Kev siv alumina hauv catalysts feem ntau hu ua "activated alumina". Nws yog cov khoom ntxeem tau, cov khoom tawg yooj yim heev nrog thaj tsam loj, thiab nws cov microporous nto yuav tsum tau los ntawm catalysis, xws li Adsorption kev ua tau zoo, nto ua haujlwm, zoo thermal stability, thiab lwm yam. rau tshuaj tiv thaiv.
Lub spherical activated alumina li siab viav vias roj adsorbent yog dawb kheej kheej ntxeem tau hais. Activated alumina yog lub tshuab ua kom muaj txiaj ntsig zoo rau kev ziab kom qhuav ntawm cov kab dej, tsim rau cov khoom siv hluav taws xob tsis muaj cua sov.
Alumina siv los ua adsorbent, catalyst thiab catalyst cab kuj yog hu ua "activated alumina", uas muaj cov yam ntxwv ntawm porosity, siab dispersion thiab loj tshwj xeeb thaj chaw, thiab yog dav siv nyob rau hauv petrochemical, nplua tshuaj, lom thiab tshuaj thiab lwm yam teb.
