摘要：

The model developed by Ocone et al.(1) to describe particle distribution in a flowing gas-particle mixture was modified to include a counter-diffusive solid concentration term and applied to fluid cracking catalyst in a circulating fluidized bed. Comparison of the local solid flux distribution predicted by the new model with experimental data published previously by Bodelin et al.(2) showed very good agreement.
