Petroleum coke - Wikipedia

7.6 Petroleum Coke. When petroleum is refined, there are residues left behind that are processed into coke to yield either delayed coke or fluid coke. In the delayed coking process, various petroleum feedstocks, including vacuum and pyrolysis residues and decant oils heated to about 450°C are pumped into a drum and held for 24 hours (Adams, 1997).
