A gas phase reaction A + B → C + D is carried out in a packed-bed reactor. The reaction is first order in A and pseudo-zero-order in B. The total volumetric feed rate is 25 L/min, the initial pressure is 10 atm, the temperature is 223 C, and the pressure drop parameter a equals 0.01 kg 1. For an equal molar feed rate of A and B, the specific reaction rate is about 1.3 L/(kg*min). 1. (10 points) Calculate the maximum weight of catalyst that one could use and maintain an exit pressure above 1 atm. W = kg 2. (20 points) Write out the Reactor Design algorithm (we've used this method in class to solve all problems) and then solve the equations analytically to determine the catalyst weight to achieve 90% conversion. W = kg 3. (10 points) What is the ratio of catalyst needed to achieve the last 5% (85% to 90%) conversion to the weight necessary to achieve the first 5% conversion (0% to 5%) in the reactor? Ratio =
