Incamake ya alumina ikora
Alumina ikora, izwi kandi nka bauxite ikora, yitwa alumina ikora mucyongereza. Alumina ikoreshwa muri catalizator ikunze kwitwa "alumina ikora". Nibintu byoroshye, bikwirakwijwe cyane hamwe nubuso bunini. Ubuso bwa microporome ifite ibimenyetso biranga catalizike, nkibikorwa bya adsorption, ibikorwa byubuso, ituze ryiza ryumuriro, nibindi, bityo rero ikoreshwa cyane nka catalizator na catalizike itwara imiti.
Umuyoboro ukoreshwa wa alumina umuvuduko wa swing amavuta adsorbent ni umweru wera uduce duto duto. Alumina ikora ifite ubunini buke, ubuso bworoshye, imbaraga za mashini nyinshi, hygroscopique ikomeye, ntabwo yabyimba kandi ikavunika nyuma yo gufata amazi, kandi ntigihinduka. Ntabwo ari uburozi, impumuro nziza, kandi ntishobora gushonga mumazi na Ethanol.
Alumina
Ntishobora gushonga mumazi kandi irashobora gushonga gahoro gahoro acide sulfurike. Irashobora gukoreshwa mugutunganya aluminiyumu yicyuma kandi nigikoresho cyibanze cyo gukora umusaraba, farufari, ibikoresho bivunika hamwe namabuye y'agaciro.
Alumina ikoreshwa nka adsorbent, catalizator na catalizator yitwa "alumina ikora". Ifite ibiranga porosity, gutatana cyane hamwe nubuso bunini bwihariye. Ikoreshwa cyane mugutunganya amazi, peteroli-chimique, imiti myiza, ibinyabuzima na farumasi.
Ibiranga alumina
1. Ubuso bunini bwihariye: alumina ikora ifite ubuso bwihariye bwihariye. Mugucunga neza sisitemu yo gucumura ya alumina, alumina ikora hamwe nubuso bwihariye bugera kuri 360m2 / G irashobora gutegurwa. Alumina ikora yateguwe ukoresheje hydroxide ya aluminium ya colloidal yangirika na NaAlO2 nkibikoresho fatizo bifite ubunini buke bwa pore nubuso bwihariye bugera kuri 600m2 / g.
2. Imiterere yubunini bwa pore: Muri rusange, ibicuruzwa bifite ubunini buciriritse birashobora gutegurwa muguteka hamwe na hydroxide ya aluminium nziza. Ibicuruzwa bito binini birashobora gutegurwa mugutegura alumina ikora hamwe na aluminiyumu, nibindi mugihe ubunini bunini bwa pore ikora alumina irashobora gutegurwa wongeyeho ibintu bimwe na bimwe kama, nka Ethylene glycol na fibre, nyuma yo gutwikwa.
3. Ubuso ni acide kandi bufite ubushyuhe bwiza.
Imikorere ya alumina ikora
Alumina ikora ni iy'icyiciro cya alumina ya chimique, ikoreshwa cyane nka adsorbent, isukura amazi, catalizator hamwe na cataliste. Alumina ikora ifite ubushobozi bwo guhitamo adsorb amazi muri gaze, umwuka wamazi hamwe namazi amwe. Iyo adsorption imaze guhaga, irashobora gushyuha nka 175-315. D egree. Adsorption na reactivation birashobora gukorwa inshuro nyinshi.
Usibye gukoreshwa nka desiccant, irashobora kandi gukuramo amavuta yo gusiga amavuta ava muri ogisijeni yanduye, hydrogène, dioxyde de carbone, gaze naturel, nibindi. Kandi irashobora gukoreshwa nkinkunga ya catalizator na catalizator kandi nkinkunga yo gusesengura chromatografique.
Irashobora gukoreshwa nka agent ya defluorinating kumazi yo kunywa ya fluor nyinshi (ifite ubushobozi bunini bwa defluorinating), agent ya defluorinating yo kuzenguruka alkane mu musaruro wa alkylbenzene, umukozi wangiza kandi usubirana amavuta ya transformateur, ibikoresho byuma bya gaze munganda zikora ogisijeni. , inganda zimyenda ninganda za elegitoronike, ibikoresho byuma byumuyaga wibikoresho byikora, hamwe nuwumisha hamwe nisuku mu ifumbire mvaruganda, gukama peteroli nizindi nganda.
