| Description/Abstract | The states of fluidization of FCC particles and two other types of particles with almost the same mean particle size, size distribution, and weight fraction of <44-..mu..m fines, but of higher density, were studied in beds 5.2-50 cm in internal diameter at superficial gas velocities up to about 60 cm/s.^The FCC particles fluidized smoothly, but the denser particles resulted in severe channeling in deep beds.^This channeling could be reduced by raising the superficial gas velocity to a level which, for the same particle-size distribution, depends on the density of the particles.^A good state of fluidity in a fluidized catalyst is possible except when the mean particle size is small and the size distribution is broad.^The density of the particles has a significant effect on their fluidity.^The fluidity of particles can be evaluated by plotting gas-holdup data, on the basis of recirculation theory for a bubble column. |
