| Abstract Scope |
Bulk density is a key property of anode grade petroleum cokes used in aluminum smelting and many studies have been undertaken on this parameter. These include previous work by BP that showed how particle shape could be modified by using different crushing technologies, and that changing shape parameters (i.e. sphericity and convexity) has a significant influence on coke bulk density. A single coke was used in this initial study to keep coke porosity relatively constant. This work has now been extended to include the testing of a number of different petroleum cokes (calcined using diverse calcining technologies) and anode butt samples to introduce variation in sample porosity as well as shape. The test results were used to develop a simple model of the factors that impact bulk density, and the comparative influence of particle shape and porosity on coke bulk density was determined. |
