Tsis ntev los no, CHEMXIN tau txais ib qho kev nug ceev los ntawm ib tus neeg siv khoom ntsib ib qho kev sib tw tab sis tseem ceeb:
Cov lej ntawm cov pa roj carbon monoxide (CO) hauv lawv cov txheej txheem hydrogen tau txo qis kev ua haujlwm thiab lub neej ntawm cov khoom siv hluav taws xob qis.
Txhawm rau daws qhov teeb meem no, CHEMXIN pom zoo kom muaj txiaj ntsig thiab ua pov thawj kev daws teeb meem -13X molecular sieve.
Vim li cas thiaj xaiv 13X Molecular Sieve?
Hauv hydrogen purification systems, cov pa roj noj feem ntau yog cov khoom sib xyaw ua ke, suav nrog hydrogen (H₂), carbon dioxide (CO₂), carbon monoxide (CO), thiab methane (CH₄).
Raws li adsorption thermodynamics, affinity ntawm 13X molecular sieve rau cov gases ua raws li qhov kev txiav txim:
CO₂ > CO > CH₄ ≈ H₂
Hydrogen, ua ib qho me me thiab tsis muaj zog polar molecule, yog NW nyuam qhuav adsorbed thiab tuaj yeem yooj yim dhau ntawm lub txaj adsorbent raws li cov khoom siv roj.
Hauv qhov sib piv, CO molecules cuam tshuam nrog cov cations (xws li Na⁺) hauv 13X lub molecules, tso cai rau lawv raug ntes thiab tshem tawm zoo.
Piv nrog 5A molecular sieve, 13X muaj qhov loj qhov pore loj (~ 10 Å) thiab muaj peev xwm adsorption ntau dua. Qhov no ua rau nws tsim nyog tshwj xeeb rau kev tuav cov roj sib xyaw ua ke thiab ua kom ruaj khov hydrogen purity txawm tias muaj CO₂.
PSA Txheej txheem cej luam
Cov txheej txheem PSA yog ib qho kev sib tw khiav ceev uas tsis yog kev pom yooj yim.
Thaum lub sij hawm adsorption theem, hydrogen kwj nkag mus rau hauv lub adsorption ntauwd uas muaj CHEMXIN 13X molecular sieve nyob rau hauv siab. Nyob rau theem no, CO thiab CO₂ raug xaiv adsorbed vim lub sieve ntawm thaj chaw loj thiab microporous qauv, thaum siab - purity hydrogen hla dhau.
Regeneration & Long -Lub Sij Hawm Ua Haujlwm
Raws li adsorption txuas ntxiv, cov adsorbent maj mam ua saturated. Tom qab ntawd lub kaw lus hloov mus rau theem rov tsim dua tshiab.
CHEMXIN 13X molecular sieve tuaj yeem rov tsim dua los ntawm kev txo qis, lub tshuab nqus tsev, lossis qhov kub thiab txias, tso cai rau cov adsorbed CO kom desorb thiab tshem tawm ntawm qhov system.
Ua tsaug rau qhov thim rov qab ntawm lub cev adsorption, 13X molecular sieve tuaj yeem rov qab siv tau ntau txhiab lub voj voog yam tsis muaj kev ua haujlwm tseem ceeb, ua rau nws raug nqi ntau heev - cov tshuaj muaj txiaj ntsig zoo rau kev lag luam hydrogen purification.
Cov lus pom zoo ua haujlwm tseem ceeb
Txhawm rau kom ntseeg tau tias kev ua tau zoo thiab kev ua haujlwm ntev, ob qho tseem ceeb yuav tsum tau ua tib zoo tswj:
1. Pub Gas Pretreatment
13X molecular sieve yog rhiab heev rau cov kua dej thiab hnyav hydrocarbons.
Nws raug nquahu kom teeb tsa cov pa roj- cov kua cais tawm thiab cov pa roj carbon lim dej ntws los txhawm rau tiv thaiv cov pore txhaws thiab kis kab mob.
2. Kev tswj qhov kub thiab txias
Adsorption yog txheej txheem exothermic, thaum desorption yog endothermic.
Kev tuav lub txaj kub hauv 20-40℃tuaj yeem txhim kho CO adsorption efficiency thiab system stability.
Xaus
Nrog nws cov kev xaiv siab, qhov pore loj loj, zoo heev regenerability, thiab kev pab lub neej ntev, CHEMXIN 13X molecular sieve yog ib qho zoo tagnrho tov rau tshem tawm CO los ntawm hydrogen kwj.
Ua ke nrog PSA thev naus laus zis, nws muab txoj hauv kev txhim khu kev qha, kev lag luam, thiab kev lag luam ua pov thawj kom ua tiav qib siab - purity hydrogen.
