        Earlier fluidization correlations, based on experimental work with silica-sand beds, are briefly reviewed.  New data, observed during the fluidization of a typical fused-Fe Fischer-Tropsch catalyst, are presented.  This material was considerably more irregular than sharp sand. Typical mixtures, comprising components varying in size from 32-325 mesh, were investigated by using air and He as fluids.  It appeared that the new data agreed with the correlations based on the experimental work with sand beds when proper allowance was made for the greater irregularity of the particles.  The application of the correlations to process design is discussed on the basis of typical Fischer-Tropsch operating data.  The importance of correct evaluation of the physical properties of the reaction mixture was stressed in the application of the correlations.  In connection with process calculations, a simple semigraphic method for solving problems was proposed.
