Mtundu wa coke wopezedwa mwa kuchedwa kuphika mafuta otsalira.Chofunikira chake ndi mawonekedwe a carbon graphitized pang'ono.Ndi wakuda mumtundu ndi porous, mu mawonekedwe a granules zaunjika, ndipo sangathe kusungunuka.Zomwe zimapangidwira zimakhala ndi carbon, nthawi zina zimakhala ndi hydrogen, nitrogen, sulfure, mpweya ndi zinthu zina zachitsulo, ndipo nthawi zina zimakhala ndi chinyezi.Amagwiritsidwa ntchito kwambiri muzitsulo, makampani opanga mankhwala ndi mafakitale ena monga ma electrode kapena zipangizo zopangira mankhwala.

Mapangidwe a petroleum coke amasiyana malinga ndi momwe amagwirira ntchito, momwe amagwirira ntchito komanso momwe amadyera.Mafuta a petroleum coke omwe amapangidwa kuchokera ku petroleum coke workshop amatchedwa green coke, yomwe imakhala ndi zinthu zina zosasunthika za mankhwala a hydrocarbon osatulutsidwa.Coke wobiriwira amatha kugwiritsidwa ntchito ngati mafuta amafuta amafuta.Ma elekitirodi omwe amagwiritsidwa ntchito popanga zitsulo amafunikira calcined pa kutentha kwakukulu kuti amalize kutulutsa mpweya ndi kuchepetsa zinthu zosasinthika kukhala zochepa.

Maonekedwe a coke omwe amapangidwa m'mashopu ambiri a petroleum coke ndi block yakuda-bulauni yolimba yosakhazikika.Coke wotere amatchedwanso sponge coke.Mtundu wachiwiri wa petroleum coke wokhala ndi khalidwe labwino umatchedwa singano ya singano, yomwe ili yoyenera kwa ma electrode chifukwa cha kuchepa kwake kwa magetsi komanso mphamvu yowonjezera kutentha.Mtundu wachitatu wa coke wolimba wa petroleum umatchedwa shot coke.Coke iyi imapangidwa ngati projectile, ili ndi malo ang'onoang'ono pamwamba ndipo sikophweka kuphika, choncho siigwiritsidwa ntchito kwambiri.

Petroleum coke imatenga mafuta olemera kapena mafuta ena olemera pambuyo pa kusungunula mafuta osakanizika ngati zopangira, ndikudutsa mu chubu la ng'anjo ya 500 ℃ ± 1 ℃ yotentha ng'anjo yotentha kwambiri, kotero kuti ming'alu ndi condensation zimachitika mu nsanja ya coke, ndiyeno kolokoyo imakhazikika kwa nthawi inayake.Kuphika ndi kuphika kumapanga mafuta a coke.
