Patent ·
OSTI ID:5250635
A fluidized-bed process and apparatus are described involving a vertical column containing 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 apertures. One section of each tray constitutes 80 to 95 percent 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.
