Daim ntawv thov ntawm activated alumina li adsorbent
Jan 09, 2022
Cov kev lag luam tseem ceeb ntawm activated alumina li adsorbents muaj xws li roj ziab, kua ziab, dej purification, xaiv adsorption hauv kev lag luam roj av, thiab cov txheej txheem chromatographic sib cais.
Vim hais tias activated alumina muaj ib tug muaj zog affinity rau dej, nws yog dav siv nyob rau hauv roj kom qhuav. Cov pa roj uas tuaj yeem qhuav nrog activated alumina feem ntau suav nrog: acetylene, cracking gas, coke cub gas, hydrogen, oxygen, cua, ethane, hydrogen chloride, propane, ammonia, ethylene, hydrogen sulfide, propylene, argon, methane, sulfur dioxide, Cov pa roj carbon dioxide, cov pa roj carbon monoxide, helium, nitrogen, chlorine, thiab lwm yam. Txij li thaum ua kom muaj alumina tso tawm ntau cov cua sov thaum nws nqus dej, daim ntawv thov yuav tsum tau tsim los ntawm kev ua kom tiav, xws li lub peev xwm ziab, ziab kom qhuav, hloov hluav taws xob thiab rov tsim dua tshiab. .
Cov kua dej tseem ceeb uas tuaj yeem qhuav los ntawm kev ua kom muaj alumina yog: muaj ntxhiab hydrocarbons, polymer olefins, roj av, kerosene, cyclohexane, propylene, butene, thiab ntau halogenated hydrocarbons. Thaum cov kua no nyob rau hauv kev sib cuag nrog alumina, ob yuav tsis hnov mob los yog polymerize, thiab tib lub sij hawm, cov kua qhuav tsis muaj cov khoom uas yooj yim adsorbed ntawm alumina nto thiab tsis yooj yim tshem tawm thaum lub sij hawm regeneration.
Nyob rau hauv cov nqe lus ntawm kev lim dej, ntxiv rau kev siv tsuas yog siv los tshem tawm cov tshuaj fluoride hauv cov dej haus, activated alumina kuj zoo heev rau kev tshem tawm cov xim thiab tsw ntawm cov dej phwj tuaj. Tsis tas li ntawd, activated alumina kuj tau siv dav hauv kev rov qab los thiab kev xaiv adsorption ntawm carbohydrates thiab kev saib xyuas lub zog ntawm cov roj.
