Abstract

In this work, the subject is to investigate the ultrafiltration of reverse micellar solutions in order to find the most suited membrane material. Operating conditions such as cross-flow velocity, temperature, flux or transmembrane pressure shall then be optimised in terms of maximum micelle or catalyst retention. Moreover, for an efficient process design, a practical and reliable flux and retention model shall be developed. Finally, the MEUF step will be coupled to the reaction step to obtain an optimised integrated process.

Due to a change in research direction, the focus also lays on the removal of the surfactant used in hydroformylation from the organic phase after the phase separation step via organic solvent nanofiltration.
