Tshem tawm cov dej thiab sulfide xws li h2s thiab thiols
Natural Gas Lub Cev Qhuav
Lub xub ntiag yuav muaj ntau txhim kho cov nyom taw tes ntawm cov pa roj ntuj, ua roj tsis muaj zog hauv liquefection, xa xov tooj lossis sib cais nqus dej sib sib cais; kuj tseem ua cov hydrocarbon hydrate mus rau precipate thiab block cov khoom siv thiab xa hluav taws xob; Nws yog qhov yooj yim rau kev ua nrog H2S thiab CO2 nyob rau hauv cov nkev thiab mob siab corrode pipeline khoom. Sib sib zog nqus lub cev qhuav thiab ziab ntawm cov pa roj ntuj nrog cov hlab ntsha molecular yog qhov siv ntau tshaj plaws thiab cov qauv paub tab.
H2S thiab CO2 nyob rau hauv cov pa roj ntuj yuav ua nrog dej thiab mob corrode pipode loj. Acid ntuj nrog cov ntsiab lus tshaj cov qauv hauv tebchaws yuav tsum tau siv ib txwm siv los ntawm kev huv thiab desulfurization. Molecular sab cib tau tau siv dav hauv kev tshem tawm cov impurities xws li H2S, CO2 hauv cov roj.

Dej-Qhuav
Nyob rau hauv concentant siab, thaum dej cawv-dej sib tov ncav cuag ntawm qhov kev pom zoo, tsis muaj cawv nrog txoj kev distillation.
Txhawm rau ntxiv tsim cov dej cawv ntau heev, tau txais cov khoom siv tsis muaj zog, Piv nrog cov tsoos ternary azerotropic distillation txujcation, nrog lub cev qhuav dej zoo, cov khoom lag luam siab zoo, kev siv thev naus laus zis heev.
Ethanol lub cev qhuav dej molecular si cib adsorption cov qauv yog cov txheej txheem rau nqus dej ntawm kev pub ethanol. Siv cov molecular sab cib ntawm JZ-Zac, cov dej lwg me me yog 3A, thiab 2.8A, ethanol molecule yog 4.4a. Vim tias ethanol molecules loj dua li dej lwg me me, cov lwg dej yuav muaj adsorbed nyob rau hauv lub qhov, ethanol molecules tsis muaj adsorb tsis suav. Thaum cov dej muaj ethanol adsorbed zoo los ntawm molecular sieve, lub ethanular sieve cov kab kos thiab dhau los ua cov khoom ntshiab ethanol.
Yam khoom:JZ-Zac Molecular Sab Cib
Tshem tawm ntawm hydrogen sulfide thiab Mercaptan
Ntxiv nrog rau hydrogen sulfide, Petroleum cracking roj feem ntau muaj qee qhov nyiaj ntawm cov organic sulfur. Tus yuam sij rau txo cov ntsiab lus Sulfur yog qhov kev raug tshem tawm cov txiv lws suav zoo thiab hydrogen sulfide los ntawm cov roj nyoos. Molecular sab cib tuaj yeem siv tau los adsorb qee cov leej faj-muaj cov tebchaw. Cov kab ke tshaj tawm no suav nrog ob qho:
1- Daim duab xaiv thiab adsorption. Muaj ntau ntau cov kev sib txawv aperture hauv cov qauv molecular, uas tsis tsuas yog muab cov kev sib npaug sab hauv, tab sis kuj tseem yuav txwv qhov kev sib tw ntawm cov molecules nrog loj aperture nkag.
2- polar adsorption, vim muaj cov yam ntxwv ntawm ion teeb meem, yog li muaj cov lus qhuab qhia siab, polar molecules thiab yooj yim polcules molecules. Molecular sab cib yog tsuas yog siv los tshem cov thij los ntawm nkev. Vim tias cov tsis muaj zog polarity ntawm cos, zoo ib yam li cov qauv molecular ntawm co2, Muaj kev sib tw ntawm cov adsorption ntawm cov nplais molecular sab cib nyob rau hauv muaj co2Cov. Txhawm rau kom yooj yim cov txheej txheem thiab txo cov peev txheej peev, molecular sab sleib adsorption sulfate feem ntau yog siv los nrog molecular sab cib lub cev qhuav dej.
Yam khoom:JZ-ZMS9 molecular sieve; Jz-zhs molecular sab cib
Lub aperture ntawm JZ-ZMS3, JZ-ZMS4, JZ-ZMSY4 molecular sab cib me me thiab jz-ZMS9 molecular sab cib nqus Thiol muaj zog heev. Cov txiaj ntsig qhia tau tias kev tshaj tawm muaj peev xwm thiab Adsorption cov khoom nce raws li lub aperture nce.
