Kuj tseem muaj lub npe hu ua cov dej huv niaj hnub qhib alumina, Lus Askiv lub npe hu ua Activated Alumina lossis Reactive alumina; rov alumin (I) um oxide. Kev siv cov alumina (AL 2 O 3 ) hauv cov catalyst, feem ntau hu ua activated alumina, yog qhov ntxeem tau, cov khoom tawg yooj yim uas muaj qhov chaw loj thiab thaj chaw microporous nrog cov khoom uas xav tau rau catalysis. Xws li adsorption kev ua tau zoo, fluorine tshem tawm kev ua haujlwm, kev ua kom qhuav, ua haujlwm sab saum npoo, zoo tshaj plaws thermal stability, thiab lwm yam, nws yog dav siv los ua lub hauv paus rau tsev neeg desiccant thiab tshuaj lom neeg cov tshuaj tiv thaiv thiab cov cab kuj muaj.
