Activated Alumina Pob Ntau Lawm Technology

Nyob rau hauv txoj kev no, alumina hydroxide yog siv los ua raw khoom los ntawm crushing, ceev lub cev qhuav dej, granulation, hydration, activation roasting, tshuaj ntsuam thiab ntim, thiab lwm yam. Cov yam ntxwv tseem ceeb yog raws li nram no: nyob rau hauv lub saum toj no ceev lub cev qhuav dej txheej txheem, inlet kub. ntawm lub qhov cub ci ci yog 850-950 degree, thiab qhov hluav taws xob kub tswj ntawm 430-490 degree . Cov txheej txheem ntawm cov binder siv nyob rau hauv cov txheej txheem granulation yog 100 qhov chaw ntawm dej, 8-12 qhov chaw ntawm ammonium bicarbonate, 6-10 qhov chaw ntawm sodium carbonate, 40-60 qhov chaw ntawm ρ alumina, nyob rau hauv lub hydration txheej txheem ntawm cov khoom siv pob, cov khoom siv pob hydration kho tom qab chav dej, qhov kub yog 90-100 degree, lub sij hawm 4-6 teev, cov txheej txheem roasting, qhov kub thiab txias yog 390-430 degree, Roasting lub sij hawm 30-40 feeb. Lub pob activated alumina uas ua los ntawm cov txheej txheem ntawm kev tsim khoom muaj qhov tshwj xeeb ntawm 280m # ntxiv rau [2] / g saum toj no, uas yog siv dav hauv kev lag luam petrochemical, tshwj xeeb tshaj yog hauv kev ua kom huv ntawm ethylene, butene thiab lwm yam tshuaj raw khoom adsorption. Cov nyhuv purification yog qhov zoo heev, thiab tuaj yeem tiv thaiv cov tshuaj tiv thaiv isomerization ntawm butene monomer.
