Petrochemicals, Tshuaj sib cais, thiab roj sib cais. Ib qho ntawm feem ntau siv cov molecular siic sides yog xh-7, paub rau nws cov adsorption zoo tshaj plaws thiab kev siab ua kom ruaj khov.

XH-7 molecular sievesyog cov khoom siv hluavtaws uas muaj ib qho peb-seem network ntawm cov xhab thiab tawb. Cov channel no muaj cov khoom sib txawv, tso cai xwb molecules ntawm qhov loj me uas dhau mus. Cov cuab yeej no ua rau XH-7 Qhov kev xaiv zoo rau kev xaiv cov ntawv thov, qhov twg nws tuaj yeem tshem tawm cov tsis muaj kev cuam tshuam los ntawm kev sib xyaw.

Lub siab thermal ruaj khov ntawm XH-7 yog lwm qhov tseem ceeb ntxiv, tso cai rau nws los tiv thaiv ntau yam tsis tau poob nws cov adsorption thaj chaw. Cov cuab yeej no ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau cua sov, xws li tshem dej ntawm cov kuab tshuaj los ntawm cov kuab tshuaj.

Ib qho ntawm feem ntau siv ntawm xh-7 molecular sieves yog nyob rau hauv lub turification ntawm nkev ntawm cov nkev. XH-7 tuaj yeem tshem cov impurities xws li dej, leej faj tebchaw, thiab carbon dioxide, uas ua rau muaj ntau dua cov roj purity nkev roj. Qhov no, nyeg, ua rau kom txhim kho kev sib txuas ua ke ua haujlwm thiab txo cov pa tawm.

Hauv kev lag luam kws tshuaj, XH-7 yog siv los ua kom huv cov tshuaj sib txuas thiab tshem tawm impurities. Nws cov ris tsho zoo li lub ntsej muag loj tso cai rau kev xaiv adsorption, kom ntseeg tau tias tsuas yog qhov xav tau Molecule thiaj li ntes tau. Qhov no ua rau muaj cov tshuaj muaj zog tshaj nrog cov kev mob tshwm sim tsawg dua.

XH-7 molecular sievesKuj tseem siv rau hauv kev tsim cov pa oxygen, qhov chaw uas lawv xaiv adsorb nitrogen los ntawm huab cua, ua rau muaj cov pa siab ntau dua ntawm cov pa oxygen. Qhov no muaj txiaj ntsig zoo hauv kev siv tshuaj kho mob uas yuav tsum muaj cov pa oxygen.

Hauv cov ntsiab lus, XH-7 molecular sieves yog ib qho tseem ceeb hauv ntau yam kev lag luam, muaj kev ruaj khov zoo nkauj, thiab niaj hnub pore loj. Los ntawm cov pa roj ua kom huv si rau cov tshuaj purification, xh-7 plays lub luag haujlwm tseem ceeb hauv kev ua kom muaj cov khoom purity thiab efficiency.

Thaum nws los xaiv txoj cai molecular sieve rau ib daim ntawv thov ua haujlwm tshwj xeeb, nws yog qhov tseem ceeb uas yuav tsum tau adsorbed, kev ua haujlwm ntawm kev ua haujlwm, thiab theem yuav tsum muaj kev coj dawb huv.

XH-7 molecular sievesMuaj lub pore loj ntawm kwv yees li ntawm 10 angstroms, ua rau lawv haum rau kev siv cov lwg me me uas yuav tsum tau sib cais. Lawv kuj muaj thaj chaw siab, uas tso cai rau ntau dua ntawm cov chaw adsorption, ua rau muaj kev txhim kho kev ua tau zoo.

Lwm qhov zoo dua ntawm XH-7 molecular siieves yog lawv cov tshuaj muaj peev xwm ruaj khov. Lawv tuaj yeem tiv taus ntau qhov tseem ceeb ntawm PT qhov tseem ceeb thiab tiv taus cov kua qaub, hauv paus, thiab cov kuab tshuaj, ua rau lawv haum rau kev siv cov chaw hnyav.

Txhawm rau kom ntseeg tau qhov kev ua tau zoo ntawm XH-7 molecular sieves, nws yog qhov tseem ceeb kom ua raws li cov ntawv qhia cov txheej txheem rau kev ua haujlwm thiab tsim dua tshiab. Kev ua kom muaj zog cuam tshuam cov dej noo tam sim no hauv cov siieve, thaum lub sij hawm renaleration cuam tshuam cov adsorbed molecules thiab rov qab cov sieves 'Adsorption cov khoom.

Hauv kev xaus, xh-7 molecular sieve muaj ntau yam zoo dua lwm cov adsorbents, ua rau lawv xaiv tau xaiv nrov hauv ntau qhov kev lag luam. Lawv cov khaub ncaws muaj zog loj heev, siab thermal stability, thiab adsorption zoo nkauj ua rau lawv zoo tagnrho rau kev xaiv kev sib cais cov ntawv thov. Los ntawm xaiv txoj cai molecular sieve rau ib daim ntawv thov tshwj xeeb thiab ua raws li cov khw cov txheej txheem rau kev ua kom muaj thiab cov neeg siv khoom siv, cov neeg siv tuaj yeem ua kom pom kev ua tau zoo thiab ua tau zoo.
