Background and goal of project
Noble metals such as platinum and palladium are common used catalyst for hydrogenation, hydro-genolysis and Fischer-Tropsch synthesis. However, the high cost and the limited availability of those metals have promoted a search for new types of catalyst. Promising results have been obtained using tungsten and molybdenum (W & Mo) carbides which will be used during this study as replacement for noble metal catalyst for the deoxygenation of fatty acid.
Supported nanoparticles of Mo-carbides and W-carbides can convert triglyceride-based feedstock to alkanes and alkenes. Interestingly, the W-carbides did show a high selectivity (>50%) towards the higher value substrate (alkenes), while the Mo-carbides were more active. Therefore, the aim of this research is to investigate property performance relationships for mixed (MoW-)carbides for the deoxygenation of triglyceride based feedstock’s.
Student projects envisioned
This research project involves mostly lab work. Catalyst synthesis and characterization techniques like XRD, TEM, N2 physisorption and chemisorption are applied. So far the deoxygenation reactions are evaluated in a batch system. However, we are aiming to set up a plug flow system in the following year.
