✦ Synopsis


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.

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 distribut

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
