Delayed coker design and project execution

The coke can be either fuel or anode grade, depending on the feedstock characteristics. Naphthas, light gasoils and heavy gasoils produced from thermal processes, like delayed coking, require considerable hydrotreating before further use as either feed to downstream process units or as a final product (diesel) in the case of the light gas oils produced.

Aluminium for Future Generations – Anode Production

Prebake anodes are produced in an area of the smelter called a “green mill” and are made from petroleum coke, pitch and recycled anode butts (the ends of the consumed anodes remaining at the end of their life) returned from the smelting process. These materials are mixed together in heated containers and poured into moulds.

Effects of Coke Calcination Level on Pore Structure in …

Formation of these elongated pores may be attributed to coke shrinkages during the anode baking process, which may develop cracking in the anode under cell operations. More small or medium rounded pores with pore size range of 10-400 μm emerge in the anodes with coke calcination temperatures of 900°C, 1000°C and 1100°C, which may be generated due to release of volatiles from …
