Activated alumina, raws li qhov ua tau zoo adsorbent, muaj ntau yam kev siv hauv kev tshem tawm TBC (p-tert-butylcatechol) los ntawm styrene.
1.Adsorption txoj cai:
1) Porosity: activated alumina muaj cov qauv ntxeem tau uas muab thaj chaw loj thiab tuaj yeem nqus tau TBC los ntawm styrene.
2) High hygroscopicity: siab hygroscopicity ntawm activated alumina enables nws mus adsorb ob dej thiab lwm yam organic teeb meem, uas yuav pab txhim kho cov adsorption efficiency.
2. Cov nyhuv adsorption
1) Cov kev tshawb fawb soj ntsuam: cov kev tshawb fawb tau pom tias activated alumina ua tau zoo nyob rau hauv adsorption ntawm TBC los ntawm styrene. Tom qab kwv yees li 3 teev ntawm kev kho mob immersion, cov ntsiab lus ntawm TBC tau txo qis; Tom qab li ntawm 12 teev ntawm kev kho mob immersion, cov ntsiab lus ntawm TBC tau raug txo mus rau ib theem uas tsis cuam tshuam rau polymerization hloov pauv tus nqi.
(2) Polymerization kev ua tau zoo: Cov ntsiab lus ntawm cis-1,4 qauv ntawm styrene tom qab kev kho adsorption yog qhov pib tsis muaj kev cuam tshuam thaum lub sij hawm polymerization, tab sis cov molecular loj faib yuav nthuav dav.
3.Kev thov tshwj xeeb:
Styrene ntau lawm: activated alumina yog siv los ua ib qho adsorbent hauv kev tsim thiab ua kom huv ntawm styrene kom tshem tawm TBC los ntawm nws txhawm rau txhim kho cov khoom zoo thiab ruaj khov.
Kev tiv thaiv catalyst: Activated alumina kuj tseem siv tau los ua cov catalyst cab kuj los tiv thaiv cov catalyst los ntawm impurities xws li TBC thiab ua kom lub neej ua haujlwm ntev ntawm catalyst.
Tsis ntev los no, peb cov neeg siv khoom VIP tau yuav 16 tons ntawm activated alumina los ntawm peb kom tshem tawm TBC los ntawm styrene, cov duab hauv qab no yog rau koj siv:
