Chapter 18. Mass Transfer with Reaction: Porous Catalysts

Learning Objectives

After completing this chapter, you will be able to:

• Use the equation of mass transfer to set up models for porous catalyst a where diffusion and reaction are occurring in parallel.

• Solve the equations for simple 1-D problems analytically for first-order and zero-order reactions.

• Use semi-analytic tools to solve problems involving nonlinear reactions.

• Understand the concept of effectiveness factor and how diffusion masks the true kinetics.

• Learn and use the method of orthogonal collocation to solve nonlinear diffusion-reaction problems in 1-D.

• Learn simple finite difference methods to solve 2-D problems in regular geometry.

• Model diffusion with reaction with heat effects ...
