Transport Effects in Catalysis

This lecture discusses the impact of transport effects on heterogeneous catalysis, emphasizing the interplay between kinetic effects and mass transfer. It covers topics such as external transport through diffusion in boundary layers, the importance of generalized expressions for diffusion, and the influence of changing densities on diffusion coefficients. The lecture also explores the significance of high concentrations in two-component mixtures and the simplifications that can be made in dilute concentrations. Additionally, it delves into the challenges posed by boundary layers and the linearization of Fick's law for various scenarios.
