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 kokushisa.

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-molecular XH-7 zinikeza izinzuzo eziningi ngaphezu kwezinye izikhangisi, okuzenza zibe yisinqumo esithandwayo ezimbonini eziningi.Usayizi wabo wembotshana ofanayo, ukuqina okushisayo okuphezulu, kanye nezakhiwo ezinhle kakhulu zokukhanga kubenza balungele izinhlelo zokusebenza zokuhlukanisa ezikhethiwe.Ngokukhetha isisefo semolekyuli esifanele sohlelo lokusebenza oluthile nokulandela imihlahlandlela yomkhiqizi yokuvula nokuvuselela, abasebenzisi bangaqinisekisa ukusebenza kahle nokusebenza kahle.
