Sweswi, loko va tsala eka journal ya Joule, Ung Lee na vatirhikulobye va vika ndzavisiso wa xitirhisiwa xo ringeta xo endla hydrogenating carbon dioxide ku humesa formic acid (K. Kim et al., Joule https://doi.org/10.1016/j. Joule.2024.01 ). 003;2024). Dyondzo leyi yi kombisa ku antswisiwa ka swiphemu swo hlayanyana swa nkoka swa endlelo ra vumaki. Eka xiyimo xa reactor, ku tekeriwa enhlokweni ka swivumbeko swa nkoka swa catalyst swofana na catalytic efficiency, morphology, ku n’oka ematini, ku tiya ka mahiselo, na ku kumeka ka switirhisiwa swa xikalo lexikulu swinga pfuneta ku antswisa matirhelo ya reactor loko kurikarhi ku hlayisiwa nhlayo ya feedstock leyi lavekaka ehansi. Laha, vatsari va tirhise xihlohloteri xa ruthenium (Ru) lexi seketeriweke eka xivumbeko xa mixed covalent triazine bipyridyl-terephthalonitrile (lexi vuriwaka Ru/bpyTNCTF). Va antswisile ku hlawuriwa ka ti amine pairs leti faneleke eka ku khoma na ku hundzuriwa ka CO2 hi ndlela leyinene, va hlawula N-methylpyrrolidine (NMPI) tani hi reactive amine ku khoma CO2 na ku tlakusa hydrogenation reaction ku vumba formate, na N-butyl-N-imidazole (NBIM) ku tirha tani hi reactive amine. Loko yi hambanisiwile amine, formate yinga hambanisiwa kuva yi yisa emahlweni vuhumelerisi bya FA hiku endliwa ka trans-adduct. Ku engetela kwalano, va antswisile swiyimo swa matirhelo ya reactor kuya hi mahiselo, ntshikelelo na H2/CO2 ratio kuva ku kurisiwa ku cinca ka CO2. Hi mayelana na dizayini ya maendlelo, va endle xitirhisiwa lexi vumbiwaka hi trickling bed reactor na tikholomu tinharhu leti yaka emahlweni ta distillation. Bicarbonate leyi saleke yi distilled off eka kholomo yosungula; NBIM yi lulamisiwa hiku vumba trans adduct eka kholomo ya vumbirhi; xiendliwa xa FA xi kumiwa eka kholomo ya vunharhu; Ku hlawuriwa ka switirhisiwa swa reactor na xihondzo switlhele swi tekeriwa enhlokweni hi vukheta, laha stainless steel (SUS316L) yi hlawuriweke eka swiphemu swotala, na xitirhisiwa xa mabindzu lexi sekeriweke eka zirconium (Zr702) lexi hlawuriweke eka xihondzo xa vunharhu ku hunguta ku bola ka reactor hikokwalaho ka ku tiya ka yona eka ku bola ka nhlengeletano ya mafurha. , naswona mali ya kona yi le hansi swinene.
Endzhaku ko antswisa hi vukheta endlelo ra vuhumelerisi—ku hlawula xitirhisiwa lexinene xa swakudya, ku dizayina trickling bed reactor na tikholomu tinharhu leti yaka emahlweni ta distillation, ku hlawula hi vukheta switirhisiwa swa miri wa kholomo na ku paka endzeni ku hunguta ku bola, na ku lulamisa kahle swiyimo swa matirhelo ya reactor—vatsari va kombisa leswaku ku akiwile xitirhisiwa xo ringeta lexi nga na vuswikoti bya siku na siku bya 10 lexi kotaka ku hlayisa ku tiya ku tirhisiwa ku tlula tiawara ta 100. Hi ku tirhisa nxopaxopo wa vukheta wa ku koteka na xirhendzevutani xa vutomi, feme yo ringeta yi hungute ku durha hi 37% na vuswikoti byo hisa misava hi 42% loko ku pimanisiwa na maendlelo ya ndhavuko ya vuhumelerisi bya nhlengeletano ya mafurha. Ku engetela kwalaho, ku tirha kahle hinkwako ka endlelo ku fika eka 21%, naswona ku tirha kahle ka rona ka eneji ku ringanisiwa na ka mimovha ya tisele ta mafurha leyi fambiwaka hi hayidirojeni.
