Nyob rau hauv lub ntiaj teb kev hloov pauv ntawm kev lag luam mus rau kev ntsuab, muaj nqis siab, thiab kev txawj ntse, cov pob zeb aluminosilicate ntuj, ua tau zoo siab tau tshwm sim ua qhov txuas tseem ceeb txuas kev kho ib puag ncig nrog kev siv lag luam siab. Zeolite, ib qho pob zeb crystalline nrog cov qauv porous peb-seem tshwj xeeb, tab tom hloov pauv los ntawm cov khoom siv adsorbent kev lag luam ib txwm mus rau cov khoom siv ua haujlwm tseem ceeb hauv kev ntes cov pa roj carbon, kev kho dej, kev ua liaj ua teb niaj hnub, thiab kev ua haujlwm petrochemical, txhaj tshuaj muaj zog rau hauv kev txhim kho zoo ntawm kev lag luam. Lub npe hu ua "molecular sieve of nature," cov pob zeb no tsis yog pob zeb volcanic ib txwm muaj; nws yog cov khoom ntawm kev sib koom ua ke ntawm cov tshuaj siv lead ua ntuj thiab kev tshawb fawb niaj hnub, qhia txog qhov tseem ceeb tsis muaj qhov hloov pauv hauv kev ntxuav ib puag ncig, kev siv cov peev txheej rov ua dua tshiab, thiab kev siv hluav taws xob zoo.

Lub khawv koob tseem ceeb ntawm zeolite yog nyob rau hauv nws cov qauv "honeycomb" microporous thiab muaj peev xwm pauv ion zoo heev. Ua los ntawm cov clinoptilolite lossis mordenite uas muaj kev ntshiab siab, nws lub moj khaum tsim kom muaj thaj chaw sab hauv dav dav nrog cov qhov loj me sib xws. Tom qab kev ua kom lub cev thiab kev hloov kho tshuaj (xws li kev ua kom sov, kev hloov kho acid-base, lossis kev thauj khoom ion), nws qhia txog kev nqus dej zoo dua, kev sib xyaw molecular, thiab kev ua haujlwm catalytic - zeolite ntuj tuaj yeem "ntes" ammonia nitrogen, cov hlau hnyav, thiab cov organic compounds volatile (VOCs) hauv nws cov cages molecular, thaum tseem muaj kev ruaj khov thermal zoo heev thiab kev tiv thaiv acid. Tsim los ntawm kev siv cov pob zeb hauv av los ntawm kev sib xyaw ua ke, kev txheeb xyuas ntse, thiab cov txheej txheem hloov kho ntsuab, lub voj voog tsim khoom tswj kev siv hluav taws xob tsawg. Nrog rau kev nrov npe ntawm cov kab ke xoom-kua dej (ZLD) hauv cov nroj tsuag ua tiav, kev lag luam sib haum xeeb zoo nrog lub hom phiaj "dual carbon". Los ntawm cov pob zeb nyoos mus rau cov sieves ua haujlwm, zeolite yog cov khoom siv ruaj khov uas txo cov kev siv tshuaj rau cov lag luam downstream, ua rau nws yog lub hauv paus ntawm kev lag luam ntsuab.

Ntxiv rau nws cov txiaj ntsig tseem ceeb ntawm kev sib xyaw molecular sieving, zeolite muab cov kev daws teeb meem rau ntau yam lag luam nrog nws cov peev xwm siv tau tag nrho. Hauv kev tiv thaiv ib puag ncig, ua cov khoom siv lim dej zoo thiab cov tshuaj kho av, nws siv dav hauv kev kho dej khib nyiab hauv nroog, kev tswj cov khib nyiab radioactive, thiab kev tswj hwm smog (NOx txo qis), nrog rau kev thov nce ntxiv hauv kev lag luam ncig. Hauv txoj kev ua liaj ua teb, nws ua haujlwm ua "lub thawv khaws khoom noj khoom haus" rau av, txhim kho kev khaws dej thiab kev ua haujlwm ntawm chiv, thaum ua haujlwm ua cov khoom noj khoom haus zoo tshaj plaws los txhim kho kev noj qab haus huv ntawm tsiaj. Hauv cov khoom siv roj av thiab lub zog, zeolite catalysts yog qhov tseem ceeb rau kev tawg catalytic kua (FCC) thiab tam sim no tab tom tshawb nrhiav rau kev khaws cia hydrogen thiab cov thev naus laus zis carbon capture thiab khaws cia (CCS) zoo. Hauv kev lag luam kev tsim kho, nws yog siv ua cov khoom siv pozzolanic ua haujlwm siab rau cov pob zeb sib xyaw ua ke, muaj zog siab, pab txhawb rau cov ntawv pov thawj tsev ntsuab. Nws qhov kev hloov pauv ua tus tswj dej noo thiab tus nqus tsw kuj nthuav nws txoj kev ncav cuag mus rau hauv kev saib xyuas hauv tsev thiab cov khoom siv rau cov neeg siv khoom, ua haujlwm ua lub hauv paus tseem ceeb thoob ntiaj teb.

