Cov Carbon Molecular Sieve CMS yog cov khoom siv carbon nrog qhov tshwj xeeb pore loj tis thiab nto chemistry uas tso cai rau lub sieve xaiv adsorb ib feem ntawm cov roj sib tov los ntawm lub cev los yog tshuaj adsorption nyob rau hauv txawv siab thiab kub tej yam kev mob. Adsorption yog tsub zuj zuj ntawm cov pa roj los yog kua molecules ntawm ib tug khoom nto, nyob ntawm seb ib puag ncig nyob rau hauv uas nws yog siv thiab cov hom ntawm gases raug cais. Lub hauv paus ntsiab lus ntawm adsorption hauv Carbon Molecular Sieve CMS yog tsim los ntawm kev sib cuam tshuam ntawm cov molecules, xws li van der Waals force, dipole-dipole kev sib cuam tshuam, induction force, thiab lwm yam. Cov rog no ua rau cov roj molecules adsorbed rau ntawm cov pa roj carbon monoxide. molecular sieve, yog li ua tiav kev sib cais ntawm cov roj sib tov.
Lub cev adsorption yog hais txog cov txheej txheem los ntawm cov roj molecules yog adsorbed rau ntawm qhov chaw ntawm Carbon Molecular Sieve CMS los ntawm cov rog intermolecular uas tsis koom nrog kev tsim cov tshuaj bonds. Cov yam ntxwv ntawm lub cev adsorption yog tias cov txheej txheem adsorption yog thim rov qab, cov cua sov adsorption me me, cov adsorption ceev ceev, thiab cov txheej txheem adsorption tsis cuam tshuam los ntawm cov khoom siv tshuaj. Chemisorption yog hais txog cov txheej txheem los ntawm cov roj molecules reacts chemically nrog rau saum npoo ntawm Carbon Molecular Sieve CMS los tsim cov tshuaj bonds. Cov yam ntxwv ntawm chemisorption yog tias cov txheej txheem adsorption yog irreversible, lub adsorption tshav kub yog loj, adsorption ceev yog qeeb, thiab cov txheej txheem adsorption cuam tshuam los ntawm cov tshuaj lom neeg ntawm cov pa roj carbon molecular sieve. Lub hauv paus ntsiab lus ntawm adsorption thermodynamics yog lub hauv paus theoretical rau kev kawm txog kev hloov tshav kub thiab adsorption equilibrium nyob rau hauv cov txheej txheem adsorption. Raws li cov adsorption isotherm, cov khoom adsorption ntawm cov pa roj carbon molecular sieves ntawm qhov sib txawv ntawm qhov kub thiab txias tuaj yeem nkag siab, txhawm rau ua kom zoo dua qhov adsorption tej yam kev mob.
Adsorption enrichment yog hais txog cov txheej txheem uas Carbon Molecular Sieve CMS nce qhov concentration ntawm ib feem hauv cov roj sib tov los ntawm adsorption. Cov nyhuv no ua rau Carbon Molecular Sieve CMS muaj txiaj ntsig zoo rau kev sib cais roj thiab kev ua kom huv. Adsorption yog hais txog cov txheej txheem uas cov roj molecules yog adsorbed rau ntawm qhov chaw ntawm Carbon Molecular Sieve CMS, thaum desorption yog hais txog cov txheej txheem uas cov roj molecules adsorbed yog desorbed los ntawm qhov chaw ntawm Carbon Molecular Sieve CMS. Ob txoj kev no yog thim rov qab thiab cuam tshuam los ntawm qhov kub, siab, roj concentration thiab lwm yam. Raws li cov txheej txheem adsorption zuj zus, lub peev xwm adsorption ntawm Carbon Molecular Sieve CMS maj mam txo. Yuav kom rov qab tau nws cov khoom adsorption, Carbon Molecular Sieve CMS yuav tsum tau rov tsim dua. Cov txheej txheem kev tsim dua tshiab muaj xws li thermal regeneration, chemical regeneration thiab lwm yam. Regenerated Carbon Molecular Sieve CMS tuaj yeem muab tso rau hauv kev siv, yog li rov siv cov peev txheej. Nyob rau tib lub sijhawm, rau Carbon Molecular Sieve CMS uas tau poob nws cov khoom adsorption, nws tseem yuav tsum ua kom tsim nyog kho thiab rov ua dua kom tsis txhob muaj kuab paug rau ib puag ncig.
