Udidi lwe-A. petroleum coke
I-petroleum coke yi-oyile ekrwada eyahlulahlula ioyile ibe lula kwaye inzima, ioyile enzima ize emva koko idlule kwinkqubo yokuqhekeka okushushu, iguqulwe ibe ziimveliso, ukusuka kwimbonakalo, i-coke ibe yimilo engacwangciswanga, ubungakanani bebhloko emnyama (okanye amasuntswana), ukukhazimla kwesinyithi, amasuntswana e-coke anesakhiwo esinemingxuma, ukwakheka kwekhabhoni okuphambili, Ukubamba i-80wt%. (wt=weight)
Ngokwendlela yokucubungulainokwahlulwahlulwa ibei-coke eluhlazakwayei-coke ephekiweyoEyokuqala ifunyanwa yi-coke tower yesixhobo se-delayed coking, esaziwa ngokuba yi-i-coke yokuqalaLe yokugqibela iveliswa yi-calcination (1300°C), eyaziwa ngokuba yi-i-coke ene-calcined.
Ngokwesiqulatho sesalfure, inokwahlulwahlulwa ibei-coke enesalfure eninzi(umxholo wesalfure ungaphezulu4%), i-coke yesalfure ephakathi(umxholo wesalfure ngu2%-4%kunyei-coke yesalfure ephantsi(umxholo wesalfure ungaphantsi2%).
Ngokwezakhiwo ezahlukeneyo ze-microstructure, inokwahlulwahlulwa ibei-sponge cokekwayei-coke yenalitiLe yangaphambili inemingxuma efana ne-spongy, ekwaziwa ngokuba yi-i-coke eqhelekileyoLe yokugqibela ixinene njenge-fibrous, ekwaziwa ngokuba yi-i-coke esemgangathweni ophezulu.
Ngokweefom ezahlukeneyoinokwahlulwahlulwa ibei-coke yenaliti, i-coke ephuliweyo or i-coke engqukuva, i-sponge coke, i-powder cokeiintlobo ezine.
B. imveliso ye-coke yepetroliyam
Uninzi lwe-petroleum coke eveliswa eTshayina yeyase-low sulfur coke, esetyenziswa kakhulu e-China.ukunyibilikisa i-aluminiyamkwayeukwenziwa kwegrafayithi.Enye isetyenziselwa ikakhuluiimveliso zekhabhoni, njengei-electrode yegrafayithi, i-arc ye-anode, isetyenziselwaintsimbi, iintsimbi ezingezizo ezomileyo; Iimveliso zesilicon ezenziwe ngekhabhoni, njengeentlobo ngeentloboamavili okugaya, isanti,iphepha lesanti, njl.njl.; I-calcium carbide yorhwebo yokuvelisa ifayibha yokwenziwa, i-acetylene kunye nezinye iimveliso; Ingasetyenziswa njengepetroli, kodwa xa isenza ipetroli, kufuneka isebenzise i-graded impact mill ukwenza i-ultrafine grinding. Emva kokwenza i-coke powder ngezixhobo, ingatshiswa. I-coke powder isetyenziswa kakhulu njengepetroli kwezinye iifektri zeglasi kunye nezityalo zokulunywa kwamanzi amalahle.
Ngokutsho kweNational Bureau of Statistics, imveliso ye-petroleum coke eTshayina ngo-2020 yayiziitoni ezingama-29.202 ezigidi, inyuke nge-4.15% ngonyaka, kwaye ukususela ngoJanuwari ukuya ku-Epreli 2021, imveliso ye-petroleum coke eTshayina yayiziitoni ezizizigidi ezili-9.85.
Imveliso ye-petroleum coke eTshayina igxile kakhulu empuma yeTshayina, kumantla-mpuma eTshayina naseMzantsi China, kunye nemveliso ephezulu empuma yeTshayina. Kuwo wonke ummandla wasempuma yeTshayina, iphondo laseShandong linemveliso ephezulu ye-petroleum coke, efikelele kwi-10.687 yezigidi zeetoni ngo-2020. Imveliso ye-petroleum coke kwiphondo laseShandong ayipheleli nje ekubekweni kwindawo yokuqala empuma yeTshayina, kodwa ikwabekwa kwindawo yokuqala kuzo zonke iiphondo nezixeko zaseTshayina, kwaye imveliso ye-petroleum coke iphezulu kakhulu kunezinye iiphondo nezixeko.
C. Ukungenisa nokuthumela ngaphandle i-coke yepetroliyam
I-China yenye yezona zinto ziphambili ezithumela i-petroleum coke kwamanye amazwe, ezivela e-United States, eSaudi Arabia naseRashiya. Ngokwedatha ye-China Customs, umthamo wokungenisa i-petroleum coke e-China ukususela ngo-2015 ukuya ku-2020 ubonise ukunyuka ngokubanzi. Ngo-2019, umthamo wokungenisa i-petroleum coke e-China wawuziitoni ezi-8.267 yezigidi, kwaye ngo-2020, wawuziitoni ezi-10.277 yezigidi, ukunyuka kwe-24.31% xa kuthelekiswa no-2019.
