Kuti mupeze zotsatira zabwino, tikukulimbikitsani kugwiritsa ntchito mtundu watsopano wa msakatuli wanu (kapena kuzimitsa mawonekedwe ogwirizana mu Internet Explorer).

Tsopano, polemba mu magazini ya Joule, Ung Lee ndi anzake akunena za kafukufuku wa chomera choyesera chopangira hydrogenating carbon dioxide kuti apange formic acid (K. Kim et al., Joule https://doi.org/10.1016/j. Joule.2024.01). 003;2024). Kafukufukuyu akuwonetsa kukonza bwino zinthu zingapo zofunika kwambiri pakupanga. Pa mulingo wa reactor, kuganizira za zinthu zofunika kwambiri monga catalytic efficiency, morphology, kusungunuka kwa madzi, kukhazikika kwa kutentha, ndi kupezeka kwa zinthu zambiri kungathandize kukonza magwiridwe antchito a reactor pamene akusunga kuchuluka kwa chakudya chofunikira kukhala kochepa. Pano, olembawo adagwiritsa ntchito ruthenium (Ru) catalyst yothandizidwa ndi chimango chosakanikirana cha triazine bipyridyl-terephthalonitrile (chotchedwa Ru/bpyTNCTF). Iwo anakonza bwino kusankha ma amine awiriawiri oyenera kuti agwire bwino ntchito ya CO2, posankha N-methylpyrrolidine (NMPI) ngati amine yogwira ntchito kuti igwire CO2 ndikulimbikitsa hydrogenation reaction kuti ipange formate, ndi N-butyl-N-imidazole (NBIM) kuti ikhale amine yogwira ntchito. Atapatula amine, formate ikhoza kuchotsedwa kuti ipange FA yambiri kudzera mu trans-adduct. Kuphatikiza apo, adasintha momwe ntchito ya reactor imagwirira ntchito malinga ndi kutentha, kuthamanga ndi chiŵerengero cha H2/CO2 kuti awonjezere kusintha kwa CO2. Ponena za kapangidwe ka njira, adapanga chipangizo chokhala ndi creator yoyenda pang'onopang'ono ndi mizati itatu yopitilira yothira. Bicarbonate yotsalira imasungunuka mu mizati yoyamba; NBIM imakonzedwa popanga trans adduct mu mizati yachiwiri; mankhwala a FA amapezeka mu mizati yachitatu; Kusankha zipangizo zogwiritsira ntchito riyakitala ndi nsanja kunaganiziridwanso mosamala, ndipo chitsulo chosapanga dzimbiri (SUS316L) chinasankhidwa pa zinthu zambiri, ndipo chinthu chopangidwa ndi zirconium (Zr702) chinasankhidwa pa nsanja yachitatu kuti chichepetse dzimbiri la riyakitala chifukwa cha kukana kwake ku dzimbiri pakupanga mafuta, ndipo mtengo wake ndi wotsika.
Pambuyo pokonza bwino njira yopangira zinthu—kusankha chakudya choyenera, kupanga reactor yoyenda pang'onopang'ono ndi mizati itatu yopitilira kusungunuka, kusankha mosamala zipangizo za thupi la mizati ndi zomangira zamkati kuti muchepetse dzimbiri, ndikusintha bwino momwe ntchito ya reactor imagwirira ntchito—olembawo akuwonetsa kuti chomera choyendetsa chomwe chili ndi mphamvu ya tsiku ndi tsiku ya makilogalamu 10 chamangidwa chomwe chingathe kusunga ntchito yokhazikika kwa maola opitilira 100. Kudzera mu kusanthula mosamala momwe zinthu zikuyendera komanso momwe zinthu zilili, chomera choyendetsa chinachepetsa ndalama ndi 37% ndipo kuthekera kwa kutentha kwa dziko lapansi ndi 42% poyerekeza ndi njira zachikhalidwe zopangira mafuta. Kuphatikiza apo, kugwira ntchito bwino kwa njirayi kumafika pa 21%, ndipo kugwiritsa ntchito mphamvu zake kumafanana ndi magalimoto amafuta omwe amagwiritsa ntchito hydrogen.
