A. ukuhlukaniswa kwe-petroleum coke
I-petroleum coke iyi-distillation kawoyela ongahluziwe izoba nokuhlukaniswa kwamafutha alula futhi asindayo, uwoyela osindayo bese kuthi ngenqubo yokuqhekeka okushisayo, iguqulwe ibe yimikhiqizo, isuka ekubukekeni, i-coke yesimo esingajwayelekile, usayizi we-black block (noma izinhlayiya), i-metallic luster, izinhlayiya ze-coke ezinesakhiwo esinama-porous, ukwakheka kwento eyinhloko ye-carbon, Bamba u-80wt%. (wt=isisindo)
Ngokusho kwendlela yokucubungulazingahlukaniswa zibei-coke eluhlazafuthii-coke ephekiwe. Owokuqala utholwa umbhoshongo we-coke wedivaysi yokupheka ebambezelekile, eyaziwa nangokuthi ii-coke yangempela; Lesi sakamuva sikhiqizwa ngokubala (1300°C), eyaziwa nangokuthii-coke eqoshiwe.
Ngokusho kokuqukethwe kwesibabule, ingahlukaniswa ibei-coke ephezulu yesibabule(okuqukethwe kwesibabule kungaphezulu4%), i-coke yesibabule esiphakathi(okuqukethwe kwesibabule kungu2%-4%) kanyei-coke ephansi yesibabule(okuqukethwe kwesibabule kuncane kune2%).
Ngokusho kwe-microstructure ehlukene, ingahlukaniswa ibeisipontshi cokefuthiinaliti coke. I-Porous yangaphambili njenge-spongy, eyaziwa nangokuthii-coke evamile. Eyokugcina iminyene njenge-fibrous, eyaziwa nangokuthii-coke yekhwalithi ephezulu.
Ngokusho kwamafomu ahlukenezingahlukaniswa zibeinaliti coke, i-projectile coke or i-coke eyindilinga, isipontshi coke, i-powder cokeizinhlobo ezine.
B. okukhipha i-petroleum coke
Iningi le-petroleum coke ekhiqizwa eShayina ingeye-low sulphur coke, esetshenziswa kakhuluukuncibilika kwe-aluminiumfuthiukwenziwa kwe-graphite.Enye isetshenziselwa ikakhulukaziimikhiqizo ye-carbon, njengei-graphite electrode, i-anode arc, esetshenziselwainsimbi, izinsimbi ezingenayo insimbi; Imikhiqizo ye-silicon ye-carbonized, njengezinhlobonhloboamasondo okugaya, isihlabathi,sand paper, njll.; I-calcium carbide yezohwebo yokukhiqiza i-fibre zokwenziwa, i-acetylene neminye imikhiqizo; Ingasetshenziswa futhi njengophethiloli, kodwa lapho yenza uphethiloli, idinga ukusebenzisa isigayo somthelela esihleliwe ukuze igaye nge-ultrafine. Ngemuva kokwenza i-coke powder ngokusebenzisa imishini, ingashiswa. I-coke powder isetshenziswa kakhulu njengophethiloli kwezinye izimboni zezingilazi nasezitshalweni ezidaka amanzi amalahle.
Ngokusho kweNational Bureau of Statistics, umkhiqizo we-petroleum coke waseChina ngo-2020 wawungamathani ayizigidi ezingama-29.202, wenyuka ngo-4.15% unyaka nonyaka, kanti kusukela ngoJanuwari kuya ku-Ephreli 2021, ukuphuma kwe-petroleum coke yaseChina bekungamathani ayizigidi eziyi-9.85.
Ukukhiqizwa kwe-petroleum coke e-China kugxile kakhulu empumalanga yeChina, enyakatho-mpumalanga yeChina naseNingizimu China, ngokukhiqizwa okuphezulu kakhulu empumalanga yeChina. Kuso sonke isifunda esisempumalanga yeChina, isifundazwe saseShandong sinomkhiqizo ophakeme kakhulu we-petroleum coke, ofinyelele amathani ayizigidi ezingu-10.687 ngo-2020. Ukukhishwa kwe-petroleum coke esifundazweni saseShandong akugcini nje ngokuba ngowokuqala empumalanga yeChina, kodwa futhi kuqala kuzo zonke izifundazwe namadolobha. eShayina, futhi umkhiqizo we-petroleum coke uphakeme kakhulu kunezinye izifundazwe namadolobha.
C. Ukungenisa nokuthekelisa i-petroleum coke
I-China ingelinye lamazwe angenisa kakhulu i-petroleum coke, ephuma ikakhulukazi e-United States, eSaudi Arabia naseRussia. Ngokusho kwedatha ye-China Customs, umthamo wokungenisa we-petroleum coke e-China kusukela ngo-2015 kuya ku-2020 ubonise umkhuba okhuphukayo jikelele. Ngo-2019, umthamo wokungenisa we-petroleum coke eChina wawungamathani ayizigidi eziyi-8.267, kwathi ngo-2020, wawungamathani ayizigidi eziyi-10.277, okuwukunyuka kwama-24.31% uma kuqhathaniswa no-2019.
