Ukuqhubela phambili kwi-Hybrid Carbon Molecular Sieve Membranes yoKwahlulwa kweGesi okuNgcono

Kwisifundo esiphambili, abaphandi baphumelele ekuveliseni nasekusebenziseni ii-membrane zesihluzo se-carbon molecular molecular ezinee-nano- kunye ne-micro-pores ezilawulwa ngokuchanekileyo, kunye nokufakwa kwee-athomu ze-zinc enye. Le ndlela intsha ithembisa ukuguqula ubuchwepheshe bokwahlulwa kwegesi, inikezela ngophuculo olukhulu ekusebenzeni kakuhle nasekukhetheni.

Uphuhliso lwale mixed membranes luvela kwimfuno ekhulayo yezinto eziphambili ezikwaziyo ukujongana nemingeni ebangelwa ziinkqubo zokwahlula igesi kumashishini ahlukeneyo, kubandakanya amandla, ukhuseleko lokusingqongileyo, kunye nokwenziwa kweekhemikhali. Iindlela zemveli zokwahlula igesi zihlala zixhomekeke kwiinkqubo ezisebenzisa amandla amaninzi, nto leyo ekhokelela kwiindleko eziphezulu zokusebenza kunye neenkxalabo zokusingqongileyo. Ukwaziswa kwemixed carbon molecular sieve membranes kuveza enye indlela ezinzileyo enokunciphisa le micimbi.

Ukwenziwa kwee-membranes kubandakanya inkqubo ecokisekileyo evumela ukulungiswa kakuhle kobukhulu bee-pore kumanqanaba e-nano kunye ne-micro. Oku kuchaneka kubaluleke kakhulu, njengoko kwenza ii-membranes zikwazi ukucoca iigesi ngokukhetha ngokusekelwe kubukhulu bazo beemolekyuli kunye nemilo. Ukufakwa kwee-athomu ze-zinc enye kwisakhiwo se-membrane kuphucula ukusebenza kwayo ngokudala iindawo ezongezelelweyo ezisebenzayo ezenza kube lula ukufunxwa kunye nokwahlukana kwegesi.

Kwiimvavanyo zelebhu, ii-membranes ezixutyiweyo zibonakalise amandla angaqhelekanga okwahlula igesi, ngakumbi kwimixube enzima efana ne-carbon dioxide kunye ne-methane. Ii-membranes zibonakalise ukuvuleka okumangalisayo kunye nokukhetha, ziphumelela ngaphezu kwezixhobo eziqhelekileyo. Oku kubaluleke kakhulu kumxholo wetekhnoloji yokubamba nokugcina i-carbon (CCS), apho ukwahlulwa kwe-CO2 ngokufanelekileyo kwezinye iigesi kubalulekile ekunciphiseni ukukhutshwa kwegesi ezitshisayo.

Ngaphezu koko, ii-membranes ezixutyiweyo zibonisa ithemba kwiindlela ezahlukeneyo ezingaphaya kwe-CCS. Zingasetyenziswa ekucoceni igesi yendalo, kwimveliso ye-hydrogen, nakwishishini lamayeza ukwahlula iikhompawundi ze-organic eziguquguqukayo. Ukuguquguquka kwezi membrane kuvula iindlela ezintsha zophando nophuhliso, ezinokukhokelela kwimpumelelo kumacandelo amaninzi.

Abaphandi banethemba malunga nokukhula kwenkqubo yokwenziwa kwezinto, nto leyo ebalulekileyo ekuqhubekeni korhwebo. Okwangoku bahlola iindlela zokuvelisa ezi membranes ngomlinganiselo omkhulu ngelixa begcina umgangatho kunye neempawu zokusebenza ezibonwa kwiindawo zelebhu. Intsebenziswano namaqabane oshishino nayo iyaqhubeka ukuze kube lula ukutshintsha ukusuka kuphando ukuya kwizicelo ezisebenzayo.

Ukongeza ekusebenzeni kwazo okumangalisayo, ii-membranes zesihluzo se-carbon molecular ze-hybrid nazo zinobuhlobo nokusingqongileyo. Izinto ezisetyenziswa ekuhlanganisweni kwazo zininzi kwaye azinabungozi, zihambelana nokugxininiswa okukhulayo kozinzo kwisayensi yezinto eziphathekayo. Eli candelo linomtsalane ngakumbi kumashishini afuna ukunciphisa umngcipheko wekhabhoni yawo kunye nokunamathela kwimithetho engqongqo yokusingqongileyo.

Njengoko ihlabathi lijongene nemingeni yotshintsho lwemozulu kunye nolawulo lwezixhobo, izinto ezintsha ezifana nee-hybrid carbon molecular sieve membranes zimele inyathelo elibalulekileyo phambili. Ngokuphucula iinkqubo zokwahlulwa kwegesi, ezi membranes zinokudlala indima ebalulekileyo ekufezekiseni izisombululo zamandla acocekileyo kunye nokunciphisa ukukhutshwa komoya kwimizi-mveliso.

Ukuqukumbela, ukwenziwa nokusetyenziswa kwee-membrane ze-hybrid carbon molecular sieve ezine-nano- kunye ne-micro-pores ezilawulwa kakuhle, kunye nee-athomu ze-zinc enye, kubonisa inkqubela phambili ebalulekileyo kwisayensi yezinto eziphathekayo. Ngenxa yamandla azo akhethekileyo okwahlula igesi kunye nokukwazi kwazo ukusetyenziswa ngeendlela ezahlukeneyo, ezi membrane zikulungele ukwenza impembelelo ehlala ixesha elide kumashishini kwihlabathi liphela, zivula indlela yeendlela ezisebenzayo nezizinzileyo. Abaphandi bayaqhubeka nokuphonononga amandla apheleleyo obu buchwepheshe, bejolise ekubuziseni ukusuka kwilebhu ukuya kwizicelo zehlabathi lokwenyani kungekudala.
