Kuthekera kwina ndikusakaniza ndikuyika zifumbi ziwirizo pamodzi, ndikuyembekeza kuti amalekanitsa nthawi yomwe imasungunulira. Nanga bwanji ngati satero? Bel adamaliza: "Tingofunika kukhala anzeru." Fotokozerani Kim C, bui jc, luo x ndi ena. Kuthandizira kwamitundu yosinthika kwa electro-kuchepetsa kwa CO2 ku mitundu yambiri ya kaboni kwambiri pogwiritsa ntchito inomer yophimba pa mkuwa.

Nkhaniyi imapangidwanso kuchokera ku izi. Chidziwitso: Zinthuzi zitha kusinthidwa kutalika ndi zomwe zili. Kuti mumve zambiri, chonde lemberani gwero lodziwika.
