Activated alumina, sechinhu chakawanda chinoshanda, yakaratidza kukosha kwayo kwakasiyana uye kushandiswa muminda yakawanda.Yayo porous chimiro, yakakwira nzvimbo uye kugadzikana kwemakemikari inoita kuti alumina yakagadziriswa iite basa rakakosha mu catalysis, adsorption, zvigadzirwa zvemagetsi uye zvichingodaro, zvichiita mupiro wakakosha mukufambira mberi kwemaindasitiri.
Activated alumina, inozivikanwawo sealumina, chinhu chinoumbwa nealuminium oxide.Iyo porous chimiro inopa yakagadziriswa alumina nzvimbo yakakura yepasi, ichiita kuti ive yakanakisa adsorption zvimiro uye inosimudzira chiitiko.Nekuda kwenzvimbo dzayo dzakawanda dzinoshanda nzvimbo, activated alumina inoshandiswa zvakanyanya mu catalysis.Semuenzaniso, mu petrochemical process senge catalytic cracking uye catalytic hydrogenation, activated alumina inowanzoshandiswa se catalyst carrier, iyo inogona kuvandudza maitiro ekuita uye kusarudza chigadzirwa.
Uye zvakare, activated alumina inoitawo basa rakakosha mukuchengetedzwa kwezvakatipoteredza uye kurapwa kwetsvina.Nekuda kweiyo adsorption zvivakwa, yakabatidzwa alumina inogona kushandiswa kubvisa zvinhu zvinokuvadza senge heavy metal ion uye organic zvinosvibisa kubva mumvura.Haikwanise kungovandudza kunaka kwemvura, asi zvakare kuderedza kukanganiswa kwezvakatipoteredza, zvichibatsira kuvaka nzvimbo yakachena yezvakatipoteredza.
Nekudaro, kugadzirira uye kushandiswa kweyakagadziriswa alumina inotarisanawo nemamwe matambudziko.Semuenzaniso, maitiro ayo ekugadzirira anogona kusanganisira kushandiswa kwesimba uye kukanganisa kwezvakatipoteredza, uye nzira dzekugadzira dziri nani dzinofanirwa kutsvakwa.Uye zvakare, munzvimbo dzakasiyana dzekushandisa, zvivakwa zvezvinhu uye zvimiro zvinodiwa zveakamisikidzwa alumina zvinogona kusiyana, zvinoda dhizaini yetsika uye optimization.
Muchidimbu, yakagadziriswa alumina, sechinhu chakawanda chinoshanda, inopa rutsigiro rwakakosha kune akati wandei minda.Mune ramangwana, nekuenderera mberi kwekusimudzira kwesainzi yemidziyo, zvinotendwa kuti yakabatidzwa alumina inoratidza kugona kwayo uye kukosha mune mamwe minda.
