Nyob rau yav tav su ntawm Lub Kaum Ob Hlis 14, Tuam Tshoj Baowu, Rio Tinto thiab Tsinghua University tau koom ua ke 3rd China Steel Low Carbon Development Goals thiab Pathways Rhiav los tham txog txoj hauv kev rau kev hloov pauv cov pa roj carbon tsawg hauv kev lag luam steel.
Txij li thaum thawj zaug ntau lawm ntau tshaj 100 lab tons hauv 1996, Tuam Tshoj tau ua lub ntiaj teb cov hlau loj tshaj plaws tsim lub teb chaws rau 26 xyoo sib law liag.Tuam Tshoj yog lub chaw tsim khoom ntawm lub ntiaj teb kev lag luam steel thiab qhov chaw noj ntawm lub ntiaj teb kev lag luam steel.Nyob rau hauv lub ntsej muag ntawm Tuam Tshoj 30-60 ob lub hom phiaj carbon, kev lag luam steel tseem txhawb nqa ntsuab qis carbon innovation, nyob rau hauv uas kev npaj, kev lag luam synergy, thev naus laus zis innovation breakthroughs thiab zog efficiency txhim kho yog txhua yam tseem ceeb.
Yuav ua li cas kev lag luam steel ua tiav cov pa roj carbon ntau thiab cov pa roj carbon nruab nrab?
Raws li kev lag luam tseem ceeb ntawm kev lag luam hauv lub tebchaws, kev lag luam steel kuj yog ib qho ntawm cov ntsiab lus tseem ceeb thiab cov teeb meem hauv kev txhawb nqa cov pa roj carbon emission txo.Wang Hao, Tus Lwm Thawj Coj ntawm Carbon Summit thiab Carbon Neutral Promotion Division ntawm Department of Environmental Resources ntawm National Development thiab Reform Commission, tau taw qhia ntawm lub rooj sib tham hais tias kev lag luam steel yuav tsum tsis txhob ncav cuag qhov siab tshaj plaws rau kev mus txog lub ncov, cia nyob ib leeg txo cov khoom tsim tau rau lub hom phiaj ntawm kev txo qis emission, tab sis yuav tsum coj cov pa roj carbon monoxide ua lub sijhawm tseem ceeb los txhawb kev hloov pauv ntsuab thiab cov pa roj carbon tsawg thiab kev txhim kho zoo ntawm kev lag luam steel.
Huang Guiding, Tus Lwm Thawj Coj ntawm Tuam Tshoj Hlau thiab Hlau Kev Lag Luam Association, tau hais hauv lub rooj sib tham tias txhawm rau txhawb kev ntsuab thiab cov pa roj carbon tsawg, Tuam Tshoj txoj kev lag luam steel tau nquag txhawb peb txoj haujlwm steel loj: muaj peev xwm hloov pauv, ultra-low emission thiab lub zog loj. efficiency.Txawm li cas los xij, Tuam Tshoj cov peev txheej thiab lub zog muaj txiaj ntsig ntawm cov khoom seem tsis txaus, nplua nuj nyob hauv cov thee thiab cov neeg tsis zoo hauv cov roj thiab roj, txiav txim siab tias qhov xwm txheej quo ntawm Tuam Tshoj txoj kev lag luam steel, uas yog tus thawj tswj hwm los ntawm cov txheej txheem ntev ntawm blast furnaces thiab converters, yuav raug tswj kom zoo heev. ntev.
Huang tau hais tias, kev txhawb nqa tob zog ntawm kev txuag hluav taws xob thiab cov txheej txheem cov cuab yeej tshiab thiab kev hloov pauv thiab hloov kho dua tshiab, tag nrho cov txheej txheem kev siv hluav taws xob txhim kho, yog qhov tseem ceeb tam sim no ntawm kev lag luam steel kom txo qis carbon, tab sis kuj yog tus yuam sij rau cov pa roj carbon tsawg tsis ntev los no. transformation thiab upgrading ntawm Tuam Tshoj cov hlau.
