Ijeli ye-alumino silica-AN

Inkcazelo emfutshane:

Ukubonakala kwe-aluminiyamijeli yesilikaityheli kancinane okanye imhlophe ibe sobala kunye nefomula yekhemikhali yemolekyuli mSiO2 • nAl2O3.xH2O. Iimpawu zeekhemikhali ezizinzileyo. Ukungatsha, akunyibiliki nakwesiphi na isinyibilikisi ngaphandle kwesiseko esomeleleyo kunye ne-hydrofluoric acid. Xa kuthelekiswa nejeli ye-silica ecolekileyo, umthamo we-adsorption womswakama ophantsi uyafana (ufana ne-RH = 10%, i-RH = 20%), kodwa umthamo we-adsorption wokufuma okuphezulu (okufana ne-RH = 80%, i-RH = 90%). I-6-10% ephezulu kune-gel ye-silica ecocekileyo, kunye nokuzinza kwe-thermal (350℃) yi-150 ℃ ephezulu kune-gel ye-silica ecocekileyo.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Isetyenziselwa ikakhulu ukwahlula i-hydrocarbon ekhanyayo kwigesi yendalo, ukunciphisa indawo yombethe ye-hydrocarbon, kunye nokuvelisa igesi yendalo kunye negesi, okwangoku, igesi yendalo yomile. Ukuba kukho i-droplet yamanzi kwinkqubo yokwahlula, idinga malunga ne-20% (umlinganiselo wobunzima) we-gel-resistant Si-Al-silica gel njengomaleko okhuselayo.

Le mveliso ingasetyenziselwa njengento eqhelekileyodesiccant, i-catalyst kunye nomthwali wayo, nayo ingasetyenziswa njenge-PSA, ilungele kakhulu ubushushu obuphezulu be-TSA.
