Kei te rangahau ngā kairangahau o Te Whare Wānanga o Chung-Ang i Kōrea ki te Tonga i ngā tukanga hopu me te whakamahi waro mā te whakamahi i ngā para, i ngā rauemi taiao whai rawa rānei hei rauemi whāngai. Mā tēnei ka mau tonu te whai huatanga ōhanga o te hangarau.
I roto i te rangahau hou, i tūhuratia e tētahi tīma i arahina e Ahorangi Sungho Yoon me Ahorangi Tuarua Chul-Jin Lee te whakamahinga o te hauhā waro ahumahi me te dolomite hei whakaputa i ngā hua e rua e whai hua ana ki te hokohoko: te konupūmā formate me te konupora waikura.
I whakaputaina te rangahau, "Te Huringa Hihiri o te Magnesium Dolomite me ngā Ion Konupūmā ki ngā Hua Tāpiri Uara Whai Hua mā te Whakamahi i te Hauhā Waro," i roto i te Journal of Chemical Engineering.
He take nui te huringa āhuarangi e tika ana kia aro nui atu ki tēnei. Nō reira, kei te whakawhanake ngā whenua o te ao i ngā kaupapa here hei whakaiti i tōna pānga.
Hei tauira, e whakaaro ana te Kotahitanga o Ūropi i tētahi huinga aratohu whānui hei whakatutuki i te kore pānga o te āhuarangi ki te tau 2050. E whakanui ana hoki te Whakaaetanga Kakariki Pākehā i te hiranga o te whakaiti i ngā tukunga hau kati kōtuhi.
Nā reira, kei te tūhuratia e ngā kaipūtaiao te hangarau hopu me te whakamahi waro hei huarahi whai hua ki te whakawhānui ake i te rokiroki me te tukatuka waro hauhā i te utu iti.
Heoi, ko ngā rangahau ā-ao mō te hopu me te whakamahinga o te waro e whakawhāitihia ana ki te tata ki te 20 ngā matū hurihanga.
I te mea he kanorau ngā pūtake tukunga CO2, he mea nui kia whānuitia te whānuitanga o ngā matū.
E whakaatu ana tēnei i te hiranga o tētahi rangahau hōhonu mō ngā tukanga hurihanga o te hauhā waro iti-kukū.
I roto i te rangahau hou, i whakamahia e te tīma he whakakorikori (Ru/bpyTN-30-CTF) hei tāpiri i te hauwai ki te hauhā waro. Ko te hua i puta ko ngā hua e rua kua tāpirihia te uara: te konupūmā formate me te konupūmā waikura.
E whakamahia ana te konupūmā formate hei tāpiri sima, hei whakakoi i te hinu, hei tāpiri kai kararehe, me ētahi atu whakamahinga anō hoki pērā i te whakakoi kiri.
Ehara i te mea ka taea anake te mahi a te tīma, engari he tino tere hoki, ka taea te whakaputa i te hua i roto i te rima meneti noa iho i te pāmahana rūma.
I roto i ētahi atu mea, e whakatau ana ngā kairangahau ka taea e tēnei tukanga te whakaiti i te kaha o te mahana o te ao mā te 20% ki te whakaritea ki ngā tikanga tuku iho o te whakaputa konupūmā formate.
"Kei te piki haere te hiahia ki te whakamahi i te hauhā waro hei whakaputa hua whai hua hei āwhina i te whakaiti i ngā pānga o te huringa āhuarangi, me te whakaputa hua ōhanga anō hoki."
I mea atu a Ahorangi Yoon: "Mā te whakakotahi i ngā tauhohenga hauwai waro me ngā tauhohenga whakawhiti kationi, kua whakawhanakehia he tukanga hei pure i ngā waikura whakarewa me te whakaputa i te formate whai hua i te wā kotahi."
I arotakehia e ngā kairangahau mēnā ka taea e tā rātou tikanga te whakakapi i ngā tikanga whakaputa o nāianei. Hei mahi i tēnei, i akohia e rātou te pānga ki te taiao me te oranga ōhanga o ngā tikanga hurihanga CO2 pumau.
"I runga i ngā hua, ka taea e mātou te kī he huarahi pai ki te taiao tā mātou tikanga hei whakakapi i te hurihanga o te hauhā waro, ka taea te whakakapi i ngā tikanga tuku iho, me te āwhina ki te whakaiti i ngā tukunga hauhā ahumahi," te whakamārama a Ahorangi Yin.
Ahakoa he pai ngā tūmanakohanga mō te huri i te hauhā waro hei hua mō te oranga tonutanga, ehara i te mea ngāwari te whakanui ake i ēnei tukanga.
Kāore anō kia arumonitia te nuinga o ngā hangarau CCU nā te mea he iti ake te whaihua ohaoha ki te whakataurite ki ngā tukanga arumoni tuku iho.
"Me whakakotahi tātou i te tukanga CCU me te hangarua para kia whai hua ai mō te taiao me te ōhanga. Tērā pea ka āwhina tēnei ki te whakatutuki i ngā whāinga kore tukunga ā muri ake nei," te whakatau a Tākuta Lee.
Mā te Innovation News Network koe e kawe mai ngā pūrongo hou mō ngā rangahau me ngā mahi auaha i roto i te pūtaiao, te taiao, te pūngao, ngā rauemi mata nui, te hangarau me ngā waka hiko.
Whakakape: He tomokanga motuhake tēnei paetukutuku, ā, kāore e whai kawenga mō ngā ihirangi o ngā paetukutuku o waho. Kia mōhio mai, ka taea te hopu i ngā waeatanga waea mō ngā kaupapa whakangungu me te aroturuki. © Pan Europe Networks Ltd.
