Ua ʻike ʻia ʻo Alumina ma ka liʻiliʻi he 8 mau ʻano, ʻo ia hoʻi ʻo α-Al2O3, θ-Al2O3, γ-Al2O3, δ-Al2O3, η-Al2O3, χ-Al2O3, κ-Al2O3 a me ρ-Al2O3, ʻokoʻa hoʻi ko lākou mau ʻano macroscopic. ʻO ka alumina i hoʻāla ʻia he kristal cubic kokoke, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i ka waikawa a me ka alkali. He kākoʻo waikawa nāwaliwali ka alumina i hoʻāla ʻia e Gamma, he kiʻekiʻe kona wahi hoʻoheheʻe he 2050 ℃, hiki ke hana ʻia ka gel alumina i loko o ka oxide me ka porosity kiʻekiʻe a me ka ʻili kikoʻī kiʻekiʻe, loaʻa iā ia nā pae hoʻololi i kahi ākea ākea. I ke kiʻekiʻe o ka mahana, ma muli o ka dehydration a me ka dehydroxylation, ʻike ʻia ka ʻili Al2O3 i ka hoʻohuihui ʻana o ka oxygen unsaturated (kikowaena alkali) a me ka alumini (kikowaena waikawa), me ka hana catalytic. No laila, hiki ke hoʻohana ʻia ka alumina ma ke ʻano he mea lawe, catalyst a me cocatalyst.Hiki i ka alumina i hoʻāla ʻia e Gamma ke pauka, granules, strips a i ʻole nā mea ʻē aʻe. Hiki iā mākou ke hana e like me kāu koi. ʻO γ-Al2O3, i kapa ʻia ʻo "alumina i hoʻāla ʻia", he ʻano mea paʻa porous kiʻekiʻe, ma muli o kona ʻano pore hiki ke hoʻololi ʻia, kahi ʻili kikoʻī nui, hana adsorption maikaʻi, ʻili me nā pono o ka acidity a me ke kūpaʻa thermal maikaʻi, ʻili microporous me nā waiwai e pono ai o ka hana catalytic, no laila lilo ia i mea hoʻonui nui ʻia, mea lawe catalyst a me ka mea lawe chromatography i ka ʻoihana kemika a me ka ʻaila, a he kuleana koʻikoʻi i ka hydrocracking aila, hydrogenation refining, hydrogenation reforming, dehydrogenation reaction a me ke kaʻina hana hoʻomaʻemaʻe ʻana i ka ʻōpala kaʻa. Hoʻohana nui ʻia ʻo Gamma-Al2O3 ma ke ʻano he mea lawe catalyst ma muli o ka hiki ke hoʻololi ʻia o kona ʻano pore a me ka acidity o ka ʻili. Ke hoʻohana ʻia ʻo γ-Al2O3 ma ke ʻano he mea lawe, ʻoiai hiki ke loaʻa nā hopena e hoʻopuehu a hoʻopaʻa i nā ʻāpana hana, hiki nō hoʻi ke hāʻawi i ke kikowaena hana alkali acid, ka hopena synergistic me nā ʻāpana hana catalytic. ʻO ke ʻano o ka pore a me nā waiwai o ka ʻili o ka mea hoʻoulu e pili ana i ka mea lawe γ-Al2O3, no laila e loaʻa kahi mea lawe hana kiʻekiʻe no ka hopena catalytic kikoʻī ma o ka kaohi ʻana i nā waiwai o ka mea lawe gamma alumina.ʻO ka alumina i hoʻāla ʻia e Gamma ka mea maʻamau i hana ʻia mai kona pseudo-boehmite mua ma o ka dehydration wela kiʻekiʻe 400 ~ 600 ℃, no laila ua hoʻoholo nui ʻia nā waiwai physicochemical o ka ʻili e kona pseudo-boehmite mua, akā he nui nā ala e hana ai i ka pseudo-boehmite, a ʻo nā kumu like ʻole o ka pseudo-boehmite e alakaʻi i ka ʻokoʻa o ka gamma - Al2O3. Eia nō naʻe, i kēlā mau mea hoʻoulu me nā koi kūikawā i ka mea lawe alumina, hilinaʻi wale i ka kaohi o ka pseudo-boehmite mua he paʻakikī ke hoʻokō, pono e lawe ʻia i ka hoʻomākaukau prophase a me ka hoʻopili ʻana i nā ʻano hana e hoʻoponopono i nā waiwai o alumina e hoʻokō i nā koi like ʻole. Ke kiʻekiʻe ka mahana ma mua o 1000 ℃ i ka hoʻohana ʻana, hana ʻia ka alumina ma hope o ka hoʻololi ʻana o ka pae: γ→δ→θ→α-Al2O3, i waena o lākou he γ、δ、θ he cubic close packing, ʻo ka ʻokoʻa wale nō ma ka hoʻolaha ʻana o nā ion alumini i loko o ka tetrahedral a me ka octahedral, no laila ʻaʻole nui ka loli o nā ʻano o kēia hoʻololi ʻana o ka pae. Hoʻopili kokoke nā iona oxygen i ka pae alpha i nā ʻāpana hexagonal, hui hou nā ʻāpana alumini oxide, a ua emi nui ka ʻili kikoʻī.
Ka Waihona:E pale i ka makū, e pale i ka ʻōwili ʻana, ka hoʻolei ʻana a me ka hoʻopūhoihoi ʻoi i ka wā e lawe ʻia ana, pono e hoʻomākaukau ʻia nā pono pale ua.Pono e mālama ʻia i loko o kahi hale kūʻai maloʻo a me ka ea e pale ai i ka haumia a i ʻole ka makū.Pūʻolo:ʻAno