Ngowama-2020, isixa se-petroleum coke esingeniswe eTshayina sasiyi-USD 1.002 yeebhiliyoni, sehle ngama-36.66% ngonyaka. Ngowama-2020, isixa se-petroleum coke esingeniswe kwamanye amazwe sifikelele kwincopho yaso, kodwa ixabiso le-petroleum coke elingeniswe kwamanye amazwe lehla. Njengoko uqoqosho lwehlabathi lubethwe kakhulu ngubhubhane we-COVID-19, ixabiso le-petroleum coke kwimarike yamazwe ngamazwe nalo liye lehla, nto leyo eye yakhuthaza ukungeniswa kwe-petroleum coke eTshayina yaza yanyusa umthamo wokungeniswa kwe-petroleum coke, kodwa yanciphisa isixa sokungeniswa kwamanye amazwe.
Ngokwedatha ye-China Customs, ukuthunyelwa kwe-petroleum coke eTshayina kubonise ukuhla kwesimo, ngakumbi ngo-2020 ngenxa yempembelelo ye-COVID-19, ukuthunyelwa kwe-petroleum coke eTshayina kwehle kakhulu, ngo-2020, ukuthunyelwa kwe-petroleum coke eTshayina kwehle ukuya kwi-1.784 yezigidi zeerandi, ukwehla konyaka nonyaka kwe-22.13%; Ixabiso lokuthunyelwa kwamanye amazwe yayiyi-$459 yezigidi, lehle nge-38.8% ngonyaka.
D. Uphuhliso lwemizi-mveliso ye-petroleum coke
Kwixesha elide, imakethi ye-petroleum coke isagcwele ukungaqiniseki okuninzi, kwaye indlela yokubonelela kunye nemfuno ye-petroleum coke isajongene nemingeni emininzi. Ngokwembono yesakhiwo somthamo, kwixesha elifutshane, ngenxa yokuhanjiswa kancinci komthamo we-hydrogenation yeoyile eseleyo, ukuhanjiswa kwezixhobo ze-coking okulibazisekileyo kuseyona ndlela iphambili. Kwixesha elide, icala lokubonelela le-petroleum coke liya kuthintelwa kukhuseleko lokusingqongileyo, imigaqo-nkqubo kunye nezinye izinto, kwaye kuya kuqhubeka kukho ubuchwepheshe obutsha kunye nezinye izinto ezinobuhlobo nokusingqongileyo. Umgaqo-nkqubo wokukhusela okusingqongileyo uya usiba yinto eqhelekileyo kancinci kancinci, kwaye imveliso ayinakuthintelwa ukufezekisa ukukhutshwa komoya okuphantsi kakhulu. Ngokuphuculwa kwezixhobo zokukhusela okusingqongileyo zamashishini, impembelelo yomgaqo-nkqubo wokukhusela okusingqongileyo kwimarike iya kuba buthathaka, kwaye impembelelo yobudlelwane bokubonelela ngemarike kunye nemfuno kunye nexabiso lokuthenga izinto eziluhlaza zamashishini iya kuphuculwa.
Icala leemfuno, ishishini le-petroleum coke elisezantsi liza kuqhubeka nokwazisa imingeni eyahlukeneyo yezoqoqosho, imiba yemigaqo-nkqubo, amashishini e-aluminium e-electrolytic okwangoku aphantsi kwe-alumina, ixabiso lombane, iindleko ziphezulu zokuba nenzuzo, ngoko ke iinkampani ze-aluminium zexesha elizayo zinenzuzo enkulu, njengoko uyilo lwemarike ye-aluminium luya kutshintsha kancinci, phakathi kuya kudlulisela umthamo kancinci kancinci, Kuya kuchaphazela ipateni kunye nophuhliso lwemarike ye-anode ebhakiweyo kwangaphambili kunye nemarike yekhabhoni kwixesha elizayo.
Kwixesha eliphakathi nelide, imeko-bume yezoqoqosho olukhulu, imigaqo-nkqubo yelizwe yeshishini, ulwakhiwo lobonelelo lwemveliso, utshintsho lwezinto ezisetyenzisiweyo, amaxabiso ezinto eziluhlaza, ukusetyenziswa okusezantsi, iimeko ezingxamisekileyo, njl.njl., kusenokwenzeka ukuba zibe zizinto eziphambili ezichaphazela imarike yeoyile ye-coke kumanqanaba ahlukeneyo. Ke ngoko, amashishini kufuneka ahlalutye imeko ekhoyo kwishishini le-coke ye-coke, afunde ngakumbi ngemigaqo-nkqubo efanelekileyo ekhaya nakwamanye amazwe, aqikelele indlela yophuhliso lwexesha elizayo lwemarike ye-coke ye-coke, aphephe imingcipheko ngexesha elifanelekileyo, athathe amathuba, utshintsho olufike ngexesha kunye nokuvelisa izinto ezintsha, sisisombululo sexesha elide.
