Namhlanje yenye yezona zinto zixhalabisayo esinokuba nazo njengabantu abahlala eMhlabeni zizama sinciphise kangangoko isixa se-CO2 esikhupha emoyeni, into ekuboniswa ukuba iyintlekele kwixesha elizayo ukuba sisinde kwiplanethi nakwezinye izinto eziphilayo. Le nkxalabo inyuke kakhulu, ngakumbi ngenxa yamanyathelo athile athathwe ngoorhulumente abathile abatyeshela naluphi na uhlobo lwesivumelwano okanye isivumelwano esisayinwe lilizwe labo kwiminyaka ngaphambi kwegunya labo.
Ngaphandle kokuzama ukuba kuxhomekeke ekubeni ngubani onokuthi abuyele ezingqondweni okanye hayi kwaye, ngaphezulu kwayo yonke loo nto, uyeke ukukhangela izibonelelo zabo okwethutyana kwaye ujonge kancinci kwilifa abaza kulishiya kwizizukulwana ezizayo, kubonakala ngathi okona kunomdla ngoku kuyadlula ukufumanisa indlela okanye indlela esinokuphelisa ngayo i-CO2 esele iqokelele kumoya weplanethi yethu Kwaye, kuyabonakala, enye yeendlela esisandula ukufumanisa ukufezekisa oku kukusebenzisa isimbiwa esibhaptiziweyo ngegama le magnesite.
Magnisite, izimbiwa ezinako ukufunxa kunye nokugcina ikhabhon diokside
Kwabo bangayazi i-magnesite, bachaza ukuba sijamelene nezimbiwa ekude kakhulu nokuba zintsha kuba ikho kwindalo. Olunye lweempawu ezenza le minerali yenye yezona zinomdla wokulwa ukufudumala kwehlabathi ukuqonda ubuninzi bayo kwaye ngakumbi iipropathi zayo, ezinokuba luncedo kakhulu ekwenzeni umsebenzi wokuphelisa i-CO2 ekhoyo kumoya womhlaba. Phakathi kweempawu ezibalaseleyo eziboniswa yile minerali, umzekelo, khankanya loo nto iyakwazi ukukhulula kunye nokugcina ikhabhon diokside. Elona candelo lililo kukuba, ngokwendalo, kuthatha amawaka eminyaka ukwenza.
Njengesisombululo kwingxaki esingenako ukulinda amawaka eminyaka ukuze kwenziwe izinto ezaneleyo, namhlanje ndifuna ukukubonisa iprojekthi eyenziweyo ethi inikezelwe kuthi ngenqaku elipapashwe liqela labaphandi apho kubhengezwe ukuba, emva kweminyaka yophuhliso, ndikwazile ukufumana indlela yokwenza i-magnesite elabhoratri. Eyona nto inomdla ngale projekthi kukuba, ngokweqela elikhokelwe nguNjingalwazi u-Ian Power, inkqubo efunyenwe liqela lakhe inokufikelela sintering magnesite kakhulu kwaye ngexabiso eliphantsi kakhulu.
Usemninzi umsebenzi ekufuneka wenziwe, nangona ulindelo olubekwe kule teknoloji luphezulu kakhulu
Ukuze angqine ukuba izifundo zakhe zichanekile, kuvavanyo lokuqala olwenziwa kwifayile ye- IYunivesithi yaseTrent (Canada), iye yasetyenziswa njengesixhobo sokuncinanana amanqanaba polystyrene, ezingalahlekiyo kwimveliso yezi zinto, oko kuthetha ukuba zinokusetyenziswa kwakhona kwiinkqubo ezilandelayo. Umbono kukusebenzisa le polystyrene ukuya ukukhawulezisa ukwenziwa kweekristale ze-magnesium carbonate kubushushu obuphantsi ngendlela efanayo nendalo. Umahluko wokwenyani kwindlela indalo kunye neli qela labaphandi abenza ngayo lilele kuphela ngexesha elifunekayo lokuqhuba inkqubo, oko kukuthi, kwindalo ukwenza isixa sezimbiwa eli qela kwiiyure ezingama-72 kuphela, lifuna amakhulu eminyaka.
Njengoko kubhengeziwe ngabaphandi abasebenza kuphuhliso lwale projekthi, okwangoku Basebenza ekucoceni indlela eyimfuneko yokwenza le minerali ngendlela eyenziweyo Nangona sele babhengeze ukuba inkqubo yabo inamathuba amahle okuba sisiseko sokuhluza kunye nokufunxa okusikhulula kumawaka eetoni ze-CO2 namhlanje ezikwiatmosferi yomhlaba kwaye ezingunobangela wobushushu. namhlanje.
