Utilize the data given in Problem 4.5, assume the benzene hydrogenation reaction is zero order in benzene and first order in H2, and then calculate the Thiele modulus for the largest and smallest catalyst particles assuming all the Pd is in the mesopore. What is the Thiele modulus for the largest (500 μ) particles if all the Pd were dispersed in only the micropores? Should there be any concern about pore diffusion limitations for any of the three possibilities? Why?
