Résumé

Prebaked anodes are produced from aggregates (calcined coke, recycled butts and anodes) and binder pitch. Good binding between aggregates and pitch results in dense anodes and has a direct impact on the electrical resistivity. The quality of coke and butts has a strong influence on anode properties. A comprehensive study of the physical and chemical interactions taking place during mixing allows a better understanding of the important factors and helps determine conditions that will lead to improved anode properties. The objective of this research is to characterize the surface properties of a calcined petroleum coke and butt particles and then relate them to their wettability by pitch. The wetting tests were carried out using the sessile drop method. Further investigations were carried out using SEM, FTIR, and XPS. In the article, the results of this study is presented and discussed.
