Abashakashatsi bo muri Kaminuza ya Chung-Ang muri Koreya y'Epfo bagize igitekerezo cyo gukoresha dioxyde de carbone na dolomite, ibuye risanzwe kandi rikunze kuboneka mu butaka rikungahaye kuri kalisiyumu na manyeziyumu, kugira ngo hakorwe ibintu bibiri bishobora kugurishwa: calcium formate na magnesium oxide.
Mu nyandiko yasohotse mu kinyamakuru Journal of Chemical Engineering, abahanga mu bya siyansi basobanura ko ikoranabuhanga ryabo ryo gufata no gukoresha karuboni (CCU) rishingiye ku buryo buhuza uburyo bwo guhinduranya karuboni dioxyde de carbone na cation exchange reactions kugira ngo icyarimwe hasukurwe oxyde de metal kandi hakorwe umusaruro wa formate ufite agaciro kanini kandi ufite agaciro kanini.
By’umwihariko, bakoresheje katalisiti (Ru/bpyTN-30-CTF) kugira ngo bongere hydrogen muri dioxyde de carbone, bigatuma habaho ibintu bibiri by’agaciro. Gutunganya uruhu binakoresha formate ya kalisiyumu, inyongeramusaruro za sima, deicers n’inyongeramusaruro z’ibiryo by’amatungo. Oxyde ya manyeziyumu, ku rundi ruhande, ikoreshwa cyane mu nganda z’ubwubatsi n’iz’imiti.
Abashakashatsi bakuru Seongho Yoo na Chul-Jin Lee bavuga ko iki gikorwa kidashoboka gusa, ahubwo ko ari n'igihe gito cyane, kuko gishobora gukorwa mu minota itanu gusa ku bushyuhe bw'icyumba. Byongeye kandi, itsinda rye riteganya ko iki gikorwa gishobora kugabanya ubushyuhe bw'isi ku kigero cya 20% ugereranije n'uburyo gakondo bwo gukora calcium formate.
Itsinda ryanasuzumye niba uburyo bwabo bushobora gusimbura uburyo busanzwe bwo gukora busuzuma ingaruka zabwo ku bidukikije n'ubushobozi bw'ubukungu.
Yun yagize ati: “Dushingiye ku bisubizo byatanzwe, 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.”
Uyu muhanga mu bya siyansi yavuze ko nubwo guhindura dioxyde de carbone mo ibintu by'ingirakamaro bisa nkaho ari byiza, ariko ibi bikorwa ntabwo byoroshye kubikoresha buri gihe. Ikoranabuhanga rya CCU ritari ryagurishwa kubera ko ubushobozi bwaryo mu bukungu buri hasi ugereranije n'ibikorwa bisanzwe by'ubucuruzi.
Lee yagize ati: “Tugomba guhuza inzira ya CCU n’imyanda yo kongera kuyikoresha kugira ngo igire akamaro mu bidukikije no mu bukungu. Ibi bishobora gufasha kugera ku ntego zo kutazasohora imyuka ihumanya ikirere mu gihe kizaza.”
