Uhlobo lwe-coke olutholwe ngokubambezeleka ukupheka amafutha asele.Ingqikithi iyifomu lekhabhoni elenziwe ngokwengxenye.Imnyama ngombala futhi i-porous, ngendlela yama-granules ahlanganisiwe, futhi ayikwazi ukuncibilika.Ukwakheka kwe-elemental ikakhulukazi ikhabhoni, ngezikhathi ezithile equkethe inani elincane le-hydrogen, i-nitrogen, isulfure, umoya-mpilo kanye nezinye izakhi zensimbi, futhi kwesinye isikhathi ezinomswakama.Isetshenziswa kabanzi kwezensimbi, embonini yamakhemikhali nakwezinye izimboni njengama-electrode noma izinto zokusetshenziswa zokukhiqiza imikhiqizo yamakhemikhali.

I-morphology ye-petroleum coke iyahlukahluka ngenqubo, izimo zokusebenza kanye nohlobo lokuphakelayo.I-petroleum coke ekhiqizwa endaweni yokusebenzela ye-petroleum coke ibizwa ngokuthi i-coke eluhlaza, equkethe ukuguquguquka okuthile kwezinhlanganisela ze-hydrocarbon ezingakhabhoni.I-coke eluhlaza ingasetshenziswa njenge-fuel-grade petroleum coke.Ama-Electrode asetshenziswa ekwenzeni insimbi adinga ukubalwa ezingeni lokushisa eliphezulu ukuze kuqedelwe i-carbonization kanye nokunciphisa izinto eziguquguqukayo zibe ncane.

Ukubukeka kwe-coke ekhiqizwa ezindaweni eziningi zokusebenzela ze-petroleum coke i-black-brown porous solid block irregular block.Lolu hlobo lwe-coke lubizwa nangokuthi i-sponge coke.Uhlobo lwesibili lwe-petroleum coke enekhwalithi engcono lubizwa ngokuthi i-needle coke, efaneleka kakhulu kuma-electrode ngenxa yokumelana kwayo okuphansi kagesi kanye ne-coefficient yokwandisa ukushisa.Uhlobo lwesithathu lwe-hard petroleum coke lubizwa ngokuthi i-shot coke.Le coke imise okwe-projectile, inendawo encane futhi akulula ukuyipheka, ngakho ayisetshenziswa kakhulu.

I-petroleum coke ithatha uwoyela osindayo noma amanye uwoyela osindayo ngemuva kokukhishwa kwe-distillation kawoyela ongahluziwe njengezinto ezingavuthiwe, futhi idlula kushubhu lesithando somlilo esingu-500 ℃ ± 1 ℃ esithandweni sokushisa ngezinga lokugeleza okuphezulu, ukuze ukuqhekeka nokusabela kwe-condensation kwenziwe embhoshongweni we-coke, bese i-coke ipholiswa isikhathi esithile.Ukupheka nokuhlobisa kukhiqiza i-petroleum coke.
