Cawv Dehydration nyob rau hauv Distillation Tower / Desiccant / Adsorbent / Hollow iav molecular sieve Featured Duab

Kev Qhuav Dej Cawv Hauv Distillation Tower / Desiccant / Adsorbent / Hollow iav molecular sieve

Kev Piav Qhia Luv:

Lub tshuab molecular sieve 3A, tseem hu ua molecular sieve KA, nrog lub qhov loj li 3 angstroms, siv tau rau kev ziab cov roj thiab cov kua dej nrog rau kev ziab cov hydrocarbons. Nws kuj siv dav rau kev ziab tag nrho cov roj av, cov roj tawg, ethylene, propylene thiab cov roj ntuj.

Lub hauv paus ntsiab lus ua haujlwm ntawm cov molecular sieves feem ntau yog cuam tshuam nrog qhov loj ntawm cov molecular sieves, uas yog 0.3nm / 0.4nm / 0.5nm feem. Lawv tuaj yeem nqus cov roj molecules uas muaj cov molecular diameter me dua li qhov loj ntawm qhov loj. Qhov loj dua ntawm qhov loj ntawm qhov loj, qhov loj dua qhov muaj peev xwm nqus tau. Qhov loj ntawm qhov loj sib txawv, thiab cov khoom uas tau lim thiab sib cais kuj sib txawv. Hauv cov lus yooj yim, 3a molecular sieve tsuas yog tuaj yeem nqus cov molecules hauv qab 0.3nm, 4a molecular sieve, cov molecules adsorbed kuj yuav tsum tsawg dua 0.4nm, thiab 5a molecular sieve zoo ib yam. Thaum siv ua desiccant, molecular sieve tuaj yeem nqus tau txog li 22% ntawm nws qhov hnyav hauv cov dej noo.

Cov Lus Qhia Txog Khoom

Cov Cim Npe Khoom

Cov zeolite molecular sieves muaj cov qauv siv lead ua ib txwm muaj, txhua tus muaj cov qauv pore ntawm qee qhov loj me thiab cov duab, thiab muaj thaj chaw loj. Feem ntau cov zeolite molecular sieves muaj cov kua qaub muaj zog nyob rau ntawm qhov chaw, thiab muaj lub zog Coulomb teb hauv cov qhov siv lead ua rau polarization. Cov yam ntxwv no ua rau nws yog ib qho catalyst zoo heev. Cov tshuaj tiv thaiv heterogeneous catalytic yog ua tiav ntawm cov catalysts khov kho, thiab cov haujlwm catalytic yog cuam tshuam nrog qhov loj me ntawm cov qhov siv lead ua ntawm cov catalyst. Thaum lub zeolite molecular sieve siv ua catalyst lossis cov catalyst carrier, kev nce qib ntawm cov tshuaj tiv thaiv catalytic yog tswj los ntawm qhov loj me ntawm lub zeolite molecular sieve. Qhov loj me thiab cov duab ntawm cov qhov siv lead ua thiab cov qhov siv lead ua tuaj yeem ua lub luag haujlwm xaiv hauv cov tshuaj tiv thaiv catalytic. Nyob rau hauv cov xwm txheej dav dav, zeolite molecular sieves ua lub luag haujlwm tseem ceeb hauv kev coj ua tshuaj tiv thaiv thiab ua kom pom cov duab-xaiv catalytic kev ua tau zoo. Qhov kev ua tau zoo no ua rau zeolite molecular sieves yog cov khoom siv catalytic tshiab nrog lub zog muaj zog.
