Abashakashatsi bo muri Kaminuza ya Chung-Ang muri Koreya y'Epfo barimo kwiga uburyo bwo gufata no gukoresha karubone hakoreshejwe imyanda cyangwa umutungo kamere mwinshi nk'ibiribwa. Ibi byemeza ko ikoranabuhanga rishobora kubaho mu bukungu.
Muri ubu bushakashatsi bushya, itsinda riyobowe na Porofeseri Sungho Yoon na Porofeseri wungirije Chul-Jin Lee ryasuzumye ikoreshwa rya dioxyde de carbone na dolomite mu nganda kugira ngo hakorwe ibintu bibiri bishobora kugurishwa: calcium formate na magnesium oxide.
Ubushakashatsi, “Guhindura ioni za manyeziyumu na kalisiyumu bivuye muri dolomite bikavamo ibintu by’ingirakamaro byongerewe agaciro hakoreshejwe dioxyde de carbone,” bwasohotse mu kinyamakuru Journal of Chemical Engineering.
Imihindagurikire y'ikirere ni ikibazo gikomeye kigomba kwitabwaho cyane. Kubera iyo mpamvu, ibihugu hirya no hino ku isi birimo gushyiraho politiki zo kugabanya ingaruka zayo.
Urugero, Umuryango w’Ubumwe bw’u Burayi utanga amabwiriza arambuye yo kugera ku kutagira aho guhurira n’imihindagurikire y’ikirere bitarenze umwaka wa 2050. Amasezerano y’Uburayi arengera ibidukikije anashimangira akamaro ko kugabanya imyuka ihumanya ikirere.
Kubera iyo mpamvu, abahanga mu bya siyansi barimo gushakisha ikoranabuhanga ryo gufata no gukoresha karuboni nk'uburyo bwiza bwo kongera ububiko bwa karuboni no guhindura CO2 ku giciro gito.
Ariko, ubushakashatsi ku isi yose ku gufata no gukoresha karubone bugarukira ku bintu bigera kuri 20 bihindura umwuka.
Bitewe n'ubwoko butandukanye bw'ibyuka bihumanya ikirere bya CO2, kugira ubwoko bwinshi bw'ibintu bihumanya ikirere ni ingenzi cyane.
Ibi bigaragaza akamaro ko kwiga byimbitse inzira zo guhindura umwuka wa karuboni urimo umwuka muke.
Muri ubwo bushakashatsi bushya, itsinda ryakoresheje katalyst (Ru/bpyTN-30-CTF) kugira ngo ryongere hydrogen muri dioxyde de carbone. Ibisubizo byavuyemo ibintu bibiri byiyongereyeho agaciro: calcium formate na magnesium oxide.
Formate ya kalisiyumu ikoreshwa nk'inyongeramusaruro ya sima, ikoreshwa mu gusukura, n'ibiryo by'amatungo, ndetse n'ibindi bikorwa nko gusiga uruhu.
Uburyo itsinda ryakoze ntabwo bushoboka gusa, ahubwo bunakora vuba cyane, bugatanga umusaruro mu minota itanu gusa ku bushyuhe bw'icyumba.
Mu bindi, abashakashatsi bavuga ko iyi gahunda ishobora kugabanya ubushyuhe bw'isi ku kigero cya 20% ugereranije n'uburyo gakondo bwo gukora calcium formate.
“Hari ukwiyongera k’ubushake bwo gukoresha dioxyde de carbone mu gukora ibintu by’agaciro bishobora gufasha kugabanya ingaruka z’imihindagurikire y’ikirere mu gihe bitanga inyungu mu bukungu.”
Porofeseri Yoon yagize ati: “Mu guhuza uburyo bwo gukaraba hydrogenation ya dioxyde de carbone na cation exchange reactions, hakozwe uburyo bwo gusukura oxides z’icyuma icyarimwe no gukora formate y’agaciro.”
Abashakashatsi basuzumye niba uburyo bwabo bushobora gusimbura uburyo bukoreshwa ubu. Kugira ngo babigereho, bigaga ku ngaruka ku bidukikije n'ubushobozi bwo guhindura CO2 mu buryo burambye mu bukungu.
Porofeseri Yin yasobanuye ati: “Dushingiye ku bisubizo twabonye, ​​dushobora kuvuga ko uburyo bwacu ari ubundi buryo butangiza ibidukikije aho guhindura dioxyde de carbone bushobora gusimbura uburyo gakondo kandi bugafasha kugabanya imyuka ihumanya ikirere ihumanya ikirere mu nganda.”
Nubwo amahirwe yo guhindura dioxyde de carbone mo ibikomoka ku bimera mu buryo burambye ari meza, izi nzira ntizoroshye kuzikoresha buri gihe.
Ikoranabuhanga rya CCU rinini ntirirashyirwa mu bucuruzi kuko ubushobozi bwaryo mu bukungu buri hasi ugereranije n'uburyo busanzwe bwo gukora ubucuruzi.
Dr Lee yasoje agira ati: “Tugomba guhuza inzira ya CCU n’iy’imyanda yo kongera kuyikoresha kugira ngo ibe ingirakamaro ku bidukikije no mu bukungu. Ibi bishobora gufasha kugera ku ntego zo kutazasohora imyuka ihumanya ikirere mu gihe kizaza.”
Innovation News Network ibagezaho amakuru agezweho y’ubushakashatsi n’udushya mu bya siyansi, ibidukikije, ingufu, ibikoresho by’ingenzi, ikoranabuhanga n’ibinyabiziga bikoresha amashanyarazi.
