Hom Activated Carbon thiab xaiv cov pa roj carbon zoo rau koj daim ntawv thov
Lignite Coal - Qhib Pore Structure
Ib qho khoom siv feem ntau siv los ua cov pa roj carbon monoxide yog lignite thee. Piv nrog rau lwm cov thee, lignite yog softer thiab sib dua, uas muab ntau qhov pore loj thaum lub sij hawm ua kom tiav. Qhov dav thiab qhib pore qauv ua rau lignite raws li cov pa roj carbon monoxide zoo tshaj plaws ntawm kev tshem tawm cov khoom loj lossis cov organic molecules.
Txiv maj phaub - Tight Pore Structure
Lwm cov khoom siv feem ntau siv cov pa roj carbon monoxide yog cov txiv maj phaub plhaub. Txiv maj phaub yog ib qho nyuaj heev thiab ntom, yog li nws ua tiav ntau qhov pores me me thaum ua kom tsis txhob muaj qhov pores loj dua pom hauv lignite. Cov txheej txheem nruj dua ntawm cov txiv maj phaub raws li cov pa roj carbon activated ua rau nws zoo tshaj plaws ntawm kev tshem tawm me me los yog siab zog cov organic molecules.
Bituminous Coal - Nruab nrab Pore Structure
Bituminous thee kuj nquag siv los ua cov khoom pib rau cov pa roj carbon activated. Bituminous thee yog denser dua lignite thee tab sis softer dua txiv maj phaub; xws li, nws muaj kev sib xyaw ua ke ntawm ob qhov loj thiab me pores tom qab ua kom tiav. Qhov ntau ntawm qhov pore qhov ntau thiab tsawg ua rau bituminous thee raws li GAC muaj txiaj ntsig ntawm kev tshem tawm cov kab mob organic ntawm ntau qhov ntau thiab tsawg thiab cov duab ib txhij.
GAC tuaj yeem tsim los ntawm ntau yam khoom pib los tshem tawm ntau yam kab mob, tab sis tsis hais seb hom activated carbon los yog daim ntawv thov nyob rau hauv qhov twg, GAC yuav tsum tau rov siv dua lossis hloov ib ntus kom ntseeg tau tias cov phiaj xwm sib xyaw yuav raug kho kom zoo.
Txhim kho cov pa roj carbon activated
Thaum GAC ntxuav thiab ntxuav cov kua thiab roj, nws cov txiaj ntsig tau ploj zuj zus mus.
Raws li cov organic tebchaw yog adsorbed, lawv siv qhov chaw nyob rau hauv cov qauv ntxeem tau ntawm cov pa roj carbon activated. Thaum kawg yuav tsis muaj chaw seem ntawm cov pa roj carbon activated rau cov kab mob uas yuav tsum tau tuav. Thaum qhov no tshwm sim, GAC yuav tsum raug tshem tawm thiab hloov pauv kom lub kaw lus tuaj yeem ua haujlwm ntxiv raws li qhov xav tau.
Yuav kom tswj tau cov pa roj carbon lim dej zoo dua, nws raug nquahu kom cov qauv coj mus kuaj ib xyoos ib zaug. Lub hom phiaj ntawm cov txheej txheem yog los sau cov qauv kom raug los ntawm lub hauv paus ntawm lub lim. Tom qab ntawd GAC tuaj yeem kuaj xyuas cov haujlwm seem, uas yog txiav txim siab siv qhov ntsuas iodine. Cov ntaub ntawv keeb kwm qhia tau hais tias ib zaug tus lej iodine nyob nruab nrab ntawm 450 thiab 550, GAC yuav tsum tau rov ua dua lossis hloov pauv yav tom ntej.
Ib qho tshwj xeeb tshaj plaws ntawm granular activated carbon yog tias nws tuaj yeem rov ua dua tom qab nws dhau los ua cov khoom paug. Los ntawm cov txheej txheem hu ua "reactivation," cov kab mob adsorbed raug tshem tawm ntawm GAC los ntawm qhov kub thiab txias. Nrog cov khoom paug tawm, lub peev xwm adsorptive ntawm cov pa roj carbon activated tau rov qab los thiab nws tuaj yeem muab tso rau hauv kev pabcuam txuas ntxiv ua kom huv huv cov kua thiab cov kwj deg.
