Cov tshuaj coke koob muaj cov qauv zoo li koob thiab ua los ntawm cov roj slurry los ntawm cov chaw ua roj lossis cov thee tar pitch. Nws yog cov khoom siv tseem ceeb rau kev ua cov electrodes graphite uas siv rau hauv cov txheej txheem tsim cov hlau siv lub tshuab hluav taws xob arc (EAF). Qhov kev tshuaj xyuas kev lag luam coke koob no xav txog kev muag khoom los ntawm kev lag luam graphite, kev lag luam roj teeb, thiab lwm yam. Peb qhov kev tshuaj xyuas kuj xav txog kev muag khoom ntawm cov tshuaj coke koob hauv APAC, Tebchaws Europe, North America, South America, thiab MEA. Xyoo 2018, qhov kev lag luam graphite muaj feem ntau ntawm kev lag luam, thiab qhov sib txawv no yuav txuas ntxiv mus rau lub sijhawm kwv yees. Cov yam xws li kev thov nce ntxiv rau cov electrodes graphite rau txoj kev EAF ntawm kev tsim hlau yuav ua lub luag haujlwm tseem ceeb hauv qhov kev lag luam graphite kom tswj hwm nws txoj haujlwm kev lag luam. Tsis tas li ntawd, peb daim ntawv qhia kev lag luam coke koob thoob ntiaj teb saib cov yam xws li kev nce ntxiv ntawm lub peev xwm ua roj, kev nce ntxiv ntawm kev siv cov tsheb ntsuab, kev nce ntxiv ntawm kev thov rau UHP graphite electrodes. Txawm li cas los xij, qhov kev sib txawv ntawm kev thov thiab kev muab khoom lithium uas nthuav dav hauv kev coj kev nqis peev hauv kev lag luam thee vim yog cov cai tiv thaiv kev ua qias tuaj ntawm cov pa roj carbon, kev hloov pauv ntawm cov roj av nyoos thiab cov nqi thee yuav cuam tshuam kev loj hlob ntawm kev lag luam koob coke dhau lub sijhawm kwv yees.
Kev Lag Luam Thoob Ntiaj Teb Needle Coke: Txheej Txheem Cej Luam
Kev thov rau UHP graphite electrodes nce ntxiv
Cov hluav taws xob graphite siv rau hauv cov ntawv thov, xws li cov cub tawg arc thiab cov cub tawg ladle rau kev tsim cov hlau, cov khoom siv tsis yog hlau, thiab cov hlau. Lawv kuj tseem siv rau hauv EAFs rau kev tsim hlau. Cov hluav taws xob graphite tuaj yeem tsim tau siv roj av coke lossis koob coke. Cov hluav taws xob graphite raug faib ua lub zog ib txwm, lub zog siab, lub zog siab heev, thiab UHP raws li cov yam ntxwv xws li resistivity, hluav taws xob conductivity, thermal conductivity, kev tiv thaiv rau oxidation thiab thermal shock, thiab lub zog kho tshuab. Tawm ntawm txhua hom graphite electrodes. UHP graphite electrodes tau txais kev saib xyuas hauv kev lag luam hlau. Qhov kev thov rau UHP electrodes no yuav ua rau kev nthuav dav ntawm kev lag luam thoob ntiaj teb koob coke ntawm CAGR ntawm 6% thaum lub sijhawm kwv yees.
Kev tshwm sim ntawm cov hlau ntsuab
Qhov kev tso pa tawm ntawm CO2 yog qhov teeb meem loj uas kev lag luam hlau thoob ntiaj teb ntsib. Txhawm rau daws qhov teeb meem no, ntau yam kev tshawb fawb thiab kev txhim kho (R&D) tau ua tiav. Cov kev tshawb fawb thiab kev txhim kho no ua rau muaj cov hlau ntsuab. Cov kws tshawb fawb tau pom ib txoj kev ua hlau tshiab uas tuaj yeem tshem tawm cov pa CO2 tag nrho. Hauv cov txheej txheem ua hlau ib txwm muaj, thaum lub sijhawm tsim hlau, muaj pa luam yeeb, carbon, thiab nplaim taws ntau heev. Cov txheej txheem ua hlau ib txwm muaj CO2 ob npaug ntawm qhov hnyav ntawm hlau. Txawm li cas los xij, cov txheej txheem tshiab tuaj yeem ua tiav kev ua hlau nrog xoom emissions. Pulverized thee txhaj tshuaj thiab carbon capture thiab khaws cia (CCS) thev naus laus zis yog ib qho ntawm lawv. Kev txhim kho no xav tias yuav muaj kev cuam tshuam zoo rau kev loj hlob ntawm kev lag luam tag nrho.
Kev sib tw ua lag luam
Nrog rau ob peb lub tuam txhab loj, kev lag luam thoob ntiaj teb ntawm cov koob txhaj tshuaj tau sib sau ua ke. Cov kev tshuaj xyuas zoo no yog tsim los pab cov neeg siv khoom txhim kho lawv txoj haujlwm hauv kev lag luam, thiab raws li qhov no, daim ntawv tshaj tawm no muab cov kev tshuaj xyuas ntxaws ntxaws ntawm ntau lub tuam txhab tsim cov koob txhaj tshuaj, uas suav nrog C-Chem Co. Ltd., GrafTech International Ltd., Mitsubishi Chemical Holdings Corp., Phillips 66 Co., Sojitz Corp., thiab Sumitomo Corp.
Tsis tas li ntawd xwb, daim ntawv qhia txog kev tshuaj xyuas kev lag luam ntawm cov tshuaj yeeb muaj cov ntaub ntawv hais txog cov qauv thiab cov teeb meem uas yuav tshwm sim tom ntej uas yuav cuam tshuam rau kev loj hlob ntawm kev lag luam. Qhov no yog los pab cov tuam txhab tsim tswv yim thiab siv txhua lub sijhawm loj hlob uas yuav tshwm sim.
