- Fa'amatalaga
- Alumini oxide o loʻo faʻaaogaina e pei o le desiccant, adsorbent, catalyst ma catalyst carrier e taʻua o le "Activated alumina", o loʻo i ai porous, faʻasalalau maualuga ma faʻaputuina tele, ma e faʻaaogaina lautele i le fanua o petrochemical, vailaʻau lelei, meaola ma vailaʻau.
- Fa'agaoioi alumina e masani lava ona faia e alumini hydroxide fa'avevela ma fa'amama.O le alumini hydroxide e lauiloa foi o le hydrated aluminum oxide, ma o lona vailaʻau o le Al2O3· nH2O, e masani ona ese i le numera o vai tioata o loʻo i ai.A maeʻa le faʻavevelaina o le alumini hydroxide ma faʻamago, e mafai ona mauaρ-Al2O3.
- Fa'atatauga
- Alumina fa'agaoioia o lo'o i totonu o le vaega o alumina vaila'au, e masani ona fa'aaogaina mo desiccant, adsorbent, vai fa'amama vai, fa'amalama ma fa'aulu.Alumina fa'agaoioia o lo'o i ai le adsorption filifilia o kasa, vai vai ma nisi vai.O le adsorption saturation e mafai ona toe faʻaolaina e ala i le faʻamafanafanaina ma le aveeseina o le vai ile 175 ~ 315 ℃.E mafai ona faia le tele o adsorption ma desorption.
- E ese mai le avea o se desiccant, e mafai foi ona mitiia ausa lubricant mai le okesene faaleagaina, hydrogen, carbon dioxide, kasa masani ma isi.E mafai ona fa'aaogaina e pei o le fa'apipi'i ma le ta'avale fa'ama'i ma le va'aiga o le au'ili'ili lanu lanu.E mafai ona faʻaaogaina e pei o le maualuga o le fluorine vai inu (tele fluorine gafatia), defluoride o le alkane faʻasalalau i alkylbenzene gaosiga, deacid regenerating sui o le suauʻu suauʻu, faʻamago kasa i le okesene alamanuia, pisinisi ie, alamanuia faaeletonika, matagi meafaigaluega otometi, faʻamago sui i vailaʻau. fetila'i, fa'agogo petrochemical, fa'amama fa'amama (sau e o'o atu i le-40 ℃), ma le fesuisuia'i o le mamafa o le sau adsorption e o'o atu i le-55 ℃ i le alamanuia vavae'esega.Ose vaila'au fa'amago e sili ona lelei ma fa'agogo loloto le vai.E fetaui lelei mo iunite faʻafouina e leai se vevela.
