Van Vuuren, D S; Heydenrych, M D

In the multicomponent model developed for a Fischer-Tropsch slurry reactor, the water-gas shift reaction is assumed to be in equilibrium. This is supported by literature data on iron-based catalysts above 523 K and synthesis gas conversion above about 50%. A Schulz-Flory product distribution is used. Investigation of the effects of back-mixing and interphase mass transfer using the model shows that, although the mass transfer rates in full-scale reactors are fast compared with reaction rates, the ratio of the mass transfer rates of reactants and products is important in determining gas velocity and gas hold-up and hence reactor performance.
