The process of calcining coke in a rotary kiln is always associated with both inevitable and controlled coke losses. Inevitable losses occur due to both demoisturization and devolatilization, i.e. such losses are a function of the properties of a coke source. Controlled losses are a function of the following: calcination parameters, the condition of the exhaust gas duct system, and …

Petroleum coke calcining is a three step process, including drying, devolatization and densification. The coke calcining process is a time-temperature function, conducted in an oxygen deficient atmosphere.
The coke calcining process is a time-temperature function, conducted in an oxygen deficient atmosphere. Important control variables are heating rate, air addition rate and final calcination temperature. To obtain the calcined coke properties required by the carbon and graphite industries, the coke must be subjected to temperatures of 1150-1350 ...
Calcined petroleum coke (CPC) is produced when raw coke is calcined. Calcination is the process of heating materials at high temperatures. In this process, remove the moisture content from the raw coke. Its appearance is a black or dark gray honeycomb structure, which belongs to the easily graphitizable carbon class.
The calcination process of petroleum coke is a critical step in transforming raw petcoke into a high-quality, high-carbon product suitable for various industrial applications. The process involves heating the petcoke to high temperatures, removing volatile matter and impurities, and cooling the resulting calcined petroleum coke.
Green petroleum coke (GPC) is a byproduct of petroleum refinery, and can undergo a thermal upgrade process (calcination) to transform into calcined petroleum coke (CPC), which is more suitable for anode production.
Calcination TimeThe duration of the calcination process affects the extent to which the petroleum coke undergoes structural changes. Extended calcination times can enhance the graphitization process and reduce the material's porosity. Therefore, the absorption rate of CPC is influenced by how long the material is exposed to high temperatures.
