Research

Over 15% of the world's energy consumption is used for the reprocessing of chemical solutions. Adsorption processes are a cost and energy efficient alternative.

The aim of my work is to evaluate and establish adsorption as an alternative to previous methods of product separation in bioprocesses. I am investigating carbon-based adsorbents for the separation in fermentative biorefinery processes.

Research focus:

• Adsorption of amino acids, dicarboxylic acids and sugars in model solutions
• Adsorption in real fermentation broth (cooperation with Bio.VT)
• Process design and development of a semi-continuous adsorber
• Surface and structure modification of commercial activated carbons
• Characterization of activated carbons by N₂-Physisorption, H₂O-Sorption, Titration, Elemental Analysis, TPD-MS
