Petroleum Coke, or petcoke as it is sometimes commonly referred to, is a byproduct created in the refining process of heavy crude oil. During the distillation of the crude into the many various fractions and products (gasoline, diesel, fuel oil ...

An Introduction to Synthetic Graphite.

volatize, vaporize, or burn off any volatile components still remaining in the coke. Once the calcining process is completed the coke is known as calcined petroleum coke. The process and process parameters used to manufacture petroleum coke and calcined petroleum coke will be described in more detail below. 3. The Coking Process Schematic:
