Why is there an increase in the activity when the flow of reactants changes and does this implicate problems with mass transference?

Three main phenomena are necessary to be considered in a heterogeneous catalytic process:

External mass (and heat) transport, i.e. reactants from the bulk of fluid (gas or liquid) to the surface of a catalyst, and products from the surface to the bulk of fluid

Internal mass transport , i.e. diffusion of reaction species in pores of a porous catalyst

Internal mass transport , i.e. diffusion of reaction species in pores of a porous catalyst

A good explanation of phenomena occurring in heterogeneous catalytic systems can be found in many textbooks. According to my experience from teaching “Heterogeneous Catalysis in Practice” written by Charles N. Satterfield is one of the most comprehensible.

I agree with you. However, you should also consider the following:
