Chapter 14: External Diffusion Effects on Heteregeneous Reactions

Additional Homework Problems

CDP14-AB

  The reaction

    is carried out on a metallic surface and follows Langmuir-Hinshelwood kinetics at room temperature with the corresponding rate law:

However, at higher temperatures the reaction is mass transfer-limited. The reaction currently takes place on a monolith catalyst where 45% conversion is achieved. It is proposed to double the number of plates for the same width and to halve the length of the reactor. What conversion can be expected for

(a) Monoliths operated at low Reynolds numbers?
(b) Monoliths operated at high Reynolds numbers?
