I-Needle coke inesakhiwo esifana nenaliti futhi yenziwe ngamafutha e-slurry avela ezindaweni zokuhlanza noma i-coal tar pitch. Yiyona nto eyinhloko yokwenza ama-electrode e-graphite asetshenziswa enkambisweni yokukhiqiza insimbi kusetshenziswa i-electric arc furnace (EAF). Lokhu kuhlaziywa kwemakethe ye-needle coke kubheka ukuthengiswa okuvela embonini ye-graphite, imboni yebhethri, nabanye. Ukuhlaziywa kwethu kubheka nokuthengiswa kwe-needle coke e-APAC, eYurophu, eNyakatho Melika, eNingizimu Melika, kanye nase-MEA. Ngo-2018, ingxenye yemboni ye-graphite yayinesabelo esikhulu semakethe, futhi lo mkhuba kulindeleke ukuthi uqhubeke phakathi nesikhathi sokubikezela. Izici ezifana nesidingo esikhulayo sama-electrode e-graphite sendlela ye-EAF yokukhiqiza insimbi zizodlala indima ebalulekile esigabeni semboni ye-graphite ukuze zigcine isikhundla sayo semakethe. Futhi, umbiko wethu wemakethe ye-needle coke yomhlaba wonke ubheka izici ezifana nokwanda kwamandla okucwenga uwoyela, ukwanda kokwamukelwa kwezimoto eziluhlaza, ukwanda kwesidingo sama-electrode e-UHP graphite. Kodwa-ke, izinselelo ezikhulayo zegebe lokufunwa kwe-lithium kanye nokuhlinzekwa kwempahla ezibhekene nokuletha ukutshalwa kwezimali embonini yamalahle ngenxa yemithetho emelene nokungcoliswa kwekhabhoni, ukuguquguquka kwamanani kawoyela ongahluziwe kanye namalahle kungaphazamisa ukukhula kwemboni ye-needle coke esikhathini esibikezelwe.
Imakethe Yomhlaba Wonke Ye-Needle Coke: Ukubuka Konke
Isidingo esikhulayo sama-electrode e-graphite e-UHP
Ama-electrode e-graphite asetshenziswa ezinhlotsheni, njengezitofu ze-arc ezingaphansi kwamanzi kanye nezitofu ze-ladle zokukhiqiza insimbi, izinto ezingezona ezensimbi, kanye nezinsimbi. Asetshenziswa futhi ikakhulukazi kuma-EAF ekukhiqizeni insimbi. Ama-electrode e-graphite angakhiqizwa kusetshenziswa i-petroleum coke noma i-needle coke. Ama-electrode e-graphite ahlukaniswa ngamandla ajwayelekile, amandla aphezulu, amandla aphezulu kakhulu, kanye ne-UHP ngokusekelwe kumapharamitha afana nokumelana, ukuqhuba kukagesi, ukuqhuba kokushisa, ukumelana ne-oxidation kanye nokushaqeka kokushisa, kanye namandla omshini. Kuzo zonke izinhlobo zama-electrode e-graphite. Ama-electrode e-graphite e-UHP athola ukunakwa embonini yensimbi. Lesi sidingo sama-electrode e-UHP sizoholela ekwandiseni imakethe yomhlaba wonke ye-needle coke ku-CAGR engu-6% ngesikhathi sokubikezela.
Ukuvela kwensimbi eluhlaza
Ukukhishwa kwe-CO2 kuyinkinga enkulu ebhekene nemboni yensimbi emhlabeni jikelele. Ukuze kuxazululwe le nkinga, kuye kwenziwa imisebenzi eminingi yocwaningo nentuthuko (R&D). Le misebenzi ye-R&D iholele ekuveleni kwensimbi eluhlaza. Abacwaningi bathole inqubo entsha yokwenza insimbi engaqeda ngokuphelele ukukhishwa kwe-CO2. Enkambisweni yendabuko yokwenza insimbi, ngesikhathi sokukhiqizwa kwensimbi, kukhishwa inani elikhulu lentuthu, ikhabhoni, kanye nelangabi elivuthayo. Inqubo yendabuko yokwenza insimbi ikhipha i-CO2 kabili kunesisindo sensimbi. Kodwa-ke, inqubo entsha ingafeza ukwenza insimbi ngaphandle kokukhishwa kwegesi. Ubuchwepheshe bokufaka amalahle acoliwe kanye nokubamba nokugcina ikhabhoni (CCS) buphakathi kwabo. Lokhu kuthuthukiswa kulindeleke ukuthi kube nomthelela omuhle ekukhuleni kwemakethe iyonke.
Indawo Yokuncintisana
Njengoba kukhona abadlali abambalwa ababalulekile, imakethe yomhlaba wonke ye-needle coke igxile kakhulu. Lokhu kuhlaziywa okunamandla kwabathengisi kuklanyelwe ukusiza amakhasimende ukuthuthukisa isikhundla sabo semakethe, futhi ngokuhambisana nalokhu, lo mbiko unikeza ukuhlaziywa okuningiliziwe kwabakhiqizi abaningana abaphambili be-needle coke, abahlanganisa i-C-Chem Co. Ltd., i-GrafTech International Ltd., i-Mitsubishi Chemical Holdings Corp., i-Phillips 66 Co., i-Sojitz Corp., kanye ne-Sumitomo Corp.
Futhi, umbiko wokuhlaziywa kwemakethe ye-needle coke uhlanganisa ulwazi mayelana nezitayela nezinselele ezizayo ezizothinta ukukhula kwemakethe. Lokhu kwenzelwa ukusiza izinkampani ukuthi zihlele amasu futhi zisebenzise wonke amathuba okukhula azayo.
