PostDoc position in In-situ product recovery integration to microbial electrosynthesis

Power-to-Chemicals and Power-to-Fuels processes are the future of the chemical industry. The chemical industry is a major greenhouse gas emitter. To meet their GHG emission reduction target, the chemical industry must use alternative carbon sources (e.g. CO2) and electricity-based processes (Power-to-X). The perspective of a highly electrified chemical industry where renewable feedstocks and energy are the basic ingredients of chemicals is very appealing to many societal, industrial and governmental stakeholders. Microorganisms are able to grow on electrodes and utilize renewable electricity to convert CO2 to valuable chemicals. This Power-to-X process is called microbial electrosynthesis (MES), and is the focus of this postdoctoral project. This postdoc project is part of a larger project (2 PhD and 2 postdocs) and a consortium composed of four international companies, which all together will develop a scalable MES process that produces hexanoic acid (C6, a major base chemical) from CO2 and renewable electricity. Our distinctive approach will elucidate how to avoid rate and yield limiting steps from micrometer to meter scale, by guiding experiments and reactor/electrode design with comprehensive multiscale modelling. We will use the attained insights on the working mechanisms of MES to develop a scalable process capable of producing pure hexanoic acid from CO2 under industrially relevant conditions.

The task of the postdoctoral researcher will be to develop a clean, scalable process for recovery of hexanoate (C6) that is produced by MES. This should lead to the C6 acid in high purity and yield. Anion-exchange will be the primary method for downstream processing. The postdoctoral researcher will determine and model adsorption and desorption, predict conditions to increase performance, further work out the recovery process, experimentally integrate it with an established MES set-up, and fully characterize the overall system. Techno-economic analysis will be used to guide the direction of this work.

The ideal candidate

Department of Biotechnology

Innovation is crucial to fulfil the potential of industrial biotechnology for sustainable production of fuels, chemicals, materials, food and feed. Similarly, scientific and technological advances in environmental biotechnology are needed to enable novel approaches to water purification, and ‘waste-to-product’ processes thus contributing to a circular economy. Increased fundamental knowledge encompassing enzymes, microorganisms and processes are essential for progress in this field. The Department of Biotechnology covers this research area and, based on new insights, selects, designs and tests new biobased catalysts, micro-organisms, and processes.

The position is available in the section Bioprocess Engineering.
