1. Incazelo yomkhiqizo:

I-coke ye-petroleum coke yesulfure ephakathi nendawo iyimikhiqizo kaphethiloli emnyama noma emnyama eqinile eqinile, ene-metallic luster, i-porous, yakhiwe nge-graphite encane ecwebezeliswe ibe yi-granular, ikholomu noma umzimba wekhabhoni onjengenaliti.Ingxenye ye-petroleum coke i-hydrocarbon, equkethe i-90 ~ 97% carbon, i-hydrogen 1.5 ~ 8%, futhi iqukethe i-nitrogen, i-chlorine, isulfure kanye nezinhlanganisela zensimbi ezisindayo.

I-Medium sulfur petroleum coke iwumkhiqizo kawoyela okhanyayo okhiqizwa i-pyrolysis yamafutha aluhlaza kuyunithi yokupheka ebambezelekile ekushiseni okuphezulu.Ukukhiqizwa kwe-petroleum coke cishe ku-25-30% wamafutha aluhlaza.Ukushisa kwayo okuphansi kumayelana namalahle izikhathi ezingu-1.5-2, okuqukethwe komlotha akukho ngaphezu kuka-0.5%, okuqukethwe okuguquguqukayo cishe ku-11%, ikhwalithi eseduze ne-anthracite.

2. izakhiwo kanye nokusetshenziswa:

I-coke ye-petroleum ye-sulphur ephakathi nendawo isetshenziselwa kakhulu ukwenza imikhiqizo ye-carbon, njenge-graphite electrode, i-anode arc, ukuhlinzeka ngensimbi, izinsimbi ezingenayo insimbi, i-aluminium smelting;Ukwenza imikhiqizo ye-silicon ye-carbonized, njengamasondo ahlukahlukene okugaya, isihlabathi, i-sand paper, njll.;Ukukhiqiza i-calcium carbide yokuhweba ukuze kukhiqizwe imicu yokwenziwa, i-ethyl esheshayo neminye imikhiqizo;Ingasetshenziswa futhi njengamafutha.
