Gcwalisa le fomu ingezantsi kwaye siya kukuthumela nge-imeyile i-PDF inguqulelo ye-PDF ye "Itekhnoloji yeTekhnoloji entsha yokuguqula i-carbon diokside ibe yipetroli ye-fluel"
I-carbon diokside (i-CO2) yimveliso ye-fossil ye-fossil ye-fossil kunye neyona gesi ixhaphakileyo yeGreenhouse, enokuguqulwa ibuye ibuyele kwi-fuels eluncedo. Enye indlela ethembisayo yokuguqula ukukhutshwa kwe-CO2 kwi-Full Storestock yinkqubo ebizwa ngokuba kunciphiswa kokuncitshiswa kwe-elektroniki. Kodwa ukuba ube noluntu, inkqubo kufuneka iphuculwe ukukhetha okanye ukuvelisa iimveliso ezinqwenelekayo zekhabhoni ezinqwenelekayo. Ngoku, njengoko kuchaziwe kwijenali yamandla endalo, uLawrence Berkey Berkey (Berrence BB) sele eyiphucule indlela entsha yokuphucula imeko yobhedu esetyenziselwa ukukhetha inkqubo, ngaloo ndlela ekwandisa ukukhetha inkqubo.
Nangona sisazi ukuba ubhedu yeyona nto iphambili kule mpendulo, ayiboneleli ngokukhetha okuphezulu, "utshilo uAlexis, inzululwazi enkulu kwi-Berkey Lab kunye nonjingalwazi wezobunjineli yeChemics kwiCalifornia, iBerkey. Ukupela utshilo. "Iqela lethu lifumanise ukuba ungasebenzisa imeko yendawo ye-catalyst ukwenza amaqhinga okwahlukeneyo ukubonelela ngolu hlobo lokukhetha."
Kwizifundo zangaphambili, abaphandi basebenzise iimeko ezichanekileyo ukubonelela ngeyona ndawo ibalaseleyo kunye nekhemikhali yokudala iimveliso zekhabhoni ngexabiso lezorhwebo. Kodwa ezi meko zichasene neemeko ezenzeka ngokwemvelo kwiiseli eziqhelekileyo zepetroli kusetyenziswa izixhobo ezenziweyo zamanzi.
Ukwenzela ukumisela uyilo olunokusetyenziswa kwimeko yamanzi e-Fuel, njengenxalenye yeProjekthi yeZiko leZiko leMilukini lamandla engamandla, intsimbi kunye neqela lakhe baguqukela kwimolekyuli (i-ions) ukuba badlule. Ngaphandle kwezinye iion. Ngenxa yeepropathi zabo zokukhetha ezikhethiweyo kakhulu, zilungele kakhulu ukuba nefuthe elinamandla kwi-micronviyanyango.
I-chanyeon kim, umphandi we-postdocler kwiqela lentsimbi kunye nombhali wokuqala wephepha, ocetywayo ukuba awenze i-catalls ye-copersts enesidima esiqhelekileyo esinemigangatho emibini eqhelekileyo, iNafion noSimi. Iqela lenziwe ukuba lenjenjalo kufuneka itshintshe indalo esingqongileyo-kubandakanya i-PH kunye nexabiso lamanzi kunye ne-qubon diokside-nganye yokwalathisa iimveliso ezityebileyo ze-carbon ezinokuguqulwa ngokulula kwiichemicals eziluncedo. Iimveliso kunye neefonti ezingamanzi.
Abaphandi basebenzise ungqameko oluncinci lwe-IOnonomer nganye kunye nomaleko ophindwe kabini kwifilimu yobhedu exhaswa yi-polymer yezinto ezenziwa yifilimu, enokufakwa kufutshane neseli ye-elektroniki. Xa i-carbon diokside kwibhetri kunye nokusebenzisa i-voltage, bayilinganisa itotali yangoku ngebhetri. Emva koko balinganisa igesi kwaye ulwelo oluqokelelwe kwindawo ethe kratya ngexesha lokuphendula. Kwityala le-queder mabini, bafumanisa ukuba iimveliso ezityebileyo zekhabhoni zibalelwa kwi-80% yamandla asetyenzisiweyo yimpendulo-ngaphezulu kwe-60% kwityala elingaziwayo.
