Abstract
The effects of fines on the behavior of a fluidized-bed reactor have been investigated using a commercial catalyst for propylene ammoxidation. Experimental studies show that the catalyst powder agglomerates and that there exists a critical level of fines in the bed (around 30%) for which the fluid-bed behavior in terms of bed expansion, aeratability, and cluster size is optimum. The results also suggest that the dense phase should indeed be treated as two distinct phases: cluster and emulsion. A general mathematical model to account for these two phases is proposed.
