**4 * 8 mesh ziab adsorbent molecular sieve 3a rau tshem tawm cov dej noo**.

Chemxin Molecular Sieve hom 3A yog alkali hlau alumina-silicate; nws yog daim ntawv potassium ntawm hom A siv lead ua qauv. Hom 3A muaj qhov qhib qhov pore zoo ntawm 3 angstroms (0.3nm). Qhov no loj txaus tso cai rau hauv cov dej noo, tab sis tsis suav nrog cov molecules xws li unsaturated hydrocarbons uas tuaj yeem tsim cov polymers; thiab qhov no maximizes lub neej thaum lub cev qhuav dej xws li molecules.

Daim ntawv thov	a) Kev ziab ntawm unsaturated hydrocarbons (xws li ethylene, propylene, butadien) b) Nqus Gas Qhuav c) Kev ziab ntawm cov nkev roj, yog tias COS txo qis yog qhov tseem ceeb, lossis qhov tsawg kawg nkaus co-adsorption ntawm hydrocarbons yuav tsum tau. d) Kev ziab ntawm cov tebchaw muaj zog heev, xws li methanol thiab ethanol e) Qhuav kua cawv f) Static, (non-regenerative) lub cev qhuav dej ntawm cov iav insulating, txawm tias huab cua puv lossis roj puv. g) Kev ziab ntawm CNG.

2. Regeneration:

Chemxin molecular sieve Hom 3A tuaj yeem rov tsim dua los ntawm cua sov hauv cov txheej txheem thermal viav vias; los yog los ntawm kev txo qhov siab nyob rau hauv cov ntaub ntawv ntawm lub siab viav vias txheej txheem.
Txhawm rau tshem tawm cov dej noo los ntawm 3A molecular sieve, yuav tsum muaj qhov kub ntawm 200-230 degree. Ib tug zoo regenerated molecular sieve tuaj yeem muab cov ntsiab lus noo noo hauv qab -100 degree .
Lub qhov hluav taws xob ntau ntawm cov txheej txheem viav vias siab yuav nyob ntawm cov roj tam sim no, thiab nyob ntawm cov xwm txheej ntawm cov txheej txheem.

3. Loj:
3A - Zeolite muaj nyob rau hauv cov hlaws ntawm 1-2 hli (10x18 mesh), 2-3 hli (8x12 mesh), 2.5-5 hli (4x8 mesh) thiab ua hmoov, thiab hauv pellet 1.6 mm 3.2 hli.

4. Nco ntsoov:
Yuav kom tsis txhob damp thiab pre-adsorption ntawm cov organic ua ntej khiav, los yog yuav tsum tau reactivated.
