Computational study of multi-step catalysis in fibrous membranes — •Gabriel Sitaru and Stephan Gekle — University of Bayreuth, Germany
Multi-step catalytic reactions using incompatible catalysts in a one-pot are notoriously difficult to realize in technical settings. In this work, we investigate the potential of fibrous membranes as catalyst carriers by analysing the interplay of three different time scales: advection, diffusion and reaction.
The time-dependent concentration profiles throughout the reactor are computed using a Lattice-Boltzmann based solver for both the advection-diffusion and the Navier-Stokes equations. Using this model it is possible to study various parameters such as flow velocity or different geometries in order to maximize the reaction efficiency.
