- Ua kapa ʻia ʻo Aluminum oxide e like me desiccant, adsorbent, catalyst a me catalyst carrier "Activated alumina", nona ka porous, kiʻekiʻe dispersion a me ka hōʻiliʻili nui ʻana, a hoʻohana nui ʻia i nā kula o ka petrochemical, kemika maikaʻi, ke ola a me ka lāʻau lapaʻau.
- Hana ʻia ka alumina i hana ʻia e ka alumini hydroxide hoʻomehana a me ka dehydration.ʻO ka alumini hydroxide ka mea i ʻike ʻia he hydrated alumini oxide, a ʻo kona ʻano kemika ʻo Al2O3· nH2O, ʻokoʻa ka nui o ka wai crystalline i loko.Ma hope o ka wela a me ka maloʻo o ka alumini hydroxide, hiki ke loaʻa iāρ-Al2O3.

- ʻO ka alumina hoʻoikaika ʻia no ka ʻāpana o ka alumina kemika, hoʻohana nui ʻia no ka desiccant, adsorbent, wai hoʻomaʻemaʻe wai, catalyst a me ka mea lawe catalyst.Loaʻa i ka alumina i hoʻāla ʻia ka adsorption koho o nā kinoea, nā wai wai a me kekahi mau wai.Hiki ke ho'ōla hou ʻia ka saturation adsorption ma ka hoʻomehana ʻana a me ka wehe ʻana i ka wai ma kahi o 175 ~ 315 ℃.Hiki ke hana i ka nui adsorption a me ka desorption.
- Ma waho aʻe o ka lawelawe ʻana ma ke ʻano he desiccant, hiki ke hoʻopaʻa ʻia nā lubricant vapors mai ka oxygen i hoʻohaumia ʻia, hydrogen, carbon dioxide, kūlohelohe a pēlā aku.Hiki ke hoʻohana 'ia e like me catalyst a me catalyst lawe a me ka waihoʻoluʻu papa kālailai lawe.Hiki ke hoʻohana ʻia e like me ka wai inu fluorine kiʻekiʻe (nui ka nui o ka fluorine), defluoride o ka alkane e holo ana i ka hana alkylbenzene, deacid regenerating agent o ka ʻaila transformer, hoʻomaloʻo kinoea i ka ʻoihana oxygen, ʻoihana textile, ʻoihana uila, makani mea kani, mea hoʻomaloʻo i ke kemika. mea hoʻomomona, hoʻomaloʻo petrochemical, mea hoʻomaʻemaʻe (kahi hau a hiki i-40 ℃), a me ke kaomi hoʻololi adsorption dew point a hiki i-55 ℃ i ka ʻoihana hoʻokaʻawale ea.He desiccant maikaʻi loa ia me ka hoʻomaloʻo hohonu o ka wai.He kūpono loa no nā ʻāpana hana hou ʻole wela.
