Ukuhlukaniswa kwe-A. petroleum coke
I-petroleum coke iyi-distillation kawoyela ongahluziwe izoba ukuhlukaniswa okulula nokukhulu kwamafutha, uwoyela osindayo bese kuba ngenqubo yokuqhekeka okushisayo, okuguqulwe kube imikhiqizo, kusukela ekubukekeni, i-coke ngesimo esingajwayelekile, usayizi webhulokhi elimnyama (noma izinhlayiya), ukukhanya kwensimbi, izinhlayiya ze-coke ezinesakhiwo esinezimbobo, ukwakheka kwe-carbon okuyinhloko, Ukubamba okungu-80wt%. (wt=isisindo)
Ngokwendlela yokucubungulaingahlukaniswa ibei-coke eluhlazafuthii-coke ephekiweOkokuqala kutholakala ngombhoshongo we-coke wedivayisi ye-coking ephuzile, eyaziwa nangokuthi i-i-coke yokuqalaLokhu kokugcina kukhiqizwa yi-calcination (1300°C), eyaziwa nangokuthii-coke ene-calcined.
Ngokusho kokuqukethwe kwesulfure, ingahlukaniswa ibei-coke yesulfure ephezulu(okuqukethwe kwesibabule kungaphezu kwalokho4%), i-coke yesulfure ephakathi(okuqukethwe kwesibabule2%-4%) kanyei-coke yesulfure ephansi(okuqukethwe kwesibabule kungaphansi kuka2%).
Ngokusho kwesakhiwo esincane esihlukile, ingahlukaniswa ibei-sponge cokefuthii-coke yenaliti. Owangaphambili onezimbobo ezincane njenge-spongy, owaziwa nangokuthii-coke evamileLesi sakamuva siminyene njenge-fiber, esaziwa nangokuthii-coke esezingeni eliphezulu.
Ngokwezinhlobo ezahlukeneingahlukaniswa ibei-coke yenaliti, i-coke eqoshiwe or i-coke eyindilinga, i-sponge coke, i-coke ewuphuphuizinhlobo ezine.
B. umkhiqizo we-coke kaphethiloli
Iningi le-coke kaphethiloli ekhiqizwa eShayina lingelama-coke aphansi esibabule, asetshenziswa kakhulu e-ukuncibilikisa i-aluminiumfuthiukukhiqizwa kwe-graphite.Esinye sisetshenziswa kakhuluimikhiqizo yekhabhoni, njengei-electrode ye-graphite, i-arc ye-anode, esetshenziselwainsimbi, izinsimbi ezingezona insimbi; Imikhiqizo ye-silicon eyenziwe nge-carbon, njengezinhlobonhloboamasondo okugaya, isihlabathi,iphepha lesihlabathi, njll.; I-calcium carbide yezentengiselwano yokukhiqiza i-fibre yokwenziwa, i-acetylene neminye imikhiqizo; Ingasetshenziswa futhi njengophethiloli, kodwa uma yenza uphethiloli, idinga ukusebenzisa umshini wokugaya olinganisiwe ukuze ikwazi ukugaya kahle kakhulu. Ngemva kokwenza uphuphu we-coke ngemishini, ingashiswa. Uphuphu we-coke usetshenziswa kakhulu njengophethiloli kwezinye izimboni zeglasi kanye nezitshalo zokulahla amanzi amalahle.
Ngokusho kweNational Bureau of Statistics, umkhiqizo we-petroleum coke eShayina ngo-2020 wawungamathani ayizigidi ezingu-29.202, okwenyuka ngo-4.15% ngonyaka, kanti kusukela ngoJanuwari kuya ku-Ephreli 2021, umkhiqizo we-petroleum coke eShayina wawungamathani ayizigidi ezingu-9.85.
Ukukhiqizwa kwe-petroleum coke eShayina kugxile kakhulu empumalanga yeShayina, enyakatho-mpumalanga yeShayina naseNingizimu yeShayina, kanye nokukhiqizwa okuphezulu kakhulu empumalanga yeShayina. Esifundeni sonke saseMpumalanga yeShayina, isifundazwe saseShandong sinomkhiqizo ophezulu kakhulu we-petroleum coke, ofinyelele amathani ayizigidi eziyi-10.687 ngo-2020. Umkhiqizo we-petroleum coke esifundazweni saseShandong awugcini nje ngokuba ngowokuqala empumalanga yeShayina, kodwa futhi ubekwa phambili kuzo zonke izifundazwe namadolobha aseShayina, futhi umkhiqizo we-petroleum coke uphakeme kakhulu kunezinye izifundazwe namadolobha.
C. Ukungenisa nokuthumela ngaphandle i-coke kaphethiloli
IShayina ingenye yamazwe angenisa kakhulu i-petroleum coke, etholakala kakhulu e-United States, eSaudi Arabia naseRussia. Ngokusho kwedatha ye-China Customs, inani lokungeniswa kwe-petroleum coke eShayina kusukela ngo-2015 kuya ku-2020 libonise ukuthambekela okukhuphukayo. Ngo-2019, inani lokungeniswa kwe-petroleum coke eShayina lalingamathani ayizigidi ezingu-8.267, kanti ngo-2020, lalingamathani ayizigidi ezingu-10.277, okuwukwenyuka okungu-24.31% uma kuqhathaniswa no-2019.
