Intuthuko ku-Hybrid Carbon Molecular Sieve Membrane Yokuhlukaniswa Kwegesi Okuthuthukisiwe

Esifundweni esishaqisayo, abacwaningi baphumelele ukuhlanganisa nokusebenzisa ama-membrane esivikelo se-carbon molecular ahlanganisiwe anezimbobo ezincane nezincane ezilawulwa ngokunembile, kanye nokufakwa kwama-athomu e-zinc eyodwa. Le ndlela entsha ithembisa ukuguqula ubuchwepheshe bokuhlukanisa igesi, inikeze intuthuko enkulu ekusebenzeni kahle nasekukhetheni.

Ukuthuthukiswa kwalezi zindwangu ezixubile kuvela ekwandeni kwesidingo sezinto ezithuthukisiwe ezikwazi ukubhekana nezinselele ezibangelwa izinqubo zokuhlukanisa igesi ezimbonini ezahlukene, okuhlanganisa amandla, ukuvikelwa kwemvelo, kanye nokukhiqizwa kwamakhemikhali. Izindlela zendabuko zokuhlukanisa igesi zivame ukuthembela ezinqubweni ezidinga amandla amaningi, okuholela ezindleleni zokusebenza eziphezulu kanye nokukhathazeka kwemvelo. Ukwethulwa kwezindwangu zesivikelo se-carbon molecular hybrid kuveza enye indlela eqhubekayo enganciphisa lezi zinkinga.

Ukwenziwa kwama-membrane kuhilela inqubo ecophelelayo evumela ukulungiswa kahle kobukhulu be-pore emazingeni e-nano kanye nama-micro. Lokhu kunemba kubalulekile, njengoba kwenza ama-membrane akwazi ukuhlunga amagesi ngokukhetha ngokusekelwe kobukhulu bawo bama-molecule kanye nokuma kwawo. Ukufakwa kwama-athomu e-zinc eyodwa esakhiweni se-membrane kuthuthukisa ukusebenza kwayo ngokudala izindawo ezengeziwe ezisebenzayo ezenza kube lula ukumuncwa nokuhlukaniswa kwegesi.

Ekuhlolweni kwelabhorethri, ama-membrane ahlanganisiwe abonise amakhono ahlukile okuhlukanisa igesi, ikakhulukazi ezingxubeni eziyinselele njenge-carbon dioxide ne-methane. Ama-membrane abonise ukuvuleka okuphawulekayo nokukhetha, enza kahle kakhulu kunezinye izinto ezivamile. Lokhu kubaluleke kakhulu kumongo wobuchwepheshe bokubamba nokugcina i-carbon (CCS), lapho ukuhlukaniswa kwe-CO2 kahle kwamanye amagesi kubalulekile ekunciphiseni ukukhishwa kwegesi ebamba ukushisa.

Ngaphezu kwalokho, ama-membrane ahlanganisiwe abonisa ithemba ezinhlotsheni ezahlukene ngaphandle kwe-CCS. Angasetshenziswa ekuhlanzweni kwegesi yemvelo, ekukhiqizweni kwe-hydrogen, ngisho nasembonini yemithi yokuhlukanisa amakhemikhali e-organic aguquguqukayo. Ukuguquguquka kwala ma-membrane kuvula izindlela ezintsha zocwaningo nentuthuko, okungaholela ekuthuthukisweni kwemikhakha eminingi.

Abacwaningi banethemba ngokwandiswa kwenqubo yokwenziwa, okuyisici esibalulekile ekusebenzeni kahle kwezentengiselwano. Njengamanje bahlola izindlela zokukhiqiza lawa ma-membrane ngezinga elikhulu ngenkathi begcina ikhwalithi kanye nezici zokusebenza ezibonwa ezindaweni zelebhu. Ukubambisana nabalingani bemboni nakho kuyaqhubeka ukuze kube lula ukushintsha kusuka ocwaningweni kuya ezisetshenzisweni ezisebenzayo.

Ngaphezu kokusebenza kwazo okumangalisayo, ama-membrane esivikelo se-carbon molecular hybrid nawo anobungani nemvelo. Izinto ezisetshenziswa ekuhlanganisweni kwawo ziningi futhi azinabo ubuthi, okuhambisana nokugcizelela okukhula kokusimama kwesayensi yezinto ezibonakalayo. Lesi sici sikhanga kakhulu izimboni ezifuna ukunciphisa ukunyatheliswa kwazo kwekhabhoni nokunamathela emithethweni eqinile yezemvelo.

Njengoba umhlaba ubhekene nezinselele zokushintsha kwesimo sezulu kanye nokuphathwa kwezinsiza, izinto ezintsha ezifana ne-hybrid carbon molecular sieve membranes zimelela isinyathelo esibalulekile sokuqhubekela phambili. Ngokuthuthukisa izinqubo zokuhlukanisa igesi, lezi zinhlaka zingadlala indima ebalulekile ekufezeni izixazululo zamandla ahlanzekile kanye nokunciphisa ukukhishwa kwegesi ezimbonini.

Ekuphetheni, ukuhlanganiswa nokusetshenziswa kwe-hybrid carbon molecular sieve membranes ene-nano- kanye ne-micro-pores elawulwa kahle, kanye nama-athomu e-single zinc, kuphawula intuthuko enkulu kwisayensi yezinto ezibonakalayo. Ngamakhono awo ahlukile okuhlukanisa igesi kanye nekhono lokusetshenziswa okuhlukahlukene, la ma-membrane alungele ukwenza umthelela ohlala njalo ezimbonini emhlabeni jikelele, evula indlela yemikhuba ephumelelayo neqhubekayo. Abacwaningi bayaqhubeka nokuhlola amandla aphelele alobu buchwepheshe, behlose ukuwuletha kusuka elabhorethri uye ezisetshenzisweni zangempela esikhathini esizayo esiseduze.
