Coal Tar Pitch (CTP) and Calcined Petroleum Coke (CPC) are the main raw materials used for anode fabrication. Over the last decades, the metallurgical coke oven technology has been improved to minimize the environmental emissions and increase the coke oven productivity, and the coal tars used as raw material for pitch production have been affected by this change. At the same time the CPC quality has changed due to changes in crude oil qualities, and an increase of isotropic coke, and a dramatic increase of Sulphur and impurities including Vanadium is observed.
Hydro has followed these raw material changes and studied the effect on the interaction between coke and binders by applying a sessile drop measurement wetting test. The results are reviewed for the anode production process. Results will be presented also for coke blends of isotropic and anisotropic coke.
