Kuye kwafinyelelwa intuthuko enkulu ezintweni ezifaka i-adsorbent ngokusebenzisa i-Low-Silica X (LSX) zeolite, isihlungo sama-molecule sesizukulwane esilandelayo esilungele ukuguqula izinqubo ze-pressure swing adsorption (PSA) zokukhiqizwa komoya-mpilo kanye nokunye ukuhlukaniswa kwegesi.
Ama-zeolite endabuko, ama-aluminosilicates ekristalu anezakhiwo eziqondile ze-pore, ayizingcweti ekuhlukaniseni nasekuhlanzeni izimboni. I-zeolite ye-NaX (13X) esetshenziswa kabanzi, enesilinganiso se-silicon-to-aluminium (Si/Al) esingu-1-1.5, iyisilinganiso sokumuncwa kwe-nitrogen emoyeni. I-zeolite ye-LXS esanda kuqedwa iqhubekisela phambili lo mngcele ngokufeza isilinganiso se-Si/Al esiphansi njengo-1.0, ifinyelela umkhawulo wethiyori wesakhiwo sohlaka lwe-zeolite X.
Lokhu kwakheka kwe-silica okuphansi kakhulu kwandisa kakhulu inani lama-sodium cations alinganisa ukushaja ngaphakathi kwama-pores. Lawa ma-cation adala izindawo zokuxhumana eziqinile ze-electrostatic, okuthuthukisa kakhulu ukunamathela kwezinto kuma-molecule ama-quadrupolar njenge-nitrogen (N₂). Ngenxa yalokho, i-LXS ikhombisa amandla aphezulu kakhulu okumunca i-nitrogen kanye nokukhetha ngaphezu kwe-oxygen (O₂) uma kuqhathaniswa nomlingani wayo ojwayelekile we-13X.
“I-LXS imelela intuthuko yesayensi yezinto ezibonakalayo kwezobuchwepheshe bokumunca,” kusho uDkt. [Fictional Name], umcwaningi oholayo e-Advanced Materials Institute. “Ngokwandisa okuqukethwe kwe-aluminium ohlakeni lwe-FAU, sakhe isihlungo esinobuningi obukhulu kakhulu bezindawo ezisebenzayo. Lokhu kuhumushela ngqo ekukhiqizweni komoya-mpilo okusebenza kahle, okunikeza amandla okonga amandla amakhulu kanye nokuhlanzeka okuphezulu komkhiqizo ezinhlelweni ze-PSA.”
Ukuhlolwa kokusebenza okuzimele kuqinisekisa ukuthi i-oxygen ekhiqizwa ngamayunithi e-PSA asekelwe ku-LXS ingafinyelela ukungcola okungaphezu kuka-95% ngamazinga okululama athuthukisiwe. Lokhu kwenza ubuchwepheshe bukhange kakhulu ekuhlinzekweni kwe-oxygen yezokwelapha okuphakathi nendawo, izikhungo zokwelashwa kwamanzi amdaka ezidinga umoya osebenzayo, kanye nezinqubo ezahlukahlukene zensimbi kanye namakhemikhali.
Ngaphandle kokukhiqizwa komoya-mpilo, indawo eyingqayizivele ecebile nge-cation ye-LXS zeolite ivula izindlela zocwaningo ezithembisayo zokuhlukaniswa kwezinye izinto, okuhlanganisa ukuthunjwa kwe-carbon dioxide emagesi aphuma emanzini kanye nokuhlanzwa kwemifudlana ye-hydrogen.
Abakhiqizi bezentengiselwano baphawula ukuthi ukwenziwa kwe-LXS, yize kudinga ukulawulwa okuqondile, kungandiswa kusetshenziswa izindlela ezisetshenzisiwe zokushisa kwamanzi. Izinto zigcina amandla amahle kakhulu okusebenza kanye nokuzinza kwezimpawu ze-zeolite zokwenziwa, okuqinisekisa ukusebenza okuqinile ekusebenzeni kwe-PSA okujikelezayo.
Ukwethulwa kwe-zeolite ye-LXS esebenza kahle kulindeleke ukuthi kusheshise ukwamukelwa kobuchwepheshe be-PSA njengendlela ethembekile, edingekayo esikhundleni se-cryogenic distillation yokuhlinzekwa komoya-mpilo, okunegalelo ekukhiqizweni kwegesi yezimboni eguquguqukayo futhi ehlukaniswe kakhulu.
Mayelana namaZeolite:
Ama-Zeolite angamaminerali amancane anezimbobo ezincane avame ukusetshenziswa njenge-adsorbents kanye ne-catalysts. Ubukhulu bawo obufanayo be-pore buwavumela ukuthi ahlukanise ama-molecule ngokusekelwe kusayizi kanye ne-polarity, okwenza abe yinto ebalulekile embonini yamakhemikhali, ye-petrochemical, kanye neyezemvelo.
