In the current study, the interaction of convection, diffusion and a surface reaction is simulated with the help of an advanced two-phase lattice Boltzmann method in the context of a Fischer-Tropsch synthesis. In our case of interest, carbon monoxide and hydrogen are converted into liquid hydrocarbons with the help of a catalyst deposited on the internal structures of a structured reactor. The liquid product and the heat of reaction are carried away from the reacting surface with the help of a fully wetting liquid. A dedicated FTS kinetic model was implemented on the reactive surfaces. Reaction rate and conversion are calculated in terms of the dimensionless Péclet and Damköhler numbers.
