Research Interests 

 

Liquid-liquid Systems and Intensification

These research projects are concerned with the scale-up of intensive liquid extraction processes, focusing on fundamentals of drop motion behavior (as discrete drops and in swarms), modeling of mixing and mass transfer in liquid-liquid contactors; fundamentals of electrically charged drop motion in liquid-liquid systems; interfacial mass transfer, equilibria and drop behavior in biological product extraction systems; ionic liquid solvents - synthesis, physical property measurement, partition, and applications; novel intensive reactors for biodiesel production.

 

Enzymatic Catalysis

This research focuses on the process intensification of enzymatic biotransformation processes in two phase liquid systems and associated downstream separations. Applications include enzymatic modification of natural oils and fats via the production of fatty acids by hydrolysis. This approach is especially of potential value for splitting of sensitive triglycerides, unconjugated systems (which may undergo thermal degradation), hydroxylated fats and oils (which may dehydrate) or polyunsaturated oils with high iodine numbers (which may polymerise). Another aspect involves new techniques for enzyme and cell stabilization, developed in collaboration with clinical biochemists which may provide some exciting opportunities for commercial diagnostic applications and for industrial enzymatic catalysis.

 

Ion-exchange and Adsorption

This research focuses on ion-exchange kinetics & equilibria in synthetic and natural ion- exchangers and on simultaneous ion-exchange and bioregeneration in zeolitic ion exchangers. Of special interest is the intensification of the supply of oxygen to aerobic microorganisms adsorption and bioadsorption processes for waste water treatment and potable water pre-treatment, development of combined physical and biological separation processes, and the development of new adsorbents and exchangers based on natural materials.
