The Structural Properties OfAlumina yoyendetsedwa
Aluminium activated ili ndi mawonekedwe a kutsatsa kwakukulu, malo akulu apadera, 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. Zomwe zimagwira ntchito za aluminiyamu zikufotokozedwa pansipa: Aluminium yoyendetsedwa imakhala ndi kukhazikika kwabwino ndipo ili yoyenera ngati desiccant, chotengera chothandizira, chochotsa fulorini, chopondereza cha adsorbent, chotsitsimutsa chapadera cha hydrogen peroxide, ndi zina zotero. monga chothandizira ndi chothandizira chonyamulira.
Adamulowetsa aluminiyamu ntchito ngati desiccant, makamaka ntchito mafakitale mpweya kuthamanga kuyanika zida, mpweya kuthamanga kuyanika zida ali ndi kukakamiza ntchito, zambiri m'munsimu 0.8Mpa, amene amafuna adamulowetsa aluminiyamu chiŵerengero kuti ndi wabwino makina mphamvu, ngati makina mphamvu kwambiri. otsika, n'zosavuta ufa, ufa ndi madzi kuphatikiza mwachindunji kutsekereza payipi zipangizo, kotero, chizindikiro chofunika adamulowetsa aluminiyamu ntchito ngati desiccant ndi mphamvu, air pressure kuyanika zipangizo, zambiri akasinja awiri, akasinja awiri ntchito mosinthasintha, kwenikweni. adsorption saturation → analytic cycle process, desiccant makamaka adsorption madzi, koma pansi pa zochitika zenizeni zogwirira ntchito, mpweya wowumitsa zipangizo zowumitsa mpweya udzakhala ndi mafuta, dzimbiri ndi zonyansa zina, Izi zidzakhudza mwachindunji moyo wautumiki wa alumina adsorbent, chifukwa adamulowetsa. alumina ndi porous adsorption zakuthupi, masoka adsorption polarity madzi, mafuta adsorption ndi zabwino kwambiri, koma mafuta mwachindunji adamulowetsa alumina adsorption pore, kuti imfa ya makhalidwe adsorption, pali dzimbiri, dzimbiri m'madzi, Ufumuyo pamwamba adamulowetsa aluminiyamu, Adzamulowetsa adamulowetsa mwachindunji kutaya ntchito, kotero adamulowetsa alumina monga ntchito desiccant, yesetsani kupewa kukhudzana ndi mafuta, dzimbiri, adamulowetsa alumina adsorbent monga desiccant ambiri ntchito moyo wa zaka 1 ~ 3, ntchito yeniyeni adzakhala youma mpweya. mame amaloza kusankha ngati angalowe m'malo mwa 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.
