Consider a porous catalyst with a series reaction represented as A → B → C Write governing equations for A and B. Express them in dimensionless form. How many dimensionless groups are needed? Solve the equations for a case where the dimensionless concentrations at the catalyst surface are one and zero for A and B, respectively. Note that both concentrations are normalized with the concentration of A at the surface. Calculate the dimensionless gradient for these two species at the surface. From these expressions calculate the yield parameter defined as S = −(dcB/dξ)/(dcA/dξ) at ξ = 1 What is the significance of this parameter? Plot it as a function of φ. For a high selectivity to B, would you operate with a low φ or a high φ.
