I-Needle coke inesakhiwo esifana nenaliti kwaye yenziwe ngeoyile ye-slurry evela kwiindawo zokucoca okanye i-coal tar pitch. Yeyona nto iphambili yokwenza ii-electrode ze-graphite ezisetyenziswa kwinkqubo yokuvelisa intsimbi kusetyenziswa i-electric arc furnace (EAF). Olu hlalutyo lwemarike ye-needle coke lujonga intengiso evela kushishino lwe-graphite, kushishino lwebhetri, nakwabanye. Uhlalutyo lwethu lujonga nentengiso ye-needle coke e-APAC, eYurophu, eMntla Melika, eMzantsi Melika, nakwi-MEA. Ngo-2018, icandelo loshishino lwe-graphite lalinesabelo esikhulu semarike, kwaye le ndlela kulindeleke ukuba iqhubeke kwixesha eliqikelelweyo. Izinto ezinje ngokufuna okunyukayo kwee-electrode ze-graphite kwindlela ye-EAF yokuvelisa intsimbi ziya kudlala indima ebalulekileyo kwicandelo loshishino lwe-graphite ukugcina indawo yalo kwimarike. Kwakhona, ingxelo yethu yemarike ye-needle coke yehlabathi ijonga izinto ezinje ngokunyuka kwamandla okucoca ioyile, ukunyuka kokwamkelwa kwezithuthi eziluhlaza, ukwanda kwemfuno yee-electrode ze-UHP graphite. Nangona kunjalo, imingeni ekhulayo yokungabikho kwemfuno ye-lithium kunye nobonelelo olujongene nokuzisa utyalo-mali kwishishini lamalahle ngenxa yemithetho echasene nongcoliseko lwekhabhoni, ukuguquguquka kwamaxabiso eoyile ekrwada kunye namalahle kunokuthintela ukukhula kweshishini le-needle coke kwixesha eliqikelelweyo.
IMarike yeCoke yeNeedle yeHlabathi: Isishwankathelo
Imfuno ekhulayo yee-electrodes ze-graphite ze-UHP
Ii-electrode zegraphite zisetyenziswa kwizicelo, ezifana nezitofu ze-arc ezingaphantsi komhlaba kunye nezitofu zeladle zokuvelisa intsimbi, izinto ezingezizo zesinyithi, kunye neentsimbi. Zikwasetyenziswa kakhulu kwi-EAFs kwimveliso yentsimbi. Ii-electrode zegraphite zinokuveliswa kusetyenziswa i-petroleum coke okanye i-needle coke. Ii-electrode zegraphite zahlulwe zibe ngamandla aqhelekileyo, amandla aphezulu, amandla aphezulu kakhulu, kunye ne-UHP ngokusekelwe kwiiparameter ezifana nokumelana, ukuqhuba kombane, ukuqhuba kobushushu, ukumelana ne-oxidation kunye nokutshayiswa kobushushu, kunye namandla oomatshini. Kuzo zonke iintlobo zee-electrode zegraphite. Ii-electrode zegraphite ze-UHP ziyafumana ingqalelo kwishishini lentsimbi. Le mfuno yee-electrode ze-UHP iya kukhokelela ekwandeni kwemarike ye-needle coke yehlabathi kwi-CAGR ye-6% ngexesha lexesha eliqikelelweyo.
Ukuvela kwentsimbi eluhlaza
Ukukhutshwa kwe-CO2 yingxaki enkulu ejongene nomzi-mveliso wentsimbi kwihlabathi liphela. Ukusombulula le ngxaki, kwenziwe imisebenzi emininzi yophando nophuhliso (R&D). Le misebenzi yophando nophuhliso ikhokelele ekuveleni kwentsimbi eluhlaza. Abaphandi bafumene inkqubo entsha yokwenza intsimbi enokuphelisa ukukhutshwa kwe-CO2 ngokupheleleyo. Kwinkqubo yesiqhelo yokwenza intsimbi, ngexesha lokuveliswa kwentsimbi, kukhutshwa umsi omninzi, ikhabhoni, kunye nelangatye elivuthayo. Inkqubo yesiqhelo yokwenza intsimbi ikhupha i-CO2 kabini kunobunzima bentsimbi. Nangona kunjalo, le nkqubo intsha inokuphumeza ukwenziwa kwentsimbi ngaphandle kokukhutshwa kwegesi. Itekhnoloji yokujova amalahle acoliweyo kunye nokubamba nokugcina ikhabhoni (CCS) iphakathi kwazo. Olu phuhliso kulindeleke ukuba lube nefuthe elihle ekukhuleni kwemarike iyonke.
Indawo yoKhuphiswano
Ngenxa yokuba kukho abadlali abambalwa abaphambili, imakethi yehlabathi ye-needle coke igxile kakhulu. Olu hlalutyo oluqinileyo lwabathengisi lwenzelwe ukunceda abathengi baphucule isikhundla sabo kwimakethi, kwaye ngokuhambelana noku, le ngxelo inika uhlalutyo oluneenkcukacha lwabavelisi abaninzi abaphambili be-needle coke, abaquka i-C-Chem Co. Ltd., i-GrafTech International Ltd., i-Mitsubishi Chemical Holdings Corp., i-Phillips 66 Co., i-Sojitz Corp., kunye ne-Sumitomo Corp.
Kwakhona, ingxelo yohlalutyo lwemarike ye-needle coke ibandakanya ulwazi malunga neendlela ezizayo kunye nemingeni eya kuba nefuthe ekukhuleni kwemarike. Oku kwenzelwa ukunceda iinkampani ukuba zicwangcise kwaye zisebenzise onke amathuba okukhula azayo.
