Combustion of petroleum coke dust as a partial substitute
Delayed petroleum coke is calcined in an internally-fired vertical shaft kiln. A downwardly-moving bed of green coke is preheated in the top of the kiln by rising combustion gases, then heat soaked at calcining temperatures in the intermediate section of the kiln, and finally cooled by recycle gas moving upwardly from the lower part of the kiln.trend of % sulphur in the calcined coke with respect to GPC blending. The variations occurred due to the coke used based on its inventory and availability. Carbon departments mon-itor and evaluate the changes in all quality parameters of calcined coke and adjust accordingly in order to achieve anode quality consistently.

What is Petroleum Coke or Petcoke? Its Types, Applications,
7. Production Process: Petroleum Coke: Petcoke is a byproduct of the oil refining process, specifically from the coking of residual oil. Coal: Coal is mined from underground or surface mines and undergoes various processing steps before it is used as a fuel. The major differences between coal and petroleum coke are reproduced below in Table 2.Petroleum coke calcination is the primary process for carbon anode preparation. The quality of calcined petroleum coke (CPC) is directly related to the properties of carbon an-ode, which is the key factor affecting the stable opera-tion of aluminum electrolysis production [1, 2].

Carbon Anode Raw Materials—Where Is the Cutting Edge?
The CTP (coal tar pitch) and CPC (calcined petroleum coke) raw materials used for anode production are both manufactured from byproducts of other industries making the aluminum industry dependent on others for two key raw materials. Despite this, the industry has made steady improvements in anode quality and performance over the 0Share. Petroleum coke, also known as petcoke, is a solid carbon-rich material that is produced during the refining of crude oil. It is typically a byproduct of the refining process, and is produced when heavy crude oil is processed to produce gasoline, diesel fuel, and other refined products.
