Abanoonyereza mu yunivasite ya Chung-Ang mu South Korea bajja n’ekirowoozo ky’okukozesa omukka gwa kaboni dayokisayidi mu makolero ne dolomite, olwazi olumanyiddwa ennyo era olubunye ennyo olulimu ekirungo kya calcium ne magnesium, okukola ebintu bibiri ebisobola okutundibwa: calcium formate ne magnesium oxide.
Mu lupapula olwafulumiziddwa mu Journal of Chemical Engineering, bannassaayansi bannyonnyola nti tekinologiya waabwe ow’okukwata n’okukozesa kaboni (CCU) yeesigamiziddwa ku nkola egatta enkola za kaboni dayokisayidi ezikola haidrojeni n’ensengekera z’okuwanyisiganya cation okusobola okulongoosa okisayidi z’ebyuma mu kiseera kye kimu ne zikola formate ey’omuwendo omungi, ow’omuwendo omungi. okufulumya.
Okusingira ddala, baakozesa ekirungo ekiziyiza (Ru/bpyTN-30-CTF) okugatta haidrojeni mu kaboni dayokisayidi, ne bakola ebintu bibiri eby’omuwendo. Okulongoosa amaliba era kukozesa ekirungo kya calcium formate, ebirungo ebigattibwa mu seminti, eddagala eriggya ice n’ebirungo ebigattibwa mu mmere y’ebisolo. Ate magnesium oxide akozesebwa nnyo mu by’okuzimba n’okukola eddagala.
Abanoonyereza abakulembeddemu Seongho Yoo ne Chul-Jin Lee bagamba nti enkola eno tekoma ku kusoboka, wabula era ya mangu nnyo, okufulumya ekintu kino mu ddakiika ttaano zokka ku bbugumu erya bulijjo. Okugatta ku ekyo, ttiimu ye ebalirira nti enkola eno eyinza okukendeeza ku busobozi bw’ebbugumu ly’ensi ebitundu 20% bw’ogeraageranya n’enkola ez’ekinnansi ez’okufulumya ekirungo kya calcium formate.
Ttiimu eno era yeekenneenyezza oba enkola yaabwe esobola okudda mu kifo ky’enkola z’okufulumya eziriwo nga yeetegereza enkosa yaayo eri obutonde bw’ensi n’obusobozi bw’ebyenfuna.
“Okusinziira ku bivuddemu, tusobola okugamba nti enkola yaffe nkola ya bulabe eri obutonde bw’ensi okusinga okukyusa kaboni dayokisayidi eyinza okudda mu kifo ky’enkola ez’ennono n’okuyamba okukendeeza ku kaboni dayokisayidi afulumizibwa mu makolero,” Yun bwe yagambye.
Munnasayansi ono yagamba nti wadde ng’okukyusa kaboni dayokisayidi okufuuka ebintu eby’omugaso kiwulikika nga kisuubiza, enkola zino si nnyangu bulijjo okuzigerageranya. Tekinologiya wa CCU asinga tannaba kutundibwa kubanga obusobozi bwayo mu by’enfuna butono bw’ogeraageranya n’enkola z’obusuubuzi enkulu.
"Twetaaga okugatta enkola ya CCU n'okuddamu okukola kasasiro okusobola okugifuula ey'omugaso eri obutonde bw'ensi n'ebyenfuna.Kino kiyinza okuyamba okutuukiriza ebiruubirirwa by'okufulumya obucaafu obutaliimu buzito mu biseera eby'omu maaso," Lee bwe yagambye.
