A packed-bed reactor is injected with a tracer. The pulse is injected into the bed about 4 particle diameters from the entrance, which is not perfect. The variance in the injection is = 15 s 2. The variance at the measuring point 3 m downstream is = 50 s 2. The superficial velocity is 0.01 m/s. (a) Calculate the dispersion coefficient (b) Calculate the conversion for a first-order reaction in which k = 0.02 s -1
