Abstract (en)

[origin: WO9855426A1] A method is provided for the production of heat-treated carbon bodies in open-pit, ring furnaces. In the process green carbon bodies are packed with a carbonaceous particulate packing material containing as a constituent green petroleum coke in a blend with calcined and/or recycled petroleum coke particles. In the event the green petroleum coke is green delayed petroleum coke, the balance of the packing material is selected from calcined delayed petroleum coke, recycled packing material containing heat-treated delayed petroleum coke and/or mixtures of these; if the green petroleum coke used in the blend is green fluid petroleum coke, then the balance of the packing material is heat-treated calcined fluid coke. The invention further allows the utilization of low grade green delayed petroleum coke in the packing material.
