Sels Prof. Dr. Ir. Currently full professor at KU Leuven ， Center for Surface Chemistry and Catalysis, KU Leuven, Celestijnenlaan 200F, 3001 Heverlee Global feedstock supply under pressure due to shortness and geopolitical issues. Current transition of feedstock use implies a change from fossil oil into other resources like gas, coal and biomass. Strategies to convert each of them into chemicals and materials and the challenges associated with that goal are different for each alternative feedstock. Biomass, when sustainably harvested, is considered renewable and may have low carbon footprint. As long as the atom economy of the reactions to convert biomass into chemicals is high, use of biomass is an elegant solution to replace the fossil resources. Reactivity of a molecule is determined by its chemical functional groups. Biomass comprises a collection of beautiful chemical structures: alcohols and carbonyls in carbohydrates, amines in proteins, carboxylic acids and esters in triglycerides, aromatics in lignin and cyclic structures in terpenes. Next to technological challenges in the biorefinery, the emerging task of (bio) chemists is to discover reaction pathways to selectivity convert the original structures into useful ones. While biotechnology is able to deal with biomass feedstock, classic heterogeneous catalysis also will play a great role in that transformations. Even better, taking advantage of both worlds, joint conversions will likely be the best strategy in a biorefinery to produce a handful of chemicals against competitive prices. Since the beginning of the 21st century, a vast literature has developed showing elegant catalytic systems, adapted for the conversion of biomass. In this context, the lecture will give an overview of the catalytic work done in my group over the last couple of years. Points of interest are the role of catalysis in the biorefinery of lignocellulosics with focus on the recovery of carbohydrate pulp and lignin-derived chemicals, and their conversion into useful products and materials.

Research Professor (Oct 2017) at Center for Surface Chemistry and Catalysis, KU Leuven, Celestijnenlaan 200F, 3001 Heverlee Zeolites are well-known and durable catalysts in petrochemical and refinery operations. In the catalytic conversion of bio-derived molecules, or the conversion of (natural) gas, these microporous materials have a role to play as well. Two topics will be discussed to demonstrate the importance of adapting zeolite technology (incl. synthesis) to the development of sustainable processes. The first will be in the context of bioplastics. The synthesis route from sugars to certain polyester plastics is inefficient and I will demonstrate how (petrochemical) zeolite concepts have been successfully introduced to overcome some of the barriers in this field (BEA). In the second part, the focus will be put on the synthesis of zeolites itself, this time in the context of the methanol-to-olefins reaction (MTO). This reaction, known since the 1980s, is getting industrially implemented at high speed. The commercial catalyst is a silicoaluminophosphate, but aluminosilicates (e.g. SSZ-39, AEI) could become significant competitors, especially when considering that such zeolites are being commercialized for the selective catalytic reduction of NOx in exhaust gas. A topological link between both applications will be explored. A third and final topic will showcase the discovery of a new synthesis route to the elusive GME zeolite. The new material, CIT-9, is fault-free and its synthesis presents a truly unique case of conditional and isomeric cis/trans sensitivity related to the organic structure directing agent. Variable temperature XRD was used as well to explain the remarkable transformation of GME to AFI at 280 °C.
