Thaum peb siv activated alumina txhawb nqa, nws muaj qhov kub thiab txias tsis kam thiab oxidation tsis kam, uas yuav pab tau rau qee yam ntawm peb txoj haujlwm. Txawm li cas los xij, nws qhov kev ua tau zoo yuav cuam tshuam los ntawm cov ntsiab lus saum npoo, uas ua rau txo qis hauv nws txoj kev siv.
1. Tag nrho cov alumina txhawb nyob rau hauv lub xeev hloov pauv muaj dej ntau los yog tsawg, thiab muaj ib co hydroxyl pawg thiab raug txhuas atoms nyob rau saum npoo, yog li qhia cov yam ntxwv ntawm B acid thiab L acid, uas muaj feem xyuam rau cov kev ua tau zoo ntawm cov khoom. kev them nyiaj yug alumina.
2. Cov acidity saum npoo yog cuam tshuam nrog kev npaj ntawm cov khoom, tshwj xeeb tshaj yog cov impurity ions thiab kev kho cua sov.
3. Lwm qhov xwm txheej yog tias qhov tsis zoo ions xws li halogen yuav txhim kho cov av acidity ntawm activated alumina, thiab kev txhim kho ntawm acidity yuav txhawb cov catalytic nyhuv ntawm alumina nws tus kheej ntawm hydrocarbon cracking thiab isomerization.
Nws tuaj yeem pom los ntawm cov lus qhia saum toj no tias cov yam ntxwv cuam tshuam rau kev ua haujlwm ntawm lub tshuab nqus tsev alumina muaj feem cuam tshuam rau cov khoom xws li dej thiab kub, yog li nws yuav tsum tau them sai sai rau cov ntsiab lus dej hauv cov txheej txheem tsim khoom thiab kev npaj, thiab tseem them nyiaj. saib xyuas cov ntsiab lus saum toj no.
