A. udidi lwepetroleum coke
I-petroleum coke yi-distillation yeoli ekrwada iya kuba lula kunye nokwahlukana kweoli enzima, ioli enzima kwaye emva koko ngenkqubo yokuqhekeka okutshisayo, iguqulwe ibe yimveliso, ukusuka kwinkangeleko, i-coke yesimo esingaqhelekanga, ubungakanani bebhloko emnyama (okanye amaqhekeza), i-metallic luster, amaqhekeza e-coke anesakhiwo se-porous, eyona nto iphambili yokubunjwa kwekhabhoni, Bamba i-80wt%. (wt=ubunzima)
Ngokwendlela yokucubungulaingahlulwa ibeicoke eluhlazakwayei-coke ephekiweyo. Eyangaphambili ifunyenwe yinqaba yecoke yesixhobo sokupheka esilibazisekayo, esaziwa ngokuba yiicoke yokuqala; Le yokugqibela uveliswa calcination (1300 ° C), eyaziwa ngokubacoke calcined.
Ngokomxholo wesulfure, inokwahlulwa ibeicoke yesulfure ephezulu(umxholo wesulfure ungaphezulu kwe4%), icoke yesulfure ephakathi(umxholo wesulfure ngu2%-4%) kunyeicoke yesulfure ephantsi(umxholo wesulfure ungaphantsi kwe2%).
Ngokutsho kwe-microstructure eyahlukeneyo, inokwahlulwa ibeisiponji cokekwayeinaliti coke. I-porous yangaphambili njenge-spongy, eyaziwa ngokubaicoke eqhelekileyo. Le yokugqibela ixinene njenge fibrous, ekwaziwa njengeicoke ekumgangatho ophezulu.
Ngokweendlela ezahlukeneyoingahlulwa ibeinaliti coke, coke projectile or icoke engqukuva, isiponji coke, umgubo wecokeiintlobo ezine.
B. imveliso yepetroleum coke
Uninzi lwepetroleum coke eveliswa eTshayina yeyecoke yesulphur ephantsi, esetyenziswa kakhuluukunyibilikiswa kwealuminiyamkwayeukwenziwa kwegraphite.Enye isetyenziselwa ikakhuluiimveliso zekhabhoni, njengei-electrode yegraphite, i-anode arc, esetyenziselwaintsimbi, iintsimbi ezingenayo intsimbi; Iimveliso ze-silicon zekhabhoni, njengezohlukeneyoamavili okusila, isanti,iphepha lesanti, njl. I-calcium carbide yorhwebo yokuvelisa i-fiber synthetic, i-acetylene kunye nezinye iimveliso; Isenokusetyenziswa njengesibaso, kodwa xa kusenziwa isibaso, kufuneka isebenzise isisila esinempembelelo ehleliweyo ukwenza ukucola okugqithisileyo. Emva kokwenza i-coke powder ngokusebenzisa izixhobo, inokutshiswa. Umgubo wecoke usetyenziswa kakhulu njengamafutha kwezinye iifektri zeglasi kunye nezityalo eziludaka lwamanzi amalahle.
Ngokwe-Bureau yeSizwe ye-Statistics, imveliso ye-petroleum coke yase-China ngo-2020 yayiziitoni ezizigidi ezingama-29.202, inyuke nge-4.15% ngonyaka, kwaye ukususela ngoJanuwari ukuya ku-Epreli ka-2021, imveliso ye-petroleum coke yayiziitoni ezisi-9.85 sezigidi.
Imveliso ye-petroleum coke e-China igxile kakhulu kwimpuma ye-China, kumntla-mpuma we-China kunye ne-South China, kunye nemveliso ephezulu kwimpuma ye-China. Kuwo wonke ummandla osempuma yeTshayina, iphondo laseShandong linemveliso ephezulu yepetroleum coke, eyafikelela kwi-10.687 yezigidi zeetoni ngo-2020. Ukukhutshwa kwe-petroleum coke kwiphondo laseShandong akugcini nje kuqala kwimpuma yeChina, kodwa iphinda ibeke kuqala kuwo onke amaphondo kunye nezixeko. eTshayina, kwaye imveliso yepetroleum coke ingaphezulu lee kunamanye amaphondo nezixeko.
C. Ukungenisa kunye nokuthumela ngaphandle kwepetroleum coke
I-China lelinye labathengi abaphambili bepetroleum coke, ephuma ikakhulu eMelika, eSaudi Arabia naseRussia. Ngokutsho kwedatha ye-China Customs, umthamo wokungenisa i-petroleum coke e-China ukusuka kwi-2015 ukuya kwi-2020 ibonise ukunyuka ngokubanzi. Ngo-2019, umthamo wokungenisa wepetroleum coke e-China wawuzizigidi ezisisi-8.267 zeetoni, kwaye ngo-2020, yayiziitoni ezizizigidi ezili-10.277, ukonyuka kwe-24.31% xa kuthelekiswa no-2019.
