The Structural Properties OfAnamulowetsa Alumina
Aluminium yolumikizidwa imakhala ndi mawonekedwe akulu adsorption, malo akulu enieni, mphamvu yayikulu, komanso kukhazikika kwamafuta. zinthu. Ili ndi chiyanjano cholimba, ndi desiccant yopanda poizoni, yosawononga, ndipo mphamvu yake yokhazikika ndi yapamwamba. Amagwiritsidwa ntchito ngati adsorbent, desiccant, chothandizira ndi chonyamulira m'njira zambiri zomwe zimachitikira monga mafuta, feteleza wamankhwala ndi mafakitale a mankhwala.
Activated alumina ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi. Makhalidwe a aluminiyamu omwe akugwiritsidwa ntchito akufotokozedwa pansipa: Aluminium yoyendetsedwa imakhala ndi kukhazikika kwabwino ndipo ili yoyenera ngati desiccant, chotengera chothandizira, chothandizira kuchotsa fluorine, adsorbent yothamanga, kusinthika kwapadera kwa hydrogen peroxide, ndi zina zotero.
Adamulowetsa aluminiyamu ntchito ngati desiccant, makamaka ntchito mafakitale mpweya kuthamanga kuyanika zida, mpweya kuthamanga kuyanika zida ali ndi kuthamanga ntchito, zambiri m'munsimu 0.8Mpa, zomwe zimafuna adamulowetsa aluminiyamu chiŵerengero kukhala ndi mphamvu mawotchi, ngati mphamvu mawotchi ndi otsika kwambiri, n'zosavuta ufa, ufa ndi madzi osakaniza adzakhala mwachindunji kutsekereza zida payipi, choncho, An yofunika kwambiri ntchito chizindikiro cha zida zowuma mpweya activated, aluminiyamu chizindikiro cha activated mpweya wowuma. akasinja awiri, akasinja awiri ntchito alternately, kwenikweni adsorption machulukitsidwe → analytic mkombero ndondomeko, desiccant makamaka adsorption madzi, koma pansi zinthu zenizeni ntchito, mpweya kuthamanga kuyanika zida gwero mpweya adzakhala ndi mafuta, dzimbiri ndi zosafunika zina, Zinthu izi zidzakhudza mwachindunji moyo utumiki wa activated aluminiyamu adsorbent, chifukwa adamulowetsa, adsorbent adsorbent ndi porousation adsorbent adsorbent. madzi, mafuta adsorption ndi zabwino kwambiri, koma mafuta mwachindunji pulagi adamulowetsa alumina adsorption pore, kuti imfa ya makhalidwe adsorption, pali dzimbiri, dzimbiri m'madzi, Ufumuyo pamwamba adamulowetsa aluminiyamu, Apanga adamulowetsa aluminiyamu mwachindunji kutaya ntchito, kotero mu adamulowetsa aluminiyamu monga desiccant ntchito, yesetsani kupewa kukhudzana ndi mafuta adsorption, yesetsani kupewa kukhudzana ndi mafuta adsorption. moyo wa 1 ~ 3 zaka, ntchito kwenikweni adzakhala kuyanika mpweya mame mfundo kusankha m'malo adamulowetsa aluminiyamu. Kutentha kosinthika kwa alumina yoyendetsedwa ndi pakati pa 180 ~ 350 ℃. Nthawi zambiri, kutentha kwa nsanja ya alumina kumakwera mpaka 280 ℃ kwa maola 4. Aluminium activated imagwiritsidwa ntchito ngati wothandizira madzi, ndipo aluminium sulphate solution imagwiritsidwa ntchito ngati regenerator. Njira yothetsera aluminium sulphate regenerator ndi 2 ~ 3%, aluminiyamu yoyendetsedwa pambuyo pa machulukitsidwe a adsorption imayikidwa mu aluminium sulfate solution akuwukha, kutaya yankho, kusamba ndi madzi oyera 3 ~ 5 nthawi. Pambuyo pakugwiritsa ntchito nthawi yayitali, malo opangidwa ndi aluminiyamu amakhala achikasu chofiirira ndipo zotsatira za defluorination zimachepa, zomwe zimachitika chifukwa cha kutengeka kwa zonyansa. Itha kuthandizidwa ndi 3% hydrochloric acid kwa nthawi imodzi ndikusinthidwanso ndi njira yomwe ili pamwambapa.
