Kugira ngo ubone ibisubizo byiza, turakugira inama yo gukoresha verisiyo nshya ya porogaramu yawe (cyangwa kuzimya uburyo bwo guhuza na interineti muri Internet Explorer).

Ubu, mu kwandika mu kinyamakuru Joule, Ung Lee na bagenzi be batangaje inyigo y’uruganda rw’igerageza rwo gushyira hydrogene karubone mu gukora aside formike (K. Kim et al., Joule https://doi.org/10.1016/j. Joule.2024.01). 003;2024). Ubu bushakashatsi bwerekana uburyo ibintu byinshi by’ingenzi bikorwa mu buryo bwo gukora. Ku rwego rwa reactor, gusuzuma imiterere y’ingenzi ya catalyst nko gukora neza, imiterere, gushonga kw’amazi, ubushyuhe, no kuboneka k’umutungo munini bishobora gufasha kunoza imikorere ya reactor mu gihe ingano y’ibiribwa ikenewe igabanuka. Aha, abanditsi bakoresheje catalyst ya ruthenium (Ru) ishyigikiwe ku buryo buvanze bwa triazine bipyridyl-terephthalonitrile (bwitwa Ru/bpyTNCTF). Banogeje uburyo bwo guhitamo amine zikwiye kugira ngo zifate neza kandi zihindure neza CO2, bahitamo N-methylpyrrolidine (NMPI) nk'amine ikora kugira ngo ifate CO2 kandi iteze imbere uburyo bwo gutera hydrogenation kugira ngo ikore formate, na N-butyl-N-imidazole (NBIM) kugira ngo ibe amine ikora. Nyuma yo gutandukanya amine, formate ishobora gukurwaho kugira ngo irusheho gukora FA binyuze mu gukora trans-adduct. Byongeye kandi, banogeje imikorere ya reactor mu bijyanye n'ubushyuhe, igitutu n'ikigereranyo cya H2/CO2 kugira ngo CO2 ihinduke neza. Mu bijyanye n'imiterere y'imikorere, bakoze igikoresho kigizwe na reactor igenda inyuramo n'inkingi eshatu zikomeza gucukurwa. Bicarbonate isigaye icukurwa mu nkingi ya mbere; NBIM itegurwa ikora trans adduct mu nkingi ya kabiri; umusaruro wa FA uboneka mu nkingi ya gatatu; Guhitamo ibikoresho byo gukoresha icyuma gitera amazi n'umunara nabyo byatekerejweho cyane, ibyuma bitangiza amashanyarazi (SUS316L) byatoranijwe ku bice byinshi, n'ibikoresho bikomoka kuri zirconium (Zr702) byatoranijwe ku munara wa gatatu kugira ngo bigabanye ingese y'icyuma gitera amazi bitewe n'uko kidahura n'ingese yo guteranya lisansi., kandi igiciro ni gito.
Nyuma yo kunoza neza inzira yo gukora—guhitamo ingano y’ibiribwa ikwiye, gushushanya icyuma gitera amazi n’inkingi eshatu zikomeza gusya, guhitamo neza ibikoresho byo mu gice cy’inkingi n’ibipaki by’imbere kugira ngo bigabanye ingese, no kunoza imikorere y’icyuma gitera amazi—abanditsi bagaragaje ko uruganda rw’igerageza rufite ubushobozi bwo guteranya lisansi 10 ku munsi rwubatswe ibiro 10 by’ibinyabiziga bishobora gukomeza gukora neza mu gihe kirenga amasaha 100. Binyuze mu isesengura ryimbitse ry’uko ibintu bishoboka n’ubuzima bw’urusobe rw’ibintu, uruganda rw’igerageza rwagabanyije ikiguzi ku kigero cya 37% n’ubushobozi bwo gushyuha kw’isi ku kigero cya 42% ugereranije n’uburyo busanzwe bwo guteranya lisansi. Byongeye kandi, ubushobozi rusange bw’igikorwa bugera kuri 21%, kandi ingufu zarwo zigereranywa n’iz’imodoka zikoresha lisansi hifashishijwe hydrogen.
