Cov pa roj carbon activated muaj columnar, powdery, thiab granular forms. Nws yog tau los ntawm carbonization ntawm thee, ntoo, tawv txiv hmab txiv ntoo plhaub, txiv hmab txiv ntoo kernels, thiab resin nyob rau hauv cais huab cua nyob rau hauv ib tug kub ntawm 600-900 degree, ua raws li los ntawm oxidation activation nrog huab cua, carbon dioxide, dej vapor, los yog ib tug sib tov ntawm peb gases ntawm 400-900 degree .
Kev siv
Tshuaj purification
Cov pa roj carbon activated feem ntau yog siv rau hauv chav kuaj ntsuas los ntxuav cov kev daws teeb meem ntawm cov organic molecules uas tsis xav tau xim xim organic impurities.
Kev lim dej tshaj cov pa roj carbon monoxide yog siv rau hauv cov txheej txheem tshuaj lom neeg thiab tshuaj loj rau tib lub hom phiaj. Cov carbon yog tov nrog cov tshuaj ces lim tawm los yog immobilized nyob rau hauv lub lim.
Mercury txhuam
Cov pa roj carbon activated, feem ntau infused nrog sulfur los yog iodine, yog dav siv los cuab mercury emissions los ntawm thee-fired power stations, incinerators kho mob, thiab los ntawm natural gas ntawm lub qhov dej. Tab sis mercury-laden activated carbon nthuav tawm qhov teeb meem pov tseg. Yog tias cov pa roj carbon activated muaj tsawg dua 260 ppm mercury, cia nws ruaj khov (piv txwv li, daig hauv pob zeb) rau kev pov tseg. Txawm li cas los xij, cov khoom pov tseg uas muaj ntau dua 260 ppm yog suav tias yog nyob rau hauv cov qib high-mercury subcategory thiab raug txwv tsis pub pov tseg.
