Kev tsim cov ntaub ntawv tseem ceeb rau activated alumina
Oct 27, 2021
Muaj ob yam khoom siv raw rau kev tsim cov khoom siv alumina, ib qho yog" ceev depowder" ua los ntawm gibbsite los yog Bayerite, thiab lwm yam yog pseudo-boehmite ua los ntawm aluminate los yog txhuas ntsev los yog ob qho tib si. .
Kev tsim khoom ntawm x-ρ alumina
X-ρ alumina yog cov khoom siv tseem ceeb rau kev tsim cov khoom siv alumina. Abbreviated li FCA txawv teb chaws, nws yog hu ua" ceev depowder" nyob rau hauv Suav teb vim nws yog alumina hmoov ua los ntawm lub cev qhuav dej sai." Ceev cov hmoov tshem tawm" yog kev sib xyaw ntawm x-alumina thiab ρ-alumina, thiab cov ntsiab lus sib txawv vim qhov sib txawv ntawm cov khoom siv.
Txoj kev tsim khoom ntawm pseudo-boehmite
Ntuj los yog khoom tsim tawm alumina monohydrate thiab trihydrate alumina tsis tuaj yeem siv los ua desiccants, adsorbents, catalysts thiab catalyst carriers vim lawv qhov chaw tshwj xeeb tsawg, qhov pore ntim me me, thiab kev ua haujlwm tsawg. Alumina monohydrate los yog alumina trihydrate yuav tsum tau ua tiav rau hauv pseudo-boehmite. Pseudo-boehmite muaj qhov tshwj xeeb ntawm qhov chaw, qhov pore loj, qhov pore loj, thiab kev ua haujlwm siab. Nws yog tsim rau siv raws li desiccant, adsorbent thiab catalyst thiab catalyst carrier nyob rau hauv kev lag luam petrochemical, chiv thiab tso pa roj.
