[Needle Coke] Ntinye na nyocha nyocha na njirimara mmepe nke coke agịga na China
I. China si agịga coke ahịa ike
N'afọ 2016, ikike mmepụta coke coke zuru ụwa ọnụ bụ 1.07 nde tọn / afọ, na ikike mmepụta China nke agịga coke bụ tọn 350,000 / afọ, na-aza 32.71% nke ikike mmepụta ụwa. Ka ọ na-erule afọ 2021, ikike mmepụta coke coke zuru ụwa ọnụ mụbara ruo nde tọn 3.36 / afọ, n'ime nke ikike mmepụta China nke coke coke bụ nde tọn 2.29 kwa afọ, na-aza 68.15% nke ikike mmepụta ụwa. Ụlọ ọrụ mmepụta nke China nke agịga coke mụbara ruo 22. Ngụkọta ikike mmepụta nke ụlọ ọrụ coke agịga n'ime ụlọ mụbara site na 554.29% ma e jiri ya tụnyere 2016, ebe ikike mmepụta nke coke agịga si mba ọzọ kwụsiri ike. Ka ọ na-erule 2022, ikike mmepụta nke coke agịga nke China abawanyela na nde tọn 2.72, mmụba nke ihe dị ka ugboro 7.7, yana ọnụ ọgụgụ ndị na-emepụta coke coke nke China abawanyela ruo 27, na-egosi nnukwu mmepe nke ụlọ ọrụ ahụ, na-elele anya zuru ụwa ọnụ. , Ọnụ ọgụgụ coke agịga nke China na ahịa mba ụwa na-abawanye kwa afọ.
1. Ike mmepụta mmanụ nke coke agịga
Ike mmepụta nke coke agịga mmanụ-usoro mmanụ malitere ito ngwa ngwa site na 2019. Site na 2017 ruo 2019, ahịa ahịa China nke usoro mkpali agịga na-achịkwa usoro coal, ebe mmepe nke coke coke mmanụ na-adị ngwa ngwa. Ọtụtụ n'ime ụlọ ọrụ ndị dị ugbu a etinyere na mmepụta mgbe afọ 2018 gasịrị, na ikike mmepụta nke coke coke mmanụ na China ruru nde tọn 1.59 site na 2022. Mmepụta ahụ nọgidere na-abawanye kwa afọ. N'afọ 2019, ahịa elektrọd graphite na-agbadata gbadara nke ọma, na ọchịchọ coke agịga adịghị ike. N'afọ 2022, n'ihi mmetụta nke ọrịa COVID-19 na Olympics Winter na ihe omume ọha na eze ndị ọzọ, ọchịchọ ebelatala, ebe ọnụ ahịa dị elu, ụlọ ọrụ anaghị enwe mkpali imepụta ya, mmepụta mmepụta na-adịkwa ngwa ngwa.
2. Production ikike nke coal ihe agịga coke
Ikike imepụta coal ntụ ntụ coke na-anọgide na-abawanye kwa afọ, site na tọn 350,000 na 2017 ruo nde tọn 1.2 na 2022. Site na 2020, òkè ahịa nke ihe ọ̀tụ̀tụ̀ coal na-ebelata, na usoro mmanụ coke coke ga-aghọ ihe bụ isi nke coke agịga. N'ihe banyere mmepụta, ọ nọgidere na-eto eto site na 2017 ruo 2019. Site na 2020, n'otu aka ahụ, ọnụ ahịa ahụ dị elu na uru ahụ gbanwere. N'aka nke ọzọ, ọchịchọ nke graphite electrode adịghị mma.
Ⅱ Achọ nyocha nke agịga Coke na China
1. Nyocha ahịa nke ihe lithium anode
Site na mmepụta ihe na-adịghị mma, mmepụta kwa afọ nke ihe na-adịghị mma nke China mụbara nwayọọ nwayọọ site na 2017 ruo 2019. Na 2020, na-emetụta ịrị elu na-aga n'ihu nke ahịa ọnụ ahịa ọnụ ala, n'ozuzu mmalite nke batrị ike na-amalite ibuli, ahịa ahịa na-abawanye nke ukwuu. , na iwu nke ụlọ ọrụ electrode na-adịghị mma na-abawanye, na mmalite nke ụlọ ọrụ na-ebuli ngwa ngwa ma na-anọgide na-agbago elu. Na 2021-2022, mmepụta China nke lithium cathode ihe gosipụtara uto mgbawa, na-erite uru site na mmụba na-aga n'ihu nke ihu igwe azụmahịa nke ụlọ ọrụ ndị dị n'okpuru ala, mmepe ngwa ngwa nke ahịa ụgbọ ala ike ọhụrụ, nchekwa ike, oriri, obere ike na ahịa ndị ọzọ gosikwara dị iche iche. ogo uto, yana nnukwu ụlọ ọrụ ihe onwunwe cathode na-ejigide mmepụta zuru oke. A na-eme atụmatụ na mmepụta nke ihe electrode na-adịghị mma na-atụ anya ka ọ gafere 1.1 nde tọn na 2022, na ngwaahịa ahụ nọ n'ọnọdụ dị mkpụmkpụ, na atụmanya ngwa nke ihe electrode na-adịghị mma bụ sara mbara.
Ntu coke bụ ụlọ ọrụ elu nke batrị lithium na ihe anode, nke nwere njikọ chiri anya na mmepe batrị lithium na ahịa ihe cathode. Akụkụ ngwa nke batrị lithium gụnyere gụnyere batrị ike, batrị ndị ahịa na batrị nchekwa ike. Na 2021, batrị ike ga-aza 68%, batrị ndị ahịa maka 22%, yana batrị nchekwa ike maka 10% nke nhazi ngwaahịa batrị lithium ion nke China.
Batrị ike bụ isi akụrụngwa nke ụgbọ ala ume ọhụrụ. N'afọ ndị na-adịbeghị anya, site na mmejuputa atumatu “carbon peak, carbon neutral”, ụlọ ọrụ ụgbọ ala ike ọhụrụ nke China wetara ohere akụkọ ihe mere eme ọhụrụ. Na 2021, ire ụgbọ ala ọhụrụ zuru ụwa ọnụ ruru nde 6.5, na mbupu batrị ruru 317GWh, gbagoro 100.63% kwa afọ. Ire ụgbọ ala ọhụrụ nke China ruru nde 3.52, na mbupu batrị ruru 226GWh, gbagoro pasent 182.50 kwa afọ. A na-atụ anya na mbupu batrị ike zuru ụwa ọnụ ga-eru 1,550GWh na 2025 na 3,000GWh na 2030. Ahịa China ga-edobe ọnọdụ ya dị ka ahịa batrị batrị kachasị ukwuu n'ụwa na-enwe oke ahịa ahịa siri ike karịa 50%.
