Raws li ib qho tseem ceeb ntawm cov tshuab hluav taws xob compressed, adsorption cov tshuab ziab khaub ncaws tshwj xeeb los ntawm cov cua kom huv si los ntawm cov cua tshuab kom huv si. Adsorbents ua haujlwm ua cov tub ntxhais ntawm cov tshuab ziab khaub ncaws no. Hauv qab no yog thawj cov adsorbents tam sim no siv nyob rau hauv adsorption wryers:
1.Qhib Alumina:
Ua kom Alumina dominates cov adsorption lub tshuab ua kom lub tshuab ua kom zoo dua vim nws qhov muaj peev xwm siab tshaj plaws, muaj zog siv zog, thiab ua kua dej rau hauv dej. Nws cov qauv siv microporous matelially cuab kav dej noo, thiab nws tuaj yeem tsim thiab siv tau zoo.
2.Molecular sab cib:
Molecular sieves yog cov hluavtaws aluminium matosilicates nrog cov uniform micropores uas muaj qhov ntau tuaj yeem tswj tau precisely. Piv rau urctated alumina, molecular sieve nthuav tawm cov dej muaj zog adsorption muaj peev xwm, tshwj xeeb hauv cov av noo ib puag ncig, xa cov khoom lag luam kom qhuav.
3.Silica Gel:
Silica gel yog ib tug tshaj tawm cov adsorbent nrog cov capillary pores, muab cov khoom noo noo Adsorption cov khoom.
Li cas los xaiv cov adsorbent txoj cai?
Xaiv cov adsorbent zoo tshaj plaws yuav tsum tau ntsuas cov lus hauv qab no:
1.Compressed cuaNtws thiab siab: Cov nqi tsheb siab dua thiab cov ntawv tshaj tawm xav tau Adsorbents nrog muaj peev xwm loj dua.
2.drying yuav tsum tau: Txo cov lus tso tawm hauv Dew taw tes tas yuav tsum muaj cov khoom muaj zog zoo li cov tub rog molecular.
3. Cov nqi siv: Xav txog Adsorbent Nqe, Kev Siv hluav taws xob Kev Siv Zog Tshaj Tawm, thiab kev ua neej.
4. Thuaj Ib puag ncig: Qhov xwm txheej hnyav (piv txwv li, qhov kub thiab sov, av noo) yuav tsum tau adsorbed nrog kev ua kom tau txais txiaj ntsig.
Hauv cov ntsiab lus, ua haujlwm Alumina, molecular sieves, thiab silica gel txhua yam muaj qhov tseem ceeb thiab kev txwv. Cov neeg siv yuav tsum xaiv adsorbents raws cov kev xav tau tshwj xeeb kom ntseeg tau tias, ua lub tshuab ua haujlwm ua haujlwm zoo thiab cov cua zoo compressed.
