Ngā Rerekētanga Matua i waenga i te Petroleum Coke me te Needle Coke me ō rāua Pānga ki te Kounga o te Irahiko
I. Ngā Rerekētanga o ngā Rauemi Mata me ngā Tukanga Whakaputa
Kōka hinu
- Ngā Rauemi Mata: He mea hanga te nuinga mai i te hinu taumaha, i te hinu toenga rānei mai i te whakatōnga hinu mata, he nui te poke (hei tauira, te whanariki, te vanadium, te nickel).
- Tukanga: I hangaia mā te whakaroa i te tunu, ka hanga he hanganga rite ki te hautai koretake i muri i te pakaru i te pāmahana teitei, me te nui o ngā pūwero (tae atu ki te >0.3 cm³/g) me te ngawari ki te mimiti i te makuku.
- Utu: He tukanga whakaputa māmā me ngā utu iti ake, engari he nui ngā rerekētanga o te kounga nā te mea e whakawhirinaki ana ki te pumau o ngā rauemi mata.
Koka ngira
- Ngā Rauemi Mata: Me whakamahi he hinu toenga hinu iti-whāwhā, iti-hauota (hei tauira, te parai hinu pakaru whakaterenga) he papa tāra waro rānei, me te tino whakahaere i te poke.
- Tukanga: Kei roto ko te maimoatanga o mua i ngā rauemi mata, te whakaroa i te tunu, me te whakapūkara i te pāmahana tino teitei (1,200–1,400°C), ka hua ake he tioata waro tino hāngai e hanga ana i tētahi hanganga muka.
- Utu: He tukanga whakaputa uaua, he maha ngā wā ka nui ake ngā utu i te kōka hinu noa, engari he pai ake te mahi a te hua.
II. Ngā Pānga ki te Kounga o te Hikohiko
Te Arahi Hiko
- Koka hinu: He ātete teitei, he nui te pānga o ngā poke (hei tauira, te whanariki, te vanadium). Ka puta he waikura hau i te kōka whanariki teitei i te wā o te electrolysis, ka puta te parahanga taiao me te heke o te kawe hiko.
- Koka Niho: He iti te ātete (he inenga matua mō te aromatawai kounga mā te ātete paura), e whakarite ana i te kawe hiko pai rawa atu, te whakaiti i te whakapaunga pūngao, me te whakapai ake i te pai o te iahiko.
Te Pūmautanga Wera me te Ātete Waikura
- Petroleum Coke: He nui te tauwehenga whakawhanui wera (CTE), ka pakaru i raro i ngā pāmahana teitei, he iti te ātete ki te waikura, ka tere ake te paunga o te hiko.
- Needle Coke: He iti te CTE me te ātete kaha ki ngā ru wera, e pupuri ana i te pumau o te hanganga i ngā pāmahana neke atu i te 3,000°C me te whakaroa i te roa o te ora o te hiko.
Te Kaha Mīhini me te Ātete ki te Waikura
- Koka hinu: He iti te kaha o te matūriki, ka ngawari ki te pakaru i roto i ngā otinga cryolite kaha, ka nui haere te whakamahinga.
- Needle Coke: Ka marara pai te ahotea e te hanganga muka, ka ātete pai ki te pakū ā-mīhini, he mea tino pai mō ngā taiao uaua pēnei i te hanga maitai i roto i te oumu pewa hiko kaha teitei.
Te Whakahaere i te Parakore me te Ritenga o te Hua
- Petroleum Coke: He rerekētanga nui o te ihirangi poke (hei tauira, Ni, V, Ca), e whakaohooho ana i ngā tauhohenga waikura anode, e whakararuraru ana i te mahi hiko me te whakaiti i te pai o te hiko konumohe.
- Needle Coke: Ngā taumata poke tino iti e tutukihia ana mā te whakamahine wai hohonu me te whakapūkara pakari, kia tino rite ai te hua mō te hanga hiko kounga teitei.
III. Ngā Whakamahinga me te Uara Ōhanga
Kōka hinu
- Ngā Whakamahinga Matua: Ngā wahie ahumahi (hei tauira, ngā oumu sima, ngā oumu karāhe), ngā rauemi waro iti te kounga (hei tauira, ngā irahiko karāhe taketake, te whakapiri anode).
- Ngā Here: Te hekenga o te mākete mō te kōka whanariki nui nā runga i ngā ture taiao, kāore i te pai mō ngā tono teitei.
Koka ngira
- Ngā Whakamahinga Matua: Uara Ōhanga: E 5–10 ngā wā teitei ake te utu i te kōka hinu noa, me te pikinga o te tono nā te whanaketanga o ngā hangarau pūngao hou.
- Ngā irahiko karāhe tino kaha: E 60% te nui o te hiahia katoa mō te kōka ngira, he mea nui mō te hanga maitai o te oumu pewa hiko.
- Ngā āwhata pākahiko lithium-ion kounga teitei: Ko te hanganga paparanga me te tioata ka āwhina i te tohatoha lithium-ion, ka whakarei ake i te pai o te utu/tuku pākahiko.
- Ngā hua karāpeti motuhake: Pērā i te karāpeti karihi me ngā rauemi karāpeti kawe wera nui.
IV. Ngā Auahatanga me ngā Wero o te Ahumahi
Koka ngira:
- Te tere o te whakawhānui i te kaha o te whare (e matapaetia ana ka eke te kaha o te ngira koko hinu ki te 2.21 miriona tana/tau i te tau 2023), ahakoa kei te mau tonu te whakawhirinaki ki ngā kawemai mō ngā hua kounga teitei. He mea nui tonu ngā whanaketanga hangarau.
Kōka hinu:
- Ka pāngia ngā mākete waenga-ki-te-iti e ngā pēhanga taiao, e hiahiatia ana te pumau o te kounga mā roto i ngā tikanga whakarite-mua (hei tauira, te whakaranu i ngā rauemi mata mai i ngā pūtake rerekē). Heoi, kāore e taea te whakakapi i te ngira coke i roto i ngā tono utu nui.
