Vim tias nws cov qauv pore tshwj xeeb, qhov loj ntawm thaj chaw tshwj xeeb thiab kev ua haujlwm, activated alumina pob muaj ntau yam khoom sib txawv ntawm lwm yam khoom. Nws yog feem ntau siv los ua adsorbent, desiccant thiab catalyst cab kuj rau kev ua kom huv ntawm ntau yam gases thiab kua. Nws qhov kev ua tau zoo tshaj plaws yog raws li hauv qab no:
1. High tshwj xeeb thaj chaw, 300-350m2 / g
2. So hauv dej tsis muaj softening, tawg, nthuav thiab pulverization
3. Yooj yim rau rov tsim dua thiab siv, nrog lub neej kev pab ntau tshaj 3 xyoos
4. Tus nqi hnav qis heev, Tsawg dua lossis sib npaug rau 0.1 feem pua
5. Muaj peev xwm adsorption muaj zog, ziab muaj peev xwm thiab purification muaj peev xwm
