Description :
Development of a hydrogen economy requires efficient hydrogen storage and transport technologies. For automotive applications, high hydrogen storage densities (>5.5 wt %) are also necessary. The use of liquid organic hydrogen carriers (LOHCs) for hydrogen storage has received attention recently because they meet the automotive density demands and they can use existing infrastructure for transport and storage. LOHCs deliver the hydrogen on-board the vehicle by catalytic dehydrogenation whereas the spent LOHC is regenerated by hydrogenation off-board the vehicle. This presentation provides an overview of our recent results on the kinetics and catalysis of heterocycle hydrogenation/dehydrogenation reactions. In particular, we show how structure sensitivity of dodecahydro-N-ethylcarbazole dehydrogenation over Pd catalysts at low temperature (< 200 °C) impacts hydrogen recovery. The importance of including a heteroatom (N) in the polycycle is also demonstrated by comparing the dehydrogenation kinetics of dodecahydrocarbazole and dodecahydrofluorene. Finally, some of the mechanistic and kinetic details of the reactions are discussed, based on a combination of experimental results and DFT calculations.
