Determine the minimum fluidizing velocity of the catalyst for 1500kg of the catalyst in a tubular fluid bed reactor with a radius of 0.5m, given that the optimum conversion reaction occurs when the bed volume is 1.64 the volume of the catalyst particles. The fluid density and viscosity are 1000kg/m3 and 3.9mPas, respectively, while the particle density is 3000kg/m3. Part 3 For the same particles, what would happen if an upward flowing fluid (=950kg/m3,=0.0015 Pa.s) at 5.5mm/s is passed through the bed? If the catalysts are fluidized, what would be the mass fraction of the catalyst particles that is entrained (i.e. moving upwards and out of the reactor with the fluid flow)? The catalyst sphericity is 1 . Hint: Volume distribution in Table 1 can be converted into mass distribution. S
