Vatsvaguriri vepaChung-Ang University muSouth Korea vakauya nepfungwa yekushandisa industrial carbon dioxide nedolomite, dombo re sedimentary rakajairika uye rakapararira rakapfuma mu calcium ne magnesium, kugadzira zvigadzirwa zviviri zvinotengeswa: calcium formate ne magnesium oxide.
Mune chinyorwa chakaburitswa muJournal of Chemical Engineering, masayendisiti anotsanangura kuti tekinoroji yavo yekutora nekushandisa kabhoni (CCU) yakavakirwa pamaitiro anobatanidza maitiro ehydrogenation yekabhoni dioxide uye maitiro ekuchinjana kwecation kuti panguva imwe chete achenese ma oxide esimbi uye agadzire kugadzirwa kweformate yakakosha uye yakakosha.
Zvikuru, vakashandisa chinhu chinobatsira (Ru/bpyTN-30-CTF) kuwedzera hydrogen mu carbon dioxide, zvichigadzira zvinhu zviviri zvinobatsira. Kuchenesa dehwe kunoshandisawo calcium formate, zvinowedzerwa nesimende, deicers uye zvinowedzerwa zvekudya zvemhuka. Kune rumwe rutivi, Magnesium oxide inoshandiswa zvakanyanya mumaindasitiri ekuvaka nekugadzira mishonga.
Vaongorori vakuru Seongho Yoo naChul-Jin Lee vanoti maitiro aya haangogoneki chete, asiwo anokurumidza zvikuru, achigadzira chigadzirwa ichi mumaminitsi mashanu chete patembiricha yemumba. Pamusoro pezvo, timu yake inofungidzira kuti maitiro aya anogona kuderedza mukana wekupisa kwepasi rose ne20% zvichienzaniswa nenzira dzechinyakare dzekugadzira calcium formate.
Chikwata chakaongororawo kana nzira yavo yaigona kutsiva nzira dzekugadzira dziripo nekuongorora kukanganisa kwayo nharaunda uye kushanda kwayo muhupfumi.
"Zvichibva pamhedzisiro, tinogona kutaura kuti nzira yedu inzira isingakuvadzi nharaunda panzvimbo pekushandura kabhoni dioxide iyo inogona kutsiva nzira dzechinyakare uye kubatsira kuderedza kuburitswa kwekabhoni dioxide mumaindasitiri," akadaro Yun.
Nyanzvi iyi yakataura kuti kunyange hazvo kushandura kabhoni dhayokisaidhi kuita zvigadzirwa zvinobatsira zvichinzwika zvakanaka, maitiro aya haasi nyore nguva dzose kuwedzera. Mazhinji matekinoroji eCCU haasati atengeswa nekuti kugona kwawo hupfumi kwakaderera kana tichienzanisa nemaitiro makuru ekutengeserana.
"Tinofanira kusanganisa maitiro eCCU nekudzokorodza marara kuti ashande zvakanaka munharaunda uye muhupfumi. Izvi zvinogona kubatsira kuzadzisa zvinangwa zvekubvisa utsi husina kuburitswa mune ramangwana," akadaro Lee.