Ngo-2020, inani lokungeniswa kwe-Petroleum coke eShayina lalingu-USD 1.002 billion, lehle ngo-36.66% unyaka nonyaka. Ngo-2020, inani lokungeniswa kwe-petroleum coke lifinyelele esicongweni salo, kodwa inani lokungeniswa kwe-petroleum coke lehlile. Njengoba umnotho womhlaba wonke uthinteke kakhulu ubhubhane lwe-COVID-19, intengo ye-petroleum coke emakethe yamazwe ngamazwe nayo yehlile, okuye kwakhuthaza ukungeniswa kwe-petroleum coke eShayina futhi kwandise inani lokungeniswa kwe-petroleum coke, kodwa kwehlisa inani lokungeniswa.
Ngokusho kwedatha ye-China Customs, ukuthunyelwa kwe-coke kaphethiloli eShayina kubonise ukwehla, ikakhulukazi ngo-2020 ngenxa yomthelela we-COVID-19, ukuthunyelwa kwe-coke kaphethiloli eShayina kwehle kakhulu, ngo-2020, ukuthunyelwa kwe-coke kaphethiloli eShayina kwehle kwaya ku-1.784 million DOLLARS, ukwehla konyaka nonyaka kwama-22.13%; Inani lokuthunyelwa kwamanye amazwe lalingu-$459 million, lehle ngo-38.8% ngonyaka.
D. Umkhuba wokuthuthukiswa kwemboni ye-petroleum coke
Ngokuhamba kwesikhathi, imakethe ye-petroleum coke isagcwele ukungaqiniseki okuningi, futhi iphethini yokuhlinzekwa kanye nesidingo se-petroleum coke isabhekene nezinselele eziningi. Ngokombono wesakhiwo samandla, esikhathini esifushane, ngenxa yokulethwa kancane kwamandla e-hydrogenation kawoyela osele, ukulethwa kwedivayisi ye-coking okulibazisekile kuseyisiqondiso esiyinhloko. Ngokuhamba kwesikhathi, uhlangothi lokuhlinzekwa kwe-petroleum coke luzovinjelwa ukuvikelwa kwemvelo, izinqubomgomo nezinye izici, futhi kuzoqhubeka nokuba nobuchwepheshe obusha kanye nezinye izinto ezinobungani nemvelo. Inqubomgomo yokuvikela imvelo iya ngokuya iba yinto evamile, futhi ukukhiqizwa akunakunqunyelwa ukuze kufezwe ukukhishwa okuphansi kakhulu. Ngokuthuthuka kwamadivayisi okuvikela imvelo amabhizinisi, umthelela wenqubomgomo yokuvikela imvelo emakethe uzoncipha, futhi ithonya lobudlelwano bokunikezwa kwemakethe kanye nesidingo kanye nentengo yokuthenga izinto zokusetshenziswa zamabhizinisi lizothuthukiswa.
Ohlangothini lwesidingo, imboni ye-petroleum coke ezolandela izoqhubeka nokwethula izinselele ezahlukene zomnotho, izici zenqubomgomo, amabhizinisi e-aluminium e-electrolytic okwamanje angaphansi kwe-alumina, intengo kagesi, izindleko ziphezulu ukuze kube nenzuzo yokukhuluma ngayo, ngakho-ke izinkampani ze-aluminium zesikhathi esizayo zinenzuzo enkulu, njengoba ukwakheka kwemakethe ye-aluminium kuzoshintsha kancane kancane, kuzodlulisela kancane kancane umthamo, Kuzothinta iphethini kanye nentuthuko yemakethe ye-anode ebhakiwe kusengaphambili kanye nemakethe ye-carbon esikhathini esizayo.
Esikhathini esimaphakathi neside, isimo sezomnotho esikhulu, izinqubomgomo zemboni kazwelonke, isakhiwo sokuhlinzekwa komkhiqizo, izinguquko zempahla, amanani ezinto zokusetshenziswa, ukusetshenziswa okuphansi, izimo eziphuthumayo, njll., cishe kuzoba yizinto ezihamba phambili ezithinta imakethe ye-oil coke ezigabeni ezahlukene. Ngakho-ke, amabhizinisi kufanele ahlaziye isimo samanje semboni ye-oil coke, afunde kabanzi ngezinqubomgomo ezifanele ekhaya nakwamanye amazwe, abikezele isiqondiso sentuthuko yesikhathi esizayo semakethe ye-oil coke, agweme izingozi ngesikhathi esifanele, abambe amathuba, ushintsho olufika ngesikhathi kanye nokusungula izinto ezintsha, kuyisisombululo sesikhathi eside.
