Daim ntawv thov ntawm alumina ua haujlwm

Cov teb thov ntawm activated alumina yog feem ntau yog adsorption teb thiab catalyst teb.

1. daim ntawv thov ntawm alumina ua haujlwm hauv thaj chaw adsorption

Ua ib qho adsorbent, nws yog ib qho ntawm cov kev siv tseem ceeb ntawm activated alumina, uas yog vim nws qhov chaw loj tshwj xeeb, cov qauv pore tsim nyog, cov khoom zoo, kev ruaj khov tshuaj zoo thiab ntau lwm yam zoo. Nws cov ntawv thov kev lag luam tseem ceeb suav nrog cov roj qhuav, cov kua qhuav, kev ntxuav thiab kho dej, thiab kev xaiv adsorption hauv kev lag luam roj av.

2 daim ntawv thov ntawm alumina ua haujlwm hauv roj ziab

Vim tias alumina ua kom sov thiab dej muaj zog heev, nws muaj zog heev hauv qhov muaj peev xwm ziab ntawm cov dej hauv cov roj, hauv kev siv kev lag luam ntawm cov desiccant, calcium chloride, silica gel, calcium oxide ziab muaj peev xwm qis dua li alumina ua kom sov, tsuas yog barium oxide ziab muaj peev xwm siab dua li alumina ua kom sov me ntsis. Tib lub sijhawm, vim tias cov tshuaj lom neeg ruaj khov ntawm alumina zoo, tsuas yog ib feem me me ntawm cov roj thiab nws muaj cov tshuaj tiv thaiv, yog li nws tuaj yeem ziab ntau hom roj, cov ntaub ntawv tau qhia tias nws tuaj yeem ziab acetylene, hydrogen, oxygen, cua, nitrogen thiab lwm yam ntau dua 20 hom roj.

3. daim ntawv thov ntawm alumina ua haujlwm hauv cov kua qhuav

Kev ziab kua yog qhov nyuaj dua li kev ziab roj, thiab qhov xav tau desiccant yog qhov siab heev. Ua ntej, cov tshuaj tiv thaiv tsis tuaj yeem tshwm sim ntawm cov khoom ntawm cov kua lossis ntawm cov kua thiab cov pa oxygen thaum cov kua sib cuag nrog cov adsorbent. Tam sim no, nws tau ua pov thawj tias cov kua uas tuaj yeem ziab los ntawm alumina yog cov hydrocarbons aromatic, macromolecular alkenes, roj av, kerosene, thiab lwm yam.

4. daim ntawv thov ntawm alumina ua haujlwm hauv thaj chaw catalyst

Hauv ntau cov txheej txheem catalytic kev lag luam, tsis yog nws tus kheej siv ua catalyst xwb, alumina kuj siv dav ua tus nqa khoom ntawm cov khoom siv catalyst, thiab, nrog kev txhim kho txoj kev tsim cov catalyst carrier alumina, ntau txoj kev siv hauv kev lag luam catalyst carrier, xws li txoj kev thaiv, txoj kev granulating, compaction, txoj kev nias rau hauv lub pob thiab lwm yam, yog li ntawd, nws tuaj yeem ua ntau yam duab catalyst carrier.
