Cov Khoom Siv Hauv TsevAlumina ua kom nquag

Alumina ua kom muaj zog muaj cov yam ntxwv ntawm kev nqus tau loj, thaj chaw tshwj xeeb loj, lub zog siab, thiab kev ruaj khov zoo thermal. Nws muaj kev sib raug zoo, yog cov tshuaj desiccant tsis muaj tshuaj lom, tsis muaj corrosive, thiab nws lub peev xwm zoo li qub. Nws yog siv los ua adsorbent, desiccant, catalyst thiab carrier hauv ntau cov txheej txheem tshuaj xws li roj av, tshuaj chiv thiab kev lag luam tshuaj lom neeg.

Alumina ua kom nquag yog ib qho ntawm cov khoom siv tshuaj inorganic uas siv ntau tshaj plaws hauv ntiaj teb. Cov yam ntxwv ntawm alumina ua kom nquag tau piav qhia hauv qab no: Alumina ua kom nquag muaj kev ruaj khov zoo thiab tsim nyog ua desiccant, tus neeg nqa khoom catalyst, tus neeg sawv cev tshem tawm fluorine, tus neeg nqus dej siab, tus neeg sawv cev rov ua dua tshiab tshwj xeeb rau hydrogen peroxide, thiab lwm yam. Alumina ua kom nquag siv dav ua catalyst thiab catalyst carrier.

Alumina ua haujlwm siv ua desiccant, feem ntau siv rau hauv cov khoom siv cua txias, cov khoom siv cua txias muaj lub zog ua haujlwm, feem ntau qis dua 0.8Mpa, uas xav tau qhov piv ntawm alumina ua haujlwm kom muaj lub zog zoo, yog tias lub zog ua haujlwm qis dhau, nws yooj yim rau hmoov, hmoov thiab dej ua ke yuav ncaj qha thaiv cov kav dej khoom siv, yog li, Ib qho cim tseem ceeb ntawm alumina ua haujlwm siv ua desiccant yog lub zog, cov khoom siv cua txias, feem ntau ob lub tank, ob lub tank ua haujlwm hloov pauv, qhov tseeb yog qhov adsorption saturation → txheej txheem analytic cycle, desiccant feem ntau yog adsorption dej, tab sis nyob rau hauv cov xwm txheej ua haujlwm tiag tiag, cov khoom siv cua txias yuav muaj roj, xeb thiab lwm yam tsis huv, Cov yam no yuav ncaj qha cuam tshuam rau lub neej ua haujlwm ntawm alumina ua haujlwm adsorbent, vim tias alumina ua haujlwm yog cov khoom siv adsorption porous, ntuj adsorption polarity ntawm dej, roj adsorption kuj zoo heev, tab sis roj yuav ncaj qha ntsaws lub qhov adsorption alumina ua haujlwm, yog li ntawd qhov poob ntawm cov yam ntxwv adsorption, muaj xeb, xeb hauv dej, txuas rau ntawm qhov chaw ntawm alumina ua haujlwm, Yuav ua rau alumina ua haujlwm ncaj qha poob kev ua haujlwm, yog li hauv alumina ua haujlwm siv desiccant, sim tsis txhob sib cuag nrog Cov roj, xeb, cov khoom siv alumina ua kom lub cev nqus tau ua desiccant feem ntau siv tau 1 ~ 3 xyoos, qhov siv tiag tiag yuav yog kom qhuav cov roj dew point kom txiav txim siab seb puas yuav hloov cov alumina ua kom lub cev nqus tau. Qhov kub rov ua dua ntawm cov alumina ua kom lub cev nqus tau yog ntawm 180 ~ 350 ℃. Feem ntau, qhov kub ntawm cov alumina ua kom lub cev nqus tau nce mus txog 280 ℃ rau 4 teev. Cov alumina ua kom lub cev nqus tau siv ua tus neeg sawv cev kho dej, thiab cov kua txhuas sulfate siv ua tus neeg tsim kho dua tshiab. Cov kua ntawm cov kua txhuas sulfate rov ua dua tshiab yog 2 ~ 3%, cov alumina ua kom lub cev nqus tau tom qab nqus tau muab tso rau hauv cov kua txhuas sulfate, pov tseg cov kua, ntxuav nrog dej huv 3 ~ 5 zaug. Tom qab siv ntev, qhov chaw ua kom lub cev nqus tau yog xim av daj thiab cov nyhuv defluorination txo qis, uas yog los ntawm kev nqus cov khoom tsis huv. Nws tuaj yeem kho nrog 3% hydrochloric acid rau 1 zaug thiab tom qab ntawd rov ua dua tshiab los ntawm txoj kev saum toj no.
