High Energy XRD and GISAXS Operando Studies of the Dehydrogenation Catalytic Reaction in LOHC Technology

We will use HEXRD to study the structure of Pt/Al2O3 catalysts during the dehydrogenation reaction of the liquid organic hydrogen carrier (LOHC) benzyltoluene. The goal is to provide atomic-scale insights on the degradation processes of the catalyst during the reaction. With the new version of our dehydrogenation reactor, we will test both sulphidated and non-sulphidated catalysts to understand why sulphur poisoning improves catalytic activity and reduces the catalyst deactivation; and we will also probe different reactor positions to understand the influence of the different chemical potentials.
