Cov pa roj carbon activated tsis raug xaiv tau zoo thiab nws cov ntsej muag yog pom tsis ntev. Feem ntau, nws yuav tsum tau hloov pauv txhua 6 hli mus rau 1 xyoos. Tus nqi ntawm pauv hloov carbon yog siab heev. Cov adsorption muaj peev xwm ntawm cov pa roj carbon tshwj xeeb tuaj yeem ncav ntau dua 100%, thiab nws muaj qhov zoo tsim nyog thiab ruaj khov, yog li kev pab cuam lub neej ntev dua 2-3 xyoos, uas tuaj yeem txuag nqi. Qhov tshwj xeeb thaj tsam thaj chaw ntawm cov roj carbon activated muaj kev sib raug zoo nrog cov txheej txheem pore. Cov kuab tshuaj organic sib txawv siv cov pa roj carbon ua kom sib txawv nrog cov pore sib txawv, yog li txhawm rau kom paub tseeb tias tsis muaj qhov pom tseeb, nws muaj cov yam ntxwv ntawm cov roj me me tsis kam, muaj zog adsorption muaj peev xwm, thiab yooj yim desorption, thiab ua kom cov roj muaj hluav taws xob nrawm nrawm. Cov. Txhawm rau tshem tawm qhov kub nce hauv zos.
Kev kho cov roj khib nyiab ua kom cov pa roj carbon muaj qhov zoo ntawm kev tsim nyog pore loj faib, muaj peev xwm adsorption loj, ceev ceev adsorption ceev, lub zog loj loj, siv hauv lub txaj ruaj khov, qis roj ntws tsis kam, yooj yim desorption thiab tsim dua tshiab, thiab lwm yam, thiab nws tuaj yeem kho feem ntau inorganic gases (xws li sulfide) nyob rau hauv qhov kev nthuav dav dav. Cov pa tshuaj, nitrogen oxides, thiab lwm yam) thiab feem ntau cov organic vapors thiab cov kuab tshuaj muaj lub zog adsorption muaj zog
Qhov ntsuas tshwj xeeb muaj raws li hauv qab no:
Adsorption index: carbon tetrachloride CTC zoo dua li 100%, benzene adsorption: zoo dua li 50%, cov acetone adsorption: ntau dua li 50%
Lub zog: 70-90% lossis 95% tom qab, nyob ntawm daim ntawv thov tshwj xeeb. Tsis yog qhov siab dua qhov ua tau zoo, qhov siab dua lub zog ntawm adsorption yuav poob qis.
Lub ntiajteb txawj nqus tshwj xeeb: qhov siab dua ntawm kev sib tsoo tshwj xeeb, tus nqi ntau dua, qhia tias thaj chaw tshwj xeeb hauv cheeb tsam me dua thiab muaj cov khoom khov dua. Ib yam li ntawd, qhov loj dua qhov kev faib ua feem ntawm ib lub voos xwmfab, hnyav dua nws tau.

Khoom siv: Qhov kev xaiv tseem ceeb yog ntoo lossis thee. Txiv maj phaub plhaub tsis haum vim tias cov kuab tshuaj organic yuav tsum muaj cov roj carbon mesoporous ua kom sov. Yog tias cov thee ua tau zoo ua tiav cov ntsuas saum toj no, tus nqi ntau dua li ntoo. Ordinary coal activated carbon CTC50-70% benzene adsorption: 20-40% ntoo tshuaj ua kom cov pa roj carbon: CTC: 100% -140% benzene adsorption: 45-60% kev sib tsoo tsuas yog ib nrab ntawm cov thee zoo.
