Kwinjiza karubone ikora

Carbone ikora (AC) bivuga ibikoresho bya karubone cyane bifite ubukana bwinshi nubushobozi bwo kubaza biva mu biti, ibishishwa bya cocout, amakara, hamwe na conone, nibindi. AC ni imwe muma adsorbents ikoreshwa cyane mubikorwa bitandukanye kugirango ikureho imyanda myinshi. biva mu mazi no mu kirere.Kuva, AC ikomatanya ivuye mubuhinzi n’imyanda, byagaragaye ko ari inzira nziza kubisanzwe byakoreshwaga bidasubirwaho kandi bihenze.Mugutegura AC, inzira ebyiri zifatizo, karubone nogukora, birakoreshwa.Mubikorwa byambere, ababanjirije bakorerwa ubushyuhe bwinshi, hagati ya 400 na 850 ° C, kugirango birukane ibice byose bihindagurika.Ubushyuhe bwo hejuru cyane bukuraho ibintu byose bitarimo karubone kubibanjirije nka hydrogène, ogisijeni, na azote mu buryo bwa gaze na tari.Ubu buryo butanga char ifite karubone nyinshi ariko ubuso buke hamwe nubushake.Ariko, intambwe ya kabiri ikubiyemo gukora ya char synthesize char.Kongera ubunini bwa pore mugihe cyibikorwa birashobora gushyirwa mubice bitatu: gufungura imyenge yabanje kutagerwaho, iterambere rya pore rishya ukoresheje guhitamo, no kwagura imyenge ihari.
Mubisanzwe, uburyo bubiri, bwumubiri nubumashini, bikoreshwa mugukora kugirango ubone ubuso bwifuzwa hamwe nubushake.Gukora kumubiri bikubiyemo gukora char ya karubone ukoresheje gaze ya okiside nkumwuka, dioxyde de carbone, hamwe na parike mubushyuhe bwinshi (hagati ya 650 na 900 ° C).Dioxyde de Carbone isanzwe ikunzwe kubera imiterere yayo yera, kuyikoresha byoroshye, hamwe nuburyo bugenzurwa na 800 ° C.Uburinganire bwa pore burashobora kuboneka hamwe na dioxyde de carbone ugereranije na parike.Nyamara, kubikorwa byumubiri, amavuta arakunzwe cyane ugereranije na karuboni ya dioxyde de AC kuva AC ifite ubuso buringaniye bushobora kubyara.Bitewe na molekile ntoya y'amazi, ikwirakwizwa ryayo muburyo bwa char ibaho neza.Gukora ukoresheje parike byagaragaye ko bikubye inshuro ebyiri kugeza kuri eshatu kurenza karuboni ya dioxyde de degre imwe yo guhinduka.
Nyamara, uburyo bwa chimique burimo kuvanga preursor hamwe nibikorwa bikora (NaOH, KOH, na FeCl3, nibindi).Izi mikorere ikora nka okiside kimwe ningingo zangiza.Muri ubu buryo, karuboni no gukora bikorwa icyarimwe icyarimwe ugereranije n'ubushyuhe bwo hasi 300-500 ° C ugereranije nuburyo bugaragara.Nkigisubizo, bigira ingaruka kubora pyrolytike hanyuma, hanyuma, bivamo kwaguka kunoza imiterere myiza hamwe numusaruro mwinshi wa karubone.Inyungu ninshi za chimique hejuru yuburyo bwumubiri nubushyuhe buke busabwa, imiterere ya microporosity, ubuso bunini, hamwe nigihe cyo kurangiza igihe cyo kurangiza.
Ubusumbane bwuburyo bwo gukoresha imiti bushobora gusobanurwa hashingiwe ku cyitegererezo cyatanzwe na Kim na bagenzi be bakorana [1] hakurikijwe microdomaine zitandukanye zishinzwe gushinga micropore ziboneka muri AC.Kurundi ruhande, mesopore yateye imbere mukarere ka intermicrodomain.Mubigeragezo, bakoze karubone ikora ivuye muri fenoline ikoresheje imiti (ukoresheje KOH) hamwe nogukora kumubiri (ukoresheje parike) (Ishusho 1).Ibisubizo byerekanaga ko AC ikomatanyirijwe hamwe na KOH ifite ubuso bungana na 2878 m2 / g ugereranije na 2213 m2 / g ukoresheje moteri.Mubyongeyeho, ibindi bintu nkubunini bwa pore, ubuso bwubuso, ingano ya micropore, nubugari bwikigereranyo cya pore byose wasangaga ari byiza mubihe byakoreshwaga na KOH ugereranije na parike ikora.

Itandukaniro hagati ya AC Yateguwe kuva mumashanyarazi (C6S9) no gukora KOH (C6K9), byasobanuwe muburyo bwa microstructure.

Ukurikije ingano yubunini nuburyo bwo gutegura, birashobora gushyirwa mubwoko butatu: AC ikoreshwa na AC, granular AC, na AC isaro.AC ikora ikozwe muri granules nziza ifite ubunini bwa mm 1 hamwe nimpuzandengo ya diameter ya 0.15-0.25 mm.Granular AC ifite ubunini bugereranije nubuso buto bwo hanze.Granular AC ikoreshwa mubyiciro bitandukanye byamazi hamwe na gaz ya gaz ikoreshwa bitewe nubunini bwabyo.Icyiciro cya gatatu: isaro AC isanzwe ikomatanyirizwa mu kibanza cya peteroli ifite diameter iri hagati ya 0.35 na 0.8 mm.Azwiho imbaraga nyinshi zubukanishi hamwe nubutaka buke.Irakoreshwa cyane mubikorwa byo kuryama bisukuye nko kuyungurura amazi kubera imiterere yayo.
