Heterogeneous catalysis in pulsed-flow reactors with nanoporous gold hollow spheres

•A novel application of the Lattice Boltzmann Method to the study of pulsed reactive flows is proposed.•LBM proves accurate and reliable in the transitional Knudsen flow regime, i.e. 0.1 < Kn < 1.•The reactivity is found to increase with the Knudsen number of the flow.

We present a novel application of the Lattice Boltzmann Method to the study of pulsed reactive flows in transitional Knudsen number regimes, namely 0.1
