ABSTRACT:

In pursuit of the diffusion coefficients of Fischer-Tropsch products in supercritical fluids, the objectives for this quarter were to continue the work on effective density measurements. Some data were to be obtained and calculations of effective diffusivities were to be made. Once the effective diffusivity is known, then also knowing the molecular diffusivity, the tortuosity factor can be obtained. The porosity has been determined from independent experiments. Knowing the tortuosity and the porosity the only property that is needed to back calculate the effective diffusivity in a wide range of reactor conditions is the molecular diffusivity at those reaction conditions.
