Molecular sieves yog cov ntaub ntawv nrog pores los yog raws ntawm qhov loj me me, cov pores no tuaj yeem nqus cov molecules me dua li nws txoj kab uas hla mus rau sab hauv ntawm cov kab noj hniav, thiab muaj qhov zoo tshaj plaws adsorption muaj peev xwm rau polar molecules thiab unsaturated molecules, yog li nws muaj peev xwm cais cov molecules nrog ntau degrees. ntawm polarity, sib txawv degrees ntawm saturation, sib txawv molecular ntau thiab tsawg thiab txawv boiling ntsiab lus, uas yog, nws muaj lub luag hauj lwm ntawm "kev soj ntsuam" molecules. Yog li hu ua molecular sieve.
1.Rau Gas cais:Molecular sieves tuaj yeem siv los cais cov roj sib txawv raws li lawv qhov ntau thiab tsawg thiab cov khoom. Piv txwv li, nyob rau hauv kev sib cais ntawm natural gas, molecular sieves yuav adsorb impurities xws li dej vapor thiab carbon dioxide, kom ntseeg tau lub purity ntawm cov natural gas.
2.In Petroleum Kev Lag Luam:Molecular sieves siv tau los tshem tawm cov dej thiab lwm yam impurities los ntawm cov roj crude, txhim kho qhov zoo ntawm cov khoom kawg. Tsis tas li ntawd, molecular sieves tau ua haujlwm hauv cov txheej txheem catalytic txhawm rau txhim kho cov txiaj ntsig ntawm cov khoom tsim nyog. Hauv kev tsim cov roj av thiab lwm yam roj, lawv pab sib cais sib txawv hydrocarbon feem raws li lawv qhov ntau thiab tsawg molecular. Qhov no tsis tsuas yog txhim kho kev ua haujlwm ntawm cov txheej txheem tsim khoom, tab sis kuj ua rau kev tsim cov roj huv nrog cov ntsiab lus ntawm cov sulfur qis.
