Hmoov tau cov pa roj carbon (PAC) yog cov khoom siv roj carbonaceous nrog cov chaw siab tshwj xeeb thiab muaj peev xwm ua tiav muaj peev xwm. Nws yog dav siv nyob rau hauv kev kho dej, huab cua huv, thiab kev tswj cov pa phem. Nws txoj kev npaj thiab kev ua tau zoo ua kom zoo muaj qhov cuam tshuam tseem ceeb ntawm nws cov ntaub ntawv thov.
Cov kev npaj loj rau PAC suav nrog kev ua kom lub cev, tshuaj lom neeg ua kom muaj kuab, thiab kev sib xyaw ntawm ob qho tib si. Kev ua kom lub cev feem ntau yog siv cov dej vapor, pa roj carbon dioxide, lossis ua kom tiav cov pa roj carbon daus (800-1 Qib Ib Leeg (8}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Cov qauv tsim. Hom qauv no yooj yim, tab sis lub sijhawm ua kom muaj zog ntev thiab cov khoom adsorption yog qhov txwv. Kev siv tshuaj lom neeg siv tshuaj lom neeg tshuaj lom neeg xws li phosphoric acid, potureium precursor ntawm cov roj hmab precursor los tsim cov qauv microfous thiab mesoporous nplua nuj. Cov carbon accomated ua los ntawm hom no muaj qhov muaj peev xwm tshwj xeeb hauv cheeb tsam thiab muaj peev xwm ua tshuaj ntsuab yuav cuam tshuam nws txoj kev nyab xeeb. Nyob rau hauv xyoo tsis ntev los no, txoj kev sib xyaw ua ke tau ua ke ntawm qhov zoo ntawm kev faib tshuaj lub cev thiab tshuaj lom neeg, ntxiv txhim kho tag nrho cov kev ua tau zoo ntawm cov carbon ua haujlwm.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov, hmoov activated carbon yog feem ntau yog siv los tshem tawm cov pa phem, thiab cov pig tshwm sim los ntawm cov pa hluav taws xob sai sai hauv cov dej muaj kuab paug. Nws tseem ua lub luag haujlwm tseem ceeb hauv kev pov tseg roj purification, purification ntawm cov tshuaj hauv cov hluav taws xob, thiab decolorization hauv kev lag luam khoom noj.
Nyob rau hauv lub neej yav tom ntej, hmoov actived carbon ntau lawm siv tshuab yuav tsim kho ntawm cov kev siv roj thiab muaj txiaj ntsig ntau. Los ntawm kev txhim kho cov txheej txheem ua kom muaj zog thiab txhim kho cov nqi tshiab, nws cov nqi kev tshaj tawm yuav raug txo kom tau raws li kev tiv thaiv ib puag ncig ib puag ncig.
