Chidule cha aluminiyamu yoyendetsedwa
Activated alumina, yemwenso amadziwika kuti activated bauxite, amatchedwa activated alumina mu Chingerezi. Alumina omwe amagwiritsidwa ntchito muzothandizira nthawi zambiri amatchedwa "activated alumina". Ndi porous, kwambiri omwazikana olimba zinthu ndi lalikulu pamwamba. Mawonekedwe ake a microporous ali ndi mawonekedwe ofunikira pakuwongolera, monga kutsatsa, ntchito zapamtunda, kukhazikika kwamafuta, ndi zina zambiri, motero amagwiritsidwa ntchito ngati chothandizira komanso chonyamulira chotengera zochita zamankhwala.
The spherical activated alumina pressure swing oil adsorbent ndi white spherical porous particles. The aluminiyamu adamulowetsa ali yunifolomu tinthu kukula, yosalala pamwamba, mkulu mawotchi mphamvu, wamphamvu hygroscopicity, si kutupa ndi kusweka pambuyo mayamwidwe madzi, ndipo amakhalabe zosasintha. Ndiwopanda poizoni, wopanda fungo, komanso wosasungunuka m'madzi ndi ethanol.
Alumina
Sisungunuka m'madzi ndipo imatha kusungunuka pang'onopang'ono mu sulfuric acid. Itha kugwiritsidwa ntchito kuyeretsa zitsulo zotayidwa komanso ndizinthu zopangira zitsulo, zadothi, zotsukira ndi miyala yamtengo wapatali.
Alumina amagwiritsidwa ntchito ngati adsorbent, chothandizira komanso chonyamulira chothandizira amatchedwa "aluminiyamu activated". Ili ndi mawonekedwe a porosity, kubalalitsidwa kwakukulu komanso malo akuluakulu enieni. Amagwiritsidwa ntchito kwambiri pochiza madzi, petrochemical, fine chemical, biological and pharmaceutical fields.
Makhalidwe a aluminiyamu
1. Malo akuluakulu apadera: aluminiyamu yoyendetsedwa imakhala ndi malo apamwamba kwambiri. Mwa kuwongolera moyenerera dongosolo la sintering la aluminiyamu, aluminiyamu yoyendetsedwa ndi malo enaake okwera mpaka 360m2 / G ikhoza kukonzedwa. The aluminiyamu adamulowetsa wokonzeka ntchito colloidal aluminium hydroxide decomposed ndi NaAlO2 monga zopangira ali ndi pore yaing'ono kukula ndi malo enieni pamwamba 600m2 / g.
2. Maonekedwe a pore osinthika: Nthawi zambiri, zinthu zomwe zimakhala ndi pore yapakatikati zimatha kukonzedwa pophika ndi aluminiyamu ya hydroxide yoyera. Small pore mankhwala akhoza kukonzekera pokonzekera adamulowetsa aluminiyamu guluu zotayidwa, etc. pamene lalikulu pore adamulowetsa aluminiyamu akhoza kukonzekera powonjezera zinthu organic, monga ethylene glycol ndi CHIKWANGWANI, pambuyo kuyaka.
3. Pamwamba pake ndi acidic ndipo imakhala yabwino kutentha kutentha.
Ntchito ya aluminiyamu activated
Aluminiyamu adamulowetsa ali m'gulu la mankhwala aluminiyamu, amene makamaka ntchito monga adsorbent, madzi oyeretsa, chothandizira ndi chonyamulira chonyamulira. Aluminiyamu yoyendetsedwa imatha kutengera madzi mu gasi, nthunzi wamadzi ndi zakumwa zina. Kutsatsa kukadzaza, kumatha kutentha pafupifupi 175-315. D ine. Adsorption ndi reactivation akhoza kuchitidwa nthawi zambiri.
Kuwonjezera pa kugwiritsidwa ntchito ngati desiccant, imathanso kuyamwa mpweya wothira mafuta kuchokera ku mpweya woipa, hydrogen, carbon dioxide, gasi wachilengedwe, ndi zina zotero.
Itha kugwiritsidwa ntchito ngati defluorinating wothandizira pamadzi akumwa a fluorine (okhala ndi mphamvu yayikulu ya defluorinating), defluorinating wothandizira pozungulira alkanes popanga alkylbenzene, deacidifying and regenerating agent yamafuta a thiransifoma, wowumitsa mpweya mumakampani opanga mpweya. , mafakitale a nsalu ndi mafakitale apakompyuta, chowumitsa chopangira mpweya wodziwikiratu, ndi chowumitsa ndi choyeretsa mu feteleza wamankhwala, kuyanika kwa petrochemical ndi mafakitale ena.
