Va'aiga lautele o alumina fa'agaoioia
Alumina fa'agaoioia, e ta'ua fo'i o le activated bauxite, e ta'ua o le alumina fa'agaoioia ile Igilisi. Alumina faʻaaogaina i faʻamalosi e masani ona taʻua o le "alumina faʻagaoioia". O se mea fa'apolopolo, mafolafola tele mea mautu ma se fa'afanua tele. O lona microporous luga o loʻo i ai uiga e manaʻomia mo catalysis, e pei o le adsorption performance, galuega i luga o le fogaeleele, faʻamautu lelei vevela, ma isi mea, o lea e faʻaaogaina lautele e avea o se catalyst ma catalyst carrier mo gaioiga faʻamaʻi.
O le spherical activated alumina pressure swing oil adsorbent o pa'epa'e spherical porous particles. O le alumina fa'aagaoioia o lo'o i ai le lapo'a tutusa, lamolemole, maualuga le malosi fa'ainisinia, malosi hygroscopicity, e le fulafula ma ta'e pe a uma le vai, ma tumau e le suia. E le o'ona, leai se manogi, ma e le mafai ona fa'afefe i le vai ma le ethanol.
Alumina
E le mafai ona soloia i le vai ma e mafai ona solo malie i le sulfuric acid. E mafai ona faʻaaogaina e faʻamamaina ai le alumini uʻamea ma o se mea mataʻutia foi mo le faia o faʻamau, porcelain, mea faʻafefe ma maʻa maʻa.
Alumina fa'aaogaina e pei o le adsorbent, catalyst ma catalyst carrier ua ta'ua o le "activated alumina". O loʻo i ai uiga o le porosity, faʻasalalau maualuga ma le tele o mea faʻapitoa. E faʻaaogaina lautele i togafitiga vai, petrochemical, vailaʻau lelei, meaola ma vailaʻau.
Uiga o le alumina
1. Fa'afanua fa'apitoa tele: alumina fa'aagaoioia o lo'o i ai se tulaga maualuga maualuga. E ala i le pulea lelei o le sintering system o alumina, alumina faʻagaoioia ma se vaega faʻapitoa i luga o le maualuga e pei o le 360m2 / G e mafai ona saunia. O le alumina fa'aagaoioia saunia e ala i le fa'aogaina o le alumini alumini hydroxide fa'apalapala e le NaAlO2 e pei o mea mata e la'ititi la'ititi lapo'a ma se vaega fa'apitoa e maualuga e 600m2 / g.
2. Faʻatulagaina le tele o le pore size: I se tulaga masani, o oloa e iai le lapoʻa lapoʻa e mafai ona saunia e ala i le taoina i le alumini hydroxide mama. E mafai ona saunia mea laiti pore size e ala i le saunia o alumina fa'agaoioia ma kelu alumini, ma isi mea a'o alumina fa'agaoioia pore lapoa e mafai ona saunia e ala i le fa'aopoopoina o nisi o mea fa'aola, e pei o le ethylene glycol ma le fiber, pe a uma le mu.
3. O le pito i luga e acidic ma e lelei le mautu vevela.
Galuega ole alumina fa'agaoioia
Alumina fa'agaoioia o lo'o i totonu o le vaega o alumina vaila'au, lea e masani ona fa'aaogaina e pei o le adsorbent, fa'amamā vai, fa'apipi'i ma fa'apipi'i. O le alumina fa'agaoioia e iai le malosi e filifili fa'apipi'i vai i le kesi, vai ausa ma nisi vai. A maeʻa ona tumu le adsorption, e mafai ona vevela ile 175-315. D ioe. Adsorption ma reactivation e mafai ona faia i le tele o taimi.
I le faaopoopo atu i le faaaogaina o se desiccant, e mafai foi ona mitiia lubricating ausa suauu mai le okesene faaleagaina, hydrogen, carbon dioxide, kasa faalenatura, ma isi. Ma e mafai ona faaaoga e avea o se catalyst ma catalyst lagolago ma o se lagolago mo le auiliiliga chromatographic.
E mafai ona faʻaaogaina e avea o se mea faʻafefeteina mo vai inu maualuga fluorine (faʻatasi ai ma le tele o le defluorinating gafatia), o se mea faʻafefeteina mo alkanes faʻasalalau i le gaosiga o le alkylbenzene, o se sui faʻafefeteina ma toe faʻafouina mo le suauʻu transformer, o se mea faʻagogo mo kesi i le gaosiga o le okesene. , alamanuia ie ma alamanuia faaeletonika, o se mea faamago mo le ea otometi meafaigaluega, ma se mea e faamago ai ma se faamama faamama i vailaau vailaau, faamago petrochemical ma isi alamanuia.
