Lub peev xwm ntawm daim ntawv thov ntawm cov pa roj carbon activated Nws muaj cov qauv tsim pore thiab yog ib qho zoo heev adsorbent. Qhov chaw adsorption ib gram ntawm cov pa roj carbon activated yog sib npaug rau yim lub tsev hais plaub ntaus pob tesniv. Thiab nws cov adsorption yog los ntawm lub cev adsorption thiab tshuaj adsorption. Kev sib deev adsorption yog tiav.
Ntxiv nrog rau cov ntsiab lus carbon, nws cov khoom tseem muaj me me ntawm hydrogen, nitrogen, oxygen thiab tshauv. Nws cov qauv yog tsim los ntawm tsub zuj zuj ntawm rau lub nplhaib uas muaj cov pa roj carbon. Raws li lub microporous ntim thiab thaj chaw siab ntawm cov pa roj carbon activated, kub adsorption activated carbon tuaj yeem tsim los ntawm ntau yam carbonaceous tshuaj, suav nrog ntoo, sawdust, thee, coke, peat, lignin, txiv hmab txiv ntoo pob zeb, tawv plhaub, sucrose Pulp, pob txha. , lignite, roj av residue, thiab lwm yam.
Ntawm lawv, thee thiab txiv maj phaub plhaub tau dhau los ua cov ntaub ntawv siv ntau tshaj plaws los ua cov pa roj carbon activated. Kev tsim cov pa roj carbon activated yog muab faib ua ob txheej txheem.
Thawj txheej txheem suav nrog lub cev qhuav dej thiab carbonization. Tag nrho cov decomposable tshuaj nyob rau hauv nws tsim ib tug tsim microporous qauv thiab ib tug loj loj cheeb tsam, yog li ntawd nws muaj ib tug muaj zog adsorption muaj peev xwm. Lub peev xwm adsorption ntawm activated carbon, ceev adsorption, siab zog, yog siv rau kub extraction thiab lwm yam precious hlau extraction.
Cov pa roj carbon activated tsis tsuas yog muaj lub peev xwm loj adsorption, tab sis kuj ceev adsorption, uas tuaj yeem txhim kho qhov kub rov qab thiab cov khoom siv ntau lawm.
