Dontho la mafuta limayamba ulendo wochokera kumunda wamafuta, kupita ku njira zophikira kuti lisinthe kukhala mafuta a coke, kenako n’kusinthidwanso kudzera mu graphitization kuti lipange zinthu za graphite zoyera kwambiri. Pamapeto pake, limagwiritsa ntchito mbali ya anode ya mabatire amagetsi (EV), zomwe zimapatsa magalimoto mphamvu. Njirayi ikuwonetsa kusintha kwa mafuta kuchokera ku gwero lamphamvu lachikhalidwe kupita ku chinthu chapamwamba, zomwe zimapangitsa kuti mayendedwe amtsogolo azitha kuyenda bwino. Pansipa pali njira yotsatirira mwatsatanetsatane njira iyi:
1. Kuphika Mafuta: Kusintha Kuchokera ku Mafuta Osaphwanyidwa Kukhala Mafuta Opaka Mafuta
Kuphika mafuta ndi njira yofunika kwambiri pakuyeretsa mafuta, makamaka pophwanya mafuta otsala ndi kutentha kwambiri kuti apange mpweya, mafuta a petulo, dizilo, mafuta osungunuka kwambiri, ndi mafuta a petulo. Cholinga chachikulu cha njirayi ndikusintha mafuta otsala olemera, otsika mtengo kukhala mafuta a petulo okhala ndi mtengo wapamwamba komanso zinthu zina zopepuka zamafuta.
Mitundu ya Njira: Njira zophikira mafuta zimaphatikizapo kufinya mochedwa, kufinya madzi, ndi kufinya mosinthasintha, pakati pa zina. Kufinya mochedwa ndi chipangizo chomwe chimagwiritsidwa ntchito kwambiri padziko lonse lapansi, pano "gawo" ndiloyenera kwambiri padziko lonse lapansi, pogwiritsa ntchito ng'oma ziwiri za coke zomwe zimagwira ntchito mosinthana. Mafuta otsala amasweka kutentha kwambiri, zomwe zimapangitsa coke yomwe imasonkhana m'ng'oma kenako imachotsedwa ndi kutsukidwa ndi hydraulic.
Makhalidwe a Zamalonda: Petroleum coke, chinthu chachikulu cholimba chomwe chimagwiritsidwa ntchito popanga coking, chimakhala ndi mpweya wambiri komanso kusasinthasintha kochepa. Kutengera ndi momwe imagwiritsidwira ntchito, petroleum coke ikhoza kugawidwa m'magulu amafuta kapena ma electrode. Petroleum coke imagwiritsidwa ntchito makamaka m'mafakitale monga kupanga magetsi ndi simenti, pomwe electrode-grade petroleum coke, chifukwa cha kuyera kwake komanso kuyendetsa bwino magetsi, imagwira ntchito ngati chinthu chofunikira kwambiri popanga ma electrode a graphite ndi zinthu za lithiamu-ion battery anode.
2. Kukonza Graphitization: Sublimation kuchokera ku Petroleum Coke kupita ku High-Purity Graphite Materials
Kukonza graphitization ndi gawo lofunika kwambiri pakusintha petroleum coke kukhala zinthu za graphite zoyera kwambiri. Njirayi nthawi zambiri imachitika kutentha kwambiri, komwe kutentha kumachepa komanso kusintha kwa graphitization kumayambitsa kusintha kwa kapangidwe ka petroleum coke, ndikupanga kapangidwe koyera ka graphite.
Njira Zopangira: Kukonza graphitization nthawi zambiri kumaphatikizapo njira monga kufufuza zinthu zopangira ndi kuphwanya, kuphika, ndi kukonza graphitization mu uvuni. Pa kutentha kwakukulu, zonyansa zotsalira mu petroleum coke zimatseka pang'onopang'ono, pomwe maatomu a kaboni amakonzedwanso kuti apange kapangidwe ka graphite kolimba. Pamapeto pake, pambuyo pokonza bwino ndikuyika, petroleum coke yomalizidwa yokhala ndi graphitized imakhala yokonzeka kugulitsidwa.
Makhalidwe a Zamalonda: Graphitized petroleum coke ili ndi chiyero chapamwamba, mphamvu zamagetsi zabwino kwambiri, komanso kukhazikika kwa kutentha kwambiri. Makhalidwe amenewa amachititsa kuti igwiritsidwe ntchito kwambiri popanga zinthu zosiyanasiyana zamafakitale, kuphatikizapo ma electrode, ma cathode, ndi mafuta a boiler. Makamaka m'magawo a mabatire a lithiamu-ion, graphitized petroleum coke, monga choyambira cha zipangizo za anode, imagwira ntchito yofunika kwambiri pakukweza kuchuluka kwa mphamvu ya batri, moyo wa kuzungulira, komanso chitetezo.
3. Kuchokera ku Graphitized Petroleum Coke kupita ku Mabatire a EV: Kuyendetsa Mphamvu Yobiriwira ya Tsogolo
Chifukwa cha kufunikira kwa mphamvu zoyera padziko lonse lapansi komanso chitukuko chokhazikika, magalimoto amagetsi awonekera ngati njira yofunika kwambiri yoyendetsera mtsogolo, zomwe zimapangitsa kuti luso ndi kupita patsogolo kwa ukadaulo wa mabatire zikhale zofunika kwambiri. Kugwiritsa ntchito coke ya petroleum yokhala ndi graphitized m'mabatire a EV kukuwonetsa izi.
Zinthu Zopangira Batire ya Anode: Graphitized petroleum coke idapangidwa kuti igwiritsidwe ntchito mbali ya anode ya mabatire a EV, imapereka liwiro lofulumira la kuchaja, mtunda wautali woyendetsera, komanso moyo wautali wa batire. Kuyera kwake kwakukulu komanso kuyendetsa bwino magetsi kumathandiza kusamutsa ma elekitironi bwino panthawi yochaja ndi kutulutsa batire, kuchepetsa kutayika kwa mphamvu ndikuwonjezera magwiridwe antchito a batire.
Chitsanzo cha Kugwiritsa Ntchito Zatsopano: Tengani ExxonMobil Corporation mwachitsanzo. Kampaniyo yapanga molekyulu yatsopano ya kaboni (yochokera pa ukadaulo wa petroleum coke) yomwe imatha kukulitsa moyo wa mabatire a EV ndi 30%. Kupangidwa kumeneku sikungowonjezera magwiridwe antchito ndi kudalirika kwa batri komanso kumachepetsa kudalira graphite yodulidwa, kupereka chithandizo champhamvu pakukula kokhazikika kwa magalimoto amagetsi.
Zochitika ndi Ziyembekezo za Msika: Pamene msika wa magetsi amagetsi ukupitirira kukula komanso ukadaulo wa mabatire ukupitilira patsogolo, mwayi wogwiritsa ntchito graphitized petroleum coke m'mabatire amagetsi ndi waukulu. Kumbali imodzi, ndi kusintha kwa kuchuluka kwa mphamvu yamagetsi amagetsi ndi kuchepetsa mtengo, kuchuluka kwa magalimoto amagetsi ndi kugwiritsa ntchito bwino ndalama kudzawonjezeka. Kumbali ina, kugwiritsa ntchito ukadaulo wochapira mwachangu komanso kukonza zomangamanga zochapira kudzathandiza kwambiri kugwiritsa ntchito magetsi amagetsi mosavuta. Zinthu izi pamodzi zidzayendetsa kukula kwa msika wa magetsi amagetsi, zomwe zidzawonjezera kufunikira kwa mafuta amagetsi amagetsi amagetsi.
