Catalysts are the workhorses of chemical transformations in the industry. They offer often a green alternative path for reactions, favored by reduced activation energy but following a more complex path. Temporal Analysis of Products (TAP) is a pulsed transient technique able to extract intrinsic kinetic data of this complex path over a catalyst from reaction-transport data. Since the configuration of the catalyst could be shrunk to a single micron-sized catalyst particle, the characteristics of multi-particle systems for TAP are of interest. A shadowing effect has been studied by modeling the TAP reactor with a parabolic partial differential equation (PDE). First results will be shown solving the PDE with a Monte Carlo method and the finite element method.
