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 process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units termed coker units . [1] (

Manufacture - EPM Group

After crushing and sorting calcined petroleum coke is sent to the batch preheaters for premixing and heating to target temperature, then it goes to the batch blender, where it is mixed with coal tar pitch generating coke-pitch blend. The mass goes to the vibrating press and takes the shape of the anode block with the target dimensions.
