Ukususela ngo-2018 ukuya ku-2022, umthamo weeyunithi zokupheka ezicothayo eTshayina uye wanda kuqala waze wehla, kwaye umthamo weeyunithi zokupheka ezicothayo eTshayina ubonise umkhwa wokwanda unyaka nonyaka ngaphambi ko-2019. Ekupheleni ko-2022, umthamo weeyunithi zokupheka ezicothayo eTshayina wawumalunga ne-149.15 yezigidi zeetoni, kwaye ezinye iiyunithi zazidluliselwe kwaye ziqalisiwe ukusebenza. Ngomhla wesi-6 kweyeNkanga, ukondliwa okuphambili kweetoni ezi-2 zezigidi ngonyaka kweyunithi yokutya ecothayo yeShenghong Refining and Chemical Integration Project (Shenghong Refining and Chemical) kuphumelele kwaye kwavelisa iimveliso ezifanelekileyo. Umthamo weyunithi yokutya ecothayo eMpuma China uqhubekile nokukhula.
Ukusetyenziswa kwe-coke yepetroleum yasekhaya iyonke kubonise ukunyuka ukusuka ngo-2018 ukuya ku-2022, kwaye ukusetyenziswa kwe-coke yepetroleum yasekhaya iyonke kuhlale kungaphezulu kweetoni ezingama-40 ezigidi ukusuka ngo-2021 ukuya ku-2022. Ngo-2021, imfuno esezantsi yokunyuka yanda kakhulu kwaye izinga lokukhula kokusetyenziswa landa. Nangona kunjalo, ngo-2022, amanye amashishini asezantsi ayelumkile ekuthengeni ngenxa yempembelelo yobhubhane, kwaye izinga lokukhula kokusetyenziswa kwe-coke yepetroleum lehla kancinci laya kuthi ga kwi-0.7%.
Kwicandelo le-anode ebhakiweyo kwangaphambili, kubekho umkhwa okhulayo kwiminyaka emihlanu edlulileyo. Kwelinye icala, imfuno yasekhaya inyukile, kwaye kwelinye icala, ukuthunyelwa kwamanye amazwe kwe-anode ebhakiweyo kwangaphambili kubonakalise umkhwa okhulayo. Kwicandelo le-graphite electrode, uhlengahlengiso lwecala lokubonelela ukusuka ngo-2018 ukuya ku-2019 lusashushu, kwaye imfuno ye-graphite electrode ilungile. Nangona kunjalo, ngenxa yobuthathaka bemarike yentsimbi, inzuzo yokwenza intsimbi ye-arc furnace yombane iyanyamalala, imfuno ye-graphite electrode iyancipha kakhulu. Kwicandelo le-carburizing agent, ukusetyenziswa kwe-petroleum coke bekuzinzile kwiminyaka yakutshanje, kodwa ngo-2022, ukusetyenziswa kwe-petroleum coke kuya kwanda kakhulu ngenxa yokwanda kwe-carburizing agent njengemveliso ye-graphitization. Imfuno ye-petroleum coke kwintsimi yamafutha ixhomekeke kakhulu kumahluko wamaxabiso phakathi kwamalahle ne-petroleum, ngoko ke iyatshintshatshintsha kakhulu. Ngo-2022, ixabiso le-petroleum coke liya kuhlala liphezulu, kwaye inzuzo yamaxabiso amalahle iya kwanda, ngoko ke ukusetyenziswa kwe-petroleum coke kuya kuncipha. Imakethi yesinyithi sesilicon kunye ne-silicon carbide kwiminyaka emibini edlulileyo ilungile, kwaye ukusetyenziswa kwayo iyonke kuyanda, kodwa ngo-2022, ibuthathaka kunonyaka ophelileyo, kwaye ukusetyenziswa kwe-petroleum coke kwehla kancinci. Intsimi yezinto ze-anode, exhaswa ngumgaqo-nkqubo welizwe, ibikhula minyaka le kwiminyaka yakutshanje. Ngokuphathelele ukuthumela ngaphandle i-calcined char, ngokwanda kwemfuno yasekhaya kunye nenzuzo ephezulu yasekhaya, ishishini lokuthumela ngaphandle i-calcined char liye lancipha.
Uqikelelo lwemarike yexesha elizayo:
Ukususela ngo-2023, imfuno yeshishini le-petroleum coke lasekhaya inokunyuka ngakumbi. Ngokwanda okanye ukupheliswa kwamandla athile okucoca, kwiminyaka emihlanu ezayo, amandla emveliso yonyaka ka-2024 aya kufikelela kwinqanaba eliphezulu aze anciphe aye kwimeko ezinzileyo, kwaye amandla emveliso yonyaka ka-2027 kulindeleke ukuba afikelele kwi-149.6 yezigidi zeetoni ngonyaka. Kwangaxeshanye, ngokwandiswa ngokukhawuleza kwamandla emveliso yezixhobo ze-anode kunye namanye amashishini, imfuno ifikelele kwinqanaba elingazange libonwe ngaphambili. Kulindeleke ukuba imfuno yasekhaya yeshishini le-petroleum coke iya kugcina ukuguquguquka konyaka kweetoni ezingama-41 ezigidi kwiminyaka emihlanu ezayo.
Ngokuphathelele kwimarike yokugqibela yemfuno, urhwebo lulonke lulungile, ukusetyenziswa kwezinto ze-anode kunye nentsimi ye-graphitization kuyaqhubeka nokwanda, imfuno yentsimbi yemarike ye-aluminium carbon inamandla, inxalenye ye-coke engenisiweyo ingena kwimarike ye-carbon ukongeza unikezelo, kwaye imarike ye-petroleum coke isabonisa imeko yomdlalo wemfuno yonikezelo.
