Alumina yakawanikwa kuti iripo muchimiro che8, i α-Al2O3, θ-Al2O3, γ-Al2O3, δ-Al2O3, η-Al2O3, χ-Al2O3, κ-Al2O3 uye ρ-Al2O3, hunhu hwayo hwemacroscopic hwakasiyanawo. Gamma activated alumina ikristaro yakakomberedzwa ne cubic, isinganyungudike mumvura, asi inonyungudika mu acid ne alkali. Gamma activated alumina itsigiro isina simba ye acid, ine nzvimbo yekunyungudika yakakwira 2050 ℃, alumina gel muchimiro che hydrate inogona kugadzirwa kuita oxide ine porosity yakakwira uye pamusoro chaiwo, ine zvikamu zvekuchinja munzvimbo yakakura yekupisa. Pakupisa kwakanyanya, nekuda kwekushaya mvura uye dehydroxylation, Al2O3surface inoita se coordination unsaturated oxygen (alkali centre) uye aluminium (acid centre), ine catalytic activity. Nokudaro, alumina inogona kushandiswa se carrier, catalyst uye cocatalyst.Gamma activated alumina inogona kunge iri upfu, granules, strips kana zvimwe. Tinogona kuita sezvinodiwa nemi. γ-Al2O3, yainzi "activated alumina", imhando yezvinhu zvakasimba zvinopararira zvine porous, nekuda kwechimiro chayo chinogadziriswa chepore, nzvimbo yakakura chaiyo, kushanda zvakanaka kwe adsorption, pamusoro une mabhenefiti e acidity uye kugadzikana kwakanaka kwekupisa, pamusoro pe microporous ine hunhu hunodiwa hwe catalytic action, saka inova catalyst inoshandiswa zvakanyanya, catalyst carrier uye chromatography carrier muindasitiri yemakemikari nemafuta, uye inoita basa rakakosha mu hydrocracking yemafuta, hydrogenation refine, hydrogenation reforming, dehydrogenation reaction uye automobile exhaust cleansing process. Gamma-Al2O3 inoshandiswa zvakanyanya se catalyst carrier nekuda kwekugadzirisa kwechimiro chepore uye surface acidity. Kana γ-Al2O3 ikashandiswa se catalyst, inogonawo kuparadzanisa uye kudzikamisa zvikamu zvinoshanda, inogonawo kupa acid alkali active centre, synergistic reaction ne catalytic active components. Maumbirwo emaburi uye hunhu hwepamusoro hwe catalyst zvinoenderana ne catalyst yeγ-Al2O3, saka catalyst inoshanda zvakanyanya inowanikwa kuti iite catalytic reaction chaiyo nekudzora hunhu hwe catalyst ye gamma alumina.Alumina inoshandiswa neGamma inowanzogadzirwa ne pseudo-boehmite yayo inotangira kuburikidza ne 400~600℃ high tembiricha yemvura, saka hunhu hwe physicochemical hwepamusoro hunonyanya kutsanangurwa ne pseudo-boehmite yayo inotangira, asi kune nzira dzakawanda dzekugadzira pseudo-boehmite, uye masosi akasiyana e pseudo-boehmite anotungamira mukusiyana kwe gamma - Al2O3. Zvisinei, kune izvo zvinokonzeresa zvine zvinodiwa zvakakosha kune alumina carrier, zvinongovimba chete nekudzora kwe precursor pseudo-boehmite zvakaoma kuwana, zvinofanirwa kuendeswa ku prophase preparation uye post processing kubatanidza nzira dzekugadzirisa hunhu hwe alumina kuti husvike kune zvinodiwa zvakasiyana. Kana tembiricha yakakwira kupfuura 1000 ℃ iri kushandiswa, alumina inoitika mushure mekuchinja kwe phase: γ→δ→θ→α-Al2O3, pakati payo γ、δ、θ zviri cubic close packing, musiyano uripo chete mukugoverwa kwemaion ealuminium mu tetrahedral ne octahedral, saka kuchinja kwe phase uku hakukonzeri shanduko yakawanda yezvivakwa. Maion eokisijeni ari muchikamu chealpha akabatana nehexagonal, zvidimbu zvealuminium oxide zvinosangana zvakanyanya, nzvimbo chaiyo yekumusoro yakaderera zvakanyanya.
Kuchengetera:Dzivisa hunyoro, dzivisa kukwesha, kukanda uye kuvhundutsa panguva yekufambisa, nzvimbo dzisinganayi mvura dzinofanira kunge dzakagadzirwa.Inofanira kuchengetwa mudura rakaoma uye rine mhepo inofefetera kudzivirira kusvibiswa kana hunyoro.Pasuru:Rudzi
