Abstract

Apart from hydrogen logistics, stationary hydrogen storage applications using Liquid Organic Hydrogen Carrier (LOHC) systems are also of significant interest. In contrast to the traditional use of separate hydrogenation and dehydrogenation reactors, our so-called oneReactor technology offers the advantages of a simpler storage unit layout and high dynamics in switching from hydrogen charging to hydrogen release. Here we report repeated hydrogenation and dehydrogenation cycles with one batch of liquid carrier for LOHC stability tests under defined hydrogenation and dehydrogenation conditions. We demonstrate up to 13 hydrogenation/dehydrogenation cycles over a total of 405 h of operation including two long dehydrogenation sequences over weekends. In general, longer dehydrogenation runs, i.e. exposure of the LOHC to catalyst at low hydrogen pressure and elevated temperatures (> 280 °C), showed negative effects on both activity of the subsequent cycles and by-product formation. Concerning catalyst activity and hydrogen productivity, stable productivity was achieved (within 3 to 9 cycles) under all conditions tested. Longer hydrogenation runs led to significantly higher stability of the reaction system.
