Abstract:

The aim of the present study was to establish the optimal operating dynamic parameters in fluidized bed for the sodium clay particles and pillared clay particles. In order to determine the influence of the clay particles on the structure of the fluidized bed, the conditions in which the incipient fluidization appears were determined depending on the: nature, diameter and density of the material, gas velocity and fixed bed height. Experimentally the minimum fluidization velocity, the minimum pressure drop and bed porosity were determined. Correlation relations were established in order to approximate the minimal error for the experimental results.

Keywords:

fluidized bed, clay particle, pressure drop, minimum fluidization velocity.
