The concept of an integrated biorefinery concept starting from the wood as raw material, represents a possibility for new sources for the production of chemicals as an alternative to conventional fossil fuels. Lignin is a complex polymer in wood and lignocellulosic biomass and the largest natural renewable source of aromatics represent. Cleaving the lignin without driving the depolymerisation too far ahead is crucial for the production of valuable products for the food and pharmaceutical industries (for example vanillin or hydroxybenzaldehydes). Different routes are currently being studied worldwide for the successful depolymerization of lignin. The electrochemical cleavage of lignin is characterized by its mild reaction conditions and therefore is condisered a green process concept. The master / bachelor thesis is part of the SuBiCat project (Sustainable Biomasses Catalysis; and the Cluster of Excellence "Tailor-Made Fuels from Biomass". Important points of research will: - Innovative solvents for the eletrochemical depolymerisation of lignin and for wood pretreatment - In situ extraction of the products through liquid liquid extraction and membrane processes (FVT collaboration) - Innovative electrochemical reactor setups - Analytical methods for lignin and product characterization (SVT Collaboration) - Combination of electrochemical and enzymatic processes in collaboration with the (Biotech collaboration) If you have interest on both the experimental procedure as well as on the development of analytical methods, you can easily contact me by phone or by e-mail.
