Question

A first order internal diffusion limited reaction, A ? B is carried out in a packed bed reactor. Pure reactant A is flowing at 3 m³/s into the reactor which is packed with spherical catalyst with particle density of 2800 kg/m³ and internal surface area of 280,000 m²/kg. The catalyst bed has porosity of 0.5. The reactor is of cylindrical shape with 1.5 m diameter and 4 m length. The reaction rate constant is 3.5 x 10?? m/s and the $k_{ca}$ is 4 s?¹. Determine the diameter of the catalyst particles that is required to be used in this reactor in order to yield a conversion of 80% for reactant A.
