Calcined petroleum coke siv
Calcined petroleum coke (CPC) plays lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam. Nws yog tsim los ntawm raw roj av coke (CPC) los ntawm cov txheej txheem kub-calcination.
Nws yog muab rho tawm los ntawm raw roj av coke (RPC) los ntawm ib tug high-kub calcination txheej txheem, uas tshem tawm volatile hydrocarbons thiab txhim kho qhov ceev thiab hluav taws xob zog ntawm coke.
Cov txheej txheem no tuaj yeem tshem tawm cov tsis muaj zog hydrocarbons thiab nce qhov ceev thiab conductivity ntawm coke. Hauv qab no yog cov ntsiab lus ntawm kev siv tseem ceeb ntawm calcined petroleum coke.
1. Aluminium ntau lawm
- Anodes hauv electrolytes.
Daim ntawv thov tseem ceeb: Calcined petroleum coke feem ntau yog siv hauv kev lag luam txhuas los tsim cov anodes, uas yog ib feem tseem ceeb ntawm electrolytic txo ntawm aluminium oxide.
Lub luag haujlwm: Nws muab cov anode nrog cov khoom siv hluav taws xob tsim nyog thiab kev ua haujlwm ruaj khov kom tso cai kom muaj txiaj ntsig zoo ntawm tam sim no los ntawm electrolyzer.
Advantage: High carbon purity thiab zoo heev conductivity txhim kho efficiency thiab zoo ntawm txhuas ntau lawm.
2. Steel manufacturing
- Carbonizer.
Daim ntaub ntawv: Calcined petroleum coke yog siv los ua carbonizer hauv cov txheej txheem steelmaking los kho cov ntsiab lus ntawm cov hlau. Taw qhia rau hauv molten hlau thaum ladle metallurgy.
Muaj nuj nqi: Qhov no yuav pab ua kom tiav cov pa roj carbon specification rau ntau qib steel thiab txhim kho cov khoom xws li hardness thiab tensile lub zog.
Qib: Tshwj xeeb tseem ceeb rau kev tsim cov hlau zoo rau kev lag luam tsheb lossis kev tsim kho.
3.Graphite Electrode Ntau Lawm
-Raw Material
Daim ntawv thov: Calcined petroleum coke yog cov khoom siv tseem ceeb rau kev tsim cov graphite electrodes rau hluav taws xob arc furnaces (EAF).
Cov txheej txheem ntau lawm: Calcined roj av coke yog tov nrog coal tar pitch, extruded, roasted thiab graphitized los ua ib tug electrode uas muaj peev xwm tiv taus kub thiab hluav taws xob loads ntawm EAF. Nws muaj peev xwm tiv taus qhov kub thiab txias thiab hluav taws xob loads hauv hluav taws xob arc rauv.
Qhov tseem ceeb: High purity calcined petroleum coke xyuas kom meej tias cov electrode tsis muaj impurities, uas txhim kho nws cov efficiency thiab kev pab lub neej nyob rau hauv hnyav ib puag ncig.
4. Titanium dioxide (TiO2) ntau lawm
- Txo tus neeg sawv cev.
Kev Ua Haujlwm: Calcined petroleum coke ua raws li tus neeg sawv cev txo qis hauv kev tsim cov titanium dioxide los ntawm chlorination, hloov titanium tetrachloride (TiCI4) rau hauv titanium dioxide.
Cov txiaj ntsig: Nws cov ntsiab lus carbon siab thiab qib impurity tsawg ua rau nws zoo tagnrho rau kev tsim cov purity siab TiOz, uas yog siv dav hauv cov xim, coatings, plastics thiab ntawv.
6. Foundry carburizer
- Additive.
Siv: Hauv cov chaw tsim khoom, calcined petroleum coke yog ntxiv rau cov hlau yaj ua cov carburizer kom nce cov ntsiab lus carbon thiab kho cov tshuaj lom neeg kawg ntawm cov casting.
Kev cuam tshuam: Qhov no txhim kho cov khoom siv hluav taws xob ntawm cov hlau cam khwb cia, ua rau nws tsim nyog rau ntau yam kev siv, xws li cov cav cav, cov kav dej thiab cov khoom siv tshuab.
7. Lub Zog Cia thiab Roj Cell
- Muaj peev xwm siv tau.
Kev Tsim Kho: Kev tshawb fawb tau tshawb fawb txog kev siv cov roj av calcined hauv cov ntawv thov kev siv hluav taws xob, suav nrog cov khoom siv hauv cov roj teeb lithium-ion thiab roj hlwb. Qhov zoo: Nws cov purity siab thiab conductivity ua rau nws cov khoom cog lus rau kev txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm lub zog cia khoom.
Lub zog: Nws siab purity thiab conductivity ua rau nws cov khoom cog lus rau kev txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm lub zog cia khoom.
Xaus
Calcined petroleum coke yog cov khoom siv ntau yam nrog ntau yam kev siv hauv aluminium ntau lawm, steel manufacturing, graphite electrodes, thiab ntau lwm yam lag luam. Nws cov khoom tshwj xeeb, suav nrog cov ntsiab lus siab carbon, hluav taws xob conductivity, thiab qib impurity tsawg, ua rau nws yog ib qho khoom siv tsis tseem ceeb rau cov txheej txheem no. Raws li kev lag luam hloov zuj zus thiab cov thev naus laus zis tshiab tshwm sim, qhov kev thov rau cov roj av coke zoo yuav tsum loj hlob, ntxiv dag zog rau nws lub luag haujlwm hauv kev siv niaj hnub no.
