[Needle Coke] Hāʻawi a noi i ka nānā ʻana a me ka hoʻomohala ʻana i nā hiʻohiʻona o ka coke needle ma Kina
I. Ka hiki makeke kokeke ko Kina
I ka makahiki 2016, he 1.07 miliona tons/makahiki ka nui o ka hana o ke kola coke honua, a he 350,000 tons/makahiki ka nui o ka hana o Kina, he 32.71% o ka mana hana honua. I ka makahiki 2021, ua hoʻonui ʻia ka nui o ka hana o ka coke coke honua i 3.36 miliona tons / makahiki, ma waena o ka nui o ka hana ʻana o Kina i ka coke needle he 2.29 miliona tons / makahiki, e helu ana no 68.15% o ka mana hana honua. Ua hoʻonui ʻia nā ʻoihana hana o Kina i ka 22. Ua hoʻonui ʻia ka nui o ka nui o ka hana o nā ʻoihana coke koki kūloko ma 554.29% i hoʻohālikelike ʻia me 2016, ʻoiai ua paʻa ka mana hana o nā coke nila haole. Ma ka makahiki 2022, ua hoʻonui ʻia ka nui o ka hana ʻana o Kina i ka 2.72 miliona tons, kahi ma kahi o 7.7 mau manawa, a ua hoʻonui ʻia ka helu o nā mea hana coke Kina i 27, e hōʻike ana i ka ulu nui o ka ʻoihana, a me ka nānā ʻana i ka honua. , ke piʻi aʻe nei ka nui o ka coke needle o Kina i ka mākeke honua i kēlā me kēia makahiki.
1. Aila hana mana o ka nila coke
Ua hoʻomaka ka ulu ʻana o ka hiki o ka aila-series needle coke mai 2019. Mai 2017 a 2019, ua hoʻomalu ʻia ka mākeke o ka aila-series needle coke e nā ana lanahu, ʻoiai ua lohi ka hoʻomohala ʻana o ka aila-series needle coke. ʻO ka hapa nui o nā ʻoihana i hoʻokumu ʻia i hoʻokumu ʻia ma hope o 2018, a ʻo ka nui o ka hana ʻana o ka aila-series needle coke ma Kina i hōʻea i 1.59 miliona tons e 2022. Ua hoʻonui mau ka hana i kēlā me kēia makahiki. I ka makahiki 2019, ua huli nui ka mākeke graphite electrode i lalo, a ua nāwaliwali ke koi no ka coke needle. I ka makahiki 2022, ma muli o ka hopena o ka maʻi maʻi COVID-19 a me ka 'Olumepika Hoʻoilo a me nā hanana lehulehu ʻē aʻe, ua nāwaliwali ka noi, ʻoiai ke kiʻekiʻe nā kumukūʻai, ʻoi aku ka liʻiliʻi o nā ʻoihana e hana, a lohi ka ulu ʻana.
2. Iecaianoaaiiuo hiki o ka lanahu ana needle coke
Ke hoʻomau nei ka hoʻonui ʻana i ka hiki o ka lanahu coke ana i kēlā me kēia makahiki, mai 350,000 tons i 2017 a i 1.2 miliona tons i 2022. Mai 2020, emi ka mākeke o ke ana lanahu, a lilo ka aila moʻo nila coke i ka mainstream o ka nila coke. Ma keʻano o ka hoʻopukaʻana, ua mālamaʻo ia i ka uluʻana mai ka 2017 a hiki i ka 2019. Mai ka 2020, ma kekahiʻaoʻao, ua kiʻekiʻe ke kumukūʻai a ua hoʻohuliʻia ka waiwai. Ma ka ʻaoʻao ʻē aʻe, ʻaʻole maikaʻi ka noi no ka electrode graphite.
Ⅱ. Ka noiʻi ʻana i ka nila Coke ma Kina
1. Ke kālailai mākeke o nā mea lithium anode
Mai ka hoʻopuka waiwai maikaʻi ʻole, ua hoʻonui mau ʻia ka puka makahiki o nā mea maikaʻi ʻole o Kina mai 2017 a 2019. I ka makahiki 2020, i hoʻopilikia ʻia e ka piʻi mau ʻana o ka mākeke terminal downstream, hoʻomaka ka hoʻomaka holoʻokoʻa o ka pā uila mana, piʻi nui ka mākeke. , a piʻi aʻe nā kauoha o nā ʻoihana waiwai electrode maikaʻi ʻole, a piʻi koke ka hoʻomaka holoʻokoʻa o ka ʻoihana a mālama i ka piʻi i luna. I ka makahiki 2021-2022, ua hōʻike ʻia ka ulu ʻana o ka lithium cathode i Kina, e pōmaikaʻi ana i ka hoʻomaikaʻi mau ʻana o ka ʻoihana ʻoihana o nā ʻoihana o lalo, ka ulu wikiwiki ʻana o ka mākeke kaʻa kaʻa hou, ka mālama ʻana i ka ikehu, ka ʻai, ka mana liʻiliʻi a me nā mākeke ʻē aʻe. nā degere o ka ulu ʻana, a mālama ʻia nā ʻoihana waiwai cathode nui i ka hana piha. Ua manaʻo ʻia ʻo ka hoʻopuka ʻana o nā mea electrode maikaʻi ʻole e manaʻo ʻia e ʻoi aku ma mua o 1.1 miliona tons i ka makahiki 2022, a aia ka huahana i kahi kūlana pōkole, a ākea ka noi o nā mea electrode maikaʻi ʻole.
ʻO Needle coke ka ʻoihana upstream o ka pā lithium a me nā mea anode, kahi pili pili i ka hoʻomohala ʻana o ka pākaukau lithium a me ka mākeke mea cathode. ʻO nā papa noi o ka pākaukau lithium ka mea nui e pili ana i ka pā uila, nā mea kūʻai aku a me ka pākaukau mālama ikehu. I ka makahiki 2021, e helu ʻia nā pihi mana no ka 68%, nā pākahi mea kūʻai aku no ka 22%, a me nā ʻeke hoʻopaʻa ikehu no 10% o ka hoʻolālā huahana pākaukau lithium ion o Kina.
ʻO ka pā uila ka mea nui o nā kaʻa ikehu hou. I nā makahiki i hala iho nei, me ka hoʻokō ʻana i ke kulekele "carbon peak, carbon neutral", ua hoʻomaka ka ʻoihana kaʻa ikaika hou o Kina i kahi manawa mōʻaukala hou. I ka makahiki 2021, ua hōʻea ke kūʻai aku o nā kaʻa kaʻa hou i ka 6.5 miliona, a ua hōʻea nā hoʻouna ʻana i nā pā uila i 317GWh, a ʻoi aku ka 100.63% i kēlā me kēia makahiki. Ua hōʻea ke kūʻai kaʻa kaʻa hou o Kina i 3.52 miliona mau ʻāpana, a ua hōʻea ka hoʻouna ʻana i nā pā uila i ka 226GWh, ʻoi aku ka 182.50 pakeneka o ka makahiki ma ka makahiki. Ua manaʻo ʻia e hiki i ka 1,550GWh i ka 1,550GWh i 2025 a me 3,000GWh i 2030. E mālama ka mākeke Kina i kona kūlana ma ke ʻano he mākeke mana nui loa ma ka honua me kahi mākeke paʻa o 50%.
