sharraxaadda alaabta:
Waxyaabaha ugu muhiimsan ee zeolite-ka malabka ah waa zeolite dabiiciga ah, taas oo ah walxo microporous ah oo aan organic ahayn oo ka kooban SiO2, Al2O3 iyo birta alkaline ama alkaline birta dhulka. Mugga daloolkeeda gudaha wuxuu xisaabiyaa 40-50% wadarta mugga iyo bedkeeda gaarka ah waa 300-1000 m2/g. Waxay leedahay sifooyin caabbinta heerkulka sare, olol la'aanta, xasilloonida kulaylka wanaagsan iyo xasilloonida hydrothermal. Waa shaandho molecular oo tayo sare leh leh oo leh waxqabadka xayeysiinta wanaagsan, ma jirto wasakh sare, waxaana lagu soo celin karaa heerkul sare. Marka la barbardhigo kaarboonka firfircoon ee awllaha malabka ah, waxqabadkiisu waa ilaa 25%. Waxtarka sare, oo si ballaaran loo isticmaalo xayeysiinta, kala-soocidda, catalysis iyo beeraha deegaanka, oo ku habboon mugga hawada weyn, xoojinta gaaska qashinka dabiiciga ah ee hooseeya.
Astaamaha:
1. Xulashada adsorption xoog leh: Shaleefo molecular waxay leedahay cabbir dalool nadiif ah oo isku mid ah waana adsorbent ionic. Sidaa darteed, waxay si xushmad leh u xajin kartaa iyadoo loo eegayo xajmiga iyo polarity ee molecules, waxayna si wax ku ool ah uga saari kartaa ethylene iyo propylene hydrocarbons saturated. Ka saarida acetylene ee ethylene waxaa lagu go'aamiyaa polarity xooggan.
2. Awoodda adsorption xooggan: Xitaa haddii xoogga gaaska ka kooban yahay aad u hooseeya, weli waxay leedahay awoodda xayeysiinta.
3. Aad bay u saamaysay heerkulku walina waxay leedahay awood aad u adsorption ah oo heerkulkeedu sarreeyo, halka xayeysiisyada kale ay si weyn u saameeyaan heerkulka.
Shaleefooyin unugyo unugyo ah oo malabka zeolite waa: shaandhooyin molecular microporous iyo shaandho molecular mesoporous.
(1) Shaandhooyin molecular oo yaryar oo leh dhexroor dalool molecular oo ka yar 2nm iyo 2-50nm waa shaandho molecular mesoporous (ka sarreeya 50nm waa shaandho molecular makroporous). Shaandhooyin molecular Mesoporous waxay leeyihiin meel sare oo gaar ah oo aad u sarreeya, qaab dhismeedka kanaalka caadiga ah oo nidaamsan, qaybinta cabbirka daloolka cidhiidhiga ah, iyo cabbirka daloolka. Sifooyinka cabbirka joogtada ah ee la isku hagaajin karo ayaa ka dhigaya mid adag in la isku dhejiyo oo la kala saaro makromolecules shaandho molecular oo badan oo yar yar. waxayna door muhiim ah ka ciyaaraan falcelinta catalytic.
(2) Marka la dooranayo, alaabta shaandhada molecular ee leh sifooyin kala duwan iyo cabbirada daloolku waa in loo habeeyaa iyadoo loo eegayo qaybaha kala duwan ee gaasta qashinka organic si loo gaaro daawaynta gaaska qashinka dabiiciga ah ee la beegsanayo, buuxiyo shuruudaha, iyo la kulmaan heerarka qiiqa.
Xajmiga shaandhada kelli ee malabka caadiga ah waa 100*100*100mm. Waxaan sidoo kale bixinaa adeegyo gaar ah. Dhawaan, macaamiil ayaa naga soo iibsaday shaandho molecular oo ah 168*168*100mm armaajo malabka ah ee zeolite.
