Calcined petroleum coke uses
Calcined petroleum coke (CPC) plays a key role in a variety of industrial processes. It is produced from raw petroleum coke (CPC) by a high-temperature calcination process.
It is extracted from raw petroleum coke (RPC) by a high-temperature calcination process, which removes volatile hydrocarbons and improves the density and electrical properties of coke.
This process can remove volatile hydrocarbons and increase the density and conductivity of coke. Below is a summary of the main uses of calcined petroleum coke.
