16. Reactions on nanostructured and microporous surfaces
Abstract : Interactions between surfaces and molecules play a central role in various fields where catalysis is one example. In order to understand different surface processes, physicochemical characterisation of the surface materials and molecules is required. READ MORE

17. Nitrous Oxide Formation over Zeolite-based Catalysts during Ammonia-SCR: The Effect of Framework Structure, Acidity, and Copper Content
Abstract : The emission control of anthropogenic nitrous oxide (N2O), a by-product formed through fossil- and renewable fuel combustion, agricultural activities, and industrial chemical processes, has attracted large considerations due to its substantial contribution in global warming and ozone layer depletion. Selective catalytic reduction with ammonia (NH3-SCR) is the most prevailing technology for the abatement of nitrogen oxides (NOx) in the exhaust gases from lean-burn processes, with the possible formation of N2O.

18. Structured Nanoporous Materials for Biogas Upgrading
Abstract : Porous materials have shown potential for solving one of the significant challenges to sequestering CO2 gas from point sources. Microporous materials, zeolites and metal-organic frameworks (MOFs) are porous materials with tailorable adsorptive properties to develop higher performance for an energy-efficient CO2 separation.

19. Catalyst Design for the Valorisation of Biomass-derived Furans into Aromatics
Abstract : Anno 2023, mankind must strive towards a more sustainable chemical industry; one that does not solely rely on fossil fuels but also utilises renewable feedstocks such as biomass. Biomass can be catalytically converted into commodity chemicals such as aromatics, through intermediates like furans. READ MORE

20. On the use of periodic operation for improvning chemical processes
Abstract : In this thesis, some methods of improving the product distribution from chemical processes are compared. The first two parts contain an experimental investigation of how the product distribution of a process is influenced by the choice of catalyst. READ MORE
