Fischer-Tropsch (F-T) synthesis produces a broad range of products (known as waxes) consisting primarily of paraffins, olefins, and alcohols with carbon numbers ranging from 1 up to about 200. Slurry bubble column (SBC) reactors are receiving increasing attention as the preferred way to carry out the F-T reaction. However, the separation of the reactor catalyst from the wax product is an issue that has yet to be satisfactorily resolved. Vapor and liquid equilibrium compositions have been measured for the hexane + hexadecane and the hexane + 1-hexadecanol systems at temperatures from 472.0 K to 623.0 K and pressures from 6.2 bar to 46.4 bar. A continuous-flow apparatus was used both to minimize possible thermal degradation and to accurately measure the lower hexadecanol concentrations in the vapor phase. Mixture critical pressures and compositions were also measured. Results indicate that the addition of the hydroxyl group to the C{sub 16} hydrocarbon backbone significantly affects the phase behavior with hexane.
