PPT-1. Mass transfer of A to surface

2 Diffusion of A from pore mouth to internal catalytic surface 3 Adsorption of A onto catalytic surface 4 Reaction on surface 5 Desorption of product B from surface 6 Diffusion of B from pellet interior to pore mouth. 8 362 Overall mass transfer coefficients Experimentally the mass transfer film coefficients k and k x are difficult to measure except for cases where the concentration difference across one phase is small and can be neglected Under these circumstanc Analogies.
