Uru rupapuro rusesengura isoko ya karubone ikora, ikora isesengura ryimbitse ryibikoresho fatizo bya karubone ikora, itangiza uburyo bwo kuranga imiterere ya pore, uburyo bwo kubyaza umusaruro, ingaruka ziterwa niterambere rya karubone ikora, ikanasuzuma ibyavuye mubushakashatsi bwakozwe na karubone ikora pore imiterere yogutezimbere tekinoroji, igamije guteza imbere karubone ikora kugirango igire uruhare runini mugukoresha tekinoroji yicyatsi na karubone nkeya.

Gutegura karubone ikora
Muri rusange, gutegura karubone ikora igabanijwemo ibyiciro bibiri: karubone no gukora

Inzira ya Carbone
Carbonisation bivuga inzira yo gushyushya amakara mbisi ku bushyuhe bwo hejuru irinzwe na gaze ya inert kugirango ibore ibintu bihindagurika kandi ibone ibicuruzwa biva mu kirere hagati. Carbonisation irashobora kugera ku ntego iteganijwe muguhindura ibipimo. Ubushakashatsi bwerekanye ko ubushyuhe bwo gukora ari ikintu cyingenzi kigira ingaruka kuri karubone. Jie Qiang n'abandi. yize ku ngaruka zo gushyushya karubone ku mikorere ya karubone ikora mu itanura rya muffle maze isanga igipimo cyo hasi gifasha kuzamura umusaruro wibikoresho bya karubone no gutanga ibikoresho byiza.

Igikorwa
Carbonisation irashobora gutuma ibikoresho bibisi bigira microcrystalline imiterere isa na grafite kandi ikabyara imiterere yibanze. Nyamara, ibyo byobo birahungabanye cyangwa bigahagarikwa kandi bifungwa nibindi bintu, bikavamo agace gato kihariye kandi bigasaba gukomeza gukora. Gukora ni inzira yo kurushaho kunonosora imiterere ya pore yibicuruzwa bya karubone, bikorwa cyane cyane binyuze mumiti yimiti hagati yuwabikoresheje nibikoresho fatizo: irashobora guteza imbere imiterere ya microcrystalline.

Gukora ahanini binyura mubyiciro bitatu murwego rwo gutungisha imyenge yibikoresho:
(1) Gufungura imyenge yumwimerere ifunze (binyuze mu byobo);
(2) Kwagura imyenge yumwimerere (kwagura pore);
(3) Gukora imyenge mishya (kurema pore);

Izi ngaruka uko ari eshatu ntabwo zikorwa wenyine, ariko zibaho icyarimwe kandi hamwe. Muri rusange, binyuze mu byobo no kurema ibinogo bifasha mu kongera umubare w’imyenge, cyane cyane micropore, ifasha mugutegura ibikoresho byinini bifite umubyimba mwinshi hamwe nubuso bunini bwihariye, mugihe kwaguka kwinshi kwinshi bizatera imyenge guhuza no guhuza , guhindura micropore mu byobo binini. Kubwibyo, kugirango ubone ibikoresho bya karubone bikora hamwe na pore yateye imbere hamwe nubuso bunini bwihariye, birakenewe kwirinda gukora cyane. Uburyo bukoreshwa muburyo bukoreshwa bwa karubone burimo uburyo bwa chimique, uburyo bwumubiri nuburyo bwa fiziki-chimique.

Uburyo bwo gukoresha imiti
Uburyo bwo gukoresha imiti bivuga uburyo bwo kongeramo imiti yimiti kubikoresho fatizo, hanyuma ukabishyushya utangiza imyuka ikingira nka N2 na Ar mu itanura rishyushya kugirango karubone kandi ikore icyarimwe. Abakoresha bakoresha cyane ni NaOH, KOH na H3P04. Uburyo bwo gukoresha imiti bufite ibyiza byubushyuhe buke bwo gutanga umusaruro n’umusaruro mwinshi, ariko kandi bufite ibibazo nko kwangirika kwinshi, ingorane zo gukuraho reagent n’ubutaka bwangiza cyane.

Uburyo bwo gukora kumubiri
Uburyo bwo gukora bwumubiri busobanura karubone yibikoresho bibisi mu itanura, hanyuma bigakorwa hamwe na gaze nka CO2 na H20 byashyizwe mubushyuhe bwinshi kugirango ugere ku ntego yo kongera imyenge no kwagura imyenge, ariko uburyo bwo gukora umubiri bufite ubushobozi buke bwo kugenzura imyenge. imiterere. Muri byo, CO2 ikoreshwa cyane mugutegura karubone ikora kuko ifite isuku, yoroshye kubona kandi igiciro gito. Koresha karubone ya cocout shell nkibikoresho fatizo hanyuma uyikoreshe hamwe na CO2 kugirango utegure karubone ikora hamwe na micropore yateye imbere, hamwe nubuso bwihariye hamwe nubunini bwa pore zingana na 1653m2 · g-1 na 0.1045cm3 · g-1. Imikorere yageze kumikoreshereze ya karubone ikora kuri capacator ebyiri.

Koresha ibuye rya loquat hamwe na CO2 kugirango utegure karubone ikora cyane, nyuma yo gukora kuri 1100 ℃ muminota 30, ubuso bwihariye hamwe nubunini bwa pore yose yageze kuri 3500m2 · g-1 na 1.84cm3 · g-1. Koresha CO2 kugirango ukore ibikorwa bya kabiri kubucuruzi bwa coconut shell ikora karubone. Nyuma yo gukora, micropores yibicuruzwa byarangiye yagabanutse, ingano ya micropore yiyongereye kuva kuri 0.21 cm3 · g-1 igera kuri 0.27 cm3 · g-1, ubuso bwihariye bwiyongereye buva kuri 627.22 m2 · g-1 bugera kuri 822.71 m2 · g-1 , n'ubushobozi bwa adsorption ya fenol yiyongereyeho 23,77%.

Abandi bahanga bize ubushakashatsi bwibanze kumikorere ya CO2. Mohammad n'abandi. [21] basanze ubushyuhe aricyo kintu nyamukuru kigira ingaruka mugihe CO2 ikoreshwa mugukora ibiti bya rubber. Ubuso bwihariye, ubunini bwa pore na microporosity yibicuruzwa byarangiye byabanje kwiyongera hanyuma bigabanuka hamwe nubushyuhe bwiyongera. Indirimbo ya Cheng n'abandi. [22] yakoresheje uburyo bwuburyo bwo gusubiza kugirango asesengure imikorere ya CO2 ya macadamia nut shells. Ibisubizo byerekanaga ko ubushyuhe bwo gukora nigihe cyo gukora bigira uruhare runini mugutezimbere mikorobe ikora.
