Based upon the simple model of particles which keep their diameters almost constant during reaction with the gas flowing in the fluidized bed, and applying the exit age-distribution functions obtained in Part I, equations for the conversion of product particles were derived.

✦ Synopsis
Experimental data from gas-solid fluidized reactor systems are analysed on the basis of the theoretical treatment of Parts I and II. The following systems are treated : (a) Roasting of pyrrhotite and zinc blende particles with uniform size. (b) Roasting of zinc blende concentrate with wide distribution of size. (c) Distillation of sulphur with two-stage fluidized reactor. (d) Nitrogenation of calcium carbide.
Close agreement between theory and experiment is obtained.

The distribution of residence times of solid particles is examined in fluidized beds at steady state with continuous feed and discharge of solids, both for beds consisting of a single particle size and for beds consisting of a wide spectrum of particle sizes. The mean age (residence time in bed) of
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 a
The performance of solid-gas reactions in a fluidized bed reactor is simulated by a model based on information of the bubble behavior and the movement of solids. The computational procedures for the cases in which the solids are fed continuously to the bottom of the bed and withdrawn from the top, a
## Abstract Experiments were performed to study the hydrodynamics of a cocurrent three‐phase fluidized bed with liquid as continuous phase. Based on the 209 experimental data (with four liquid systems and five different particles) along with 115 literature data from six different sources on minimum
A liquid-solid fluidized bed reactor was used to carry out sulfate reduction with a mixed culture of sulfate reducing bacteria. The bacteria were immobilized on porous glass beads. Stable fluidized bed operation with these biofilm-coated beads was possible. The low specific gravity of the hydrated b
