Abstract
A model of the FT synthesis in the slurry phase is being developed. It is based on first-order rate expression for hydrogen consumption but considers all relevant hydrodynamic phenomena. The parameters involved in the model equations were estimated from literature correlations and recent experimental results. The basic set of operational conditions was that applied in the Rheinpreussen-Koppers demonstration plant. The computations show that liquid solid mass transfer resistances and catalyst settling can be neglected in larger diameter columns. Gas-liquid mass transfer limitations are also small as long as conventional catalysts and favorable gas velocities are applied. The simulated results are in general agreement with practical experience. 52 refs.
