In the biomass gasification process to improve H; production performance, spherical particles of the Ni / VAl;O: catalyst with a size of 0.07 mm and a density of 3961 kg / m' are fluidized in a reactor with a diameter of 1.5 mand 2 m of m', using an air stream with a permanent gas mixture (density of 0.662 kg /m' and viscosity 2.80 x 10* Pa s). The volume occupied by the catalyst prior to fluidization is 5% of the total volume of the reactor. The vacuum fraction under the conditions of minimum fluidization is 0.45. a) Calculate the minimum fluidized bed height. L (m) = b) Calculate the pressure drop under minimum fluidization conditions. AP (kPa) = c) Calculate the minimum velocity for fluidization. V (m/s) = mf