Tam sim no, kev lag luam zeolite tab tom nkag mus rau lub sijhawm kub ntawm kev tsim kho tshiab thiab kev nthuav dav ntawm kev lag luam. Kev ua tiav hauv kev tswj qhov loj me ntawm qhov pore, kev ua haujlwm ntawm qhov chaw, thiab cov khoom siv sib xyaw ua ke tau hloov cov khoom los ntawm cov khoom sib xyaw ua ke qis mus rau cov khoom siv molecular sieves siab, ua tau raws li qhov xav tau ntawm kev tsim tshuaj lom neeg thiab kev tsim cov pa oxygen kho mob. Kev siv tshuab ua haujlwm tau txhim kho mus rau kev txawj ntse; cov thev naus laus zis xws li hyperspectral mineral sorting thiab automated thermal activation tau ua tiav qhov huv ntawm cov mineral ntau dua 92%, tswj qhov sib txawv ntawm lub peev xwm pauv pauv hauv 2.0%, thiab txo qis kev siv hluav taws xob tag nrho los ntawm 20%. Raws li lub tebchaws loj hauv cov peev txheej zeolite (nrog cov peev txheej pov thawj tseem ceeb hauv Hebei, Inner Mongolia, thiab Zhejiang), Tuam Tshoj tau tsim ib txoj saw hlau kev lag luam tiav los ntawm kev khawb av thiab kev ua tiav mus rau kev siv lag luam kawg, nrog rau kev ua haujlwm siab thiab hloov kho cov zeolites ntuj ua kom nrawm hloov mus rau kev xa khoom muaj nqis siab.

Vim muaj ob txoj kev hloov pauv thoob ntiaj teb ntawm kev txhim kho ntsuab thiab kev txhim kho kev lag luam, qhov tseem ceeb ntawm zeolite tau dhau los ua qhov tseem ceeb. Nws sib haum xeeb zoo nrog lub hom phiaj kev txhim kho ntawm kev tswj kev ua qias tuaj, kev ua liaj ua teb kom ruaj khov, thiab kev tsim tshuaj lom neeg zoo, muab kev txhawb nqa rau kev nce qib ntawm cov lag luam ntsuab tshiab. Kev lag luam zeolite thoob ntiaj teb loj hlob mus txog ntau dua 5.2 billion Asmeskas las hauv xyoo 2025, thiab kev lag luam Suav teb tshaj 7.5 billion yuan; kwv yees tias qhov loj me ntawm kev lag luam rau cov khoom siv ua haujlwm zeolite zoo yuav ncav cuag 75 billion yuan los ntawm xyoo 2030. Los ntawm "lub tshuab lim dej" kev lag luam mus rau "lub cav catalytic" thiab "tus saib xyuas kev ua liaj ua teb," zeolite tab tom tawg cov ciam teb ntawm daim ntawv thov, ua pov thawj tias cov zaub mov yooj yim tuaj yeem ua tus thawj coj hauv kev tsim kho tshiab ntsuab. Nws tsis yog cov tshauv volcanic niche ntxiv lawm, tab sis yog cov khoom siv tseem ceeb rau kev tsim kom muaj lub kaw lus lag luam niaj hnub ntsuab, ntse, thiab muaj nqis siab, tsav tsheb kev lag luam thoob ntiaj teb mus rau yav tom ntej ruaj khov thiab lim dej.
