amakhemikhali e-petrochemicals, i-pharmaceuticals, kanye nokuhlukaniswa kwegesi. Esinye sezisefo ze-molecular ezisetshenziswa kakhulu yi-XH-7, eyaziwa ngezindawo zayo ezinhle kakhulu zokukhangisa kanye nokuzinza okuphezulu kwe-thermal.

Izisefo ze-molecular XH-7ama-zeolite okwenziwa aqukethe inethiwekhi enezinhlangothi ezintathu zamashaneli axhumene namakheji. Lawa mashaneli anosayizi ofanayo, ovumela kuphela ama-molecule osayizi othize ukuba adlule kuwo. Lesi sakhiwo senza i-XH-7 ibe yisinqumo esihle kakhulu sezinhlelo zokusebenza ezikhethiwe ze-adsorption, lapho ingasusa khona ukungcola okungafuneki kwingxube.

Ukuzinza okuphezulu kwe-thermal kwe-XH-7 kungenye inzuzo ebalulekile, eyivumela ukuthi imelane namazinga okushisa aphezulu ngaphandle kokulahlekelwa izici zayo ze-adsorption. Lesi sakhiwo sikwenza kube kuhle ezinhlelweni ezidinga ukushisisa, njengokususwa kwamanzi kuzincibilikisi zemvelo.

Enye yezindlela ezivame ukusetshenziswa kakhulu ze-XH-7 ze-molecular sieves ekuhlanzweni kwegesi yemvelo. I-XH-7 ingasusa ukungcola okunjengamanzi, izinhlanganisela zesulfure, ne-carbon dioxide, okuholela ekuhlanzekeni okuphezulu kokugeleza kwegesi yemvelo. Lokhu, futhi, kuholela ekusebenzeni okuthuthukisiwe komlilo kanye nokunciphisa ukukhishwa kwekhabhoni.

Embonini yemithi, i-XH-7 isetshenziselwa ukuhlanza izinhlanganisela zezidakamizwa nokususa ukungcola. Ubukhulu bayo bembotshana obufanayo buvumela ukukhangiswa okukhethekile, okuqinisekisa ukuthi kubanjwa i-molecule efunwayo kuphela. Lokhu kubangela izidakamizwa ezihlanzekile ezinemiphumela emibi embalwa.

Izisefo ze-molecular XH-7zibuye zisetshenziswe ekukhiqizeni umoya ocebile komoya-mpilo, lapho zikhetha khona i-nitrogen emoyeni, okuholela ekuhlanganiseni okuphezulu komoyampilo. Lokhu kuyasiza ekusetshenzisweni kwezokwelapha lapho kudingeka ukwelashwa komoyampilo.

Kafushane, ama-XH-7 ama-molecular sieves ayingxenye ebalulekile ezimbonini eziningi, ahlinzeka ngezakhiwo ezinhle kakhulu ze-adsorption, ukuzinza okuphezulu kwe-thermal, kanye nobukhulu obufanayo be-pore. Kusukela ekuhlanzweni kwegesi yemvelo kuya ekuhlanzweni kwezidakamizwa zemithi, i-XH-7 idlala indima ebalulekile ekuqinisekiseni ukuhlanzeka komkhiqizo nokusebenza kahle.

Uma kuziwa ekukhetheni isisefo se-molecular esifanele sohlelo lokusebenza oluthile, kubalulekile ukucabangela izici ezifana nosayizi nokuma kwama-molecule azokhangiswa, izinga lokushisa elisebenzayo, nezinga elidingekayo lokuhlanzeka.

Izisefo ze-molecular XH-7abe nosayizi wembotshana cishe ama-angstrom ayi-7, okuwenza afanelekele ukusetshenziswa lapho ama-molecule alo sayizi adinga ukuhlukaniswa. Futhi banendawo ephezulu, evumela inani elikhulu lezingosi ze-adsorption, okuholela ekusebenzeni okuthuthukisiwe.

Enye inzuzo ye-XH-7 ye-molecular sieves ukuzinza kwabo kwamakhemikhali aphezulu. Angakwazi ukumelana nenani elibanzi le-pH futhi amelane nokucekelwa phansi ngama-asidi, izisekelo, nezincibilikizi eziphilayo, akwenze afanelekele ukusetshenziswa ezindaweni ezinokhahlo.

Ukuqinisekisa ukusebenza kahle kwezisefo zamamolekyuli e-XH-7, kubalulekile ukulandela imihlahlandlela yomkhiqizi ukuze isebenze futhi yenziwe kabusha. Ukwenza kusebenze kuhilela ukususa noma imuphi umswakama okhona kuzisefo, kuyilapho ukukhiqizwa kabusha kuhilela ukususa noma imaphi ama-molecule akhangisiwe kanye nokubuyisela izici zokukhanga zezisefo.

Sengiphetha, izisefo ze-XH-7 zamangqamuzana zinikeza izinzuzo eziningi ngaphezu kwezinye izikhangisi, okuzenza zibe yisinqumo esithandwayo ezimbonini eziningi. Usayizi wabo wezimbotshana ezifanayo, ukuzinza okuphezulu kwe-thermal, kanye nezakhiwo ezinhle kakhulu zokukhanga zizenza zilungele izinhlelo zokusebenza zokuhlukanisa ezikhethiwe. Ngokukhetha isisefo se-molecular esifanele sohlelo lokusebenza oluthile nokulandela imihlahlandlela yomkhiqizi yokuvula nokuvuselela, abasebenzisi bangaqinisekisa ukusebenza kahle nokusebenza kahle.
