Needle coke ili ndi kapangidwe kofanana ndi singano ndipo imapangidwa ndi mafuta osungunuka ochokera ku mafakitale oyeretsera kapena phula la malasha. Ndi chinthu chachikulu chopangira ma electrode a graphite omwe amagwiritsidwa ntchito popanga chitsulo pogwiritsa ntchito ng'anjo yamagetsi ya arc (EAF). Kusanthula kwa msika wa needle coke uku kumaganizira zogulitsa kuchokera kumakampani opanga ma graphite, makampani opanga mabatire, ndi ena. Kusanthula kwathu kumaganiziranso zogulitsa za needle coke ku APAC, Europe, North America, South America, ndi MEA. Mu 2018, gawo la makampani opanga ma graphite linali ndi gawo lalikulu pamsika, ndipo izi zikuyembekezeka kupitilira panthawi yolosera. Zinthu monga kukwera kwa kufunikira kwa ma electrode a graphite panjira ya EAF yopanga zitsulo zidzakhala ndi gawo lofunikira mu gawo la makampani opanga ma graphite kuti asunge malo ake pamsika. Komanso, lipoti lathu la msika wapadziko lonse wa needle coke likuyang'ana zinthu monga kuwonjezeka kwa mphamvu yoyeretsera mafuta, kukwera kwa kugwiritsa ntchito magalimoto obiriwira, kukwera kwa kufunikira kwa ma electrode a UHP graphite. Komabe, mavuto omwe akukumana nawo pakukulitsa kusiyana kwa kufunika kwa lithiamu ndi kupereka zinthu m'makampani opanga malasha chifukwa cha malamulo oletsa kuipitsa mpweya wa carbon, kusinthasintha kwa mitengo ya mafuta osakonzedwa ndi malasha kungalepheretse kukula kwa makampani opanga needle coke panthawi yomwe yanenedweratu.
Msika Wadziko Lonse wa Needle Coke: Chidule
Kufunika kwakukulu kwa ma electrode a graphite a UHP
Ma electrode a graphite amagwiritsidwa ntchito pazinthu monga ma arc ng'anjo olowa pansi ndi ma ladle ng'anjo zopangira chitsulo, zinthu zopanda chitsulo, ndi zitsulo. Amagwiritsidwanso ntchito makamaka mu EAFs popanga chitsulo. Ma electrode a graphite amatha kupangidwa pogwiritsa ntchito petroleum coke kapena needle coke. Ma electrode a graphite amagawidwa m'magulu a mphamvu yokhazikika, mphamvu yayikulu, mphamvu yayikulu kwambiri, ndi UHP kutengera magawo monga resistivity, electric conductivity, thermal conductivity, resistance to oxidation and thermal shock, komanso mphamvu yamakina. Mwa mitundu yonse ya ma electrode a graphite, ma electrode a graphite a UHP akutchuka kwambiri mumakampani achitsulo. Kufunika kumeneku kwa ma electrode a UHP kudzatsogolera kukukula kwa msika wapadziko lonse wa needle coke pa CAGR ya 6% panthawi yolosera.
Kutuluka kwa chitsulo chobiriwira
Kutulutsa mpweya wa CO2 ndi vuto lalikulu lomwe makampani opanga zitsulo padziko lonse lapansi akukumana nalo. Pofuna kuthetsa vutoli, kafukufuku ndi chitukuko cha zinthu zambiri (R&D) chachitika. Ntchito za R&D izi zapangitsa kuti chitsulo chobiriwira chiwonekere. Ofufuza apeza njira yatsopano yopangira zitsulo yomwe ingachotse mpweya wa CO2 kwathunthu. Mu njira yachikhalidwe yopangira zitsulo, popanga zitsulo, utsi wambiri, kaboni, ndi lawi loyaka moto zimatulutsidwa. Njira yachikhalidwe yopangira zitsulo imatulutsa CO2 kawiri kuposa kulemera kwa chitsulo. Komabe, njira yatsopanoyi ikhoza kupanga zitsulo popanda kutulutsa mpweya uliwonse. Ukadaulo wothira malasha ndi ukadaulo wosunga ndi kusunga mpweya wa kaboni (CCS) ndi zina mwa izo. Kukula kumeneku kukuyembekezeka kukhala ndi zotsatira zabwino pakukula kwa msika wonse.
Malo Opikisana
Popeza pali osewera ochepa akuluakulu, msika wapadziko lonse wa needle coke ndi wotanganidwa kwambiri. Kusanthula kwamphamvu kwa ogulitsa kumeneku kwapangidwa kuti kuthandize makasitomala kukonza malo awo pamsika, ndipo mogwirizana ndi izi, lipotili limapereka kusanthula kwatsatanetsatane kwa opanga angapo otsogola a needle coke, omwe akuphatikizapo C-Chem Co. Ltd., GrafTech International Ltd., Mitsubishi Chemical Holdings Corp., Phillips 66 Co., Sojitz Corp., ndi Sumitomo Corp.
Komanso, lipoti lofufuza msika wa needle coke lili ndi chidziwitso cha zomwe zikuchitika komanso zovuta zomwe zikubwera zomwe zidzakhudza kukula kwa msika. Izi zikuthandizira makampani kupanga mapulani ndikugwiritsa ntchito mwayi wonse wokulira womwe ukubwera.
