A catalyst having spherical particles of Dp = 50 microns and ρs = 1.65 g/cm3 is to be used to contact a hydrocarbon vapour in a fluidized reactor at 900 ºF, 1 atm pressure. At rest the bed has a porosity of 0.35 and a height of 3 ft. At operating conditions, the fluid viscosity is 0.02 centipoise and its density is 0.21 lb/ft3. Determine the superficial gas velocity necessary to fluidize the bed, the velocity at which the bed would begin to flow with the gas, and the extent of bed expansion when the gas velocity is the average of the velocities previously determined. The porosity at minimum fluidization velocity is 0.42. Does aggregative of particulate fluidization occur ?
