The following elementary reaction is carried out in a membrane reactor packed with 200 kg of catalyst. The reaction is carried out isothermally and there is no pressure drop. Below is a sketch of the concentration profile for the same reaction in a conventional backed bed reactor PBR to be used as a reference? A. Suppose B diffuses out through the membrane. Using a dashed line (---) sketch and label the concentration profiles of A, B, and D in a membrane reactor for a moderate value of mass transfer coefficient of B on the figure below, and explain briefly why? B. Now suppose that both B and D can diffuse out of the reactor. Using a dashed line (---)sketch and label the concentration profiles of A, B, and D in a membrane reactor for a moderate value of mass transfer coefficient of B on the figure below. Assume that mass transfer coefficient of both B and D are the same. Explain briefly your results?
