Kodi kafukufuku waukadaulo ndi njira zotani zamtsogolo za graphitized petroleum coke?

Kafukufuku wamtsogolo waukadaulo ndi njira zopangira graphitized petroleum coke makamaka zimayang'ana kwambiri mbali zotsatirazi:

Ukadaulo Woyera Kwambiri ndi Wosadetsedwa Kwambiri

Mwa kukonza njira zochepetsera kuzizira kwa mafuta ndi njira zochotsera sulfure m'madzi, sulfure, phulusa, ndi zina zodetsedwa mu petroleum coke zitha kuchepetsedwa. Mwachitsanzo, Sinopec Qingdao Refinery yachepetsa sulfure kufika pansi pa 0.3%, zomwe zakwaniritsa kufunikira kwa petroleum coke yopanda sulfure m'gawo latsopano la mphamvu. M'tsogolomu, ndikofunikira kupititsa patsogolo njira zochotsera phulusa kuti muchepetse phulusa kuchokera pa 8-10 wt% kufika pansi pa 1 wt%, motero kuwonjezera kuyera kwa zinthu ndi kukhazikika kwa magwiridwe antchito.

Kupanga Zinthu Zapamwamba Kwambiri Mwamakonda

Zinthu zapadera za petroleum coke ziyenera kupangidwa kuti zigwiritsidwe ntchito m'malo apamwamba monga zinthu za lithiamu batire anode ndi zinthu zochepetsera mphamvu za silicon. Mwachitsanzo, coke yamagetsi ya batire iyenera kukwaniritsa zizindikiro monga kuchuluka kwa sulfure <0.5% ndi kuchuluka kwa phulusa <0.3% kuti iwonjezere kuchuluka kwa mphamvu ya batire ndi moyo wa nthawi yozungulira. Kuphatikiza apo, coke yamafuta ya photovoltaic imafuna mapangidwe abwino a ma pore kuti iwonjezere kugwira ntchito bwino komanso kuchepetsa ndalama zopangira zinthu za silicon.

Kukonza Mozama ndi Kugwiritsa Ntchito Mowonjezera Mtengo

Zinthu zopangidwa mozama monga needle coke ndi ulusi wa kaboni ziyenera kupangidwa kuti ziwonjezere phindu la mafakitale. Monga zinthu zofunika kwambiri zopangira ma electrode a graphite amphamvu kwambiri, needle coke yawona kukula kwakukulu kwa kufunikira mkati mwa kupanga zitsulo zamoto zamagetsi ndi unyolo watsopano woperekera mphamvu. Mwachitsanzo, Jinzhou Petrochemical yapanga needle coke kwa nthawi yayitali, kukwaniritsa zosowa zamsika zapamwamba.

Ukadaulo Wopanga Zinthu Zosamalira Chilengedwe Komanso Zobiriwira

Poyankha mfundo zokhwima kwambiri zachilengedwe, njira zopangira zinthu zomwe siziwononga chilengedwe komanso zomwe sizigwiritsa ntchito mphamvu zambiri ziyenera kupangidwa. Mwachitsanzo, electrolysis ya mchere wosungunuka imatha kupangitsa kuti kutentha kukhale kotsika kuposa 1000°C, kuchepetsa kugwiritsa ntchito mphamvu ndi 40% poyerekeza ndi njira zachikhalidwe zotenthetsera kwambiri komanso zopanikizika kwambiri (zoposa 2000°C) komanso kugwiritsidwa ntchito pazinthu zosiyanasiyana zopangira mpweya. Kuphatikiza apo, ukadaulo woyambitsa mpweya m'malo osungira mpweya umaletsa kusonkhana kwa madzi mwa kuyambitsa tinthu tating'onoting'ono tosagwira ntchito, kuchepetsa nthawi yoyambitsa mpweya kukhala maola 2-8 ndikuchepetsa kugwiritsa ntchito mphamvu.

Ukadaulo Wolondola wa Kapangidwe ka Ma Pore

Kudzera mu njira zoyendetsera mphamvu zamagetsi ndi njira zogwiritsira ntchito mankhwala osokoneza bongo mkati mwa malo, kapangidwe ka ma pore a ma carbon okhala ndi ma porous a petroleum coke kangathe kuyendetsedwa kuti kawongolere magwiridwe antchito a zinthu. Mwachitsanzo, kugwiritsa ntchito njira yolumikizira mphamvu ya H₂O/CO₂ imapanga kapangidwe ka micropore-mesopore (chiŵerengero cha mesopore cha 20%-60%) kuti chigwirizane ndi zochitika zosiyanasiyana zogwiritsira ntchito. Nthawi yomweyo, kuyambitsa NH₃ kapena H₃PO₄ kumathandiza kuti atomu ya nitrogen/phosphorus igwiritsidwe ntchito (magawo ogwiritsira ntchito mankhwala osokoneza bongo a 1-5 pa%), ndikuwonjezera mphamvu yoyendetsera ntchito komanso ntchito ya pamwamba.

Kukulitsa kwa Ntchito mu Gawo Latsopano la Mphamvu

Zipangizo zatsopano zamagetsi monga kaboni wopangidwa ndi petroleum coke ndi kaboni wa supercapacitor ziyenera kupangidwa. Mwachitsanzo, kaboni wokhala ndi porous carbon wochokera ku petroleum coke, monga "mnzake wagolide" wa ma silicon anode, umathandizira kukhazikika kwa kayendedwe ka madzi ndi 300% kudzera mu malamulo a kapangidwe ka ma pore (kapangidwe ka ma pore otsekedwa ka 50-500 nm) kuti ateteze kufalikira kwa kuchuluka kwa silicon. Akuyembekezeka kuti kukula kwa msika wapadziko lonse lapansi kudzapitirira 120 biliyoni yuan pofika chaka cha 2030, ndi kuchuluka kwa pachaka kwa 25%.

Ukadaulo Wopanga Wanzeru Komanso Wodzipangira Wokha

Kugwiritsa ntchito intaneti ya zinthu (IoT) ndi ukadaulo wa blockchain kungathandize kupititsa patsogolo ntchito yopanga zinthu komanso ubwino wa zinthu. Mwachitsanzo, kusunga zinthu mwanzeru kumathandiza kuyang'anira zinthu nthawi yeniyeni, ndikuwonjezera liwiro la mayankho ndi 50%. Kutsata bwino kwa blockchain kumapereka satifiketi ya "carbon footprint" ya zinthu, kukwaniritsa zofunikira za EU ESG.
