Uburyo bwo gutunganya karubone ikora mubisanzwe igizwe na karubone ikurikirwa no gukora ibintu bya karubone biva mu bimera.Carbonisation ni uburyo bwo kuvura ubushyuhe kuri 400-800 ° C ihindura ibikoresho fatizo kuri karubone hagabanywa ibirimo ibintu bihindagurika no kongera karubone yibikoresho.Ibi byongera ibikoresho imbaraga kandi bigakora imiterere yambere ikenewe niba karubone igomba gukora.Guhindura imiterere ya karubone irashobora kugira ingaruka kubicuruzwa byanyuma.Ubushyuhe bwiyongereye bwa karubone bwongera reaction, ariko icyarimwe bigabanya ingano ya pore ihari.Kugabanuka kwijwi rya pore biterwa no kwiyongera kwikwirakwizwa ryibintu ku bushyuhe bwo hejuru bwa karubone itanga umusaruro wimbaraga za mashini.Kubwibyo, biba ngombwa guhitamo ubushyuhe bukwiye bushingiye kubicuruzwa byifuzwa bya karubone.
Iyi okiside ikwirakwira muri karubone bikavamo gazi igice gifungura imyenge yari yarafunzwe mbere ikanateza imbere karubone imbere.Mugukora imiti, karubone ikorwa mubushyuhe bwinshi hamwe na hydratifike ikuraho hydrogène na ogisijeni muburyo bwa karubone.Gukoresha imiti akenshi bihuza karuboni nintambwe yo gukora, ariko izi ntambwe zombi zirashobora kubaho ukundi bitewe nibikorwa.Ubuso burebure burenga 3.000 m2 / g bwabonetse mugihe ukoresheje KOH nkibikoresho bikora imiti.
Gukora Carbone ivuye mubikoresho bitandukanye.
Usibye kuba adsorbent ikoreshwa mubikorwa byinshi bitandukanye, karubone ikora irashobora kubyazwa umusaruro mubutunzi bwibikoresho bitandukanye, bigatuma igicuruzwa kidasanzwe kuburyo gishobora gukorerwa mubice byinshi bitandukanye bitewe nibikoresho fatizo bihari.Bimwe muri ibyo bikoresho birimo ibishishwa by'ibimera, amabuye y'imbuto, ibikoresho by'ibiti, asfalt, karbide y'icyuma, umukara wa karubone, imyanda isigara ivuye mu mwanda, hamwe n'ibisigazwa bya polymer.Ubwoko butandukanye bwamakara, asanzweho muburyo bwa 5 karubone ifite imiterere ya pore yateye imbere, irashobora gutunganywa kugirango ikore karubone ikora.Nubwo karubone ikora ishobora gukorwa mubintu hafi ya byose bibisi, birahenze cyane kandi byangiza ibidukikije kubyara karubone ikora mubikoresho byimyanda.Carbone ikora ikozwe mubishishwa bya cocout byagaragaye ko ifite umuvuduko mwinshi wa micropore, bigatuma iba ibikoresho bikoreshwa cyane mubisabwa aho hakenewe ubushobozi bwa adsorption.Sawdust nibindi bikoresho bishaje byibiti nabyo birimo mikorobe yateye imbere cyane nibyiza bya adsorption kuva murwego rwa gaze.Gukora karubone ikora ivuye mu myelayo, plum, amata, n'amabuye y'amashaza bitanga adsorbents cyane hamwe no gukomera gukomeye, kurwanya abrasion hamwe na micropore nyinshi.Ibice bya PVC birashobora gukoreshwa mugihe HCl yakuweho mbere, bikavamo karubone ikora ni adsorbent nziza kubururu bwa methylene.Carbone ikora niyo yakozwe kuva mumapine.Kugirango utandukanye intera yagutse ishoboka ibanziriza, biba ngombwa gusuzuma imiterere yumubiri yavuyemo nyuma yo gukora.Iyo uhisemo preursor ibintu bikurikira bifite akamaro: ubuso bwihariye bwubuso bwa pore, ingano ya pore nogukwirakwiza ingano ya pore, ibigize nubunini bwa granules, hamwe nimiterere ya chimique / imiterere yubuso bwa karubone.
Guhitamo ibanziriza neza kubisabwa neza ni ngombwa cyane kuko itandukaniro ryibikoresho byabanjirije kwemerera kugenzura imiterere ya karubone.Ibibanziriza bitandukanye birimo urugero rwa macropore (> 50 nm,) 6 igena reaction zabo.Iyi macropores ntabwo ikora neza kuri adsorption, ariko kuboneka kwayo bituma imiyoboro myinshi yo gukora micropore mugihe cyo gukora.Byongeye kandi, macropore itanga inzira nyinshi kuri adsorbate molekules kugirango igere kuri micropores mugihe cya adsorption.