Ngo-2020, isixa-mali sokungeniswa kwePetroleum coke e-China sasiyi-USd 1.002 yebhiliyoni, yehla nge-36.66% unyaka nonyaka. Ngo-2020, umthamo wokungenisa i-petroleum coke ufikelele kwincopho yayo, kodwa ixabiso lokungenisa i-petroleum coke lehlile. Njengoko uqoqosho lwehlabathi luye lwabethwa kanobom sisibetho se-COVID-19, ixabiso lepetroleum coke kwintengiso yezizwe ngezizwe liye lehla, elithe lakhuthaza ukungeniswa kwepetroleum coke eTshayina kwaye lonyusa umthamo wokungenisa wepetroleum coke, kodwa yanciphisa imali yokungenisa elizweni.
Ngokwedatha ye-China Customs, ukuthunyelwa ngaphandle kwe-petroleum coke yase-China kubonise indlela ehlayo, ngakumbi ngo-2020 ngenxa yempembelelo ye-COVID-19, ukuthunyelwa kwepetroleum coke yase-China kwehle kakhulu, ngo-2020, ukuthunyelwa ngaphandle kwe-petroleum coke kwehle ukuya kwi-1.784 yezigidi zeedola, a unyaka nonyaka ukwehla nge-22.13%; Ixabiso lokuthumela ngaphandle laliyi-459 yezigidi zeedola, phantsi kwe-38.8% ngonyaka.
D. Indlela yophuhliso yoshishino lwepetroleum coke
Ekuhambeni kwexesha, imarike yepetroleum coke isagcwele ukungaqiniseki okuninzi, kwaye ipateni kunye nepateni yemfuno yepetroleum coke isajongene nemingeni eyongezelelekileyo. Ukusuka kwimbono yesakhiwo somthamo, kwixesha elifutshane, ngenxa yokuhanjiswa okucothayo kwe-oyile eseleyo ye-hydrogenation umthamo, ukulibaziseka kokunikezelwa kwesixhobo sokupheka kuseyona ndlela iphambili. Ngexesha elide, icala lokubonelela nge-petroleum coke nalo liya kuthintelwa kukhuseleko lokusingqongileyo, imigaqo-nkqubo kunye nezinye izinto, kwaye kuya kuqhubeka kukho ubugcisa obutsha kunye nezinto ezithatha indawo ezihambelana nokusingqongileyo. Umgaqo-nkqubo wokukhuselwa kokusingqongileyo ngokuthe ngcembe usiba yinto eqhelekileyo, kwaye imveliso ayinakuthintelwa ukufezekisa ukukhutshwa kwe-ultra-low. Ngokuphuculwa kwezixhobo zokhuselo lokusingqongileyo kwamashishini, impembelelo yomgaqo-nkqubo wokhuselo lokusingqongileyo kwimarike iya kuba buthathaka, kwaye nefuthe lonikezelo lwemarike kunye nobudlelwane bemfuno kunye nexabiso lokuthengwa kwempahla ekrwada liya kunyuswa.
Icala lemfuno, i-petroleum coke ezantsi ishishini liya kuqhubeka nokuzisa imingeni eyahlukeneyo yezoqoqosho, imiba yomgaqo-nkqubo, amashishini e-aluminiyam ye-electrolytic ngoku ixhomekeke kwi-alumina, ixabiso lombane, ixabiso liphezulu ukuba libe nenzuzo yokuthetha ngayo, ngoko ke iinkampani ze-aluminium zexesha elizayo zineenkampani ezipheleleyo ze-aluminium. inzuzo enkulu, njengoko i-aluminiyam yemarike yobeko iya kutshintsha ngokucothayo, embindini iya kuthi ngokuthe ngcembe idlulise umthamo, Iya kuchaphazela ipateni kunye nophuhliso lwemarike ye-anode ebhakiweyo kunye nemarike yekhabhoni kwixesha elizayo.
Ngexesha eliphakathi kunye nexesha elide, i-macroeconomic environment, imigaqo-nkqubo yoshishino lwelizwe, isakhiwo sokubonelela ngemveliso, utshintsho lwe-inventory, amaxabiso ezinto eziluhlaza, ukusetyenziswa kwezantsi, iimeko eziphuthumayo, njl. Ke ngoko, amashishini kufuneka ahlalutye imeko yeshishini le-petroleum coke, afunde ngakumbi malunga nemigaqo-nkqubo efanelekileyo ekhaya nakwamanye amazwe, aqikelele ulwalathiso lophuhliso lwexesha elizayo lwentengiso yepetroleum coke, ukuphepha kwangexesha imingcipheko, ukubamba amathuba, utshintsho olungexesha kunye nolutsha, lixesha elide. isisombululo.
