%X Both membrane types show a significantly enrichment of aromatic components (toluene or benzene) in the course of the pervaporation process (from 20 wt-% in the feed to about 55 wt-% in the permeate). The fluxes are in the range of 1 kg/hm² at a feed temperature of 80 °C. The separation of a benzene/cyclohexane mixture was also successful at 50 °C. In all cases higher fluxes were obtained with benzene/cyclohexane feed mixtures than with toluene/ heptane mixtures. Also in multi-component feed mixtures, benzene exhibit the better permeate rates.
