Iyi nkuru yasuzumwe hakurikijwe amabwiriza n'amabwiriza ya Science X yo kwandika. Abanditsi bashimangiye ibintu bikurikira mu gihe bagenzura ko ibikubiye muri iyi nkuru ari ukuri:
Imihindagurikire y'ikirere ni ikibazo gikomeye gisaba ko isi yose ishyira imbere. Ibihugu hirya no hino ku isi birimo gutegura politiki zo kugabanya ingaruka z'ubushyuhe bw'isi n'imihindagurikire y'ikirere. Urugero, Umuryango w'Ubumwe bw'u Burayi utanga amabwiriza arambuye yo kugera ku kutagira aho bibogamira mu mihindagurikire y'ikirere bitarenze umwaka wa 2050. Mu buryo nk'ubwo, Amasezerano y'Uburayi arengera ibidukikije ashyira imbere kugabanya imyuka ihumanya ikirere.
Gufata dioxyde de carbone (CO2) iva mu kirere no kuyihinduramo ibikoresho by'ingirakamaro mu bucuruzi ni bumwe mu buryo bwo kugabanya ubushyuhe bw'isi no kugabanya ingaruka zabyo. Abahanga mu bya siyansi ubu barimo gushakisha ikoranabuhanga ryo gufata no gukoresha karubone (CCU) nk'uburyo bwiza bwo kwagura ububiko n'itunganywa rya dioxyde de carbone ku giciro gito.
Ariko, ubushakashatsi ku isi yose bwa CCU bugarukira ahanini ku bintu bihindura umubiri bigera kuri 20. Bitewe n’ubwoko butandukanye bw’ibyuka bihumanya ikirere bya CO2, kuboneka kw’ibintu byinshi ni ingenzi cyane, bizasaba ubushakashatsi bwimbitse ku bikorwa bishobora guhindura CO2 nubwo byaba biri hasi.
Itsinda ry'abashakashatsi bo muri Kaminuza ya Chung-Ang yo muri Koreya ririmo gukora ubushakashatsi ku mikorere ya CCU ikoresha imyanda cyangwa umutungo kamere mwinshi nk'ibikoresho fatizo kugira ngo bibe byashoboka mu bukungu.
Itsinda ry’ubushakashatsi riyobowe na Porofeseri Sungho Yoon na Porofeseri wungirije Chul-Jin Lee baherutse gusohora ubushakashatsi ku ikoreshwa rya dioxyde de carbone na dolomite, ibuye risanzwe kandi risanzwe rikungahaye kuri kalisiyumu na manyeziyumu, kugira ngo hakorwe ibintu bibiri bishobora gucuruzwa: calcium formate. na magnesium oxide.
Porofeseri Yin yagize ati: “Hari ukwiyongera gushishikazwa no gukoresha dioxyde de carbone mu gukora ibintu by’agaciro bishobora gufasha kugabanya ingaruka z’imihindagurikire y’ikirere mu gihe bitanga inyungu mu bukungu. Mu guhuza uburyo bwo gukaraba dioxyde de carbone na cation exchange reactions, twashyizeho uburyo bwo gusukura icyarimwe oxyde de metal na processes kugira ngo hakorwe formates z’agaciro.”
Mu bushakashatsi bwabo, abahanga bakoresheje katalisiti (Ru/bpyTN-30-CTF) kugira ngo bongere hydrogen muri dioxyde de carbone, bituma habaho ibintu bibiri byiyongereyeho agaciro: calcium formate na magnesium oxide. Calcium formate, inyunganizi ya sima, deicer, n'inyongeramusaruro ku biryo by'amatungo, nayo ikoreshwa mu gusiga uruhu.
Mu buryo bunyuranye, okiside ya manyeziyumu ikoreshwa cyane mu nganda z’ubwubatsi n’iz’imiti. Ubu buryo ntibushoboka gusa, ahubwo bunakora vuba cyane, bugatanga umusaruro mu minota 5 gusa ku bushyuhe bw’icyumba. Byongeye kandi, abashakashatsi bavuga ko ubu buryo bushobora kugabanya ubushyuhe bw’isi ku kigero cya 20% ugereranije n’uburyo gakondo bwo gukora formate ya calcium.
Itsinda ririmo kandi gusuzuma niba uburyo bwabo bushobora gusimbura uburyo busanzwe bwo gukora hifashishijwe kwiga ingaruka zabwo ku bidukikije n’ubushobozi bw’ubukungu. Porofeseri Yin yasobanuye ati: “Dushingiye ku bisubizo, 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 guhindura dioxyde de carbone mo ibintu by'ingirakamaro bisa nkaho ari byiza, ibi bikorwa ntibyoroshye buri gihe kubikoresha. Ikoranabuhanga rya CCU rinini ntirirashyirwa mu bucuruzi kuko ubushobozi bwaryo mu bukungu buri hasi ugereranije n'ibikorwa bisanzwe by'ubucuruzi. Dr Lee yasoje agira ati: “Tugomba guhuza uburyo bwa CCU n'uburyo bwo kongera gukoresha imyanda kugira ngo bibe byiza ku bidukikije no mu bukungu. Ibi bishobora gufasha kugera ku ntego zo gusohora imyuka ihumanya ikirere mu gihe kizaza.”

Niba uhuye n'ikosa ry'imyandikire, amakosa, cyangwa wifuza gutanga icyifuzo cyo guhindura ibikubiye kuri uru rupapuro, nyamuneka koresha iyi fomu. Ku bibazo rusange, nyamuneka koresha fomu yacu yo kutwandikira. Kugira ngo ubone ibitekerezo rusange, koresha igice cy'ibitekerezo rusange kiri hepfo (kurikiza amabwiriza).
Igitekerezo cyawe ni ingenzi kuri twe. Ariko, kubera ubwinshi bw'ubutumwa, ntabwo dushobora kwemeza igisubizo cyihariye.
Aderesi imeri yawe ikoreshwa gusa mu kubwira abayoherereje imeri. Aderesi yawe cyangwa aderesi y'uwayohererejwe nta kindi kizakoreshwa. Amakuru wanditse azagaragara muri imeri yawe kandi ntazabikwa na Phys.org mu buryo ubwo aribwo bwose.
Akira amakuru mashya ya buri cyumweru cyangwa ya buri munsi mu gasanduku kawe k'ubutumwa. Ushobora kwiyambura igihe icyo ari cyo cyose kandi ntabwo tuzasangiza amakuru yawe abandi bantu.
Dutuma ibikubiye muri iyi porogaramu bigerwaho na buri wese. Tekereza gushyigikira intego ya Science X ukoresheje konti y'igiciro.
