Ijeli ye-Alumino silica-AN

Incazelo emfushane:

Ukubonakala kwe-aluminiumi-silica gelinombala ophuzi kancane noma omhlophe obonisa ngale kanye nefomula yekhemikhali yemolekyuli mSiO2 • nAl2O3.xH2O. Izakhiwo zamakhemikhali ezizinzile. Ayishi, ayincibiliki kunoma isiphi isincibilikisi ngaphandle kwesisekelo esiqinile ne-hydrofluoric acid. Uma kuqhathaniswa nejeli ye-silica enezimbobo ezinhle, umthamo wokukhangisa womswakamo ophansi uyafana (ofana no-RH = 10%, RH = 20%), kodwa umthamo wokukhangisa womswakamo ophezulu (ofana no-RH = 80%, RH = 90%) Iphakeme ngo-6-10% kunaleyo yejeli ye-silica ecwebezelayo, kanye nokuzinza okushisayo (350℃) kuphakeme ngo-150 ℃ kunejeli ye-silica enezimbobo ezinhle.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isetshenziswa kakhulu ukuhlukanisa i-hydrocarbon ekhanyayo negesi yemvelo, ukunciphisa indawo yamazolo e-hydrocarbon, futhi ikhiqize igesi yemvelo kanye nophethiloli, okwamanje, igesi yemvelo nayo yomiswa. Uma kuneconsi lamanzi ohlelweni lokuhlukanisa, lidinga cishe u-20% (isilinganiso sesisindo) sejeli ye-Si-Al-silica emelana namanzi njengongqimba oluvikelayo.

Lo mkhiqizo ungasetshenziswa futhi njengento evamilei-desiccant, i-catalyst kanye nomthwali wayo, futhi ingasetshenziswa njenge-PSA, ifaneleka kakhulu izinga lokushisa eliphezulu le-TSA.
