✦ Synopsis

intersections when the values of (B) and (\alpha^{\prime}) are higher than 1 , i.e. when the deactivation is so
high that the functional availability of the reactor volume is not completely achieved.

The maximum values of (z_{A P} / z_{A M}) for (B) and (\alpha^{\prime}) less than 1 are approximately located in the range of (k_{0} \tau_{L}) from 1 to 2 . This result shows the different role of the operating parameters on the two models. The main result from Figs. (1 c) and (2 c) is that the knowledge of the solids R.T.D.F. is relevant in the design of fluidized bed reactors with a continuous solids feed: actually, variations up to (30 %) in the conversion degree may be expected because of the solids-1iquid backmixing.

Particle Peclet numbers ranging from 0.056-O. 198 were calculated from tracer response measurements in a three-phase fluid&d bed consisting of air, water, and alginate beads. Diffusion of the calcium chloride tracer into the beads was measured and found to follow Fick's Law. If unaccounted for, intr
