Njengomthombo ongavuseleleki, uwoyela unezimpawu zenkomba ezihlukene kuye ngendawo umsuka wayo. Kodwa-ke, uma sibheka izindawo ezigciniwe eziqinisekisiwe kanye nokusatshalaliswa kukawoyela ongahluziwe emhlabeni wonke, izinqolobane zikawoyela ongahluziwe ongahluziwe ongatheni zingamathani ayizigidi eziyizinkulungwane ezingama-39, okungaphansi kwemithombo kawoyela ongahluziwe wesulfure, uwoyela ongahluziwe ophakathi nendawo kanye nowoyela ongahluziwe osindayo. Izindawo ezikhiqiza kakhulu zomhlaba yiNtshonalanga Afrika kuphela, iBrazil, iNorth Sea, iMedithera, iNyakatho Melika, iMpumalanga Ekude nezinye izindawo. Njengomkhiqizo wenqubo yokucwenga yendabuko, ukukhiqizwa kwe-petroleum coke kanye nezinkomba kuhlobene eduze nezinkomba zikawoyela ongahluziwe. Ethintwe yilokhu, ngokombono we-global petroleum coke index structure, ingxenye ye-low-sulfur petroleum coke iphansi kakhulu kune-medium and high-sulfur petroleum coke.
Ngokombono wokusatshalaliswa kwesakhiwo sezinkomba ze-petroleum coke yaseShayina, ukukhiqizwa kwe-coke ye-petroleum ye-petroleum ephansi (i-petroleum coke enesulfure engaphansi kuka-1.0%) yenza u-14% wesamba sengqikithi ye-coke ye-petroleum kazwelonke. Ibalelwa ku-5% yenani eliphelele le-petroleum coke engenisiwe e-China. Ake sibheke ukuhlinzekwa kwe-coke ye-low-sulfur petroleum coke e-China eminyakeni emibili edlule.
Ngokwemininingwane yeminyaka emibili edlule, ukukhishwa kwanyanga zonke kwe-low-sulfur petroleum coke ezindaweni zokuhluza ezifuywayo kuhlale cishe kumathani angama-300,000, kanti ukuhlinzekwa kwe-coke ye-low-sulfur petroleum coke iye yashintshashintsha, yafinyelela inani eliphakeme ngoNovemba 2021. Nokho, kukhona futhi izimo lapho umthamo wanyanga zonke wokungenisa we-low-sulphur petroleum coke unguziro. Uma sibheka ukuhlinzekwa kwe-coke ye-low-sulfur petroleum coke e-China eminyakeni emibili edlule, ukunikezwa kwanyanga zonke kuhlezi kusezingeni eliphezulu cishe amathani angu-400,000 kusukela ngo-August kulo nyaka.
Ngokombono wesidingo saseShayina se-low-sulfur petroleum coke, isetshenziswa kakhulu ekukhiqizeni ama-electrode e-graphite, izinto zokwenziwa ze-graphite anode, ama-graphite cathode nama-anode abhakwe ngaphambilini. Isidingo se-coke ye-petroleum ephansi yesulfure emikhakheni emithathu yokuqala siyisidingo esiqinile, futhi isidingo se-coke ye-petroleum ephansi yesulfure emkhakheni we-anode ephekiwe isetshenziselwa ikakhulukazi ukuthunyelwa kwezinkomba, ikakhulukazi ukukhiqizwa kwama-anode aphethwe ngaphambili. enezidingo eziphezulu zokuqukethwe kwesibabule kanye nezakhi zokulandelela . Kusukela ekuqaleni kwalo nyaka, ngokwanda komthombo we-petroleum coke evela kwamanye amazwe, izinsiza ezengeziwe ezinezici zokulandelela ezingcono sezifikile eHong Kong. Emkhakheni wama-anode aphekiwe, ukukhethwa kwezinto zokusetshenziswa kuye kwanda, futhi ukuncika kwayo ku-coke ye-petroleum ephansi yesulfure kuye kwehlile. . Ngaphezu kwalokho, engxenyeni yesibili yalo nyaka, izinga lokusebenza lensimu ye-graphite electrode yasekhaya lehlile laya ngaphansi kwama-30%, liwela endaweni yokuqandisa yomlando. Ngakho-ke, kusukela ngekota yesine, ukuhlinzekwa kwe-coke ye-petroleum coke yasekhaya enesulfure ephansi kuye kwanda futhi isidingo sehlile, okuholele ekwehleni kwentengo ye-coke yasekhaya ene-sulphur petroleum coke.
Uma sibheka izitayela zokushintsha intengo yendawo yokuhluza i-CNOOC eminyakeni emibili edlule, intengo ye-low-sulfur petroleum coke isiqalile ukuguquguquka ukusuka ezingeni eliphezulu kusukela engxenyeni yesibili yonyaka. Kodwa-ke, muva nje, imakethe ibonise kancane kancane izimpawu zokuzinza, ngoba isidingo se-coke ye-petroleum ephansi yesulfure emkhakheni we-anode ephekiwe inendawo enkulu yokunwebeka. Umehluko wamanani phakathi kwe-low-sulphur petroleum coke ne-medium-sulphur petroleum coke kancane kancane wabuya.
Ngokuqondene nesidingo samanje emkhakheni ongezansi womfula we-coke ye-petroleum yasekhaya, ngaphezu kwesidingo esivilaphayo sama-graphite electrode, isidingo sezinto zokwenziwa ze-graphite anode, ama-graphite cathodes nama-anode aphekiwe kusephezulu, kanye nesidingo esiqinile sezinto ezimaphakathi. kanye ne-low sulfur petroleum coke isenamandla uma kuqhathaniswa. Sekukonke, esikhathini esifushane, izinsiza ze-coke ezifuywayo ezinesulfure ephansi ziningi uma kuqhathaniswa, futhi ukwesekwa kwentengo akunamandla, kodwa i-medium-sulfur petroleum coke isenamandla, nayo edlala indima ethile yokusekela endaweni ephansi- imakethe ye-sulphur petroleum coke.
