Kunni and Levenspiel Model

First-order catalytic reaction of A → B with -r'''_A = k'''C_A in a BFB reactor.
Reactant gas (c_A0 = 100 mol m^-3) passes upward through a 2 m diameter fluidized bed (ε_mf = 0.5, alpha = 0.33 and D = 20x10^-6 m² s^-1) containing solid catalyst particles (ρ_s = 2000 kg m^-3).
