| Abstract Scope |
An ongoing objective of BP Coke’s technical support is to better understand fundamental coke properties and links to anode performance. This knowledge is then applied to improve coke value for Customers. Calcined coke microstructure and porosity are properties known to influence key anode properties such as Baked Apparent Density. Assessing coke microstructure and porosity using conventional tests such as optical microscopy and mercury porosimetry is time consuming, complex, and does not provide well quantified structural detail. 3D X-ray techniques are now capable of quantifying internal coke and anode physical structures. For example, micro X-Ray Computed Tomography has been used by others to assess anode core anisotropy and cracking. This paper outlines 3D X-ray microscopy undertaken to study inconsistencies between expected coke particle internal structures based on external appearance, and the actual internal structures. This is important when visually categorizing coke types. Other potential applications of the microscopy technique are outlined. |
