Alumina firfircoon, oo ah adsorbent wax ku ool ah, ayaa leh codsiyo badan oo kala duwan oo ka saarista TBC (p-tert-butylcatechol) ee styrene.
1.Mabda'a xayeysiinta:
1) Porosity: alumina fir fircoon waxay leedahay qaab dhismeed dalool ah kaas oo bixisa aag weyn oo dusha sare ah oo si wax ku ool ah u xajin kara TBC-ga styrene.
2) hygroscopicity sare: hygroscopicity sare ee alumina firfircoon ayaa awood u siinaya in ay ku dhejiso biyaha iyo walxaha kale ee dabiiciga ah, taas oo gacan ka geysaneysa hagaajinta waxtarka xayeysiiska.
2. Saamaynta adsorption
1) Daraasadaha tijaabada ah: daraasaduhu waxay muujiyeen in alumina firfircooni ay si fiican u qabato xayeysiinta TBC ee styrene. Qiyaastii 3 saacadood ee daawaynta quusitaanka ka dib, waxa ku jira TBC aad ayaa loo dhimay; ka dib qiyaastii 12 saacadood oo daawaynta immersion ah, waxa ku jira TBC waa la dhimay ilaa heer aan saamaynaynin heerka beddelka polymerization.
(2) Waxqabadka Polymerization: Maaddada cis-1,4 ee qaab-dhismeedka styrene ka dib daaweynta adsorption asal ahaan lama saameeyo inta lagu jiro polymerization, laakiin qaybinta cufka kelli waa la ballaarin doonaa.
3. Codsi gaar ah:
Wax soo saarka Styrene: alumina firfircoon ayaa loo isticmaalaa sidii adsorbent ee wax soo saarka iyo nadiifinta styrene si looga saaro TBC si loo hagaajiyo tayada alaabta iyo xasilloonida.
Ilaalinta kicinta: Alumina firfircoon waxa kale oo loo istcimaali karaa kataliyad qaade si looga ilaaliyo kicinta wasakhda sida TBC oo ay u dheeraato nolosha adeeg ee kicinta.
Dhawaan, macmiilkayaga VIP wuxuu naga soo iibiyay 16 tan oo aluminium firfircoon ah si aan TBC uga saarno styrene, sawirada soo socda ayaa adiga kuu ah:
