Nyob rau hauv lub loj heev ntawm tshuaj lom neeg kev lag luam thiab cov ntaub ntawv txuj ci,molecular siieves, raws li cov khoom siv tau zoo, ua si pivotal lub luag haujlwm. Ntawm lawv, Zeolite molecular sieves tau dhau los ua cov ntaub ntawv tseem ceeb hauv kev sib cais, purification thiab catration crystal qauv thiab adsorption zoo nkauj. Peb yuav tshawb cov ntawv thov ntawm 13x Apg, 4a, 5a, thiab 3a molecular sieves hauv kev kho dej thiab adsorption sib cais.
13x molecular sab cib thiab zeeolite molecular sieves
13X molecular sab cib yog ib tug tswv cuab ntawm lub Zeolite molecular sab cib tsev, paub rau nws qhov loj me me thaj chaw, loj pore loj thiab zoo heev dej adsorpt muaj peev xwm. Nws yog dav siv nyob rau hauv kev ziab thiab ua kom huv si ntawm gases thiab kua, tshwj xeeb tshaj yog nyob rau hauv cov roj av ua kom zoo nkauj, thiab nqus pa. Lub cev pob txha ntawm Zeolite molecular sieves yog muaj los ntawm cov ntsiab lus xws li silicon, uas tuaj yeem xaiv cov kab mob microcous li cas, yog li ua tiav kev sib cais.
Molecular sab cib lub cev qhuav dej thiab apg molecular sab cib
Hauv daim ntawv thov kev txhaj tshuaj tivthaiv, molecular sieves, tshwj xeeb tshaj yog 13x apg molecular sides (apg sawv cev rau ib tug txheej txheem ntau lawm lossis txhim kho kev ua tau zoo. Lawv tuaj yeem tshem tawm cov dej noo los ntawm roj lossis kua thiab ua kom cov khoom qhuav, uas yog qhov tseem ceeb rau kev siv tshuaj lom neeg thiab chaw cia khoom. Cov lus qhia ntawm APG thev naus laus zis tuaj yeem ua ntau ntxiv txhim kho qhov ruaj khov thiab kev pabcuam lub neej ntawm cov molecular sides.
Molecular sab cib yam thiab cov ntawv thov
4a molecular sab cib: feem ntau yog siv nyob rau hauv cov cua kom qhuav, hydrocarbon sib cais thiab qee yam catalytic cov kev txiav txim siab, nws lub xeem txiav txim siab hom molecules uas tuaj yeem adsorbed.
5a molecular sieve: zoo tshaj yog tsim nyog rau kev rho cov pa roj carbon dioxide los ntawm huab cua thiab rau lub cev qhuav dej hauv cov txheej txheem ntawm cov txheej txheem hydrocarbon.
3A molecular sieve: feem ntau yog siv rau kom qhuav me me me molecular qhov hnyav roj xws li hydrogen, helium, thiab lwm yam.
Molecular sieve adsorbents thiab desiccants: nyob rau hauv cov teb khoom noj ntim, ua pov thawj ntawm cov khoom siv hluav taws xob, thiab lwm yam, cov tshuaj tua hluav taws xob tau siv cov txee hluav taws xob ua kom zoo rau lub txee txee ntawm cov khoom lag luam.
