2/6/1992· Raw petroleum coke, that is, petroleum coke that has not been calcined, usually has a volatile matter content of between about 6 and 14 percent. The volatile matter is typically removed by heating the raw petroleum coke in a calciner to temperatures of between about 1200° C. and about 1400° C. Occasionally, calcining temperatures as high as 1500° C. may be employed.

Utilization of petroleum coke in the rejuvenating Nigerian metallurgical industry is currently satisfied by importation from more industrialized nations of the world such as the USA, Brazil and Venezuela where delayed coking plants operate and grow in nuer. The
Petroleum coke Wikipedia Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes.Petcoke is the coke that, in particular, derives from a final cracking
North American production of petroleum coke or petcoke, as it’s commonly known, has been steadily increasing since the late 80s. But innovations in bitumen extraction have allowed petcoke production to shoot up in recent years, and U.S. exports of petcoke have risen by the barrel load: 184 million barrels in 2012, to be precise.
Calcined petroleum coke and graphite are both commer- cially available products. In general, the calcined petro- leum coke used here was a carbonaceous material which had been heat-treated at approximately 1300~ Various grades of coke
Delayed petcoke is petroleum coke produced by the delayed coking process, which is a semi-continuous batch process that can be carried out in one of three ways: ultimate, once-through or intermediate coking. 1 The first delayed coker was built by Standard Oil …
