FCC catalyst particles with a Sauter mean diameter of 350 microns, particle density of 2560 kg/m' and bulk density of 1250 kg/m are fluidized with air at ambient conditions in a column of 0.10 m diameter. Compute: (i) Voidage at minimum fluidization assuming it is the same as the voidage of a packed bed of the same material. [4] (ii) Settled bed height [3] (iii) Minimum fluidization velocity and compare it with the experimental value from the Figure given below. What is the percent difference? [3] NB: Assume that the sand sphericity is 0.8.
