Lub lim tiam no, kev ua lag luam raw khoom hloov pauv, tus nqi ntawm cov roj av coke uas tsis muaj sulfur tau qhia txog kev poob qis, tus nqi tam sim no yog 6050-6700 yuan / ton, tus nqi roj thoob ntiaj teb hloov pauv qis, kev ua lag luam wat-and-see siab nce, cuam tshuam los ntawm kev sib kis, qee lub tuam txhab kev thauj mus los thiab kev txwv, kev xa khoom tsis du, yuav tsum txo tus nqi ntawm kev khaws cia; Tus nqi ntawm koob coke tau ruaj khov ib ntus, tus nqi ntawm cov thee asphalt txuas ntxiv nce, tus nqi ntawm cov tuam txhab ntsuas thee tau hloov pauv hnyav, thiab tsis muaj haujlwm tshiab tau pib rau lub sijhawm tam sim no. Tus nqi ntawm cov roj slurry uas tsis muaj sulfur tau txo qis, thiab qhov kev nyuaj siab ntawm cov tuam txhab roj tau yooj yim dua. Tus nqi coke uas tsis muaj sulfur txuas ntxiv poob qis cuam tshuam rau kev xav yuav khoom ntawm cov tuam txhab tsis zoo, tsis ncaj qha ua rau qhov nyuaj ntawm cov koob coke kom thawb siab, kev ua lag luam koob coke tuav lub siab tos thiab saib.
Lub lag luam khoom siv electrode tsis zoo ruaj khov, qhov kev thov ntawm cov tuam txhab roj teeb downstream tsis siab, thiab lub hom phiaj ntawm kev tshem tawm cov khoom khaws cia muaj zog. Tam sim no, feem ntau ntawm lawv tsuas yog yuav tsum yuav, khaws cia kom zoo, thiab tus nqi muaj zog. Cov khoom siv raw superposition kawg ntawm cov nqi coke sulfur qis poob qis, lub khw "yuav nce tsis txhob yuav nqis" lub siab xav nyob hauv txoj haujlwm tseem ceeb, kev yuav khoom downstream qeeb qeeb, qhov kev lag luam tiag tiag yog ceev faj dua.
Lub lim tiam no, tus nqi ntawm cov khoom siv graphite anode cuav tau poob qis, tus nqi ntawm cov khoom nruab nrab tau poob 2750 yuan / ton, tus nqi lag luam tam sim no yog 50500 yuan / ton. Tus nqi ntawm cov khoom siv raw tseem poob qis, thiab tus nqi ua graphitization kuj tau poob qis, uas tsis tuaj yeem muab kev txhawb nqa tus nqi rau cov khoom siv graphite anode cuav. Txawm hais tias nws tau xaus rau lub xyoo, cov tuam txhab electrode tsis zoo tsis tau nce cov khoom muag zoo li xyoo dhau los, feem ntau vim tias qee lub tuam txhab tau khaws cov khoom ntau dua thaum ntxov, thiab cov khoom muag tau zoo. Tam sim no, lub siab xav mus rau lub tsev rau khoom yog qhov tseem ceeb, thiab kev khaws cia yog ceev faj. Vim yog kev nthuav dav ntawm cov khoom siv anode thaum ntxov, yuav muaj kev tso tawm ntau xyoo tom ntej. Nyob ze rau thaum kawg ntawm lub xyoo, kev lag luam tsis zoo tau pib sib tw rau cov xaj ntev ntawm lub xyoo tom ntej, thiab qee lub tuam txhab xaiv los sib tw rau cov xaj ntawm tus nqi qis dua kom ntseeg tau tias cov txiaj ntsig ntawm lub xyoo tom ntej.
Kev lag luam graphitization
Cov nqi tau nkag mus rau theem qis dua
Raws li cov ntaub ntawv, txij li lub quarter thib peb, vim yog qhov kev tso tawm ntawm lub peev xwm tsim khoom, tus nqi graphitization tau nkag mus rau theem qis dua. Tam sim no, tus nqi nruab nrab ntawm cov graphitization tsis zoo yog 19,000 yuan / ton, uas yog 32% qis dua tus nqi hauv thawj ib nrab ntawm lub xyoo no.
Kev tsim cov graphite tsis zoo yog ib qho txheej txheem tseem ceeb hauv kev ua cov graphite cuav, thiab nws lub peev xwm tsim khoom zoo cuam tshuam rau qhov kev muab cov graphite cuav tiag tiag. Vim tias graphite yog qhov txuas ntawm kev siv hluav taws xob ntau, lub peev xwm tsim khoom feem ntau faib rau hauv Inner Mongolia, Sichuan thiab lwm qhov chaw uas tus nqi hluav taws xob pheej yig. Xyoo 2021, vim yog txoj cai tswj hwm ob tog hauv tebchaws thiab kev txwv hwj chim, lub peev xwm vaj tse ntawm thaj chaw tsim cov graphite tseem ceeb xws li Inner Mongolia yuav raug puas tsuaj, thiab tus nqi kev loj hlob ntawm kev muab khoom qis dua li qhov kev thov qis dua. Ua rau muaj qhov sib txawv loj ntawm kev muab khoom graphite, cov nqi ua graphite nce siab.
Raws li kev soj ntsuam, tus nqi graphitization tau raug txo qis tas li txij li lub quarter thib peb, feem ntau vim tias graphitization tau nkag mus rau lub sijhawm ntawm kev tso tawm peev xwm tsim khoom ntau lawm txij li ib nrab xyoo 2022, thiab qhov sib txawv ntawm kev muab graphitization tau maj mam nqaim.
Lub peev xwm ua graphitization uas tau npaj tseg yuav ncav cuag 1.46 lab tons hauv xyoo 2022 thiab 2.31 lab tons hauv xyoo 2023.
Lub peev xwm txhua xyoo ntawm cov chaw tsim cov graphitization tseem ceeb txij li xyoo 2022 txog 2023 tau npaj raws li nram no:
Sab Hauv Mongolia: Yuav muaj peev xwm tshiab rau xyoo 2022. Lub peev xwm ua graphitization zoo yuav yog 450,000 tons hauv xyoo 2022 thiab 700,000 tons hauv xyoo 2023.
Sichuan: Lub peev xwm tshiab yuav raug muab tso rau hauv kev tsim khoom hauv xyoo 2022-2023. Lub peev xwm ua graphitization zoo yuav yog 140,000 tons hauv xyoo 2022 thiab 330,000 tons hauv xyoo 2023.
Guizhou: Lub peev xwm tshiab yuav raug muab tso rau hauv kev tsim khoom thaum xyoo 2022-2023. Lub peev xwm ua graphitization zoo yuav yog 180,000 tons hauv xyoo 2022 thiab 280,000 tons hauv xyoo 2023.
Los ntawm cov ntaub ntawv tam sim no ntawm qhov project, qhov kev nce ntxiv ntawm lub peev xwm electrode tsis zoo yav tom ntej yog feem ntau yog kev koom ua ke ntawm graphite dag, feem ntau nyob hauv Sichuan, Yunnan, Inner Mongolia thiab lwm qhov chaw.
Xav tias kev tsim cov graphite tau nkag mus rau lub sijhawm tso tawm peev xwm tsim khoom hauv xyoo 2022-2023. Xav tias kev tsim cov graphite cuav yuav tsis raug txwv rau yav tom ntej, thiab tus nqi yuav txuas ntxiv rov qab mus rau qhov tsim nyog.
