Abstract
One major hurdle for the implementation of a hydrogen-based energy system is the storage and transport of hydrogen. In this context, liquid organic hydrogen carrier (LOHC) technology is a promising solution. Besides catalytic activity, the formation and detachment of hydrogen bubbles affect significantly the dehydrogenation rate in the multiphasic reaction by enhancing mass transfer of the reactants. An active catalyst state is achieved if complete liquid filling of the pores of the catalyst is prevented, which can happen during the shutdown procedure of the reactor, an effect known as nucleation inhibition. This study investigates the effect of nucleation inhibition on the hydrogen release process of the LOHC compound perhydro benzyltoluene and develops suitable reactivation strategies. It is shown that straightforward techniques, such as a brief reduction in pressure, a short temperature increase, or a mechanical impulse, can fully restore the activity of the catalyst.
