Lions Sponsorship 2018

In 2018 the Lions Sponsorship was awarded for the fourth time (call only in German). 15 submissions from 8 faculties of the TU Wien have been examined by a jury out of members of the Lions club and the TU Wien. The applications have been evaluated by general and scientific criteria (e.g. demonstration of use of the subsidies, description of the scientific methodology, innovation degree of the work, as well as their potential).

Price Winner Josef Fuchs

Josef Fuchs is PhD student at the Institute of Chemical, Environmental and Bioscience Engineering (research group future energy technology, project group gasifciation and gas cleaning). His research focuses on an innovative process based on the so called Dual Fluidized Bed (DFB) Steam Gasifiation. The DFB Steam Gasification is a well-known process for the thermochemical conversion of biomass into a valuable product gas. Industrial plant have already been built in Güssing, Villach, Senden and Gothenburg. Most plants aim at the production of heat and electricity from woody biomass. Unfortunately, the price for woody biomass increased significantly the last decade. Therefore, Josef Fuchs research focus is the so-called "Sorption Enhanced Reforming" (SER) process. This process is a further development of the DFB Steam Gasification and is based on the usage of limestone as bed material. Proper process conditions allow the in-situ removal of carbon dioxide from the product gas, which leads to a shift in the product gas composition and leads to a hydrogen content in the product gas up tu 75 vol.-%db. Combined with the usage of pure oxygen in the combustion reactor of the process a valuble product gas can be obtained on the one hand. On the other hand a pure flue gas stream consisting of nearly pure carbon dioxide could be gained.

Josef Fuchs will use the price for participation in international conferences (e.g. SEEP2018 in Paisley) and hardware for kinetic modelling of the process.

Special Price Andreas Nagl

Andreas Nagl is PhD student at the Institute of Materials Chemistry and works in the group “Technical Catalysis” supervised by Prof. Föttinger. In his project he works with bimetallic gold catalysts (consisting of two different metal components) for the selective oxidation of (bio-)ethanol.

The catalyst that was developed allows the conversion of ethanol with molecular oxygen as an environmentally friendly oxidant with high selectivity. The products, acetaldehyde and acetic acid are important base chemicals for the chemical industry (worldwide production in the million tons scale) and thus from accessible renewable feedstocks. This means a relevant contribution to the future concept of the “biorefinery” and the reduction of the dependence on fossil hydrocarbons.
Andreas Nagl uses the award for research stays at international institutions and project partners (e.g. BESSY Berlin, DESY Hamburg, ALBA Barcelona, DLS Didcot/UK) where he is observing catalytic processes with Synchrotron radiation. Understanding the catalyst structure and the reaction mechanism is the key to tuneable bimetallic catalysts for industrial application.

Measurement at Diamond Light Source, UK

The B18 beamline allowed fast x-ray absorption spectroscopy (XAS) measurements of the catalyst under dynamic conditions. Industrially relevant processes of the promoter in the catalyst could be studied (publication in preparation).