Thaum Lub Yim Hli xyoo no, Pawg Neeg Saib Xyuas Kev Lag Luam Hlau Tsawg Carbon Ua Haujlwm Tshaj Tawm tau tshaj tawm "Carbon Neutral Vision thiab Low Carbon Technology Roadmap rau Kev Lag Luam Hlau" (tom qab no hu ua "Roadmap"), uas qhia meej txog rau txoj hauv kev rau kev hloov pauv cov pa roj carbon tsawg. ntawm Tuam Tshoj txoj kev lag luam steel, uas yog kev txhim kho kev siv hluav taws xob, kev siv cov khoom siv, kev ua kom zoo dua qub thiab kev tsim kho tshiab, cov txheej txheem smelting, cov khoom iteration thiab kho dua tshiab, thiab kev siv cov pa roj carbon monoxide thiab khaws cia.
Lub Roadmap faib cov txheej txheem ntawm kev siv cov kev hloov pauv ntawm cov pa roj carbon ob hauv Tuam Tshoj txoj kev lag luam hlau ua plaub theem, thawj theem ntawm kev txhawb nqa kev ua tau zoo ntawm cov pa roj carbon monoxide los ntawm 2030, sib sib zog nqus decarbonization los ntawm 2030 txog 2040, sprinting rau huab cua txo los ntawm 2040 txog 2050, thiab txhawb cov pa roj carbon nruab nrab ntawm 2050 txog 2060.
Fan Tiejun, tus thawj tswj hwm ntawm Metallurgical Industry Planning and Research Institute, tau faib txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam steel rau hauv ob lub sijhawm thiab tsib theem.Ob lub sij hawm yog lub sij hawm kom muaj nuj nqis thiab lub sij hawm zoo, lub sij hawm kom muaj nuj nqis tau muab faib ua theem kev loj hlob thiab kev txo qis, thiab lub sij hawm zoo tau muab faib rau hauv cov txheej txheem nrawm dua, lub zog tiv thaiv ib puag ncig theem thiab kev txhim kho qis carbon. theem.Nyob rau hauv nws txoj kev xav, Tuam Tshoj txoj kev lag luam steel tam sim no nyob rau hauv qhov txo qis, ua kom nrawm dua theem thiab ntxiv dag zog rau kev tiv thaiv ib puag ncig ntawm peb theem sib tshooj.
Fan Tiejun tau hais tias, raws li Metallurgical Planning thiab Research Institute txoj kev nkag siab thiab kev tshawb fawb, Tuam Tshoj txoj kev lag luam steel twb tau tawm ntawm cov ntsiab lus tsis meej thiab cov lus hais tsis muaj, thiab cov tuam txhab feem ntau tau pib siv cov kev nqis tes ua ob zaug rau hauv cov haujlwm tseem ceeb ntawm cov hlau. cov lag luam.Ib tug xov tooj ntawm domestic steel mills twb pib sim hydrogen metallurgy, CCUS tej yaam num thiab ntsuab zog tej yaam num.
Kev siv cov khib nyiab steel thiab hydrogen metallurgy yog cov lus qhia tseem ceeb
Kev lag luam insiders taw qhia tias nyob rau hauv tus txheej txheem ntawm low-carbon transformation ntawm steel kev lag luam, kev siv ntawm cov khoom seem steel thiab kev loj hlob ntawm hydrogen metallurgy thev naus laus zis yuav yog ib qho ntawm ob qho tseem ceeb cov lus qhia rau kev tawg ntawm carbon txo nyob rau hauv kev lag luam.
Xiao Guodong, tus pab saib xyuas dav dav ntawm Tuam Tshoj Baowu Group thiab tus thawj coj ntawm Carbon Neutral, tau taw qhia ntawm lub rooj sib tham tias hlau yog cov khoom siv ntsuab rov ua dua tshiab thiab kev lag luam hlau tau yog lub hauv paus tseem ceeb los txhawb kev txhim kho lub ntiaj teb niaj hnub no.Cov khoom siv thoob ntiaj teb cov khoom siv hlau tsis txaus los ua kom tau raws li cov kev xav tau ntawm kev txhim kho kev sib raug zoo, thiab kev tsim cov hlau pib los ntawm ore yuav nyob twj ywm rau hauv lub ntsiab rau lub sijhawm ntev yav tom ntej.
