E 8 te iti rawa o te ahua o te alumina, ko α- Al2O3, θ-Al2O3, γ- Al2O3, δ- Al2O3, η- Al2O3, χ- Al2O3, κ- Al2O3 me ρ- Al2O3, o ratou ahuatanga hanganga tonotono. he rereke ano.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 ahua o nga rauemi totoka marara nui, na tona hanganga pore e taea te whakarite, he nui te waahanga mata motuhake, he pai te mahi adsorption, te mata me nga painga o te waikawa. me te pai o te waiariki pai, te mata microporous me nga ahuatanga o te mahi catalytic, na reira ka waiho hei whakakorikori tino whakamahia, kawe whakakōkī me te kawe chromatography i roto i te ahumahi matū me te hinu, me te whai wāhi nui i roto i te hinu hydrocracking, hydrogenation whakamahine, hydrogenation whakahou, te tauhohenga whakaheke wai me te tukanga purenga ngongo motopaika. Kei te whakamahia whanuitia a Gamma-Al2O3 hei kawe whakakorikori na te mea he pai te whakatikatika o tona hanganga pore me te waikawa o te mata.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 i mua mai i te 400 ~ 600 ℃ te whakamaroketanga o te pāmahana teitei, no reira ka whakatauhia nga ahuatanga ahupūngao o te mata e tona pseudo-boehmite o mua, engari he maha nga huarahi ki te hanga pseudo-boehmite, me nga puna rereke. o te pseudo-boehmite ka arahi ki te kanorau o te gamma – Al2O3.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.A, no te teitei ake te pāmahana i te 1000 ℃ i roto i te whakamahi, ka puta te alumina i muri i te huringa wāhanga: γ→δ→θ→α-Al2O3, i roto ia ratou γ、δ、θ he tarapēke tata pūtoru, te rerekētanga anake takoto i roto i te tohatoha o te konumohe katote i roto i tetrahedral me te octahedral, no reira karekau he rerekeetanga o nga hanganga o enei waahanga.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
