Gas purification

Due to the tuneable solvation properties of ionic liquids they can be used as extraction agents. In desulphurization of diesel ionic liquids have been tested already. In gas phase desulphurization of gaseous feeds the use of SILP materials proved to be very promising. In a current research project the sulphur model compound butan-1-thiol was removed from a toluene feed. SILP materials were tested both in slurry and fixed-bed reactors.
