Analytical and computational study of cascade reaction processes in catalytic fibrous membranes

Multistep catalytic reactions use two different catalysts for the A → B and subsequent C reaction, respectively. Often employed are chemically incompatible, such as acid–base systems, which prohibits simple mixing in one solution. In this work, we study efficiency of reactors where incompatible sites immobilized on fibrous membranes. We compare a lattice Boltzmann based solver advection–diffusion–reaction equation, random walk particle tracking method theoretical model to investigate reaction function dimensionless control parameters: Péclet Damköhler number. find that, while decreases with higher flow speed (due reduced time), total production nevertheless increases due mass flux most cases. Our results further show even at high speeds, spatial proximity efficiency, supports recent experimental efforts locate both single fiber side-by-side geometry.
