South Korea-a Chung-Ang University-a zirchiangtute chuan bawlhhlawh emaw, thilsiam hausa tak takte chu feedstock atan hmangin carbon capture leh utilization process an zirchiang mek a ni. Hei hian technology sum leh pai lama hmasawnna a tichiang a ni.
He zirchianna tharah hian Professor Sungho Yoon leh Associate Professor Chul-Jin Lee te kaihhruai team chuan industrial carbon dioxide leh dolomite hmanga sumdawnna atana hman theih thil pahnih: calcium formate leh magnesium oxide siam chhuah dan an zirchiang a ni.
He zirchianna, “Dynamic Conversion of Dolomite Magnesium and Calcium Ions into Useful Value-Added Products Using Carbon Dioxide” tih chu Journal of Chemical Engineering-ah tihchhuah a ni.
Climate change hi thil pawi tak a ni a, ngaih pawimawh hmasak a ngai a ni. Chuvang chuan khawvel ram hrang hrangah a nghawng tihziaawmna tur policy an siam mek a ni.
Entirnan, European Union chuan kum 2050-a climate neutrality neih theihna turin kaihhruaina kimchang tak a rawt a, European Green Deal hian greenhouse gas emission tihtlem a pawimawhzia a sawi bawk.
Chuvang chuan scientist-te chuan carbon capture leh utilization technology chu carbon dioxide dahkhawmna leh processing man tlawm zawka tihpun theihna kawng beisei awm tak a nih thu an zirchiang mek a ni.
Mahse, khawvel pum huapa carbon man leh hman dan zirchianna chu conversion compound 20 vel chauh a ni.
CO2 emission source hrang hrang ngaihtuah chuan compound hrang hrang neih hi a pawimawh hle.
Hei hian low-concentration carbon dioxide inthlak danglamna kalphung ngun taka zirchian a pawimawhzia a tilang a ni.
He zirchianna tharah hian team hian catalyst (Ru/bpyTN-30-CTF) hmangin carbon dioxide-ah hydrogen an dah a ni. Chumi rah chhuah chu value-added product pahnih a ni a, chungte chu calcium formate leh magnesium oxide te an ni.
Calcium formate hi cement additive, deicer, leh ran chaw additive atan hman a ni a, savun tanning ang chi hmanna dang atan pawh hman a ni bawk.
Team-te kalphung hi a tih theih mai bakah, rintlak takin a rang hle a, room temperature-ah minute nga chhung chauhin product hi an siam chhuak thei a ni.
Thil dang dang bakah, zirchiangtute chuan he kalphung hian khawvel lumna thlen theihna chu 20%-in a tihhniam thei niin an chhut a, chu chu calcium formate siam chhuah dan hlui nen khaikhin chuan a ni.
“Carbon dioxide hmanga thil hlu tak tak siam chhuah duhna a sang chho zel a, hei hian boruak inthlak danglamnain a nghawng tihziaawmna tur a pui thei a, chutih rualin sum leh pai lamah pawh hlawkna a thlen thei bawk.
Professor Yoon-a chuan: “Carbon dioxide hydrogenation reaction leh cation exchange reaction te inzawmkhawmin, a ruala metal oxide tihthianghlim theihna tur leh format hlu tak siam chhuah theihna tur process siam a ni,” a ti.
Hrilhfiahtute chuan an hman dan hian tuna thil siam chhuah dan a thlak thei em tih an zirchiang a ni. Chutiang ti tur chuan sustainable CO2 conversion method hmanga environment impact leh economic viability te an zirchiang a.
“Results a\ang hian kan method hi carbon dioxide conversion ai chuan environment friendly alternative a ni tih kan sawi thei a, chu chuan traditional methods a thlak thei a, industrial carbon dioxide emission tihtlem nan a pui thei bawk,” tiin Professor Yin chuan a sawifiah.
Carbon dioxide chu sustainable taka product-a chantir theihna tur beisei awm tak a nih laiin, heng process te hi scale-a siam a awlsam ngai lo.
CCU technology tam zawk hi sumdawnna kalpui dan pangngai nena khaikhin chuan an economic feasibility a hniam avangin sumdawnna atana hman a la ni lo.
“CCU process hi bawlhhlawh recycling nen kan inzawmkhawm a ngai a, chu chuan environment leh economic lamah pawh a hlawk thei ang. Hei hian nakin lawkah net-zero emissions target tihhlawhtlinna kawngah a pui thei a ni,” tiin Dr Lee chuan a sawi chhunzawm.
