Kuye kwaphunyezwa inkqubela phambili ebalulekileyo kwizinto ezifunxayo ngokusebenzisa i-Low-Silica X (LSX) zeolite, isihluzo seemolekyuli sesizukulwana esilandelayo esilungele ukuguqula iinkqubo ze-pressure swing adsorption (PSA) zokuvelisa ioksijini kunye nezinye iindlela zokwahlulahlula igesi.
Ii-zeolite zemveli, ii-crystalline aluminosilicates ezinezakhiwo ezichanekileyo ze-pore, zizinto ezisebenzayo ekuhlukaniseni nasekucoceni imboni. I-NaX (13X) zeolite esetyenziswa kakhulu, enomlinganiselo we-silicon-to-aluminium (Si/Al) we-1-1.5, luphawu lokulinganisa ukufunxwa kwe-nitrogen emoyeni. I-LXS zeolite esandul’ ukwenziwa ityhala lo mda ngakumbi ngokufikelela kumlinganiselo we-Si/Al ophantsi njenge-1.0, ifikelela kumda wethiyori wesakhiwo sesakhelo se-zeolite X.
Olu lwakhiwo lwe-silica oluphantsi kakhulu lunyusa kakhulu inani le-sodium cations ezilinganisa itshaja ngaphakathi kwee-pores. Ezi cations zenza iindawo zokunxibelelana ze-electrostatic eziqinileyo, ziphucula kakhulu ukunamathelana kwezinto kwiimolekyuli ezine-quadrupolar ezifana ne-nitrogen (N₂). Ngenxa yoko, i-LXS ibonisa amandla aphezulu kakhulu okufunxa i-nitrogen kunye nokukhetha ngaphezu kwe-oxygen (O₂) xa kuthelekiswa ne-13X counterpart yayo eqhelekileyo.
“I-LXS imele inkqubela phambili kwisayensi yezinto eziphathekayo kwitekhnoloji yokufunxa,” utshilo uGqr. [Fictional Name], umphandi ophambili kwi-Advanced Materials Institute. “Ngokwandisa umxholo we-aluminiyam kwisakhelo se-FAU, senze isihluzo esinobuninzi obukhulu beendawo ezisebenzayo. Oku kuthetha ngokuthe ngqo kwimveliso yeoksijini esebenza kakuhle, enika amandla okonga amandla amakhulu kunye nobunyulu bemveliso obuphezulu kwiinkqubo ze-PSA.”
Uvavanyo oluzimeleyo lokusebenza luqinisekisa ukuba ioksijini eveliswa ngeeyunithi ze-PSA ezisekwe kwi-LXS inokufezekisa ubumsulwa obungaphezulu kwe-95% ngamanqanaba okubuyisela aphuculweyo. Oku kwenza le teknoloji ibe nomtsalane kakhulu kubonelelo lweoksijini yezonyango oluphakathi, izibonelelo zonyango lwamanzi amdaka ezifuna umoya osebenzayo, kunye neenkqubo ezahlukeneyo zesinyithi kunye neekhemikhali.
Ngaphaya kokuveliswa kweoksijini, indawo ekhethekileyo etyebileyo kwi-cation ye-LXS zeolite ivula iindlela zophando ezithembisayo zokwahlulwahlulwa kwezinye izinto, kubandakanya ukubanjwa kwekhabhoni diokside kwiigesi zeflue kunye nokucocwa kwemijelo yehydrogen.
Abavelisi bezorhwebo baqaphela ukuba ukwenziwa kwe-LXS, nangona kufuna ulawulo oluchanekileyo, kunokwandiswa kusetyenziswa iindlela ezisetyenzisiweyo ze-hydrothermal. Ezi zinto zigcina amandla oomatshini abalaseleyo kunye nozinzo oluphawu lwe-zeolites zokwenziwa, ziqinisekisa ukusebenza okuqinileyo kwimisebenzi ye-cyclic PSA.
Ukwaziswa kwe-LXS zeolite esebenza kakhulu kulindeleke ukuba kukhawulezise ukwamkelwa kwetekhnoloji ye-PSA njengendlela ethembekileyo, efunekayo endaweni ye-cryogenic distillation yokubonelela ngeoksijini, nto leyo enegalelo kwimveliso yegesi yemizi-mveliso eguquguqukayo neyahlulwe ngokweemfuno zabantu.
Malunga namaZeolite:
IiZeolite ziiminerali ezinemibhobho emincinci ezisetyenziswa kakhulu njengee-adsorbents kunye nee-catalysts. Ubungakanani bazo obufanayo bemibhobho buzivumela ukuba zahlule iimolekyuli ngokusekelwe kubukhulu kunye ne-polarity, nto leyo ezenza zibe yimfuneko kakhulu kumashishini eekhemikhali, e-petrochemical, kunye nendalo esingqongileyo.
