Gel ya silica ya Alumino–AN Chithunzi Chodziwika

Alumino silica gel–AN

Kufotokozera Kwachidule:

Mawonekedwe a aluminiyamusilika gelNdi yachikasu pang'ono kapena yoyera yowonekera bwino yokhala ndi formula ya molekyulu ya mankhwala mSiO2 • nAl2O3.xH2O. Makhalidwe okhazikika a mankhwala. Osayaka, osasungunuka mu chosungunulira chilichonse kupatula maziko olimba ndi hydrofluoric acid. Poyerekeza ndi silica gel yosalala yokhala ndi porous, mphamvu ya adsorption ya chinyezi chochepa ndi yofanana (monga RH = 10%, RH = 20%), koma mphamvu ya adsorption ya chinyezi chambiri (monga RH = 80%, RH = 90%) ndi yokwera ndi 6-10% kuposa ya silica gel yosalala yokhala ndi porous, ndipo kukhazikika kwa kutentha (350℃) ndi 150 ℃ kuposa silica gel yosalala yokhala ndi porous. Chifukwa chake ndi yoyenera kugwiritsidwa ntchito ngati chosinthira kutentha kwa adsorption ndi separation agent.

Amagwiritsidwa ntchito makamaka kulekanitsa hydrocarbon yopepuka ndi mpweya wachilengedwe, kuchepetsa mame a hydrocarbon, ndikupanga mpweya wachilengedwe ndi mpweya wa gasi, pomwe mpweya wachilengedwe umaumanso. Ngati pali dontho lamadzi mu dongosolo lolekanitsa, limafunika pafupifupi 20% (chiŵerengero cha kulemera) kwa gel ya Si-Al-silica yosalowa madzi ngati gawo loteteza.

Chogulitsachi chingagwiritsidwenso ntchito ngati chogwiritsidwa ntchito wambachotsukira mano, chothandizira ndi chonyamulira chake, chingagwiritsidwenso ntchito ngati PSA, makamaka yoyenera TSA yotentha kwambiri.
