A. gulu la petroleum coke
Petroleum coke ndi yakuda mafuta distillation adzakhala kuwala ndi katundu kulekana mafuta kulekana, lolemera mafuta ndiyeno kudzera m`kati otentha akulimbana, kusandulika mankhwala, kuchokera maonekedwe, coke kwa osasamba mawonekedwe, kukula kwa wakuda chipika (kapena particles), zitsulo luster, coke particles ndi porous dongosolo, chachikulu chinthu zikuchokera mpweya, Gwirani 80wt%. (wt = kulemera)
Malinga ndi processing njiraakhoza kugawidwa mucoke yaiwisindikuphika koka. Zakale zimapezedwa ndi nsanja ya coke ya chipangizo chochedwa coking, chomwe chimadziwikanso kuticoke choyambirira; Yotsirizirayi imapangidwa ndi calcination (1300 ° C), yomwe imadziwikanso kuticalcined coke.
Malinga ndi sulfure okhutira, akhoza kugawidwa kukhalahigh sulfure coke(Sulfure zili zambiri kuposa4%), coke wa sulfure wapakati(sulfure zili ndi2% -4%) ndiotsika sulfure coke(Sulfure ndi yochepa kuposa2%).
Malinga ndi ma microstructure osiyanasiyana, akhoza kugawidwa kukhalasponge cokendisingano coke. Kale porous monga siponji, amadziwikanso kuticoke wamba. Yotsirizirayo imakhala ngati fibrous, yomwe imadziwikanso kuticoke wapamwamba kwambiri.
Malinga ndi mitundu yosiyanasiyanaakhoza kugawidwa musingano coke, projectile coke or coke yozungulira, sponge coke, unga wa kokamitundu inayi.
B. kutulutsa mafuta a coke
Mafuta ambiri a petroleum coke omwe amapangidwa ku China ndi a low sulfur coke, omwe amagwiritsidwa ntchito kwambirikusungunuka kwa aluminiyumundikupanga graphite.Zinazo zimagwiritsidwa ntchito makamakazinthu za carbon, mongaelectrode ya graphite, anode arc, yogwiritsidwa ntchitozitsulo, zitsulo zopanda chitsulo; Zinthu za silicon za carbonized, monga zosiyanasiyanamagudumu akupera, mchenga,mchenga pepalandi zina; Commercial calcium carbide yopanga ulusi wopangira, acetylene ndi zinthu zina; Itha kugwiritsidwanso ntchito ngati mafuta, koma popanga mafuta, imayenera kugwiritsa ntchito mphero yamagetsi kuti igwiritse ntchito pogaya kwambiri. Pambuyo popanga ufa wa coke kupyolera mu zipangizo, ukhoza kuwotchedwa. Ufa wa coke umagwiritsidwa ntchito makamaka ngati mafuta m'mafakitale ena agalasi ndi zomera zamadzi a malasha.
Malinga ndi National Bureau of Statistics, kutulutsa kwa mafuta aku China mu 2020 kunali matani 29.202 miliyoni, kukwera 4.15% chaka chilichonse, ndipo kuyambira Januware mpaka Epulo 2021, kutulutsa kwamafuta aku China kunali matani 9.85 miliyoni.
Kupanga mafuta a petroleum coke ku China kumapezeka makamaka kummawa kwa China, kumpoto chakum'mawa kwa China ndi South China, komwe kumapangidwa kwambiri kummawa kwa China. M'chigawo chonse chakum'maŵa kwa China, chigawo cha Shandong chili ndi mafuta ambiri a petroleum coke, omwe anafika matani 10.687 miliyoni mu 2020. Kutulutsa kwa petroleum coke m'chigawo cha Shandong sikungoyambira kum'mawa kwa China, komanso kumayambira m'madera onse ndi mizinda ku China, ndipo kutulutsa kwa mafuta a petroleum coke ndipamwamba kwambiri kuposa mizinda ina.
C. Petroleum coke import and export
China ndi m'modzi mwa omwe amaitanitsa mafuta a petroleum coke, omwe makamaka amachokera ku United States, Saudi Arabia ndi Russia. Malinga ndi deta ya China Customs, kuchuluka kwa mafuta a petroleum coke ku China kuchokera ku 2015 mpaka 2020 kunawonetsa kukwera. Mu 2019, kuchuluka kwa petroleum coke ku China kunali matani 8.267 miliyoni, ndipo mu 2020, kunali matani 10.277 miliyoni, kuwonjezeka kwa 24.31% poyerekeza ndi 2019.
