Ma ke ʻano he kumuwaiwai hou ʻole, he ʻokoʻa nā ʻano kuhikuhi o ka ʻaila ma muli o kahi i puka mai ai. Eia nō naʻe, i ka hoʻoholo ʻana mai nā waihona i hōʻoia ʻia a me ka hoʻolaha ʻana o ka ʻaila maka honua, ʻo ka nui o ka ʻaila maka māmā he 39 biliona tone, ʻoi aku ka liʻiliʻi ma mua o ka nui o ka ʻaila maka māmā sulfur kiʻekiʻe, ka ʻaila maka waena a me ka ʻaila maka kaumaha. ʻO nā wahi hana nui o ka honua ʻo ʻApelika Komohana wale nō, Brazil, ke Kai ʻĀkau, ke Kaiwaenahonua, ʻAmelika ʻĀkau, ka Hikina Loa a me nā wahi ʻē aʻe. Ma ke ʻano he huahana o ke kaʻina hana hoʻomaʻemaʻe kuʻuna, pili loa ka hana ʻana o ka petroleum coke a me nā hōʻailona i nā hōʻailona ʻaila maka. Ma muli o kēia, mai ka manaʻo o ka hoʻonohonoho ʻana o ka petroleum coke honua, ʻoi aku ka haʻahaʻa o ka hapa o ka low-sulfur petroleum coke ma mua o ka medium a me high-sulfur petroleum coke.
Mai ka manaʻo o ka hoʻolaha ʻana o nā ʻōkuhi petroleum coke o Kina, ʻo ka hana ʻana o ka low-sulfur petroleum coke (petroleum coke me ka nui o ka sulfur ma lalo o 1.0%) he 14% o ka huina o ka hana petroleum coke aupuni. He 5% ia o ka huina o ka petroleum coke i lawe ʻia mai ma Kina. E nānā kākou i ka lako o ka low-sulfur petroleum coke ma Kina i nā makahiki ʻelua i hala.
Wahi a ka ʻikepili mai nā makahiki ʻelua i hala iho nei, ʻo ka hana mahina o ka low-sulfur petroleum coke ma nā hale hana hoʻomaʻemaʻe kūloko ua noho mau ma kahi o 300,000 tons, a ua loli iki ka lako o ka low-sulfur petroleum coke i lawe ʻia mai, a hiki i kona kiʻekiʻe loa i Nowemapa 2021. Eia nō naʻe, aia kekahi mau hihia kahi i ʻole ai ka nui o ka lawe ʻana mai o ka low-sulfur petroleum coke i kēlā me kēia mahina. Ma ka hoʻoholo ʻana mai ka lako o ka low-sulfur petroleum coke ma Kina i nā makahiki ʻelua i hala iho nei, ua noho mau ka lako mahina ma kahi kiʻekiʻe o kahi o 400,000 tons mai ʻAukake o kēia makahiki.
Mai ka manaʻo o ke koi a Kina no ka low-sulfur petroleum coke, hoʻohana nui ʻia ia i ka hana ʻana o nā electrodes graphite, nā mea anode graphite artificial, nā cathodes graphite a me nā anodes prebaked. ʻO ke koi no ka low-sulfur petroleum coke ma nā kahua mua ʻekolu he koi paʻa, a ʻo ke koi no ka low-sulfur petroleum coke ma ke kahua o nā anodes prebaked e hoʻohana nui ʻia no ka hoʻolaha ʻana i nā ʻōkuhi, ʻoiai ka hana ʻana o nā anodes prebaked kiʻekiʻe me nā koi kiʻekiʻe no ka ʻike sulfur a me nā mea trace. Mai ka hoʻomaka ʻana o kēia makahiki, me ka hoʻonui ʻana o ke kumu o ka petroleum coke i lawe ʻia mai, ua hōʻea mai nā kumuwaiwai hou aʻe me nā mea trace maikaʻi aʻe i Hong Kong. No ke kahua o nā anodes prebaked, ua hoʻonui ʻia ke koho ʻana o nā mea maka, a ua emi pū kona hilinaʻi ʻana i ka low-sulfur petroleum coke. Eia kekahi, i ka hapa lua o kēia makahiki, ua hāʻule ka helu hana o ke kahua electrode graphite kūloko i lalo o 30%, e hāʻule ana i kahi kiko hau mōʻaukala. No laila, mai ka hapaha ʻehā, ua hoʻonui ʻia ka lako o ka low-sulfur petroleum coke kūloko a ua emi ke koi, a ua alakaʻi i ka emi ʻana o ke kumukūʻai o ka low-sulfur petroleum coke kūloko.
Ma muli o ke ʻano o ka loli ʻana o ke kumukūʻai o kahi hale hana hoʻomaʻemaʻe CNOOC i nā makahiki ʻelua i hala iho nei, ua hoʻomaka ke kumukūʻai o ka low-sulfur petroleum coke e loli mai kahi kiʻekiʻe mai ka hapa lua o ka makahiki. Eia naʻe, i kēia manawa, ua hōʻike mālie ka mākeke i nā hōʻailona o ka paʻa ʻana, no ka mea, ʻo ke koi no ka low-sulfur petroleum coke ma ke kahua o nā anodes i hoʻomoʻa mua ʻia he wahi elastic nui. Ua hoʻi mālie mai ka ʻokoʻa kumukūʻai ma waena o ka low-sulfur petroleum coke a me ka medium-sulfur petroleum coke.
No ke koi o kēia manawa ma ke kahua o lalo o ka coke petroleum kūloko, me ka lohi o ke koi no nā electrodes graphite, ke kiʻekiʻe nei ke koi no nā mea anode graphite artificial, nā cathodes graphite a me nā anodes prebaked, a ʻo ke koi paʻa no ka coke petroleum sulfur waena a me ka haʻahaʻa ke ikaika nei. Ma ke ʻano holoʻokoʻa, i ka wā pōkole, nui nā kumuwaiwai coke low-sulfur kūloko, a nāwaliwali ke kākoʻo kumukūʻai, akā ikaika nō ka coke petroleum medium-sulfur, kahi e pāʻani pū ana i kahi kuleana kākoʻo i ka mākeke coke petroleum low-sulfur.
