Details

Structuring of catalysts and reactors over a wide scale allows the decoupling of intrinsic and extrinsic phenomena, such as reaction kinetics, mass and heat transport processes on catalyst and reactor level and hydrodynamics and enables the optimization and fine-tuning of the reactor operation. Multifunctionality using membranes or an additional catalytic function can be beneficial. The Fischer-Tropsch synthesis is used as an example to illustrate the potential of structuring to improve mass and heat transport, and optimize reactor operation. A bifunctional FTS catalyst is presented for the small scale direct conversion of biomass derived syngas to liquid products (BTL), and a membrane catalyst for a highly selective p-xylene production.

About the speaker

Freek Kapteijn (1952, Amsterdam) graduated in 1974 at the university of Amsterdam in Chemistry and Mathematics. His PhD on the metathesis of alkenes was received at the same university. As postdoc he focused on Coal Science and Heterogeneous Catalysis. In 1987 he received a tenured position at the University of Amsterdam. In 1992 he moved to Delft University of Technology, where he was appointed 'Anthonie van Leeuwenhoek' professor in 1999. He has assumed leadership of the Catalysis Engineering section in 2008.

Professor Kapteijn had visiting appointments in Nancy, France (Villermaux, ENSIC) and Zürich, Switzerland (Prins, ETH), and is guest professor at Zhejiang Normal University, China since 2008.

He is co-author of over 450 publications in scientific journals, and thesis advisor of over 42 PhD students.

Current interests include the synthesis, characterization and application of structured catalysts (metal-organic frameworks, zeolites, monoliths, catalytic membranes) in multiphase and multifunctional conversion processes, adsorption and diffusion in zeolites, MOFs and their membranes, and transient kinetics.

The related specific applications of heterogeneous catalysis cover selective hydrogenation and oxidation, hydroisomerization, N2O decomposition, Fischer-Tropsch synthesis, MTO and fine chemicals production. Energy efficient alternatives for alkane-alkene and CO2-CH4 separation and adsorptive heat pumps are subject of development. Light-matter interactions are a special topic with MOFs, targeting photocatalysis and water splitting, next to their use in light generation.