Ngo-2020, inani lokungenisa kwe-Petroleum coke e-China lalingama-USd 1.002 billion, lehle ngo-36.66% unyaka nonyaka. Ngo-2020, umthamo wokungenisa we-petroleum coke wafinyelela inani eliphakeme, kodwa inani le-petroleum coke lehla. Njengoba umnotho womhlaba uhlaselwe kanzima wubhubhane lwe-COVID-19, intengo ye-petroleum coke emakethe yamazwe omhlaba nayo yehlile, okukhuthaze ukungeniswa kwe-petroleum coke eChina futhi kwenyusa ivolumu yokungenisa kwe-petroleum coke, kodwa yehlisa izinga lokungeniswa kwe-petroleum coke. inani lokungenisa.
Ngokusho kwedatha ye-China Customs, ukuthunyelwa kwe-petroleum coke yaseChina kukhombise ukwehla, ikakhulukazi ngo-2020 ngenxa yomthelela we-COVID-19, ukuthunyelwa kwe-petroleum coke yaseChina kwehle kakhulu, ngo-2020, ukuthunyelwa kwe-petroleum coke yaseChina kwehle kwafika ku-1.784 million DOLLARS, a ukwehla konyaka nonyaka ngama-22.13%; Inani lempahla ethunyelwa ngaphandle lalingamaRandi ayizigidi ezingama-459, lehle ngo-38.8% unyaka nonyaka.
D. Ukuthuthukiswa kwemboni ye-petroleum coke
Ngokuhamba kwesikhathi, imakethe ye-petroleum coke isagcwele ukungaqiniseki okuningi, futhi iphethini yokuhlinzeka kanye nesidingo se-petroleum coke isabhekene nezinselele ezengeziwe. Ngokombono wesakhiwo samandla, esikhathini esifushane, ngenxa yokulethwa kancane komthamo we-hydrogenation kawoyela osalayo, ukulibaziseka kokulethwa kwedivayisi yokupheka kuseyisiqondiso esiyinhloko. Ngokuhamba kwesikhathi, uhlangothi lokuhlinzekwa kwe-petroleum coke nalo luzokhawulelwa ukuvikelwa kwemvelo, izinqubomgomo kanye nezinye izici, futhi kusazoqhubeka nokuba khona ubuchwepheshe obusha kanye nezinye izinto ezizongena endaweni ezungezile. Inqubomgomo yokuvikela imvelo kancane kancane iba ngokwejwayelekile, futhi ukukhiqizwa akukwazi ukukhawulelwa ukuze kuzuzwe ukukhishwa kwekhabhoni ephansi kakhulu. Ngokuthuthukiswa kwemishini yokuvikela imvelo yamabhizinisi, umthelela wenqubomgomo yokuvikela imvelo emakethe uzoba buthaka, futhi umthelela wokunikezwa kwemakethe nobudlelwano besidingo kanye nentengo yokuthengwa kwezinto ezingavuthiwe zebhizinisi kuzothuthukiswa.
Uhlangothi lwesidingo, imboni ye-petroleum coke ezansi nomfula izoqhubeka nokwethula izinselelo ezehlukene zomnotho, izici zenqubomgomo, amabhizinisi e-electrolytic aluminium okwamanje angaphansi kwe-alumina, intengo kagesi, izindleko ziphezulu ukuba nenzuzo ukukhuluma ngayo, ngakho izinkampani ze-aluminium zesikhathi esizayo zineketanga lemboni eliphelele inzuzo enkulu, njengoba ukwakheka kwemakethe ye-aluminium kuzoshintsha kancane kancane, phakathi nendawo kuzodlulisa umthamo kancane kancane, Kuzothinta iphethini nokuthuthukiswa kwemakethe ye-anode ephekwe ngaphambili kanye nemakethe ye-carbon esikhathini esizayo.
Esikhathini esimaphakathi neside, imvelo yezomnotho omkhulu, izinqubomgomo zemboni kazwelonke, ukwakheka kokuhlinzekwa kwemikhiqizo, izinguquko zezimpahla, amanani entengo yezinto ezingavuthiwe, ukusetshenziswa okuphansi komfula, izimo eziphuthumayo, njll., kungenzeka kube yizinto ezihamba phambili ezithinta imakethe kawoyela ye-coke ngezigaba ezahlukene. Ngakho-ke, amabhizinisi kufanele ahlaziye isimo se-quo yemboni ye-petroleum coke, afunde kabanzi ngezinqubomgomo ezifanele ekhaya nakwamanye amazwe, abikezele intuthuko yesikhathi esizayo yemakethe ye-petroleum coke, ukugwema ubungozi ngesikhathi esifanele, ukubamba amathuba, uguquko olufika ngesikhathi kanye nokuqamba okusha, kuyisikhathi eside. isisombululo.
