Cov Khoom Ntawm Cov Pa roj carbon uas ua haujlwm
Thaum xaiv cov pa roj carbon activated rau ib daim ntawv thov tshwj xeeb, ntau yam ntxwv yuav tsum tau xav txog:
Cov qauv ntawm qhov hws
Cov qauv ntawm cov pa roj carbon activated sib txawv thiab feem ntau yog qhov tshwm sim ntawm cov khoom siv thiab txoj kev tsim khoom.¹ Cov qauv ntawm cov qhov, ua ke nrog cov zog nyiam, yog qhov uas tso cai rau kev nqus dej tshwm sim.
Kev Nyuaj/Kev Sib Txhuam
Qhov nyuaj/kev sib txhuam kuj yog ib qho tseem ceeb hauv kev xaiv. Ntau daim ntawv thov yuav xav kom cov pa roj carbon activated muaj lub zog siab thiab tiv taus kev tawg (kev tawg ntawm cov khoom ua me me). Cov pa roj carbon activated uas tsim los ntawm cov plhaub txiv maj phaub muaj qhov nyuaj tshaj plaws ntawm cov pa roj carbon activated.
Cov Khoom Uas Nqus Tau
Cov khoom siv nqus ntawm cov pa roj carbon activated muaj ntau yam ntxwv, suav nrog lub peev xwm nqus tau, tus nqi ntawm kev nqus, thiab tag nrho cov txiaj ntsig ntawm cov pa roj carbon activated.
Nyob ntawm seb daim ntawv thov (kua los yog roj), cov khoom no yuav qhia los ntawm ntau yam, suav nrog tus lej iodine, thaj chaw nto, thiab Carbon Tetrachloride Activity (CTC).
Qhov Ceev Pom Tseeb
Txawm hais tias qhov ceev pom tseeb yuav tsis cuam tshuam rau qhov adsorption ib chav qhov hnyav, nws yuav cuam tshuam rau qhov adsorption ib chav ntim.
Cov dej noo
Qhov zoo tshaj plaws, qhov ntau ntawm cov dej noo uas muaj nyob hauv cov pa roj carbon activated yuav tsum poob rau hauv 3-6%.
Cov ntsiab lus tshauv
Cov tshauv ntawm cov pa roj carbon activated yog qhov ntsuas ntawm qhov inert, amorphous, inorganic, thiab tsis siv tau ntawm cov khoom siv. Cov tshauv ntawm cov pa roj carbon activated yuav tsum qis li qis tau, vim tias qhov zoo ntawm cov pa roj carbon activated nce ntxiv thaum cov tshauv ntawm cov pa roj carbon activated txo qis.
Tus nqi pH
Tus nqi pH feem ntau yog ntsuas los kwv yees qhov kev hloov pauv thaum ntxiv cov pa roj carbon activated rau hauv cov kua.
Qhov Loj ntawm Cov Khoom Me Me
Qhov loj ntawm cov khoom me me muaj feem cuam tshuam ncaj qha rau kev nqus kinetics, cov yam ntxwv ntws, thiab kev lim dej ntawm cov pa roj carbon activated.
Kev Tsim Cov Pa roj carbon ua kom muaj zog
Cov pa roj carbon activated yog tsim los ntawm ob txoj hauv kev tseem ceeb: carbonization thiab activation.
Kev ua kom carbonization
Thaum lub sijhawm carbonization, cov khoom siv raw raug decomposed los ntawm cua sov hauv ib puag ncig inert, ntawm qhov kub qis dua 800 ºC. Los ntawm kev ua gasification, cov ntsiab lus xws li oxygen, hydrogen, nitrogen, thiab sulfur, raug tshem tawm ntawm cov khoom siv.
Kev ua kom rov ua dua
Cov khoom siv carbonized, lossis char, yuav tsum tau qhib kom ua haujlwm kom tag nrho cov qauv pore. Qhov no yog ua los ntawm kev oxidizing lub char ntawm qhov kub ntawm 800-900 ºC nyob rau hauv qhov muaj huab cua, carbon dioxide, lossis pa.
Nyob ntawm seb cov khoom siv los ua, cov txheej txheem ntawm kev tsim cov pa roj carbon activated tuaj yeem ua tiav los ntawm kev siv cua sov (lub cev / pa) ua kom sov, lossis kev ua kom sov tshuaj. Txawm li cas los xij, lub qhov cub rotary tuaj yeem siv los ua cov khoom siv mus rau hauv cov pa roj carbon activated.
