Monga gwero losasinthika, mafuta ali ndi mawonekedwe osiyanasiyana malinga ndi komwe amachokera. Komabe, kutengera nkhokwe zomwe zatsimikizidwa komanso kugawa kwamafuta amafuta padziko lonse lapansi, nkhokwe zamafuta otsekemera otsekemera ndi pafupifupi matani 39 biliyoni, omwe ndi ocheperako poyerekeza ndi nkhokwe zamafuta opepuka a sulfure, mafuta apakati komanso mafuta osapsa kwambiri. Madera omwe amapanga kwambiri padziko lapansi ndi West Africa, Brazil, North Sea, Mediterranean, North America, Far East ndi malo ena. Monga chotulukapo cha njira yoyenga yachikhalidwe, kupanga mafuta a petroleum coke ndi zizindikiro zimagwirizana kwambiri ndi zizindikiro zamafuta osakhazikika. Kukhudzidwa ndi izi, malinga ndi ndondomeko ya ndondomeko ya mafuta a petroleum coke padziko lonse, gawo la mafuta otsika a sulfure a petroleum coke ndi lochepa kwambiri kusiyana ndi lapakati ndi lapamwamba la sulfure petroleum coke.
Malinga ndi kagayidwe kagawo ka zizindikiro za mafuta aku China, kutulutsa kwa mafuta a sulfure otsika (petroleum coke yokhala ndi sulfure zosakwana 1.0%) kumapanga 14% yamafuta onse adziko lonse lapansi. Imawerengera pafupifupi 5% yamafuta onse omwe amatumizidwa kunja ku China. Tiyeni tiwone za kupezeka kwa mafuta a sulfure otsika ku China pazaka ziwiri zapitazi.
Malinga ndi zomwe zachitika zaka ziwiri zapitazi, kutulutsa kwamafuta amafuta otsika sulfure pamwezi m'malo oyenga m'nyumba kumakhalabe pafupifupi matani 300,000, ndipo kupezeka kwa mafuta otsika a sulfure otsika kwatsika, kufika pachimake mu Novembala 2021. Komabe, palinso nthawi zina pomwe kuchuluka kwa mafuta a petroleum coke otsika mwezi uliwonse ndi ziro. Potengera kupezeka kwa mafuta otsika a sulfure ku China m'zaka ziwiri zapitazi, kupezeka kwamafuta pamwezi kwakhalabe kwakukulu pafupifupi matani 400,000 kuyambira Ogasiti chaka chino.
Malinga ndi zomwe dziko la China likufuna kuti mafuta a sulfure otsika, amagwiritsidwa ntchito kwambiri popanga ma elekitirodi a graphite, zida zopangira ma graphite anode, ma graphite cathodes ndi anode ophika kale. Kufunika otsika sulfure petroleum coke m'minda atatu okhwima kufunika, ndi kufunika otsika sulfure mafuta coke m'munda wa anodes prebaked makamaka ntchito kutumizidwa kwa zizindikiro, makamaka kupanga mkulu-mapeto prebaked anodes. ndi zofunika kwambiri za sulfure ndi kufufuza zinthu . Kuyambira kuchiyambi kwa chaka chino, ndi kuwonjezeka kwa gwero la mafuta a petroleum coke, chuma chowonjezereka chokhala ndi ma trace elements abwino chafika ku Hong Kong. Pamunda wa anode ophikidwa kale, kusankha kwa zinthu zopangira kwachulukira, ndipo kudalira kwake pamafuta otsika a sulfure kwatsikanso. . Kuonjezera apo, mu theka lachiwiri la chaka chino, ntchito yogwiritsira ntchito malo opangira ma elekitirodi a graphite watsika mpaka pansi pa 30%, kugwera kumalo oundana a mbiri yakale. Chifukwa chake, kuyambira kotala lachinayi, kupezeka kwa petroleum coke yapanyumba yotsika kwambiri ya sulfure yakhala ikuchulukirachulukira ndipo kufunikira kwatsika, zomwe zapangitsa kutsika kwa mtengo wamafuta am'nyumba otsika sulfure petroleum coke.
Potengera kusintha kwa mtengo wa makina oyeretsera a CNOOC m'zaka ziwiri zapitazi, mtengo wa mafuta a sulfure otsika wayamba kusinthasintha kuchokera pamlingo wapamwamba kuyambira theka lachiwiri la chaka. Komabe, posachedwapa, msika wawonetsa pang'onopang'ono zizindikiro za kukhazikika, chifukwa kufunikira kwa mafuta otsika a sulfure coke m'munda wa anode ophika kale ali ndi malo ochuluka kwambiri. Kusiyana kwamitengo pakati pa low-sulfur petroleum coke ndi medium-sulphur petroleum coke pang'onopang'ono kunabwerera.
Monga momwe kufunikira kwapano m'munda wakumunsi wamafuta amafuta am'nyumba, kuwonjezera pakufunidwa kwaulesi kwa ma elekitirodi a graphite, kufunikira kwa zida zopangira ma graphite anode, ma graphite cathodes ndi anode ophika akadali okwera, komanso kufunikira kolimba kwa sing'anga. ndipo mafuta otsika a sulfur petroleum coke akadali amphamvu. Pazonse, m'kanthawi kochepa, zinthu zonse zapakhomo zokhala ndi sulfure wa sulfure ndizochuluka, ndipo chithandizo chamtengo wapatali ndi chofooka, koma petroleum coke yapakati-sulfure idakali yamphamvu, yomwe imagwiranso ntchito ina yothandiza kutsika. msika wa sulfure petroleum coke.
