Dej Caw Dej hauv Distillation Ntauwd / Desiccant / Adsorbent / Hollow iav molecular sieve

Lus piav qhia luv luv:

Molecular sieve 3A, tseem hu ua molecular sieve KA, nrog rau qhov aperture ntawm li 3 angstroms, tuaj yeem siv rau ziab cov pa roj thiab cov kua dej nrog rau lub cev qhuav dej ntawm hydrocarbons. Nws kuj tseem siv dav rau kev ziab kom tiav ntawm cov roj av, cov pa tawg, ethylene, propylene thiab cov pa roj carbon monoxide.

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

Product Detail

Khoom cim npe

Zeolite molecular sieves muaj cov qauv siv lead ua tsis tu ncua, txhua tus uas muaj cov qauv pore ntawm qee qhov loj thiab cov duab, thiab muaj thaj tsam loj. Feem ntau zeolite molecular sieves muaj zog acids nyob rau saum npoo, thiab muaj ib tug muaj zog Coulomb teb nyob rau hauv crystal pores rau polarization. Cov yam ntxwv no ua rau nws ua tau zoo heev catalyst. Heterogeneous catalytic cov tshuaj tiv thaiv yog nqa tawm ntawm cov khoom catalysts, thiab cov kev ua catalytic muaj feem xyuam rau qhov loj ntawm cov crystal pores ntawm cov catalyst. Thaum lub zeolite molecular sieve yog siv los ua catalyst lossis catalyst carrier, kev nce qib ntawm cov tshuaj tiv thaiv catalytic yog tswj los ntawm qhov pore loj ntawm zeolite molecular sieve. Qhov loj thiab cov duab ntawm crystal pores thiab pores tuaj yeem ua lub luag haujlwm xaiv hauv cov tshuaj tiv thaiv catalytic. Nyob rau hauv cov kev mob tshwm sim dav dav, zeolite molecular sieves ua lub luag haujlwm tseem ceeb hauv cov kev taw qhia cov tshuaj tiv thaiv thiab nthuav tawm cov duab-xaiv kev ua haujlwm catalytic. Qhov kev ua tau zoo no ua rau zeolite molecular sieves cov khoom siv catalytic tshiab nrog lub zog muaj zog.