Xiao tau hais tias txoj kev loj hlob ntawm ntsuab qis-carbon steel thiab hlau cov khoom tsim khoom tsis yog tsuas yog txiav txim siab los ntawm cov peev txheej tam sim no thiab lub zog, tab sis kuj tseem tsim lub hauv paus rau cov tiam tom ntej kom muaj peev xwm muaj cov ntaub ntawv siv hlau ntau dua.Txhawm rau ua kom tiav ob lub hom phiaj ntawm kev lag luam steel, kev hloov pauv ntawm lub zog qauv yog qhov tseem ceeb heev, cov uas hydrogen zog yuav ua lub luag haujlwm tseem ceeb.
Mr. Huang, Tus Lwm Thawj Coj ntawm Tuam Tshoj Steel Association, tau taw qhia tias hydrogen metallurgy tuaj yeem ua rau qhov tsis zoo ntawm cov khoom siv tsis txaus hauv cov teb chaws tsim, tshwj xeeb tshaj yog nyob rau hauv cov teb chaws xws li Tuam Tshoj, thaum txo hydrogen ncaj qha hlau tuaj yeem yog qhov kev xaiv tseem ceeb rau kev sib txawv. thiab txhawb nqa cov peev txheej hlau hauv cov txheej txheem luv luv.
Hauv kev xam phaj yav dhau los nrog 21st Century Business Herald, Yanlin Zhao, tus thawj coj ntawm Tuam Tshoj kev tshawb fawb ntawm Bank of America Securities, tau hais tias hlau yog kev lag luam uas muaj cov pa roj carbon ntau tshaj plaws tshwj tsis yog lub zog hluav taws xob, thiab hydrogen, raws li lub zog hloov pauv, muaj. muaj peev xwm ntau dua los hloov coking thee thiab coke yav tom ntej.Yog tias qhov project ntawm hydrogen es tsis txhob ntawm cov thee tuaj yeem ua tiav thiab siv dav hauv kev tsim cov hlau mills, nws yuav ua rau muaj kev cuam tshuam loj thiab txoj hauv kev loj hlob zoo rau kev hloov pauv ntawm cov pa roj carbon tsawg ntawm kev lag luam steel.
Raws li Fan Tiejun, cov pa roj carbon ncov hauv kev lag luam steel yog qhov teeb meem kev txhim kho, thiab kom ua tiav cov pa roj carbon monoxide nyob rau hauv kev lag luam steel, thawj qhov kev daws teeb meem yog kev hloov kho hauv kev tsim kho;Thaum nyob rau hauv theem txo cov pa roj carbon monoxide, cov thev naus laus zis siab heev yuav tsum tau siv cov txheej txheem, thiab cov theem decarbonization yuav tsum muaj qhov tshwm sim ntawm kev hloov kho thev naus laus zis, suav nrog hydrogen metallurgy, thiab daim ntawv thov loj ntawm cov txheej txheem hluav taws xob hluav taws xob steelmaking;Nyob rau hauv cov pa roj carbon nruab nrab theem ntawm kev lag luam steel, nws yog ib qho tsim nyog rau Cov pa roj carbon nruab nrab theem ntawm kev lag luam steel yuav tsum tau hais txog kev sib koom ua ke ntawm kev sib koom ua ke hauv cheeb tsam thiab ntau qhov kev qhuab qhia, kev sib koom ua ke ntawm cov txheej txheem tshiab, CCUS thiab daim ntawv thov ntawm hav zoov carbon dab dej.
Ntxuam Tiejun tau hais tias kev hloov pauv ntawm cov pa roj carbon tsawg ntawm kev lag luam steel yuav tsum tau ua ke nrog kev tsim kho kev npaj, cov kev xav tau ntawm kev lag luam sab saud thiab qis qis, kev loj hlob hauv nroog, thiab kev tsim kho thev naus laus zis, thiab txij li kev lag luam steel yuav sai sai no suav nrog cov pa roj carbon. kev lag luam, kev lag luam yuav tsum tau muab cov pa roj carbon monoxide ua lag luam los txhawb kev txuag hluav taws xob thiab kev txo qis emission los ntawm kev lag luam kev xav.
