Lub ntsiab raw khoom ntawm calcined coke yog roj av coke, thiab zoo calcined coke yog tsim los ntawm calcined petroleum coke ntawm kub.

Tom qab calcination ntawm 1250 ℃, cov dej noo thiab volatilization ntawm roj av coke raug tshem tawm, yog li ua kom cov pa roj carbon ntsiab lus ntawm coke, txo cov resistivity ntawm roj av coke thiab ua rau cov porosity zoo dua.Ntxiv mus, tom qab 12 txheej txheem, cov micro-pores hauv txhua cov pa roj carbon monoxide raug kho, kom qhov ntsuas ntawm "super pass, ceev yaj thiab nqus tus nqi" hauv cov txheej txheem ntawm kev siv tau zoo heev.

Cov khoom siv raw ntawm cov khoom zoo calcined coke yog roj av coke, tab sis nws yooj yim heev kom paub qhov txawv lawv.Los ntawm qhov chaw, cov hlau luster ntawm calcined coke muaj zog dua, thiab cov pa roj carbon pores yog pob tshab dua tom qab calcined.Qhov ceev ntawm roj av coke yog me ntsis siab dua thiab hnyav dua li ntawm calcined coke.Cov khoom tseem ceeb ntawm cov roj av coke yog carbon, thiab cov seem yog dej, tshauv, sulfur thiab lwm yam impurities, thiab calcined coke tom qab calcined roj av coke kom tshem tawm ntau cov dej tshauv thiab lwm yam ntxhia impurities, uas yog hais tias, ntau txaus cov calcined raw cov ntaub ntawv, qhov zoo dua cov khoom index ntawm calcined coke, qhov zoo dua rau qhov zoo ntawm cov khoom.

Raws li cov ntsiab lus, cov khoom siv raw ntawm cov khoom siv zoo calcined coke yog roj av coke, thiab cov txheej txheem tswj kub calcination ntawm Jia-carbon cuaj-txheej countercurrent tank calcination rauv tuaj yeem ua kom cov roj av coke zoo calcined thiab tsim cov khoom zoo calcined tom qab 48 teev. ntawm kev tswj kub calcination.
