An cimma gagarumin ci gaba a fannin kayan shaye-shaye ta hanyar inganta sinadarin Low-Silica X (LSX) zeolite, wani sieve na kwayoyin halitta na zamani wanda aka shirya don sauya tsarin shaye-shayen iskar gas (PSA) don samar da iskar oxygen da sauran rabuwar iskar gas.
Zeolites na gargajiya, aluminosilicates na crystalline tare da daidaitattun tsarin ramuka, sune manyan hanyoyin aiki a cikin rabuwa da tsarkakewa na masana'antu. Zeolite NaX (13X) da ake amfani da shi sosai, tare da rabon silicon-zuwa-aluminum (Si/Al) na 1-1.5, shine ma'auni don shaƙar nitrogen daga iska. Sabon zeolite na LXS mai kyau yana tura wannan iyaka ta hanyar cimma rabon Si/Al ƙasa da 1.0, wanda ya kai iyakar ka'idar tsarin zeolite X.
Wannan sinadarin silica mai ƙarancin ƙarfi yana ƙara yawan cations na sodium masu daidaita caji a cikin ramuka sosai. Waɗannan cations suna ƙirƙirar wuraren hulɗar lantarki masu ƙarfi, suna haɓaka kusancin abu ga ƙwayoyin quadrupolar kamar nitrogen (N₂). Saboda haka, LXS yana nuna ƙarfin shaye-shayen nitrogen da zaɓi mai kyau fiye da iskar oxygen (O₂) idan aka kwatanta da takwaransa na 13X na yau da kullun.
"LXS tana wakiltar wani ci gaba na kimiyyar kayan abu ga fasahar shanyewa," in ji Dr. [Name na Almara], babban mai bincike a Cibiyar Kayan Aiki ta Advanced Materials. "Ta hanyar haɓaka abubuwan da ke cikin aluminum a cikin tsarin FAU, mun ƙera siminti mai mafi girman yawan wuraren aiki. Wannan yana fassara kai tsaye zuwa ingantaccen samar da iskar oxygen, yana ba da damar adana makamashi mai yawa da kuma tsarkake samfura a cikin tsarin PSA."
Kimanta ayyukan da aka yi masu zaman kansu sun tabbatar da cewa iskar oxygen da aka samar ta hanyar na'urorin PSA na LXS na iya samun tsafta fiye da kashi 95% tare da ingantaccen saurin murmurewa. Wannan ya sa fasahar ta zama mai kyau musamman ga samar da iskar oxygen ta likitanci, wuraren tsaftace ruwan shara da ke buƙatar ingantaccen iska, da kuma hanyoyin ƙarfe da sinadarai daban-daban.
Bayan samar da iskar oxygen, yanayin LXS zeolite mai wadataccen cation yana buɗe hanyoyin bincike masu kyau don raba wasu, gami da kama carbon dioxide daga iskar gas da tsarkake kwararar hydrogen.
Masana'antun kasuwanci sun lura cewa haɗakar LXS, duk da cewa tana buƙatar ingantaccen iko, ana iya daidaita ta ta amfani da hanyoyin hydrothermal da aka kafa. Kayan yana riƙe da kyakkyawan ƙarfin injiniya da halayyar kwanciyar hankali na zeolites na roba, yana tabbatar da aiki mai ƙarfi a cikin ayyukan PSA mai zagaye.
Ana sa ran gabatar da LXS zeolite mai inganci zai hanzarta ɗaukar fasahar PSA a matsayin madadin distillation mai ƙarfi da ake buƙata don samar da iskar oxygen, wanda hakan zai ba da gudummawa ga samar da iskar gas ta masana'antu mai sassauƙa da rarrabawa.
Game da Zeolites:
Zeolites ma'adanai ne masu ƙananan ramuka waɗanda ake amfani da su azaman masu shaye-shaye da masu haɓaka sinadarai. Girman ramukan su iri ɗaya yana ba su damar raba ƙwayoyin halitta bisa ga girma da polarity, wanda hakan ke sa su zama dole a masana'antar sinadarai, sinadarai, da muhalli.
