Problem 6 ( 25 points). m-xylene is reacted in an isothermal plug flow reactor over a ZSM- 5 zeolite catalyst where the following first order reactions occur: mxylenek1benzene+methanemxylenek2pxylenek1(650C)=0.29s1k2(650C)=0.82s1Ea1=20kcalmol1Ea2=10kcalmol1 The feed is 50%m-xylene and 50% inert at a v=150Ls1,Ct0=0.06molL1. a. Find the PFR volume and space time required to obtain 80% conversion of m-xylene at 650C. Plot the concentrations vs. V. What is the p-xylene yield at 80% conversion? b. At what temperature would you run a 2000 L CSTR to maximize the formation of p-xylene? What would the p-xylene concentration be at this temperature in the reactor? c. Write out (but do not solve) the design equation if instead of a plug flow reactor, you used a semibatch reactor (feeding in m-xylene with inert, but with no outlet stream). What additional information would you need in order to solve for the concentrations in the reactor
