2019-4-20 · 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 process—a thermo-based chemical engineering process that splits long chain hydrocarbons of
2. Petroleum coke The physical properties and the fuel analysis of a petroleum coke depend upon the crude oil and the manner in which it was processed. Petroleum cokes - including delayed coke, fluid coke, needle coke, shot coke, and flexicoke - are byproducts of solid residuals from the refining process.
2015-3-12 · Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Petroleum coke is usually calcined in a gas-fired rotary kiln or rotary hearth at high temperatures, around 1200 to 1450 °C, to remove moisture, drive off volatile matters, increase the density of the coke, increase physical

Notes: The process of “calcining” converts green coke to almost pure carbon, with a defined structure to produce carbon anodes for the aluminum industry.
The petroleum coke market primarily includes two types of petroleum coke: fuel grade coke and calcined coke. Fuel grade coke is expected to be the most dominant type of petroleum coke in terms of product segment in the near future. Fuel grade coke is primarily used in cement kilns and power plants owing to less cost and high calorific value.
