Ama-petrochemicals, amakhemisi kanye nokwehlukana kwegesi. Enye yamazwi asetshenziswa kakhulu ama-molecular i-XH-7, eyaziwa ngezakhiwo zayo ezinhle kakhulu ze-adsorption kanye nokuqina okuphezulu okushisayo.

I-XH-7 ama-molelisalar sievesbangama-zeolites zokwenziwa aqukethe inethiwekhi enezici ezintathu yeziteshi ezixhumekile kanye namakheji. Lezi ziteshi zinosayizi ofanayo, okuvumela kuphela ama-molecule ngosayizi othile ukuze adlule. Le mpahla yenza i-XH-7 Inketho enhle kakhulu yezinhlelo zokusebenza ezikhethiwe ze-adsorption, lapho kungasusa khona ukungcola okungafuneki kwingxube.

Ukuqina okuphezulu kwe-XH-7 kungenye inzuzo esemqoka, ukuvumela ukubekezelela amazinga okushisa aphezulu ngaphandle kokulahlekelwa yizakhiwo zayo ze-adsorption. Le mpahla yenza kube kuhle ngezicelo ezidinga ukufudumala, njengokususwa kwamanzi kusuka ku-organic solvents.

Okunye ukusetshenziswa okuvame kakhulu kwama-XH-7 amangqamuzana amangqamuzana kusekuhlanjululweni kwegesi yemvelo. I-XH-7 ingasusa ukungcola okufana namanzi, amakhompiyutha esibabule, kanye nekhabhoni dioxide, okuholela ekusakazweni kwegesi yemvelo ephakeme. Lokhu, nakho, kuholela ekusebenzeni kahle kokuhlangana nokuncishiswa kokuphuma.

Embonini yezemithi, i-XH-7 isetshenziselwa ukuhlanza amakhompiyutha ezidakamizwa futhi isuse ukungcola. Usayizi wayo we-pore afanayo uvumela ukukhethwa kwe-adsorption, ukuqinisekisa ukuthi kuphela i-molecule oyifunayo ithathelwa. Lokhu kuphumela ezimisweni eziphakeme zokuhlanzeka ngemiphumela emibi embalwa.

I-XH-7 ama-molelisalar sievesZiyasetshenziswa nasekukhiqizweni komoya ocebiswe umoya-mpilo, lapho bakhetha khona i-adsorb nitrogen kusuka emoyeni, okuholela ekuqoqweni okuphezulu kwe-oksijini. Lokhu kuyasiza ekusetshenzisweni kwezokwelapha lapho kudingeka khona ukwelashwa kwe-oxygen.

Ngamafuphi, ama-XH-7 ama-molelisalar aseseeves ayingxenye ebalulekile ezimbonini eziningi, enikeza izakhiwo ezinhle kakhulu ze-adsorption, ukuqina okuphezulu, nosayizi wobukhulu obulinganayo. Ukuhlanzwa kwegesi yemvelo ekuhlanjululweni kwemithi yezemithi, XH-7 kudlala indima ebalulekile ekuqinisekiseni ubumsulwa bomkhiqizo kanye nokusebenza kahle.

Uma kukhulunywa ngokukhetha isihlungo se-molecular esilungile sohlelo oluthile, kubalulekile ukucubungula izinto ezifana nosayizi nokwakheka kwama-molecule ukuba ama-adsorbed, izinga lokushisa elisebenzayo, kanye nezinga elidingekayo lobumsulwa.

I-XH-7 ama-molelisalar sievesIba nosayizi we-pore of cishe ama-Angstroms acishe abe ngu-7, ubenza balungele izinhlelo zokusebenza lapho ama-molecule aloluyalu adinga ukuhlukaniswa khona. Baphinde babe nendawo ephezulu yendawo, evumela inani elikhudlwana lamasayithi ama-adsorption, okuholela ekusebenzeni kahle.

Enye inzuzo yama-XH-7 ama-Molelisa weeves ukuqina kwabo okuphezulu kwamakhemikhali. Bangamelana namanani anhlobonhlobo e-PH futhi bamelane nama-degnadation ngama-acid, izisekelo, kanye nezinhlelo ze-organic, zibenze balungele ukusetshenziswa ezindaweni ezinokhahlo.

Ukuqinisekisa ukusebenza kahle kwama-XH-7 ama-molelisalar sieves, kubalulekile ukulandela imihlahlandlela yomenzi yokwenza kusebenze nokuvuselelwa kabusha. Ukwenza kusebenze kubandakanya ukususa noma yimuphi umswakama okhona kuma-sievs, kanti ubuvuleko kubandakanya ukususa noma yimaphi ama-molecule a-adsorbed futhi abuyisele ama-aeeves adsorption.

Ekuphetheni, ama-XH-7 ama-molelisalar aves anikela ngezinzuzo eziningi ngaphezu kwezinye izikhangiso, azikhethele ukukhetha ezimbonini eziningi. Ubukhulu babo bomfaniswano ofanayo, ukuqina okuphezulu okushisayo, kanye nezindawo ezinhle kakhulu ze-adsorption zenza zilungele izinhlelo zokusebenza ezikhethiwe. Ngokukhetha i-HIED ye-Molecular efanelekile yohlelo lokusebenza oluthile futhi kulandela imihlahlandlela yomenzi yokuqalisa nokuvuselelwa kabusha, abasebenzisi bangaqinisekisa ukusebenza kahle kanye nokusebenza kahle.
