Abstract Some characteristics are reported for the fluidization of an air‐microspheroidal catalyst system in a 16‐in.‐diameter bed equipped with baffles. The back‐mixing characteristics and retention‐time distributions of gas and solids, allowable gas and solids velocities, entrainment rate, and bed density are studied as functions of baffle design. It is shown that the use of baffles narrows the retention‐time spectrum and permits either concurrent or countercurrent flow while not seriously reducing gas or solids throughput or solids holdup.
