ABSTRACT:

Objective is to evaluate the potential of supercritical fluid extraction for separating the catalyst slurry of a Fischer-Tropsch (F- T) slurry bubble column reactor into a wax and a concentrated catalyst slurry that is ready for recycle/regeneration. The automated apparatus was evaluated using a toluene-petroleum pitch system. The Statistical Associating Fluid Theory (SAFT) equation will be used to fit the VLE and LLE data for F-T wax-solvent systems; this equation was successful in predicting both phase compositions and average molecular weight distributions.
