ABSTRACT:
A fluidized-bed process and apparatus involving a vertical column containing a plurality of perforated trays, each tray having a weir disposed on its upper surface to divide that surface into first and second sections, each of which has a plurality of apertures. One section of each tray constitutes 80 to 95% of the total tray surface area. Location of the weir on successive trays alternates from side to side of the column to provide for cross-flow of the fluidized material on the trays.
