Background and activities
Hilde Venvik is part of the Catalysis group at the Department of Chemical Engineering, NTNU, the largest catalysis group in Norway and the main arena for education of PhD’s and MSc’s for Norwegian industry and research organizations. As of 2015 the group consists of five Faculty members (Edd A. Blekkan, De Chen, Anders Holmen, Magnus Rønning, Hilde Venvik), ~20 PhD students and ~5 postdoctoral fellows. The group is an integrated NTNU/SINTEF research laboratory where NTNU-staff collaborate and share facilities with ~10 permanent researchers employed by SINTEF Materials and Chemistry, Process Chemistry Department. This collaboration is institutionalized through the KINCAT Gemini centre (NTNU/SINTEF twin research centre). Together with the catalysis groups at the University of Oslo and SINTEF, the group was part of a Centre for Research-based Innovation (Innovative Natural Gas Processes and Products – inGAP) during 2007-2015
Hilde Venvik was between 2010 and 2015 NTNU Director of the Gas Technology Centre NTNU-SINTEF (GTS). GTS was established in 2003 and is the largest centre for gas technology research and education in Norway. GTS exploits the multidisciplinary synergism of NTNU and SINTEF’s expertise encompassing the entire value chain from the energy source to the end user, and acts as a common interface in gas technology R&D between NTNU/SINTEF and the market.
1. Catalysts for conversion of natural gas and biomass to fuels and chemicals, including hydrogen. This includes reactions relevant to synthesis gas production, such as steam reforming, catalytic partial oxidation, oxidative steam reforming and gasification, and the conversion of synthesis gas to methanol, dimethyl ether and Fischer-Tropsch products, as well as hydrogen via water-gas shift (WGS).
2. New reactor concepts for catalytic conversion such as monoliths, microstructured reactors and membrane reactors, to enable process intensification and process control.
3. Catalytic phenomena important to metal dusting corrosion, e.g. carbon formation from CO.
4. Surface science by combined experimental (scanning probe techniques, surface spectroscopy and electron diffraction and electron microscopy) and theoretical (microkinetic modelling, density functional theory) approaches, related to (1-3). Adsorption phenomena on cobalt, palladium, involving CO, H2, CO2, O2, H2O, CH3OH, C2H4, H2S, and more, are of particular interest