Mu 2020, kuchuluka kwa Petroleum coke ku China kunali USD 1.002 biliyoni, kutsika ndi 36.66% pachaka. Mu 2020, kuchuluka kwa mafuta a petroleum coke kunafika pachimake, koma mtengo wa petroleum coke unatsika. Pomwe chuma chapadziko lonse lapansi chakhudzidwa kwambiri ndi mliri wa COVID-19, mtengo wamafuta amafuta pamsika wapadziko lonse watsikanso, zomwe zalimbikitsa kuitanitsa kwa petroleum coke ku China ndikuwonjezera kuchuluka kwa mafuta a petroleum coke, koma kumachepetsa kuchuluka komwe kumachokera.
Malinga ndi kuchuluka kwa China Customs, kugulitsa kwa petroleum coke ku China kudawonetsa kutsika, makamaka mu 2020 chifukwa cha zovuta za COVID-19, kutumizidwa kwa petroleum coke ku China kudatsika kwambiri, pofika 2020, kutumizidwa kwa petroleum coke ku China kudatsika mpaka 1.784 miliyoni DOLLARS, pachaka 2 pa 2. Mtengo wogulitsa kunja unali $ 459 miliyoni, kutsika ndi 38.8% chaka ndi chaka.
D. Chitukuko chamakampani a petroleum coke
M'kupita kwa nthawi, msika wa petroleum coke udakali wodzaza ndi zokayikitsa zambiri, ndipo njira yoperekera ndi kufunikira kwa petroleum coke ikukumana ndi zovuta zambiri. Kuchokera pamalingaliro a kapangidwe ka mphamvu, kwakanthawi kochepa, chifukwa chakuchepa kwapang'onopang'ono kwa otsalira amafuta a hydrogenation, kuchedwa kwa chipangizo cha coking kukadali njira yayikulu. M'kupita kwa nthawi, mbali yopereka mafuta a petroleum coke idzaletsedwanso ndi chitetezo cha chilengedwe, ndondomeko ndi zinthu zina, ndipo padzakhalabe matekinoloje atsopano komanso zowonjezera zachilengedwe. Mfundo yoteteza zachilengedwe pang'onopang'ono ikukhala yachilendo, ndipo kupanga sikungangowonjezera kutulutsa mpweya wochepa kwambiri. Ndikusintha kwa zida zamabizinesi zomwe zimateteza chilengedwe, zotsatira za mfundo zoteteza chilengedwe pamsika zidzachepetsedwa, ndipo chikoka cha kupezeka kwa msika ndi ubale wofunikira komanso mtengo wogula wazinthu zamabizinesi udzakulitsidwa.
Kufuna mbali, mafuta coke kumunsi makampani adzapitiriza kuyambitsa mavuto osiyanasiyana azachuma, mfundo mfundo, electrolytic zotayidwa mabizinezi panopa pansi aluminiyamu, mtengo magetsi, mtengo ndi mkulu kukhala ndi phindu kulankhula za, kotero makampani tsogolo zotayidwa ndi unyolo wathunthu makampani ali ndi phindu lalikulu, monga zotayidwa msika masanjidwe pang'onopang'ono kusintha, chapakati adzakhala pang'onopang'ono kusamutsa mphamvu msika, Zidzakhudza chitukuko cha m'tsogolo anode msika.
Pazaka zapakati komanso zazitali, malo azachuma, mfundo zamakampani adziko lonse, kapangidwe kazinthu, kusintha kwazinthu, mitengo yamafuta, kutsika kwamadzi, zadzidzidzi, ndi zina zotero, zitha kukhala zomwe zikuyambitsa msika wamafuta a coke pamagawo osiyanasiyana. Chifukwa chake, mabizinesi akuyenera kusanthula momwe zinthu ziliri pamakampani a petroleum coke, kuphunzira zambiri za mfundo zoyenera kunyumba ndi kunja, kuneneratu zamtsogolo za msika wamafuta amafuta a coke, kupewa ngozi panthawi yake, kugwiritsa ntchito mwayi, kusintha kwakanthawi komanso luso, ndi yankho lanthawi yayitali.
