Thawj qhov kev lag luam ib lab-tuj hydrogen-raws li txoj haujlwm ntsug rauv tau ua tiav tiav thiab muab tso rau hauv kev tsim khoom ntawm Baosteel's Zhanjiang Hlau thiab Hlau.

Thawj qhov kev lag luam hauv ib lab-tuj hydrogen-raws li qhov hluav taws xob qhov hluav taws xob tau ua tiav tiav thiab muab tso rau hauv kev tsim khoom ntawm Baosteel's Zhanjiang Hlau thiab Hlau.

Thaum Lub Kaum Ob Hlis 23rd, thawj qhov project hauv tsev hydrogen-based ntsug rauv nrog lub peev xwm ntawm ib lab tons tau ua tiav ignited thiab muab tso rau hauv kev tsim khoom ntawm Baosteel's Zhanjiang Hlau thiab Hlau, kos ib kauj ruam tseem ceeb hauv kev ua qauv qhia thiab kev hloov pauv ntawm Tuam Tshoj txoj kev lag luam steel rau ntsuab. thiab tsawg-carbon. Qhov project no sawv cev rau qhov loj tshaj plaws kev sib xyaw cov kab ntau lawm hauv Suav teb uas siv ntau qhov chaw siv roj thiab thaum kawg tau txais tag nrho cov hydrogen rau kev lag luam ntawm cov hlau txo qis, ua txoj hauv kev hauv kev hloov pauv ntawm cov txheej txheem hlau metallurgical.
Baosteel's Zhanjiang Iron thiab Steel's ib lab-tuj hydrogen-raws li ntsug rauv qhov project pib tsim thaum Lub Ob Hlis 15, 2022. Cov chaw tseem ceeb suav nrog lub tshuab hluav taws xob ntsug lub cev, ntsug rauv qhov chaw thau khoom thiab tshem tawm, cov khoom cua txias, cov khoom siv hluav taws xob, cov khoom siv raw khoom. thiab cov khoom tiav cov khoom tso tawm, nrog rau cov kev txhawb nqa xws li cov khoom siv pellet, lub zog rau pej xeem pabcuam, thiab cov ntaub ntawv kaw lus. Nrog rau kev tsom mus rau kev ywj pheej kev koom ua ke thiab kev tsim kho tshiab, Baosteel's Zhanjiang Hlau thiab Hlau siv nws tus kheej tsim cov ntaub ntawv refractory thiab domestically tsim ntsug conveyor siv nrog qhov siab tshaj plaws ntawm 112 meters thawj zaug. Qhov project cov cuab yeej siv thiab cov chaw muaj tus nqi domestication tshaj 70%, nquag txhawb kev loj hlob ntawm kev tsim khoom lag luam hauv tsev. Baosteel's Zhanjiang Hlau thiab Hlau, hauv kev sib koom tes zoo nrog Tuam Tshoj Steel International, Shanghai Baoye, thiab lwm yam koom nrog, tsis tu ncua kov yeej cov teeb meem thiab cov fwj, ua kom muaj kev tswj hwm kev nyab xeeb ntawm qhov project, zoo, thiab kev vam meej. Qhov project tau ua tiav thiab muab tso rau hauv kev ua haujlwm ntau tshaj li ob lub hlis ua ntej ntawm txoj kev npaj thawj zaug, ib zaug ua kom pom qhov "Zhangang ceev."
Hydrogen yog ib qho kev cog lus zoo tshaj plaws ntawm lub zog huv. Piv nrog rau cov pa roj carbon metallurgy ib txwm muaj, hydrogen metallurgy siv hydrogen ua ob qho tib si roj thiab txo tus neeg sawv cev, ua rau cov hlau refining kom tsis txhob muaj kev vam khom ntawm fossil fuels thiab hais txog carbon emissions ntawm qhov chaw. Hauv Baowu's carbon-neutral metallurgical roadmap, hydrogen-based vertical furnaces, as the core of hydrogen metallurgy, raug txheeb xyuas tias yog ib txoj hauv kev tseem ceeb rau carbon-neutral metallurgical technology. Nws tau kwv yees tias tom qab qhov project tau muab tso rau hauv kev ua haujlwm, piv rau qhov sib npaug ntawm cov khoom siv hlau uas siv cov txheej txheem blast furnace, nws tuaj yeem txo cov pa roj carbon dioxide ntau dua 500,000 tons hauv ib xyoos.
Qhov txawv ntawm cov txheej txheem ntawm kev siv cov roj ntsha los npaj cov txheej txheem txo cov pa roj thoob ntiaj teb, qhov project tau txais Baowu lub ntiaj teb pioneering "Hydrogen Metallurgy Electrofusion Smelting Process" (HyRESP). Los ntawm cov txheej txheem ntsuab thiab luv luv xws li hydrogen-nplua nuj roj purification, hydrogen-raws li ntsug rauv txo qis, carbon dioxide capture, thiab ncaj qha txo cov khoom txias, qhov project innovatively siv ib tug series ntawm cov thev naus laus zis, suav nrog "kev txo qis coke cub roj refining," "Kev faib tawm yooj yim ntawm cov txheej txheem gases," thiab "txias-lub xeev ncaj qha txo cov khoom siv hlau pov tseg thiab daim ntawv thov." Qhov kev ua tiav ntawm cov kev paub no yuav ua rau muaj kev sib koom ua ke ntawm kev ywj pheej thiab kev loj hlob ntawm tag nrho hydrogen metallurgical thev naus laus zis, tsim cov txheej txheem carbon hlau qis nrog cov tswv cuab kev txawj ntse, uas tuav qhov tseem ceeb rau kev loj hlob ntsuab thiab qis-carbon ntawm kev lag luam steel.
