| Abstract: | An empirical approach has been developed to predict the total entrainment flux at different levels of freeboard height. The approach is based on the results of experimental investigations carried out in a 152 mm diameter column, with FCC as the feed powder. The powder was fluidized at superficial gas velocities of 0.2 m/s and 0.7 m/s. |
| Keywords: | Fluidized bed freeboard height elutriation rate constant total entrainment flux at bed surface elutriation rate constant at bed surface decay constant |
