The Role of Intraparticle Diffusion in Kinetic Model Discrimination: Proof of Concept Testing for Methanol Dehydration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...
