About this position
This postdoctoral position at CNRS is part of the ANR TOOLS4HYBCAT project on hybrid catalysis for converting biomass-derived sugars into 5-hydroxymethylfurfural (5-HMF). The selected researcher will focus on the chemical-catalysis side of a coupled process that transforms D-glucose into D-fructose enzymatically and then dehydrates fructose into 5-HMF using acid catalysis.
The main scientific challenge is to select suitable chemical catalysts, immobilize them on appropriate supports or directly on reactor surfaces, and evaluate their performance under different reactor configurations. The work will compare catalyst behavior in conventional batch conditions, then in monophasic and biphasic reactors, before assessing the overall performance of the hybrid triphasic microrreactor.
The project sits at the interface of enzymatic catalysis and chemical catalysis, aiming to combine both reaction types in a single integrated system despite different operating conditions. The microrreactor uses two aqueous phases separated by an organic phase that enables selective transfer of the reaction intermediate, with the broader goal of controlling reactions and mass transfer within the device.
The postdoc will contribute to literature analysis, catalyst screening, immobilization strategy development, reactor testing, performance evaluation, and dissemination of results through project meetings, scientific reports, and publications. The enzymatic part of the process is already being developed through a PhD started in September 2025, and this position completes the chemistry component of the hybrid route.
