Vatsvaguriri vepaChung-Ang University muSouth Korea vari kudzidza nezvekubata nekushandisa kabhoni vachishandisa marara kana zviwanikwa zvakapfuma sechikafu. Izvi zvinoita kuti tekinoroji iyi ibudirire mune zvemari.
Muchidzidzo chitsva ichi, timu yakatungamirwa naPurofesa Sungho Yoon pamwe naPurofesa Chul-Jin Lee vakaongorora kushandiswa kwecarbon dioxide nedolomite mumaindasitiri kugadzira zvigadzirwa zviviri zvinobudirira mukutengeserana: calcium formate nemagnesium oxide.
Chidzidzo ichi, "Kushandurwa Kwakasimba kweDolomite Magnesium neCalcium Ions kuita Zvigadzirwa Zvinobatsira Zvinowedzera Kukosha Uchishandisa Carbon Dioxide," chakaburitswa muJournal of Chemical Engineering.
Kuchinja kwemamiriro ekunze inyaya yakakomba inofanira kutariswa zvakanyanya. Nekuda kweizvozvo, nyika pasi rose dziri kugadzira mitemo yekuderedza kukanganisa kwayo.
Semuenzaniso, European Union inopa gwara rakazara rekuti pave nekuchengetedzwa kwemamiriro ekunze panosvika gore ra2050. Chibvumirano cheEuropean Green Deal chinosimbisawo kukosha kwekuderedza kuburitswa kwemagasi anodziya pasi.
Nekuda kweizvozvo, masayendisiti ari kutsvaga tekinoroji yekubata nekushandisa kabhoni senzira inovimbisa yekuwedzera kuchengetwa nekugadzirisa kabhoni dhayokisaidhi nemutengo wakaderera.
Zvisinei, tsvakiridzo yepasi rose pamusoro pekutora nekushandisa kabhoni yakaganhurirwa kune macompounds makumi maviri ekushandura.
Zvichienderana nekusiyana kwezvinoburitsa CO2, kuva nemakemikari akasiyana-siyana kwakakosha.
Izvi zvinoratidza kukosha kwekudzidza kwakadzama maitiro ekushandura kabhoni dhayokisaidhi ine huwandu hwakaderera.
Muchidzidzo chitsva ichi, chikwata chakashandisa chinhu chinobatsira kuwedzera hydrogen mucarbon dioxide. Zvakabuda muongororo iyi zvaive zvinhu zviviri zvinobatsira: calcium formate nemagnesium oxide.
Calcium formate inoshandiswa sekuwedzera simende, deicer, uye chikafu chemhuka, pamwe chete nezvimwe zvinoshandiswa zvakaita sekutsvaira dehwe.
Maitiro echikwata haangogoneki chete, asiwo anokurumidza zvikuru, achigadzira chigadzirwa ichi mumaminitsi mashanu chete patembiricha yemumba.
Pakati pezvimwe zvinhu, vaongorori vanofungidzira kuti maitiro aya anogona kuderedza mukana wekupisa kwepasi rose ne20% zvichienzaniswa nenzira dzechinyakare dzekugadzira calcium formate.
"Kune kufarira kuri kukura kwekushandisa kabhoni dhayokisaidhi kugadzira zvigadzirwa zvinokosha zvinogona kubatsira kuderedza migumisiro yekushanduka kwemamiriro ekunze ukuwo zvichiunza mabhenefiti ehupfumi."
Purofesa Yoon akati: "Nekubatanidza maitiro ehydrogenation ecarbon dioxide uye maitiro ekuchinjana kwecation, maitiro akagadzirwa ekuchenesa ma oxide esimbi panguva imwe chete uye kugadzira maforme anokosha."
Vaongorori vakaongorora kana nzira yavo yaigona kutsiva nzira dziripo dzekugadzira. Kuti vaite izvi, vakadzidza kukanganisa kwezvakatipoteredza uye kushanda kwenzira dzekushandura CO2 dzinogara kwenguva refu 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 mikana yekushandura kabhoni dhayokisaidhi kuita zvigadzirwa ichivimbisa, maitiro aya haasi nyore nguva dzose kuwedzera.
Matekinoroji mazhinji eCCU haasati atengeswa nekuti kugona kwawo hupfumi kwakaderera kana tichienzanisa nemaitiro ekare ekutengeserana.
"Tinofanira kusanganisa maitiro eCCU nekudzokorodza marara kuti ashande zvakanaka munharaunda uye muhupfumi. Izvi zvinogona kubatsira kuzadzisa zvinangwa zvekubvisa utsi husina kuburitswa mune ramangwana," Dr Lee vakapedzisa.
Innovation News Network inokuunzirai nhau dzichangoburwa dzekutsvaga nekugadzira zvinhu zvitsva mune zvesainzi, zvakatipoteredza, simba, zvinhu zvakakosha, tekinoroji uye mota dzemagetsi.
Chiziviso: Iyi webhusaiti inzvimbo yakazvimirira uye haina mhosva yezviri mumawebhusaiti ekunze. Ndokumbirawo mucherechedze kuti mafoni anogona kurekodhwa kuitira kudzidziswa nekutarisa. © Pan Europe Networks Ltd.
