Ko te alumina kua kitea kia 8 te ahua, ko α- Al2O3, θ-Al2O3, γ- Al2O3, δ- Al2O3, η- Al2O3, χ- Al2O3, κ- Al2O3 me ρ- Al2O3, he rereke ano nga ahuatanga o te hanganga tonotono. Ko te Gamma activated alumina he karaihe kapi tata, he kore e rewa ki te wai, engari he wairewa ki te waikawa me te kawakore. Ko te konumohe whakahohe Gamma he ngoikore te tautoko waikawa, he rewa teitei 2050 ℃, ka taea te hanga i te konumohe i roto i te ahua hydrate ki te waikura me te porosity teitei me te mata motuhake teitei, he waahanga whakawhiti i roto i te whānuitanga o te pāmahana. I te teitei ake o te pāmahana, na te whakamaroketanga me te whakamaaramatanga, ka puta te Al2O3surface ki te ruruku hāora haunga (pokapū alkali) me te konumohe (pokapū waikawa), me te mahi catalytic. Na reira, ka taea te whakamahi i te alumina hei kawe, hei whakakorikori me te cocatalyst.Ko te konumohe whakahohe Gamma he paura, he kowhatu, he takai me etahi atu. Ka taea e matou te mahi kia rite ki to hiahia.γ-Al2O3, i kiia ko "Alumiina whakahohe", he momo marara nui marara nui, na tona hanganga pore e taea te whakarite, te rahi o te mata motuhake, te pai o te mahi adsorption, te mata me nga painga o te waikawa me te pai o te waiariki, te mata microporous me nga taonga e tika ana mo te mahi catalytic, na reira ka waiho hei kaikawe hinu me te chromatography. whai wāhi nui i roto i te hinu hydrocracking, hydrogenation whakamahine, hydrogenation reforming, dehydrogenation tauhohenga me te motoka pau te pure pure process.Gamma-Al2O3 is wide used as catalyst carrier because of the adjustability of its pore structure and surface acidity. Ka whakamahia te γ- Al2O3 hei kaikawe, haunga ka whai hua ki te marara me te whakapumau i nga waahanga kaha, ka taea hoki te whakarato i te pokapū kaha alkali waikawa, te tauhohenga synergistic me nga waahanga kaha catalytic. Ko te hanganga pore me nga ahuatanga o te mata o te whakakorikori e whakawhirinaki ana ki te kawe kawe γ-Al2O3, na reira ka kitea he kaikawe mahi teitei mo te tauhohenga catalytic motuhake ma te whakahaere i nga ahuatanga o te kawe kawe gamma alumina.Ko te Gamma activated alumina he mea hanga mai i tana pseudo-boehmite o mua mai i te 400~600 ℃ te whakamaroketanga o te pāmahana teitei, no reira ko nga ahuatanga ahupūngao o te mata ka tino whakatauhia e tona pseudo-boehmite o mua, engari he maha nga huarahi ki te hanga pseudo-boehmite, me nga puna rereke o te pseudo-boehmites3 leadsO. Heoi, ki te hunga whakakōkī ki te whakaritenga motuhake ki te kawe alumina, whakawhirinaki anake i runga i te mana o te pseudo-boehmite precursor he uaua ki te whakatutuki, me tango ki te prophase faaineineraa me te tukatuka pou whakakotahi huarahi ki te whakatika i nga āhuatanga o te alumina ki te whakatutuki i ngā whakaritenga rerekē. Ina he teitei ake te pāmahana i te 1000 ℃, ka puta te alumina i muri i te huringa o te wahanga: γ→δ→θ→α-Al2O3, kei roto i a γ、δ、θ he kohinga kati pūtoru, ko te rereketanga anake kei te tohatoha o nga katote konumohe i roto i te tetrahedral me te octahedral, no reira kaore e nui te rereketanga o enei waahanga o nga hanganga. Ko nga katote hāora i roto i te wahanga alpha he tarapi tata hexagonal, ko nga matūriki waikura konumohe he huihuinga nui, he tino heke te waahi mata.
Rokiroki:lA ape i te makuku, karohia te panuku, te maka me te tino ohorere i te wa o te kawe waka, me whakarite nga waahi ua.lMe penapena i roto i te whare putunga maroke me te hau kia kore ai e poke te makuku ranei.Mōkī:Momo

Konumina Whakahohe me te Pahakawa Permanganate
Ko te adsorption matū o ngā rawa whakamahia nuitia, hou whakakōkī hoa-taiao matatau matatau. Ko te whakamahi i te kaha oxidizing pāhare pāporo permanganate, te hau kino i roto i te hau hāora pirau i roto i te tikanga ki te whakatutuki i te kaupapa o te purenga. Ko nga hau kino ko te whanariki oxides(so2), methyl, acetaldehyde, hauota waikura, hauwai sulfide me te iti o te kukū o te aldehydes me te org acids he tino kaha ki te tango. I te nuinga o te wa ka whakamahia me te caybon kua whakahohehia hei whakapai ake i te pai o te whakauru. Ka taea hoki te whakamahi i roto i nga huawhenua me nga hua hei whakauru i te hau ethylene.
