ʻAlumina i hoʻāla ʻia

ʻO ka alumina i hoʻāla ʻia (ʻo ke ʻano molekala Al2O(3-x)(OH)2x,0 < x < 0.8) kekahi o nā huahana kemika inorganic i hoʻohana nui ʻia ma ka honua. Ma muli o kona ʻano porous, ka ʻili kikoʻī kiʻekiʻe a me ke kūlana hoʻololi paʻa ʻole, ʻoi aku ka nui o ka hana o ka alumina i hoʻāla ʻia. Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻoulu a me ka mea lawe mea hoʻoulu i ka ʻoihana petrochemical a me ka ʻoihana mea hoʻoulu. Loaʻa i ka alumina i hoʻāla ʻia nā ʻano adsorption, no laila hoʻohana ʻia ia ma ke ʻano he desiccant no ke kinoea a me ka wai, adsorbent no ka hoʻomaʻemaʻe kinoea, mea hoʻoheheʻe no ka wai inu, mea hoʻopau kala a me ke ʻala no ka wai ʻauʻau ʻoihana, a pēlā aku. I kēia manawa, ʻo nā huahana alumina i hoʻāla ʻia e ka dehydration wikiwiki. Pili ka alumina i hoʻāla ʻia i ka alumina calcined i wili piha ʻia a haku ʻia me (20%-90%) alpha-al2o3 me ka nui o ke aniani mua o 1 micron. Formula: Al2O3, Kaumaha Molecular: 101.96.

Hoʻohana nui ʻia ka alumina i hoʻāla ʻia i ka petrochemical, ka hoʻomaʻemaʻe ʻaila, nā mea uila, ethylene, propylene, ea a me nā mea hoʻomaloʻo ʻē aʻe, ua hoʻohana ʻia i nā mea kanu hydrogen peroxide he nui, nā mea kanu mea hoʻouluulu, nā mea kanu oxygen a me nā ʻāpana hoʻomaʻemaʻe petrochemical, a ua loaʻa nā hopena maikaʻi. ʻO ka pōpō alumina i hoʻāla ʻia e like me ka polarity o adsorbent e hoʻoholo i ka ikaika o ka wai, oxide, acetic acid, alkali a me nā pilina ikaika ʻē aʻe, he desiccant hohonu hohonu, adsorption o nā molekala polar adsorbent. Hiki ke hoʻohana nui ʻia i ka hoʻomaloʻo hohonu o ke kinoea haki petroleum, ethylene propylene gas, hana hydrogen, mea hoʻokaʻawale ea, mīkini hoʻomaloʻo ea mea kani, mālama fluoride i loko o ka hydrogen peroxide, hiki nō hoʻi ke wehe i ke kinoea sulfur hydrogen, carbon dioxide, hydrogen fluoride, hydrocarbons a me nā mea haumia ʻē aʻe i loko o ke kinoea neoneo, kūpono loa no ka wai fluorine.

ʻO ka alumina hana he keʻokeʻo a he hua poepoe liʻiliʻi paha o ka ʻulaʻula liʻiliʻi, he nui ka stoma huluhulu a me ka hana kiʻekiʻe, maikaʻi ka hopena wai fluorine kiʻekiʻe, maʻalahi ka hana hou ʻana, ʻaʻohe nui o ka hoʻopilikia, koe wale nō ka poʻe e hoʻohana ana i ka wai inu ma waho aʻe o ka hana fluorine, hiki nō ke hoʻohana ʻia ma ke ʻano he adsorbent, desiccant a me ka mea lawe catalyst. Hoʻohana nui ʻia ia i ka ʻenekinia wai piula, ka ʻenekinia hoʻomaʻemaʻe wai, ka mea kanu hydrogen peroxide, ka mea kanu mea hoʻouluulu, ka mea kanu oxygen a me ka ʻoihana petrochemical. Loaʻa i ka alumina i hoʻāla ʻia nā waiwai adsorption, ka hana catalytic o ka porous, ka hoʻolaha kiʻekiʻe, kahi kikoʻī nui o ka alumina, kūpono no nā ʻano maloʻo kinoea a me ka wai, hiki ke hoʻohana ʻia no ka wai inu a me nā lako ʻoihana deoxidization, defluorination, dearsenization, sewer decolorization, deodorization a pēlā aku. Hana ʻia kēia huahana me ka alumina maʻemaʻe kiʻekiʻe ma o ka hoʻomākaukau ʻepekema a me ka hoʻopau catalytic. Hoʻohana ʻia ia ma ke ʻano he adsorbent, desiccant, catalyst a me ka mea lawe i nā kaʻina hana he nui e like me ka petroleum, chemical fertilizer a me ka ʻoihana kemika. Wahi a kāna USES hiki ke hoʻokaʻawale ʻia i: alumina i hoʻāla ʻia adsorbent, desiccant a me ka mea lawe catalyst.

Hana ʻia ka alumina i hoʻāla ʻia me ka alumina maʻemaʻe kiʻekiʻe ma o ka hoʻomākaukau ʻepekema a me ka hoʻopau catalytic. ʻO nā ʻāpana porous poepoe keʻokeʻo, like ka nui o ka ʻāpana, ʻili laumania, ikaika mechanical, hygroscopicity ikaika, ma hope o ka omo ʻana o ka wai ʻaʻole e hoʻonui a ʻaʻole e haki i nā huahana mua, ʻaʻohe mea ʻawahia, ʻono ʻole, ʻala ʻole, hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik. He adsorbent molekala me ka ʻili kikoʻī nui. Ke haʻahaʻa ka waiwai PH a me ka alkalinity o ka wai maka, ʻoi aku ka kiʻekiʻe o ka hiki ke wehe i ka fluorine ma mua o 3.0mg/g. Hiki ke hoʻohana ʻia i ka wai inu a me nā lako hana ʻoihana defluorination, dearsenic, sewer decolorization, deodorization, etc. ʻO nā huahana nui: ka mea hoʻohemo alumina fluoride i hoʻāla ʻia, ka mea hoʻoheheʻe alumina i hoʻāla ʻia, ka mea hoʻoulu alumina i hoʻāla ʻia, ka mea hoʻoulu alumina i hoʻāla ʻia, ka alumina i hoʻāla ʻia i hoʻāla ʻia i ka hydrogen peroxide.

ʻO ka alumina desiccant i hoʻāla ʻia: ʻo kēia huahana he ʻano microporous a me ka spherical mea, me ka hana adsorption ikaika, kahi ʻili kikoʻī nui, paʻakikī compressive kiʻekiʻe, ola lawelawe lōʻihi, a hiki ke hoʻohana pinepine ʻia e ke ʻano hana hou. He keʻokeʻo kēia huahana, mea porous spherical ʻaʻohe ʻawaʻawa, ʻaʻohe ʻala, ʻaʻohe pauka, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai. Hoʻohana nui ʻia ia i ka ʻoihana petrochemical, ʻoihana kemika, ʻoihana lole, ʻoihana gula a me nā ʻoihana ʻē aʻe, e like me ka hoʻomaloʻo makani mea kani, ka mea hoʻokaʻawale ea adsorption swing pressure, hiki i ka dew point adsorption ke piʻi aʻe ma mua o -41 degere, hiki ke hoʻohana ʻia no ke kila, ka ʻaila petroleum cracking gas, ethylene, propylene i ka pae wai a me ka maloʻo hohonu o ka pae kinoea.