"Esi sandwich i-sandwich inika ezona zinto zibalaseleyo zehlabathi: Ukukhetha imveliso ephezulu kunye nomsebenzi ophezulu," watsho uBell. Umhlaba ophindwe kabini awulunganga kuphela kwiimveliso ze-carbon, kodwa uvelisa okwangoku, kwaoko ubonakalisa ukwanda komsebenzi.
Abaphandi bagqiba kwelokuba impendulo ephuculweyo ibiziphumo zoxinzelelo oluphezulu lwe-CO2 oluqokelelweyo kwiCoight ngqo kwi-copper. Ukongeza, iimolekyuli ezingalunganga eziqokelela kwingingqi phakathi kwale mimandla emibini iya kuvelisa i-acidity yasekhaya. Oku kudityaniswa kuhlukumeza i-offiction yorhwebo ethambekele ukuba ivele kwi-IOnomer Iifilimu.
Ukwenzela ukuqhubela phambili ukusebenza kwendlela yokuphendula, abaphandi baguqukele kwitekhnoloji eyahlukileyo eyayingafuneki ifilimu ye-IOnomer njengenye indlela yokwandisa i-CO2 kunye ne-PH: i-voltage. Ngokusebenzisa i-voltage etsaliweyo kwi-Iononomer ephindwe kabini, abaphandi bafumana ukonyuka kwe-250% kwiimveliso ze-carbon kwi-carbon kunye ne-voltage engalunganga.
Nangona abanye abaphengululi bagxile kumsebenzi wabo kuphuhliso lwe-catalysts entsha, ukufunyanwa kwe-catalyst akuthathi nxaxheba kwiimeko zokusebenza. Ukulawula indalo esingqongileyo kwindawo enkulu yindlela entsha neyahlukileyo.
"Asikhange size nesiketata entsha ngokupheleleyo, kodwa sisebenzise ukuqonda kwethu ii-chanetics kwaye sisebenzise olu lwazi ukusikhokela ngendlela yokutshintsha indawo yekati," utshilo uAdam Weber, injineli ephezulu. Izazinzulu kwicandelo leTekhnoloji yamandla kwiBergyley Labotors kunye nombhali wamaphepha.
Inyathelo elilandelayo kukwandisa ukuveliswa kweecawa ezihlanganisiweyo. Uvavanyo lwe-Berkey Lab's Lab's Abliments lubandakanya iinkqubo ezincinci zemodeli, ezazilula kakhulu kunezakhiwo ezinkulu zendawo enkulu efunekayo kwizicelo zentengiso. "Akunzima ukusebenzisa ukungqubana kumgangatho othe tyaba. Kodwa iindlela zorhwebo zinokubandakanya ukuthuthuzela iibhola ezincinci zobhedu," watsho uBell. Ukongeza umaleko wesibini wokudibana kuba ngumceli mngeni. Enye into enokubakho kukuxuba kwaye idipozithi iingubo ezimbini kunye kwi-Solvent, kwaye ithemba lokuba bayahlulahlula i-Solvent xa inyibiliki iphume. Kuthekani ukuba aba? I-Bell iqukunjelwe: "Kufuneka nje sibe nobulumko." Jonga kwi-kim c, i-bui jc, luo x kunye nabanye. I-micronvialvaly micronvialvialvaoly ye-electrone ye-electrong ye-CO2 kwiimveliso zekhabhoni ezininzi zisebenzisa i-IOnomer i-Ionomer i-Ionomer Coating kwi-Copper.
