Thee -} Raws li cov pa roj carbon monoxide yog tsim los ntawm high- kev kho mob ntawm lub cev thiab tshuaj lom neeg los ua cov khoom siv carbon ntau. Nws yog dav siv nyob rau hauv kev kho dej, huab cua purification, tshuaj xyuas catalysis, thiab lwm daim teb. Cov txheej txheem ntau lawm feem ntau suav nrog cov ntsiab lus tseem ceeb xws li cov khoom siv tseem ceeb xws li cov khoom siv ua ntej, ua kom muaj pa roj carbonancation, ua kom {{{{} ua.
Cov khoom siv raw cereatment yog thawj kauj ruam hauv kev tsim khoom. Nws cuam tshuam nrog crushing, tshuaj ntsuam, thiab qhuav kom ntseeg tau tias muaj kev noo noo thiab tsis kam ua kom muaj kev ua tau zoo ntawm cov txheej txheem tom ntej.
Nyob rau hauv txoj kev sib sau theem, thee yog nias rau hauv ib daim ntawv compacted los ntawm kev ntxiv cov phau ntawv (xws li ntim tar lossis lasnin sulfonate). Cov duab xws li suav nrog txhua kab, granules, lossis hmoov. Kev tswj cov kev ua kom nruj thiab ntsuas kub cuam tshuam rau cov tshuab zog thiab lub zog pore cov qauv ntawm cov carbon activated.
Kev siv hluav taws xob muaj hluav taws xob nrog cua sov rau cov pa hluav taws xob rau 400-600℃rau cov teeb meem tsis muaj zog kom decompose organic teeb meem thiab tsim cov pa roj carbonaceous pob txha pob txha ua ntej. Tus txheej txheem no yuav tsum tau qeeb qeeb ntxiv kom tsis txhob tawg, thaum tsis muaj kev tawg, tawm hauv qab lub hauv paus ntawm lub hauv paus.
Kev ua kom ua kom yog cov kauj ruam tseem ceeb hauv kev ua haujlwm rau cov pa roj carbon nrog nws cov khoom tshaj tawm siab. Dej vapor lossis cov pa roj carbon dioxide yog feem ntau siv los ua kom muaj kev cuam tshuam nrog cov pa roj carbon nyob ntawm 800 {1000 degree, etching ib qho zoo-tsim micropore thiab mesopore qauv. Ua kom lub sijhawm ua kom lub sijhawm thiab lub sijhawm kub ncaj qha cuam tshuam cov cim tseem ceeb xws li thaj chaw thaj (uas tuaj yeem ncav cuag 800-1500 m² / g) thiab iodine tus nqi.
Thaum kawg, Post - kev ua ke nrog cov hmoov av thiab dej ntxuav kom tshem tawm cov hmoov tshauv nrog cov khoom kom qhuav thiab ntsuas kom tau cov khoom tiav. Qee qhov siab -}}}}}}}}}}}}}}}} impecnation hloov kho kom txhim kho kev ua tau zoo rau cov ntawv thov.
Cov txheej txheem ntau lawm rau cov thee - raws cov carbon siv zog ua kom paub meej cov pa roj teeb, thiab purity ua raws li cov ntawv thov sib txawv. Nrog nce kev tiv thaiv ib puag ncig, kev tsim huv thiab cov peev txheej kom huv thiab muaj peev xwm ua tau zoo txuas ntxiv.
