Abstract

Abstract: Liquid‐filled pores of Fischer‐Tropsch catalyst lead to slow diffusion of the reactants and can cause internal transport limitations leading to a significant decrease of selectivity and productivity. As an approach to overcome these limitations, transport pores can be added to provide an additional pathway for mass transport. In this work, a 3D isothermal model was developed, which takes the effect of concentration gradients within the transport pores into account. A comparison with a 1D model showed, that a description by a 3D model is necessary for transport pores with diameters larger than 10 µm. Abstract : In this work a 3D isothermal model of reaction and diffusion in catalyst layers with transport pores is developed for the Fischer‐Tropsch synthesis which was introduced in the 1920s. A comparison to a 1D model is drawn, showing the influence of the transport pore diameter on the yield.
