The reversible isomerization

A B

is to be carried out in a membrane reactor (IMRCF). Owing to the configuration of species B, it is able to diffuse out the walls of the membrane, while A cannot.

  1. What is the equilibrium conversion assuming that B does not diffuse out of the reactor walls?

  2. Plot the conversion profiles to compare a 100 dm3 conventional PFR with a 100 dm3 membrane reactor. What statements or generalizations can you make? What parameters have the greatest effect on the shape of the exit conversion plots in part (A)?

  3. Plot the conversion and species concentrations and the molar flow rates down the length of the reactor.

  4. Vary some of the parameters and write a paragraph describing your results.

  5. Discuss how your curves would change if the temperature were increased significantly or decreased significantly for an exothermic reaction and for an endothermic reaction.
