Kuphononongo olusisiseko, abaphandi baye badibanisa ngempumelelo kwaye basebenzisa i-hybrid carbon molecular sieve membranes ene-nano- kunye ne-micro-pores elawulwa ngokuchanekileyo, kunye nokudityaniswa kwe-athomu enye ye-zinc. Le ndlela intsha ithembisa ukuguqula itekhnoloji yokwahlula igesi, ibonelela ngophuculo olubonakalayo ekusebenzeni nasekukhetheni.
Ukuphuhliswa kwezi membrane ezixubeneyo kubangelwa yimfuno ekhulayo yezinto eziphucukileyo ezikwaziyo ukujongana nemingeni ebangelwa yinkqubo yokwahlula igesi kumashishini ahlukeneyo, kubandakanywa amandla, ukhuseleko lokusingqongileyo, kunye nokuveliswa kweekhemikhali. Iindlela zemveli zokwahlula igesi zihlala zixhomekeke kwiinkqubo zamandla amakhulu, ezikhokelela kwiindleko eziphezulu zokusebenza kunye nokukhathazeka kokusingqongileyo. Ukwaziswa kwe hybrid carbon molecular sieve membranes kubonisa enye indlela ezinzileyo enokunciphisa le miba.
Ukwenziwa kweembrane kubandakanya inkqubo ecokisekileyo evumela ukulungiswa kakuhle kobungakanani bepore kumanqanaba e-nano kunye namancinci. Oku kuchaneka kubalulekile, njengoko kwenza ukuba ii-membrane zihluze ngokukhetha iigesi ngokusekelwe kubungakanani bemolekyuli kunye neemilo. Ukufakwa kwe-athomu ye-zinc enye kwisakhiwo se-membrane kwandisa ngakumbi ukusebenza kwayo ngokudala iindawo ezongezelelweyo ezisebenzayo eziququzelela ukubhengezwa kwegesi kunye nokwahlula.
Kuvavanyo lwaselabhorethri, iimbrane ezixutyiweyo zibonise isakhono esikhethekileyo sokwahlula irhasi, ngakumbi kwimixube ecela umngeni efana nekhabhon diokside kunye nemethane. Iimbumba zibonise ukugqithiswa okuphawulekayo kunye nokukhetha, ukugqithisa izinto eziqhelekileyo. Oku kubaluleke ngakumbi kumxholo wokubamba i-carbon kunye nokugcinwa kobuchwepheshe (CCS) , apho ukuhlukana ngokufanelekileyo kwe-CO2 kwezinye iigesi kubalulekile ekunciphiseni ukukhutshwa kwegesi ye-greenhouse.
Ngapha koko, ii-membrane ezixutyiweyo zibonisa isithembiso kwizicelo ezahlukeneyo ngaphaya kweCCS. Zingasetyenziselwa ukucocwa kwegesi yendalo, imveliso ye-hydrogen, kunye nakwishishini lamachiza ukwahlula iikhompawundi eziguquguqukayo ze-organic. Ukuguquguquka kwezi membrane kuvula iindlela ezintsha zophando kunye nophuhliso, ezinokukhokelela kwimpumelelo kumacandelo amaninzi.
Abaphandi banethemba malunga nokunyuka kwenkqubo yokudibanisa, eyona nto ibalulekileyo kurhwebo. Ngoku baphonononga iindlela zokuvelisa ezi nwebu kumlinganiselo omkhulu ngelixa zigcina umgangatho kunye neempawu zokusebenza eziqatshelwe kwizicwangciso zelebhu. Intsebenziswano namahlakani oshishino nawo ayaqhuba ukuququzelela inguqu ukusuka kuphando ukuya kwizicelo ezisebenzayo.
Ukongeza ekusebenzeni kwabo okumangalisayo, i-hybrid carbon molecular sieve membranes nayo ihambelana nokusingqongileyo. Izinto ezisetyenziswayo kwi-synthesis yazo zininzi kwaye aziyiyo ityhefu, zihambelana nogxininiso olukhulayo lokuzinza kwisayensi yezinto eziphathekayo. Lo mba unomdla ngakumbi kumashishini ajonge ukunciphisa i-carbon footprint kunye nokuthobela imimiselo engqongqo yokusingqongileyo.
Njengoko ihlabathi lizamazamana nemingeni yokutshintsha kwemozulu kunye nolawulo lwezixhobo, izinto ezintsha ezifana ne-hybrid carbon molecular sieve membranes zimele inyathelo elibalulekileyo eliya phambili. Ngokuphucula iinkqubo zokwahlula igesi, ezi membrane zinokudlala indima ebalulekileyo ekuphumezeni izisombululo zamandla acocekileyo kunye nokunciphisa ukukhutshwa kwemizi-mveliso.
Ukuqukumbela, ukudibanisa kunye nokusetyenziswa kwe-hybrid carbon molecular sieve membranes ene-nano- kunye ne-micro-pores elawulwa kakuhle, kunye ne-athom ye-zinc enye, kuphawula inkqubela phambili ebalulekileyo kwisayensi yezinto. Ngobuchule bazo obukhethekileyo bokwahlula irhasi kunye nokubanakho kwezicelo ezahlukeneyo, ezi membrane zikulungele ukwenza impembelelo ehlala ixesha elide kumashishini kwihlabathi liphela, zivula indlela yezenzo ezisebenzayo nezizinzileyo. Abaphandi bayaqhubeka nokuphonononga amandla apheleleyo ale teknoloji, enenjongo yokuyizisa kwibhubhoratri ukuya kwizicelo zehlabathi zangempela kwixesha elizayo.
