Petroleum coke nthawi zambiri imakhala ndi njira zinayi zotsatirazi:
Malingana ndi njira yopangira, ikhoza kugawidwa mu coke yaiwisi ndi coke yophika.
Zakale zimachokera ku coke tower ya coking unit yochedwa, yomwe imadziwikanso kuti coke yaiwisi, yomwe imakhala ndi zinthu zowonongeka komanso zimakhala ndi mphamvu zochepa;

Malinga ndi mlingo wa sulfure okhutira
Itha kugawidwa mu coke ya sulfure yapamwamba (yochuluka ya sulfure ndi yoposa 4%), coke ya sulfure yapakati (sulfure 2% ~ 4%) ndi coke ya sulfure yochepa (sulfure imakhala yotsika kuposa 2%). .
Sulfure zili mu coke makamaka zimadalira sulfure zomwe zili mu mafuta osaphika.Pamene sulfure ikuwonjezeka, khalidwe la coke limachepa, ndipo kugwiritsidwa ntchito kwake kumasintha moyenera.

Malinga ndi ma microstructure osiyanasiyana
Ikhoza kugawidwa mu siponji coke ndi singano coke.Yoyamba imakhala ndi porous ngati siponji, yomwe imadziwikanso kuti coke wamba.Yotsirizirayi ndi yowuma komanso yamtundu, yomwe imadziwikanso kuti coke yapamwamba;
Ndi yosiyana kwambiri ndi coke ya siponji mu katundu, ndipo ili ndi makhalidwe a kachulukidwe kwambiri, chiyero chapamwamba, mphamvu zambiri, sulfure yochepa, kuchuluka kwa ablation, kutsika kwa kutentha kwapakati komanso kukana kwabwino kwa kutentha;mu matenthedwe madutsidwe, madutsidwe magetsi, maginito madutsidwe ndi Onse ali zoonekeratu anisotropy optically;ma pores ndi aakulu ndi ochepa, ozungulira pang'ono, pamwamba pake osweka amakhala ndi mawonekedwe omveka bwino, ndipo kukhudza kumayikidwa mafuta.Coke ya singano imapangidwa makamaka kuchokera ku mafuta otsalira okhala ndi ma hydrocarbons onunkhira komanso zochepa zonyansa zomwe si hydrocarbon.

M'njira zosiyanasiyana
Itha kugawidwa mu singano coke, projectile coke kapena spherical coke, siponji coke ndi ufa coke.
(1) Coke ya singano: Ili ndi mawonekedwe owoneka ngati singano ndi kapangidwe ka fiber, ndipo imagwiritsidwa ntchito makamaka ngati ma elekitirodi amphamvu kwambiri komanso apamwamba kwambiri a graphite popanga zitsulo.
(2) Sponge coke: sulfure wambiri, chinyezi chambiri, pamwamba pake komanso mtengo wapamwamba.
(3) projectile coke kapena spherical coke: mawonekedwe ake ndi ozungulira, m'mimba mwake ndi 0.6 ~ 30mm, ndipo madzi ndi otsika chifukwa chosalala pamwamba.Kawirikawiri, amapangidwa kuchokera ku mafuta otsalira a sulfure ndi apamwamba-asphaltene, omwe angagwiritsidwe ntchito popanga magetsi, simenti ndi mafuta ena a mafakitale.
(4) Powder coke: Amapangidwa ndi njira yopangira ma radial fluidization coking, ndipo tinthu tating'onoting'ono timakhala ndi kuchuluka kwamafuta ochulukirapo (m'mimba mwake 0.1 ~ 0.4mm) ndipo sangathe kugwiritsidwa ntchito mwachindunji pokonzekera ma elekitirodi ndi mafakitale a kaboni.
