Chinyorwa chino chakaongororwa zvichienderana nemaitiro eScience X ekunyora uye mitemo. Vanyori vakasimbisa zvinhu zvinotevera uku vachiona kuti zvirimo ndezvechokwadi:
Kuchinja kwemamiriro ekunze inyaya yakakomba inoda kutariswa pasi rose. Nyika pasi rose dziri kugadzira marongero ekuderedza migumisiro yekudziya kwepasi rose uye kushanduka kwemamiriro ekunze. Semuenzaniso, European Union inopa gwara rakazara rekuti pave nekusapindirana kwemamiriro ekunze panosvika gore ra2050. Saizvozvowo, European Green Deal inoisa pamberi kuderedza kuburitswa kwemagasi anokonzera kudziya kwepasi.
Kubata kabhoni dhayokisaidhi (CO2) inoburitswa nemakemikari uye kuishandura kuita zvigadzirwa zvinobatsira zvekutengeserana inzira imwe yekuderedza kudziya kwepasi rose uye kuderedza migumisiro yayo. Masayendisiti pari zvino ari kutsvaga tekinoroji yekutora nekushandisa kabhoni (CCU) senzira inovimbisa yekuwedzera kuchengetwa nekugadzirisa kabhoni dhayokisaidhi nemutengo wakaderera.
Zvisinei, tsvakiridzo yepasi rose yeCCU inongogumira pamakemikari anochinja angangoita makumi maviri. Zvichienderana nekusiyana kwezvinoburitswa neCO2, kuwanikwa kwemakemikari akasiyana-siyana kwakakosha, izvo zvinoda tsvakiridzo yakadzama mumaitiro anogona kushandura CO2 kunyangwe paine huwandu hwakaderera.
Chikwata chevaongorori vanobva kuYunivhesiti yeChung-Ang kuKorea chiri kuita tsvakiridzo pamusoro pemaitiro eCCU anoshandisa marara kana zviwanikwa zvakapfuma sezvinhu zvekugadzira kuti zvive nyore kuwana mari.
Chikwata chekutsvagisa chakatungamirwa naPurofesa Sungho Yoon pamwe naPurofesa Chul-Jin Lee munguva pfupi yapfuura chakaburitsa chidzidzo chaikurukura nezvekushandiswa kwecarbon dioxide yemuindasitiri nedolomite, dombo repasi rose uye rinowanzo shandiswa sedimentary rakapfuma mucalcium nemagnesium, kugadzira zvigadzirwa zviviri zvinogona kutengeswa: calcium formate. uye magnesium oxide.
"Kune kufarira kuri kukura mukushandisa kabhoni dhayokisaidhi kugadzira zvigadzirwa zvinokosha zvinogona kubatsira kuderedza migumisiro yekushanduka kwemamiriro ekunze ukuwo zvichiunza mabhenefiti ehupfumi. Nekubatanidza maitiro ehydrogenation ekabhoni dhayokisaidhi uye cation exchange reactions, takagadzira nzira yekuchenesa metal oxides panguva imwe chete uye maitiro ekugadzira mafomati akakosha," akadaro Purofesa Yin.
Mukudzidza kwavo, masayendisiti akashandisa chinhu chinobatsira (Ru/bpyTN-30-CTF) kuwedzera hydrogen mu carbon dioxide, zvichikonzera zvinhu zviviri zvinowedzerwa kukosha: calcium formate ne magnesium oxide. Calcium formate, chinhu chinowedzerwa simende, deicer, uye chikafu chemhuka, chinoshandiswawo mukutsvukisa dehwe.
Kusiyana neizvi, magnesium oxide inoshandiswa zvakanyanya mumaindasitiri ekuvaka nemishonga. Maitiro aya haangogoneki chete, asiwo anokurumidza zvikuru, achigadzira chigadzirwa ichi mumaminitsi mashanu chete patembiricha yemumba. Pamusoro pezvo, vaongorori vanofungidzira kuti maitiro aya anogona kuderedza mukana wekupisa kwepasi rose ne20% zvichienzaniswa nenzira dzechinyakare dzekugadzira calcium formate.
Chikwata ichi chiri kuongororawo kana nzira yavo ichigona kutsiva nzira dziripo dzekugadzira nekudzidza 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," akatsanangura Purofesa Yin.
Kunyange hazvo kushandura kabhoni dhayokisaidhi kuita zvigadzirwa zvinobatsira zvichinzwika sezvakanaka, 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 nharaunda uye muhupfumi. Izvi zvinogona kubatsira kuzadzisa zvinangwa zvekubvisa utsi hwakaipa mune ramangwana," Dr Lee vakapedzisa.

Kana mukasangana nezvikanganiso zvisirizvo, kusarongeka, kana kuti muchida kutumira chikumbiro chekugadzirisa zviri papeji rino, ndapota shandisai fomu iri. Kana muine mibvunzo yakawanda, ndapota shandisai fomu redu rekutaurirana. Kuti muwane mhinduro dzakawanda, shandisai chikamu chemashoko everuzhinji chiri pazasi (teverai gwara).
Maonero enyu akakosha kwatiri. Zvisinei, nekuda kwekuwanda kwemashoko, hatigone kuvimbisa mhinduro yatakapa kune mumwe nemumwe.
